Jun 26 2012: I don't know why we should talk about fuel efficiency while "the smartest barrel of oil is the one you don't use". Why don't we make every existing barrel the smartest one? is it impossible? I believe we will have to. We must cope with this addiction of fossil fuels. I always have the peak oil in mind. What are we going to do about that? Until when we will improve the fuel efficiency?
Jun 26 2012: This is may be the best short term solution, but when we will be 9 billion and after we reach the "peak oil" this won't work anymore. For one reason, whatever you do the oil won't be affordable anymore.. the production will simply decrease and the needs to energy will increase. I don't think Shell can do something about that except providing us with another source of energy. We can't evolve without doing that. We must stop using fossil fuel. Another solution is to use the green algae. there are many research done concerning the use of green algae as a fuel. The advantage is that we don't need to change the infrastructures and it's easy to produce.
Jun 25 2012: It might be a good solution. the nuclear energy is really efficient. But what about the safety? I think in case of a meltdown we are going to have a huge amount of radioactive waste that the future generation will inherit from us. So, how can we deal with that?
Jun 25 2012: We MUST use the other alternatives of fossil fuel, because they already exist. Fossil fuels have no future. Once we start investing on safe, cheap (or free) and reliable sources of energy, building one city every week will be a breeze. Let us imagine if we can use the full energy that comes from the sun every fraction of second just as an example. Fossil fuels have never will never be able to compete against the clean sources of energy from nature. Just in the Saint-Laurent estuary the company Hydro Quebec produces the equivalent of energy of all the oil produced by all the companies in Saudi Arabia. So, let us imagine again as well how much energy we can get from the ocean.. there are many ways to do that, where each one of these ways has advantages and disadvantages. Anyways, they are still much more reliable than using fossil fuels. The energy is overhead not downwards.. I find incomprehensible the fact that we waist energy by challenging the gravity and other forces to get dirty fossil fuels while we can get energy without doing that.
