Thinker ready to be unleashed upon the world,

This conversation is closed.

Why are the alternate power sources not being implemented on a world-wide scale? There is a tipping point and we must be close by now!!!

Solar panels
Wind Turbines

We all see the signs of the world changing. Ice caps disappearing, mega storms, tempature rise, ect.
Yet we are more concerned with royal babies, wars, and profits.
We will have none of that if this planet stops supporting life as we know it.
This is a back burner issue always used for politics but never solved by politics.
Turn the heat up on this, the Earth is!

    • Aug 21 2013: I don't now about fossil fuel subsidies in your country (the US, I presume?), but we don't have those where I live, and fossil fuels are still the cheapest option by a wide margin (on the order of twenty times cheaper for wind, in fact, and solar is even worse).

      Nuclear is also not all that harmful, assuming the plant is built properly--they actually release less radiation than burning coal (which contains trace radioactive elements). Water draw is very dependent on reactor design, and is typically not much of a limiting factor, especially near the ocean.
      I don't really see how it damages the locals either, except lowering property values somewhat; it also provides jobs to partially make up for it.
      A bigger issue is that in a lot of countries, you can't build nuclear reactors without being blamed for trying to develop a weapons program.

      Also, if you try to have every building produce half its power via solar panels, you'll suddenly find you don't even have enough electricity for the toaster and the boiler to work simultaneously--solar power has a piss poor output even during high noon, and power storage technology leaves a lot to be desired.
      A solar panel does pay for itself over the course of a few years on lower latitudes, but the power output is nothing to write home about. Its useful for heating water (through direct heating, no electricity involved), but doesn't particularly shine at anything else.

      I've covered electric cars responding to someone else bellow, and don't feel like repeating myself...
      Natural gas cars may have potential, I honestly wouldn't know, and don't feel like doing the research at the moment.

      Frankly, if the renewables were economical, we'd be using them already, environmentally friendly or no.
      • Aug 22 2013: Are fossil fuels cheaper than renewable? It depends. If the law was that you must clean up your own mess, so that all of the toxins put into the air, water and land must be cleaned up, and you are liable for all the damage done by those toxins whether it is asthma, cancer, or acid rain, or even global warming, then no, Fossil fuel is not cheaper. No one denies that asthma rates are a direct result of burning coal. No one denies that acid rain is a result of the burning of fossil fuel. No one denies that the increased CO2 in the air is changing the chemistry of the atmosphere and having a deadly effect on the ocean. The idea that people could argue that fossil fuel is cheaper while ignoring the costs of all the damage done and the costs of cleaning up the mess is extremely offensive.

        Burning fossil fuel while not cleaning up your mess is akin to rape and pillage of the Earth. The Earth is 4,600,000,000 years old and in just the last 150 years of burning fossil fuel we have had a very dramatic effect on the environment of this planet.

        This is also true of nuclear. Yes, on a whole nuclear seems much, much better than coal, yet then we have a Chernobyl, or a tsunami in Japan, or a 3 mile island and then we see how incredibly expensive one catastrophe can be with nuclear.
        • Aug 22 2013: I agree that burning coal comes with some nasty side effects, global warming or no, but natural gas is a lot friendlier in that regard. Aside from the CO2 and some water vapor, there are no byproducts at all.
          Of course, at 20 times cheaper, you can still fund a lot of cleanup and still have it be less expensive...

          As for nuclear, all those leaks you mentioned are a result of bad engineering, not some fundamental problem. Chernobyl was the only one that actually managed to do any major amounts of damage, and that's because it was an old Soviet era piece of garbage. By the way, in the current environment around the reactor, wildlife is actually doing better than in any comparable region in Eastern Europe, because apparently radioactive fallout isn't as bad for them as human presence...
          Honestly, chemical plants working with dangerous materials have a much worse track record (and not half the regulations), and coal mines kill more people every year, and no one seems to bat an eyelash at those. Go figure.

        • Aug 22 2013: Your view on the issue is very US specific.
          I can tell on good authority in other countries, where fossil fuels aren't subsidized, they're still a lot cheaper. You could try to factor in air pollution for coal all you want, but natural gas burns very cleanly, and in most countries, is priced similarly to coal (often being slightly cheaper).

          In many of those other countries, big business doesn't own half the government like it does in the states (there are always lobbyists, but in most of the world they haven't taken root quite as well as in the US), and yet most energy production is still in fossil fuel simply because renewables don't deliver any bang for your buck.

          You can't suppress a technology, not on a global scale anyway. If there is profit in developing it, someone, somewhere outside your control will develop and implement it anyway.
          Renewables aren't failing due to some conspiracy, or suppression, they're just uneconomical. Fossil fuel corporations don't have to do a thing, renewables are failing under their own power.

          Grid level operating costs in cost per unit of energy. Cost for installation and/or replacement of existing infrastructure is not factored in.
          You'll find that compared to fossil fuels and even nuclear, the renewables will put a hole in your pocket. In most countries, fossil fuel and nuclear aren't subsidized either, so you can't put the blame on that.

          Hydro and thermal require you strike lucky on geography. They're great if they're available, but that's a big if.

          Sun and wind are just plain ineffective.
          Having no control over the on/off switch really hurts, and their output is just pathetic for price spent. They currently need a 500% improvement to match nuclear, and a 2,000% increase to match coal or gas, under a best case scenario.
          Unless there is some exponential growth in the field I'm not aware of (and everything I know about engineering claims there isn't), they're just not realistic contenders. Especially in developing countries, which don't have such large sums of cash to throw away on inefficient electric production.

    Sep 5 2013: Mr. Kable
    I can appreciate your passion for renewable energy and the promises made by it's most outspoken proponents.
    In the past, I too became a passionate spokesman for causes that portended great salvation for troubled humanity.
    In old age comes the wisdom of .unintended consequences. Many comments in this conversation have addressed those perceived consequences. Are they all correct? Maybe not, however too many will be. I am not against renewable energy generation, in my own area, these resources have been integrated into a viable plan to provide power energy at a reasonable cost to consumers. That is the best one can hope. Maybe, in a few hundred years, technology will provide a new source of energy that will meet all the requirements of all. One can only hope.

      Sep 9 2013: Well thank you very much Mike. I really do appreciate it and have given thought to such consequences, environmentally, of course. I can't put a monetary value on our survival or the earths survival. I immediately think solar panels would increase global temperatures due to the reflective surface. Tidal and Hydro-Electric would interfere with the ecosystem IF implemented in a plan that hasn't been thoroughly thought out. As for Wind, I don't really see anything besides one breaking to peices and crashing to the ground. Nature is strong and will work around the turbines without hesitation, as long as we don't use paint that is poison or materials that rust. Which is all possible we just have to stay committed to it.
  • Aug 24 2013: Nadav Tropp,

    I agree that nuclear compares very favorably to fossil fuel, even so it is a very hard sell and for good reason. The people living near fukushima have lost everything, likewise Chernobyl. No one ever considered the Japanese to be sloppy engineers.

    Also, the fact that you could use the money saved using coal or natural gas to clean up the disaster they cause is irrelevant, the fact is they don't use that money to do that.

    My mother lives in an area that was in the midst of a debate over whether to have fracking or not. Every day I was emailed one point of the contract. Never once did it say anything to the effect that they would clean up their mess. Once the water supply is poisoned the land is ruined. Who cares if you are getting royalty checks from the natural gas if your land is now ruined.

    An ounce of prevention is worth a pound of cure. The potential money from fracking and the protections the company was willing to agree for up front was woefully short of what would be fair compensation for the possible damage.

      Aug 24 2013: in bhopal, a chemical plant released a gas that killed and injured thousands. in derweze, turkmenistan, a natural gas well burns for 40 years now, releasing sulphuric acid contaminated carbon dioxide. it is not dangerous to humans nearby only because there are no humans nearby.

      unless you want to stop all chemical plants and all fossil mining too, lamenting about fukushima is not rational. it is a very minor accident that is merely an inconvenience for those that had to move.

      and about japanese engineers. i assume you don't know too much details about the accident itself. i'm an engineer, and i followed the events in detail. fukushima was a mindbogglingly sloppy design, with at least 5 design decisions that i could not believe. i still don't understand how can anyone come up with such a design, or approve it.

          Aug 25 2013: maybe you should educate yourself on how radiation works. 99.999% of the human population got less radiation from fukushima than from eating a banana.

          i don't have to be an expert. it is enough if i read the experts. which i did. i followed 3 expert blogs, one of them was a leading hungarian nuclear physicist.

          health effects of fukushima are negligible. i'm not wasting more words on that, the material is out there, this is not up to debate.

          Aug 26 2013: You realise the 985000 is projected deaths that might possibly be attributable to Chernobyl up to 2056. That many people die because of natural disasters several times each year. I wonder how many deaths will occur due to wind turbine construction and operation in the same time frame.

          It's not impossible you just need to do some science and compare cancer rates between equivalent populations. Even accepting the number from your new link 25000 deaths from the whole industry isn't that many. How many deaths do you think have occurred in agriculture in the same time period? Or in Mining?

          Aug 27 2013: You don't need to track individuals to do statistical analyses. You compare cancer rates in exposed areas to cancer rates in similar populations that weren't exposed. Samples from the more densly populated parts of Australia would make a good control group
          Radiation poisoning 101
          Other than strontium radiation poisoning occurs as the accute effects of exposure to gamma and beta radiation. Damage to DNA may cause development of cancer susequent to acute exposure but the chances diminish with time as long as further exposure is avoided. Strontium is a special case as its chemical similarity to calcium causes deposition in bone tissue so exposure to strontium radio-isotopes must be monitored in the long term as it is hard to remove the strontium once deposited.
          Thats from my own Physice text.

          Aug 27 2013: What about all the people that die each year from respiratory diseaes due to exposure to dust from agricultural land, how many people die from malaria from mosquitos that breed in irrigation ditches?. By isolating chernobyl you are cherry picking the one tragedy from an industry with an otherwise good safety record. The stakes sre high with nuclear as a single incident has dire consequences but you must balance that against the fact that incidents are rare. What your doing statistically is the same as claiming planes are dangerous because one crash kills so many people.

          Aug 28 2013: If you're tracking individuals you are doing case studies not statistical analysis. Case studies are of less scientific use as there are too many variables that cannot be controlled. That's why we do large study statistical analyses.
          They are tracking the radiation from Fukushima. You just do a survey of the background radiation in the pacific and observe any variations from the expected readings or you could monitor the radiation in a particular species of fish and track the progress of contaminated water that way.

    • Aug 24 2013: Actually, Fukushima was badly engineered. It wasn't obvious until after the fact (mostly because no one was looking for problems too hard--after the fact examination shows the signs and even a warning or two were all there), but in retrospect, it had some serious design flaws, like the emergency generators being vulnerable to flooding.
      Reactor design has come a long way since the 60's however.

      Realistically though, I don't see most of the world adopting nuclear. Its an easy target for fear mongering politicians and the media, environmentalists hate it, and perhaps most importantly once the Fukushima scare had died down, it requires a very significant initial investment to construct.
      Not to mention all those countries not allowed nuclear power because of politics.

      This basically means that we're stuck with fossil fuels and renewables. Renewables are impractical aside from a few niche roles, so we better not run out of fossil fuels anytime soon.
      Maybe some new technological development will change everything in a few years, but you can't count on those to come to your rescue at your convenience.

        • Aug 25 2013: Hah, I wish. If you know where I can contact them though, I'd love to get paid for going on random forums and arguing with people. Sure beats some of the other jobs I've had.
          Never mind that I'm backing nuclear as much as fossil fuel... They must both have me on payroll then. Apparently, I'm making more money then I knew.

          Seriously though, its not about land. It never was about land--most countries have more useless land than they know what to do with, no one's trying to save it for anything, not should using it be a priority.
          Saying we should switch to solar because we have useless land is like saying that I have a spare tire, so I should buy a car to install it in.

          Same for the side of buildings. Covering a house with solar panels dramatically increases the house's cost, and takes a few good years to pay for itself. Add to that decreased solar output the farther away you are from the equator, and you're basically throwing money at an unproductive project.
          Seeing as you need for everyone to have electricity on cloudy days, you still need all the non-solar infrastructure in place anyway, so you've basically installed twice the infrastructure.
          Solar is good for heating bath water, not for making electricity. If you want to install a solar panel, I'm not stopping you, but don't except me to throw my good oil/nuclear spokesperson money at the problem--there are better solutions.

          Its purely about cost per unit of energy.
          If the price of energy goes up, the price of everything goes up, and everyone's quality of life deteriorates. Never mind all those the other things the money could have been used for: infrastructure, healthcare, defense, education...

    Aug 22 2013: Just a note to US citizens. In the US fossil fuals aren't subsidised to make them cheaper than renewables. they are subsidised to make US fossil fuel competative against imported fossil fuels.

  • Aug 22 2013: I think many scientists feel that 350 ppm of CO2 in the atmosphere is the line over which we will hit a tipping point in the acidity and health of the ocean. (We just passed 400 ppm).


    As for temperature we are very close to the scariest tipping point which is where methane hydrates begin to bubble up out of the ocean. Once that happens the Earth as a viable place to live for man is over, at least for a short term, perhaps a million or so years.

      Aug 20 2013: and of course you got your numbers from some green website. not financed by wind and solar, so i'm told.
      • Sep 1 2013: for a measly $25 billion:
        Thank you for alerting me that some people believe that renewables do not compete with oil. They think that an electric car plugged into a house powered by sol/wnd somehow uses gasoline. Also, I didn’t get my numbers from a ‘green website.’ I started with 3rd grade math and the retail price of solar panels. I’ll show my math with some big round easy numbers.
        In the U.S., it costs $15,000 to solarize 1 house (labor, Inverter, & panels). If we solarized 10 million houses (that’s over 10% of U.S. houses, think of all those jobs), that would cost ($15,000 X 10,000,000 = $150,000,000,000) $150 billion. The govt. could pay for it all, but lets just offer a half-off rebate to the public and make it a 3 year project ($150B ÷ 2 = 75B, then 75B ÷ 3). That would bring the cost to the govt. down to a measly $25 billion per year, bad game over, good game starts. For the first time ever (fossil fuel) power plant usage would begin to decline, oil prices would plummet. So, America could say to the world and to itself, we are going forward, we are not self-destructing.
        • thumb
          Sep 1 2013: two observations.

          1. you did not even attempt to back up your original claim, namely that solar is cheaper than oil.

          2. government paying something means people paying. government only redistributes, does not create. if something is economically viable, we don't need the government. people choose it for their own good. we need the government in cases when we want to push something that is not economical.
    • Aug 21 2013: Actually, wind and solar aren't competing with oil, they're competing with coal, gas, and nuclear.
      Oil's high demand as a motor fuel makes it far too expensive for electric generation, to a point that even some oil producing nations export the stuff and use the money to buy coal or gas instead.

      Coal and gas typically come from stable countries, no need to "steal" them from anyone.

      Never mind that wind and solar are both completely uneconomical. 20 times more expensive than coal or gas is a best case scenario.
      • thumb
        Aug 22 2013: Maybe 20 times more expensive to install.... then the only time you have to spend money is to upgrade them to more efficient models. I think that would beat spending money everyday to get fossil fuels, not to mention all the labor and equipment costs for the coal mines, oil wells, power plants and their power lines, pollution, ect. The change would be a nice little shot to the wallet today but it's like renting VS buying. Spend more at once to save in the long run.
        • Aug 22 2013: http://www.oecd-nea.org/ndd/reports/2012/system-effects-exec-sum.pdf

          Not install, but fully operate at a power grid level.

          Renewable doesn't require any fuel, true, but you still pay for maintenance and staffing, and have a lower power output to show for it, which leads to higher operating costs per unit of power. 20 times more expensive than fossil fuels is a best case scenario for on shore wind. Off shore wind is typically worse, due to increased maintenance costs at sea and greater power transmission distance. Solar is the worst of the lot even close to the equator, and only gets worse the farther you get from it.

          Also note that having mother nature in charge of the on/off switch is economically problematic, as you need a reserve to supply power needs in case the wind is slow or sky overcast (or just generally after sun down for solar).
          As electricity storage technology as of today is rather poor (read: impractical on a mass scale), this creates all sorts of added technical problems, and increases cost overall.

          Initial investment for installation is typically only an issue for nuclear, which is more sophisticated than the other technologies. At least fuel costs are negligible, as Uranium is dirt cheap for the amount of power it produces.

        • Aug 22 2013: 1. I'll concede that coal is filthy, but gas doesn't pollute the environment with anything other than CO2 and water vapor.

          2. the figure actually comes from an assessment of OECD countries, many of which don't subsidize fossil fuels. Granted, cleanups were not factored in, but again, that's only really an issue with coal.

          3. good luck using solar or wind to replace oil. As bad as they are for electric generation, they're even worse for mobile applications--a car or aircraft can't run on sunlight or wind, after all.
          You could try to make a switch over to electric cars I suppose, but batteries have an atrocious power to weight ratio. It barely scrapes by for cars, and is laughable for aircraft.
          New capacitor technology might solve that, but as with all these yet undeveloped technologies, don't count your chickens before they hatch.

          Aug 18 2013: i don't want to force them. i don't want them to care. i don't want my lawnmower to care about the grass or the noise. i don't want my knife to care about the vegetables, meats or my finger. i don't want corporations to care about anything other than delivering the product or service they are created for. i want the consumer to care. i want people to care.

          that is the biggest problem we have. people don't care, but that's OK, because they blame it on someone else. they happily buy fish, and at the same time blame companies for overfishing, or governments for not regulating or badly regulating. all they have to do is not to buy wild fish, problem solved. but of course that won't happen. blaming someone else is so much easier, and we all love wild fish.

    Large-scale solar (Gemasolar):

    Nuclear fusion (nearing feasibility):

    Energy that costs little, is sustainable, or is incapable of raking in vast profits for huge corporations, will forever be of minor importance as long as capitalism remains the pervading ideology.

    Sucking or hewing stuff out of the ground translates as a product that can be bought and sold. Anything remotely sustainable does not. That's the bottom line.

    I'm afraid capitalism has to run its own course of blindness, denial and stupidity before it sees any need for change. When there's no more easy money to be made, it will disappear up its own fundamental orifice, taking all its filth and pollution with it. What a blessed relief that will be for everything that lives - though I doubt I'll be around to celebrate such a long-awaited spectacle.

        Aug 18 2013: I'm actually filled with guilt that my generation has comprehensively messed this world up for your generation. You will have to rebuild what we've destroyed, leaving you with no natural resources to use sensibly and sustainably. I don't feel great about that.

        The point being that many individuals may possess the conscience to feel aggrieved enough to do something about the harm that collective "others" are doing, but remain powerless to put things right. That powerlessness exists because the normal channels of complaint and protest seem now to be closed off - or at best, remain open, but with nobody listening - such is the power of the ideologies you and others are up against.

        When even scientific research gets grotesquely distorted in order to support highly funded ideologies or products, you know that something is going very,very wrong indeed and the lunatics have taken over the asylum.

        In the face of such powerlessness, some resort to wholly unacceptable violent protest, which makes matters significantly worse for everybody and only ends up in some form of despotism.

        What's left then? Unless there's the unlikely occurrence of a global change in consciousness, the only option is to wait it out.

          Aug 18 2013: Your generation has taught us that the earth is fragile and we do have an effect that is very noticeable after only one generation of heavily relying on fossil fuels. You are not responsible for what your whole generation has allowed to happen either. It isn't like anyone knew the effects that fossil fuels would have when the industrial revolution started. Now that we do know, it is time to do something about it. I agree that there is something majorly wrong when studies are distorted so people can keep making money off unsustainable, ecosystem destroying fossil fuels. I know the transition is going to be difficult but we have done plenty of difficult things throughout history. I agree that the violent method is not the best method and it is one I would not support or condone. I do believe that the global consciousness can change if the real data is known by everyone. Some people are still in disbelief of the facts. We could implement alternative power now and destroy the fossil fuel tyrants. The real challenge is going to get people to see the facts and be able to decipher the propaganda from the real data. Even my generation is still addicted to fossil fuels but some of us are aware of the truth. If it is not my generation that achieves this, I hope the next generation will. For now, all we can do is inform people about the facts. From then on, it is their decision to make for their future.
        • Aug 22 2013: Stop with the guilt and stop believing the outright lies. Anyone who claims that a single generation has gotten us into the current situation regarding fossil fuels is either an idiot or a liar. What year did fossil fuels start making up the majority of US energy production? Go ahead, take a guess.

          The year was 1885. That's right. 1885. From that point on, "heavily relied upon" fossil fuels would be true to the present day.

          Think about that.
          Now, since I live in the real world and not some play-pretend cartoon carebearland, I don't consider 1885 to the present day to be a mere single generation.

          The "Industrial Revolution" started about 100 years earlier than the fossil fuel event.

          Going around blaming a single generation is simply nonsense. This has been building for over two centuries. However, since nobody bothered to notice until recently, stupid people believe that it only started recently.

The current schedule to close all coal fired power plants that is being hotly pursued is a plan for national grid failure. Nuclear power is being regulated to death. The fifty plants in design are down to two.

    This is the time for serious people to make rational sane long range decisions .... not the time for politicians to seek votes. To continue on this path is a sure fire means of destroying the current grid system and reducing the available power and driving companies out of business with no means of recovery.

There is always a financial setback even thought running things with these types of power would save money and pay for themselves eventually. The savings from not buying oil and the free energy would be a stimulation to our economy and what can come from that is endless.

Don't you know those big bad businesses also spend millions even billions developing cleaner ways to burn fuel and alternative fuel technologies?
  • Sep 9 2013: The cost of ANYTHING is a direct measure of the resources that must go into producing it. If renewable resources are more expensive than nonrenewable then that means they probably take more out of the environment than nonrenewable. As a result, they may cause more pollution not less. This is true of Ethanol for example. It takes more fossil fuel to produce Ethanol in the current manner than it does to just use the fuel directly.

    One must also realize that, even with current cheap fossil fuels, most people in the world spend a very large portion of their income on food. I've heard that many spend as much as 90% of their money on food. If we do not bring down the cost of renewables to at least match fossil fuels then there will be a lot more hungry people out there. Hungry people are violent people. Just look at Egypt, LIbya, and Syria, it is the cost of food that has lead to their recent troubles.

    Sep 5 2013: I have to say this whole "we dont have the capital/money to do this" is BS. A company that makes solar panels could steal a page from the banks playbook and lease/loan the solar panels and get monthly payments on them. Pollution will decrease. Natural resources could be used for other things that renewable energy can't be used for. Yeah solar panels are expensive and yeah they want to make a bunch of money. Well understand this, if you're dead you can't make any money. We say we're smart but it seems greed is overriding all that.
    • Sep 5 2013: Its not about "we don't have the money". Its about "we have better use for that money".

      Its not that we can't find funding. If we slash enough budgets for other things, and take enough loans, we can start making a transition to 100% green energy tomorrow, and probably be done in a few years.
      It would crash the economy and lead to all sorts of different damages though.

      Saving money isn't about greed, its about resource allocation.
      What money we're saving on energy by using cheaper fossil fuels we can spend on things like healthcare, infrastructure, defense or education.
      I don't care what country you live in, I'm sure some of the above are in need of improvement. Sometimes even desperate need.

      Take into account the cost of energy affecting anything and everything, and cheaper energy directly translates into a higher standard of living for the lot of the populace.
      In that regard, the expensive solution of going green would be shooting ourselves in the foot. Its really bad for the economy, and whats bad for the economy is bad for the people, not just the top 1%.
      • thumb
        Sep 9 2013: To tell you the truth, I don't think it would be bad for the economy. For one we would have more money to spend throughout our economy instead of making a few select people rich beyond belief. For the resource allocation I'd have to say this isn't checkers, it's chess. We could spend money now on American-made (seeing as I'm American) Renewable Energy. The workers are American so they spend money in America, not to mention people would buy houses, cars, ect. There's most of the cost right back into our economy. I know this is optimistic but shouldn't we be? This is all without mentioning our Defense budget.


        From The Washington Post
        "All told, the U.S. government spent about $718 billion on defense and international security assistance in 2011 — more than it spent on Medicare. That includes all of the Pentagon’s underlying costs as well as the price tag for the wars in Iraq and Afghanistan, which came to $159 billion in 2011. It also includes arms transfers to foreign governments.
        (Note that this figure does not, however, include benefits for veterans, which came to $127 billion in 2011, or about 3.5 percent of the federal budget. If you count those benefits as “defense spending,” then the number goes up significantly.)
        U.S. defense spending is expected to have risen in 2012, to about $729 billion, and then is set to fall in 2013 to $716 billion, as spending caps start kicking in."

        That is a SUBSTANTIAL amount of money and to consider the veterans and their families that end up receiving benefits, not that they shouldn't. Less soldiers and weapons means less spent on benefits and less violence, all while we invest in renewable energy to lower our need for fossil fuels. As I said before it's very optimistic but it is not impossible.

        Thanks for the reply Nadav. The input is most certainly appreciated!
        • Sep 9 2013: I very much doubt that going green would redistribute the wealth.
          Instead of oil tycoons, you get wind farm tycoons. Wealth disparity isn't a result of the fossil fuel industry, its a result of capitalism. The current system is built to encourage that sort of thing, with a list of advantages, and a list of disadvantages.
          A renewable switch makes the cost of living go up, and everyone poorer, rich and poor alike (though the poor, as always, feel it more).

          This is also true for countries as a whole. Developing nations are hurt much more by a renewable switch than developed ones.

          I'm also not sure just how much it'll help the local economies. Parts are usually made where its cheapest to make them--the moment that's foreign, they start importing them. You could insist to keep them domestic, but that further pushes costs. The workers usually have to be local, but the workers at coal and gas plants are also perfectly local.
          While stimulating the local economy through government spending on rebuilding the energy grid has its benefits, it also further alleviates the problem of government debts (already bad enough in the US).

          Finally, your arguments for slashing the US defense budgets, while sound, have nothing to do with renewable energy.
          It has to do with over spending. Related in a way, but not inherently connected.
    • Sep 5 2013: They already do that. In our State you can get the power company to install your solar panels on the roof, no charge. Then you pay a monthly fee for the installation and also get the credit for the electricity generated. In many or even most cases the result is your electric bill decreases.

      The electric company gets several benefits. They get electricity at peak hours. This is critical because their grid has to be designed to handle peak loads.

      Second, they don't have to build additional transmission lines to handle this extra capacity. That is a very significant savings.

      Third, they don't have the issue of public hearings and all the other hassle in getting extra power generating capacity built.

      Fourth, laws restrict and penalize pollution from coal plants. The greater the percent of power generation from clean energy the better the power company does with health and environmental regulations.

      Fifth, there are tax benefits, City, State and Federal, because they understand the savings in health related issues, the jobs that are created locally, and the tax benefits of having real improvements made to real estate.

      Sep 2 2013: i would suggest that "mr reynolds" is just the next reincarnation of our angry ghost, and should be removed. i would mark his profile ... if he had one.
  • Sep 1 2013: In 1982, in my college physics lab in Portland, Oregon, we calculated the costs of nuclear versus solar power. We determined then that the cost of the solar panels was cheaper than the cost of nuclear to supply power for an equivalent number of homes. This did not include the cost of installing the panels or the storage medium, ie batteries and inverters. Now, this was in Portland, and we took the weather into consideration. Plus it was 1982, and the cost of solar cells has come down considerably since then. (If I remember correctly, at that time the cost per home was about $30,000.)
    The real reasons for absence of alternative energies are profits and control. Oil is profitable. Nuclear, and other centralized plants, keep us tied down to a community and remove a certain degree of our freedom and autonomy.
    Tesla had plans for a central broadcasting station for electricity in the 1920's, and would have sent it out freely, without wires, all over the earth. This was shut down due to the inability to make money off his system. Now, it was never tested, and may have been a disaster if used, but the principle remains: we do not have alternative power today because those who control the world's economies can not make money off of it.
    • thumb
      Sep 1 2013: your calculation was probably incorrect. what usually happens is that people include all the legal and administrative costs of building and operating a nuclear plant, exclude a lot of real costs from solar, and include subsidies to solar. this suspicion of mine is supported by the fact that you admit leaving out storage for solar, and probably also any sort of grid costs too.
    • Sep 1 2013: For a start, I tend to agree that something in the calculation was off. As I don't have it in front of me, it'd be hard to guess exactly what was the issue with it.

      Second, even if the calculation was spot on, the market has shifted quite a bit since 1982.

      Third, the problem with renewables isn't profit, because there is money to be made. The problem is that there is less money to be made than fossil fuels or even nuclear--higher expenses, lower power output, and lacking control over the on-off switch all hurt quite a bit.

      Also, a note on Nicola Tesla. While I am in no way disputing that he is very much the man who "invented the modern world", you must remember that later in life, his funding having gone dry, and worn down by years of competition with Edison, Tesla had a tenancy to make all sorts of wild claims to keep in the public eye.
      What Tesla published in detail all worked brilliantly. What he left purposefully obscure (like the death ray, earthquake machine, and using the earth as a power grid), he did because it was nothing more than a tall tale.

      Sep 1 2013: Phillip,
      Your class made the same mistakes that too many do. It was based more on a political theory then the basic economic issues.
      I will use my house and numbers I had when considering solar panels.
      First: our local power company bought power from individuals at the wholesale rate and sold it back at the retail rate a spread of $.04 per KW.
      Second: Initial installation of 4 KW of panels on my house would be $22K with a estimated life of 15 years.
      The sustainment cost including depreciation was estimated at $1400 pa. The ROI was flat, mostly because we go north for the summer and shutdown the house.
      Third. You used houses in your calculations. Houses simplify calculation. Commercial power is not just about houses. It's about factories, shopping centers, airports, office buildings, hotels, amusement parks, medical centers. Power requirements are all over the place.
      Forth: Yes, commercial power companies make profits. How could you have a business without profits?
      Even publicly owned power companies make profits. Now, if you are under some belief that profits are bad,
      we need another whole conversation.
      • thumb
        Sep 1 2013: it is time for us to reconsider our thinking about profit. i don't know what is the exact origin of the sentiment that profits would be bad or irresponsible. maybe marxism, maybe paternalism, maybe escapism, i don't know. but people have to understand how profit works.

        it is not that hard. whatever i do, i take some resources, like raw materials, energy and manpower, and i use those resources to produce something. that something is the "product". but since i used up resources, i also prevented some other things from being produced. if i make chairs, the wood i used will not become tables, pencils, paper or electricity. we call these goods foregone "cost". profit is nothing more than the difference between the goods produced and the goods foregone.

        using that framework, "profit" really means nothing else than taking resources, and transforming them into something that people want more than anything else that could have been produced from the same resources. and "loss" means i took some resources, and transformed them into something that is less wanted than something else that could have been created from the same resources. i made chairs, but people wanted cupboards.

        profit is efficiency. loss is waste.

        it seems to be easy and straightforward. but unfortunately we need much more effort to make people understand this.
        • thumb
          Sep 1 2013: I look at profit in the capitalistic manner. Profit is the return on application of time, materials, labor and equipment. Sometimes there is no profit. Sometimes some will say there is too much profit. There are market forces that control profit outside the the hands of the maker.
          I believe we are due for a spirited conversation on profits amd what value they present to society..
      • thumb
        Sep 2 2013: we are talking about the same here. money cost is the apparent cost. but one has to look further, what is money cost? money cost comes from the best alternative use of the same resources. thus, if you make a profit, it means that you create more value than the alternative. if you make a loss, the alternative would have been better, and you wasted resources.

        Sep 2 2013: And I am hearing just the opposite. A company here in Texas has developed a smalll self contained nuclear generator based on what is used in ships and is contracting to install those in a number of places. New large plants have not been built because of a myriade of suits and regulations, etc; Old plants are being closed do to be worn out. Uranium is the third most prevalient energy source in the US behind coal and oil.
        My take seems to be different then yours. I think nuclear power is a viable option and should not be regarded as useless.
        • Sep 2 2013: To Mike Colera:

          I only brought up Israel as an example to point out nuclear reactors aren't terrorist targets. I can't actually bring up how competitive it is for power generation, because we don't use nuclear for power generation here. I know of two reactors in Israel, one for research, the other for production of weapons grade material (unofficially of course, but everybody knows--its been called the worst kept secret in the middle east). Terrorism though, we have plenty of, and no attacks on nuclear targets to date, too hardened.

          We're one of those parts of the world were you can't touch nuclear due to politics--looks too much like a weapons program we don't officially have.

          This is actually a big problem for nuclear in the developing world.
          A weapons program looks very different from a peaceful one when examined closely, but not from a distance, and people often don't care to try and spot the differences. Many countries risk international sanction or even military action by perusing a peaceful nuclear program.

          Not to mention the lack of technical know-how. Hiring foreigners to do all the work, and importing half the components for the project is as politically problematic as it is expensive.

          I'm afraid nuclear is simply out of reach for much of the world. Combined with the high expense per power output of renewables, and you see why the developing world would be shooting itself in the foot trying to reduce emissions.

          Honestly, it global warming is real (which I doubt), we may well be better off spending money on damage control than on trying to stop the inevitable, because I don't see the planet going green any time soon.
      • thumb
        Sep 2 2013: nuclear being expensive is a recent development, it wasn't always the case. those expenses you have listed are of course included in the operational costs, and not hidden. the costs that makes nuclear expensive are due to the heavy overregulation (and let me add, ineffective regulation). all the extra cost this regulation puts on nuclear constitutes up to 2/3 of the total cost.
      • Sep 2 2013: Those foreign Uranium sources you're talking about are places like Russia, Canada and Australia. Unlike with oil producing nations, these are typically stable countries, that can be counted on not to make a fuss.
        Same goes for coal and gas. Its only oil that's politically problematic, and renewables can't do a thing to replace oil (they're useless for mobile power generation--which is where most of the oil is used).

        Avoiding any foreign energy sources is essentially shooting yourself in the foot. The US simply cannot support its own energy needs using only domestic fuel sources--unless you want to go entirely renewable, in which case, good luck having your industry compete with exorbitantly expensive electricity prices driving production costs high.

        Nuclear material is actually widely available, and fairly cheap to boot. Its the enrichment process that's costly--it takes a specialized and rather expensive infrastructure, which is why nuclear proliferation has been as slow as it had.
        Reactor grade material and weapons grade material are not quite the same thing either. The weapons grade stuff takes a much greater level of enrichment, and is practically never sold.

        Nuclear's biggest problem at the moment is the construction of new nuclear plants being made artificially slow and expensive by a combination of over-regulation and local politicians smelling an easy target.
        Once a plant is up and running, its quite economical. Not as much as fossil fuels perhaps, but still a fair bit better than renewables.
      • Sep 2 2013: http://www.oecd-nea.org/ndd/reports/2012/system-effects-exec-sum.pdf

        On a strict, kilowatt-hour per dollar basis, nuclear is cheaper than onshore wind by a factor of between 4 and 8, depending on the country. It only gets worse when you move your wind offshore or start using solar.
        Nuclear is more expensive to set up, true, but once its up and running, its is without a doubt cheaper.
        For comparison, fossil fuels are typically around 5 times cheaper than nuclear.

        Being a target for terror attack is also not much of an issue. Its pretty easy to build a containment structure that can resist improvised rocket attack (which you'll need for any nuclear plant anyway), and a dozen military grade security guards can stop any ground bound terror attack just fine. Populations centers will always be more enticing targets, as they're much larger and therefore impossible to defend so easily.
        Case in point, Israel, where I happen to live. We've had well over a thousand successful terror attacks targeted against us in the past two decades, and despite this, not a one was targeted against one of the country's nuclear reactors. They're just too hardened to be enticing as targets.

        As for regulation, the problem is with the process is that in the US, most of the regulation isn't actually productive, but in practice does nothing but artificially increase the cost of construction for a nuclear reactor. Think of it as bureaucratic roadblocks set up alongside the legitimate stuff.

        As for no one wanting to live next to a reactor, just set them up away from population centers. You'll take a hit on grid costs due to the plant being far away, but if that's what it takes, that's what it takes. Disposal sites can be as remote as you like with only a negligible increase in expenses, so they're not an issue.

        And if the US wants to be truly energy independent, without importing a thing, it'll sign the death warrant of what industry hasn't already moved to China. It'll make it non-competitive.

          Sep 2 2013: I live in the 7th largest metropolitan area in the US. Different parts of the world have differing issues. In the broadest general terms, Australia has almost no population density. Israel (with all due respect) is a sardine can. USA is not really all that crowded.
          Our local major power supplier uses energy from all the resources. The integration is carefully planned to make best use at the lowest possible cost to customers. One of the largest solar "farms" in America provides peak power support during the hottest days, Wind power is brought on line as available for maintenance time and repairs. Old inefficient plants are being replaced with new fossil fuel plants to meet air quality guidelines. And for those who are critical of money hungry usurpers, this system is publicly owned.
          Each nation has to provide their citizens with the best model available.
          Having said this, one thing learned here is that the "renewable are not controllable. the best that can be foreseen in spite of claims to the contrary is an 80/20 ratio of controlled power.
          Now, if you go off line to provide your own power, you must be careful. My provider must provide power to my residence. If I am off line, I am on my own and failure can be catastrophic.

          PS. Here the retail cost of wind is $ 0.14 pkwh and nuclear is $0.10.8 pkwh. It is different in different places. Our retail cost to residential customers is #0.11.1 pkwh. My average cost for my totally electric home is $120 per month

        Sep 1 2013: i consider the conversation dead. the new rules of the game: who can ridicule pseudonym caesar ducant more? would there be real moderation on these forums, and would the moderators understand the threats to a genuine discussion, the problem could be solved. as of now, we need to deal with a google troll, and it is either you leave, or you play his game, or you try to upset him the best you can as a source of fun. discussion is not possible.

          Sep 1 2013: Aja posted a couple of weeks ago that Conversations were on vacation until September 2 or 3 in the sense that moderators were mostly on vacation.

          It appears our moderators have now returned.
  • Aug 31 2013: one reason is that people think we need newer high tech solutions. we could take all our existing internal combustion engines, all of our cars and our generators, and run them off of alcohol or methane with little to no alterations necessary. that is an energy source which is 100%green and clean, completely renewable and very easy to manufacture which means no big business can own or control it. and because internal combustion engines are already what we are set up for, it could be done immediately. very low tech, very simple, very inexpensive, very effective. can be implemented immediately across the board. the only reason it isn't being done is because people aren't thinking it. change that and you change the world.

    Aug 31 2013: Mr Kable,
    Your question has resulted in a tirade that has proven non conversational. To address your question. two points based on my experiences and knowledge is as follows.
    1. Hydro power is not really available to any extent in the USA. Other countries are expanding this method of energy production. Alternatives such as solar and wind are useful additions to any power system, the one flaw with these resources is that they are not controllable Energy providers have to have the means to open and close known and reliable energy flow into the grids. In my area, solar energy is used to make up peak period demand during high use such as air conditioners when the temps reach 100. Good use. Wind power is used in the grid when available to lower fuel use in generator plants. Good use. But the use of power is ever increasing and current systems are under stress. Alternative energy systems can help, but can not replace conventional and controllable power resources That is a fact for the foreseeable future.
    About mother earth. Yes, something is going on. Some claim it's is industrial pollution that is causing these changes.
    Others are not so sure. The problem is that earth has been undergoing constant changes albeit so slow that sometimes we can't even se the changes coming. So is industrial .pollution causing the tipping point?
    Could be
    If man can stop all industrial pollution, will the climate settle back to it's old position?
    No one knows and no one will guarantee. The best guess is it won't get any worse by some and others say that earth climate is already shifting.
    What bothers me about all this is the passion that this debate has taken. Science is a very matter of fact. No emotion. Yet, we hear that millions of people will die due to raising seas and all the polar bears are doomed to extinction. These things may someday happen... The oceans have been up and down. 95% of all life on earth has gone extinct. We need is careful analysis not panic
  • Aug 30 2013: Guys, the administration won’t invest in something that is less profitable for them.
    Here in South Africa I here we got too much of natural Gas, but guess what Government will rather sell it to outside inventers. Secondly we pay too much for petrol (Gas) and yet our neighbouring countries they pay less for same service and yet they buy it from us, tell me what’s that?
    Any method that will make our life at easy is contradicting with what states and administration stand for they are here to make money and now you want to turn around and invent or expose what I will call free lunch no way!!!!

    not yet finish to be continued, Im rushing off

      Aug 30 2013: in fact you googled them, or just picked some from forums, and posted without looking into them. we need a new term for that. i proposed "google trolling"

        Aug 30 2013: I like the term "google trolling". It seems to fit so well. I mean the internet is completely free of information that is bias, skewed, out right untrue or self serving, isn't it?

        What is the term for those who read up to 2000 characters in a comment and finds fault with a dangling participle? Compulsive Context Focal Disorder?

        And then there are those that take a conversation subject and address an entirely different matter that has little to do with the comments at hand....

        Whoops, I may have been guilty of that one

          Aug 31 2013: in the previous post, you originally wrote "vitamin K potassium is not cesium". you have edited your post to look less silly, but still contain reference to vitamin K so it does not look edited. you do this in order to hide that you don't know the difference between potassium (chemical symbol K) and vitamin K. i would say that here goes your credibility, but no, you did not have credibility to begin with.

          obviously, you do not have a degree in health, such a blatant mistake would never be made by anyone ever learning about the human body in any way.

          Aug 31 2013: it was an exact quote, which is further supported by the fact that you left the vitamin K part in, which would be otherwise be totally unrelated. i expect now that you edit that out too. i wonder if there are rules on TED forums against heavily editing comments.

          Aug 31 2013: keep quoting, as you keep editing. this time it is

          "... potassium with Vitamin K since they are both K in the periodic table"

          vitamin K in the periodic table?

          Aug 31 2013: because it is. both K40 and Cs137 are beta emitters, and they emit approximately the same energy electron. actually, K40 emits higher energy. both of them are members of the first group of the periodic table, and behave alike. and to those that curious, potassium has a natural 4000-5000 bq radiation in a human body. this amount does exactly nothing. to be any dangerous, we need mega- or gigabecquerels of radiation.

          so where do we find vitamin K in the periodic table? have you edited your post already? lemme check... no, it is still there. unlike your remark about "vitamin K potassium".

    • Aug 30 2013: So let me get this straight, anyone who isn't persuaded by your arguments is automatically assumed to be on payroll by a corporation whose interests don't match your own?

      That's convenient. Your arguments must truly be infallible then, for everyone to be so easily swayed by your logic except those paid to pretend otherwise.

      If only persuading people was so simple for the rest of us mortals...
      Or if a corporation was actually paying me for posting on random forums; I could use the money. Perhaps you could do me a favor and use your great skills of persuasion to talk one into putting me on payroll?

          Aug 30 2013: have you researched becquerel? you were talking about like 15000 or so bq cesium in fish. tell me what is the normal level of radiation in bq in an average human body coming from potassium. can you google that too?
        • Aug 31 2013: Legitimate reasons? Sure, its expensive as hell.
          As the price of energy affects anything and everything, expensive energy means expensive everything, and the quality of everyone's lives goes down.

          I've posted a link bellow of a study in OECD countries proving that fossil fuels and even nuclear are all cheaper than any of the renewable alternatives on a kilowatt per dollar basis. Natural gas and coal are usually between 20 to 40 times cheaper than the best case renewable (onshore wind).
          Granted I'm not factoring in air pollution (only really an issue for coal) or set up costs (expensive for nuclear, cheap for fossil fuels), but all in all, fossil fuels still come out a lot cheaper, especially natural gas.

          Look, I'm not saying that new developments in renewable won't change that, as they might, but one simply can't place their trust in as yet uninvented technology to come solve all our problems for us. When its here, I'll believe it, until then, I'm sticking to what I know works.

          That's for developed countries.
          In developing ones, the higher expenses usually mean that using renewable means more people who don't have power period, never mind that you need cheap energy to set up any real sort of industry.
          Remember, most electric consumption isn't by the average user, its by industrial processes. Cost and competitiveness are a very real issue--otherwise, they just move their operations to some other country with cheaper energy bills (or lower taxes, whichever saves them more money).

          Just because people all over the world are adopting renewables doesn't mean its a good solution. Appeal to popularity is a logical fallacy.
          Besides, while I don't have the numbers on hand, if you look you'll find that there is plenty of investment it fossil fuels and nuclear as well--apparently some people at least agree with me.

        I believe that anyone who is so focused on their points to pretty much ignore reading the complete comments and further hide in some unanimity is not worth discussion. In several of my comments I wrote that there is a place for some alternative power sources, I cited my local company who has managed to use a variety sources to provide power at the best possible price to their customers. Which is what commercial enterprises do. Fanaticism is not a basis for discussion.
