literally the least environmental choice right there based on how much electricity it takes to produce. Furthermore, due to current and expanding demand for electricity, even if you wanted to do some captain save a ho ocean tide to electric project, there will be better use of that electricity produced. There is only one reasonable way forward because one thing for sure the petroleum dance will stop at some point, and the answer is to grow your own fuel. The rare metals needed for solar production and storage of electricity also has a half life similar to petroleum reserves. We are already running out, who knows what will run out first these metals or ground oil? The future is corn fields my friend, or oil plants better known as Jatropha Curcas, as in grow your own diesel. There is no answer, even nuclear fuel is running out, yup it's true. 100 years from now, a blip in human history, every homestead will be figuring out how to grow their own gas or diesel. Anyone think otherwise, you have been listening way to much to merle haggard.
