I'm not saying renewable energies are not competitive. I'm saying that behind every renewable energy is a HUGE capital investment. Although they are virtually free, they are not as great a business investment as they seem. Most people would rather invest in something that yields a higher profit than in a renewable energy.
But you have the same huge capital investment behind other power plants.
Eh, look at how much Brazil actually produces, if it wheren't for some stupid laws, they would be exporting a lot to the U.S. And while I agree that corn is a terrible choice, new kinds of crops are being designed, and it's not like it's impossible to import the stuff from places it's competetive.
