I am a sceptical about these alternate sources of energy. We might have a situation here where neither electrical cars, nor ethanol, nor hydrogen will ever come even close to the convenience of oil as a portable, storeable, efficient and cheap energy source. As with all science/engineering, we just don’t know if we are ten or two hundred years away from a workable replacement. The fact that we all *want* that replacement to be found has no bearing on the fact it might not be easy or even possible.
Similar to looking for a flu vaccine. Enough people are looking, and there is *much* money to be made there but the problem itself is not easy.
I certainly hope I am wrong. I also do realize my point of view is not helpful or does not give people warm fuzzies but that’s the way I see it now.
Buy oil, they ain’t making more of it.
