Think back a couple of years, when corn was being touted as a "renewable energy source" and its plentiful supply would solve our energy problems forever. What happened?

1 Answer

Answer :

answer:Biofuels are a good idea in rich countries with surplus production of food. Biofuels are a bad idea in poor countries where people struggle to be able to pay for their food. Using arable land for biofuel makes food more expensive. Full-scale corn-as-fuel production in the US is not a full solution for the energy problem. The American Southwest should become a giant solar energy plant, mainly solar thermal, not photovoltaics. The Midwest could become a giant wind energy farm. And there’s also geothermal. Plus energy efficiency. Better windows. Better insulation of buildings.
