I heard some really disheartening news regarding recent studies of ethanol. According to some scientists, the net energy cost of ethanol production is considerably lower than the yield. Meaning that it may be completely unviable as an alternative to oil.

Sorry for the lack of details - I heard about it on All Things Considered on NPR. Maybe there's something on the website. Or you could always google "+ethanol +corn +net +yield" and find something, if so inclined.

The good news is that there were other scientists who disagreed with the findings.

In general, ethanol isn't really viable. Commercial agriculture in the US relies heavily on oil and oil resources, and therefore the net energy yeild is negative (more is consumed/utilized than produced).

However, there are ways of converting waste-oil into usable fuel, but again, that takes energy to make energy. Though, in this case, it's more productive.

With regards to solar energy, if people can see beyond the photovoltaic cells (which, admittedly, help but need to be developed more), there are ways of using solar energy productively.

all very good ideas, but I doubt current administration would take these into affect :/
