What will be the best renewable source of energy in 2050?

As of now, we have Wind, Water, Solar, Geothermal, and many more. But as our technology changes and diversifies, do you think we will use completely different sources?

    Jul 29 2012: I think it will (have to) be a simple system at the level of each household. Simple meaning mechanical rather than nuclear or chemical, because of the risk values. At the household level because we have to overcome the transport variables (miles of wire, transformers, whatever). As a hypothetical example, imagine something like a roulette wheel where the rim and the ring around it are magnetic opposites. With such a low-friction coefficient, a small input can sustain output creating an amplification. I don't know if this works, but look at how low the risk/repair costs for something like that would be.

      Jul 29 2012: We are on the same page Erik ( see my post to Debra Smith above). I realy feel that all renewable energy will be co-opted and monopolized by the plutonomy if we do not have a household controled site specif, lo tech lo cost solution available.

      As I am sure you have noticed, public policy onn renewable energy globally is being driven by the plutonomy ad certainnly not in the direction of household specific generation using lo tech equipment.

      That leave sit up to us, "we the people" of the world to find and make these household specific lo cost lo tech choices..if there is no one to but what he plutonomy is offering..and if we stay on our pols to include and provide strong incentives for household ( and community) specific energy generation independent of the grid.

      If on a per household basis in Maine the subsidy and electricity costs increases being given to wind power and thr grid to collect and distribute windpower were divied up every single person ad every single business in Maine could be off the grid and on endlessly renewable low cost lo tech energy.

      Household specific lo tech renewable energy will not get the subsidies and tax credits unless "we the people of the globe" demand that and make that choice for ourselves ahead of public policy.
