Renewable sources currently provide only 16 percent of our energy in the U.S. and 11 percent of our electric power. Unless the production of these renewables can be increased substantially in the next 50 years and the efficiency with which we use energy increased many fold, then the world is going to become a very dark and stagnant place.
There is running debate going on between people who believe all is lost without copious supplies of fossil fuels to power the global civilization and those who believe that the conservation and efficiency that will come with very high fossil fuel prices will provide a recognizable future for civilization. The great unknowns in all this is whether there will be sufficient financial and other resources available to effect the transition and whether or not the damage wrought by a changing climate will be so serious that a global transition to renewable energy will be difficult if not impossible.
For the immediate future, however, much of what life in the future will be like will depend on the technologies that will enable civilization to continue while using only a fraction of the energy that is consumed today and to develop the technology to produce large quantities of cheaper renewable fuels. The manner in which our fossil fuels are being used is so wasteful of the energy contained in fossil fuels that major reductions can be made with little real impact on the activities that consume energy. The prime examples of this waste is the internal combustion engine which uses only 14 percent of its fuel to turn the wheels while wasting most of the rest. Huge central power plants waste most of the energy that devours coal and natural gas, and produce much waste heat that is dumped into the air or local water bodies or in line losses. Without the massive waste, the fossil fuel age could last a lot longer. More >>>
