They are using so many different types of plants corn,soy beans,sugarcane,algea which all depnd on water which is becoming a scarce comody in alot of this country.They just built an E 85 refinery not far from where I live.Im not sure whats being used to make the fuel but it sure isnt making any electricity only using it.We have enough strain on our power grid as it is.As for the our nations power grid the infrustructure of it is crumbling.Compared to other countries that have updated their power grids the US is far behind.I beleive the time is now so Im not left in the dark when it crumbles.
As far as power grids go. The US has one of the best in the world, so you might want to check into that before you say stuff like that.
