Hydrogen would be a viable alternative. Electricity can be generated by coal fired, or nuclear, or wind farms or hydro power plants. 2 of these forms are renewable. Coal is not but there is a huge abundance of it and does not burn more fuel to produce it than the energy it creates. Also we should build more coal gasification plants. I just do not see burning up our food sources in our gas tanks. It is great that farmers are getting a good price for their comodities, But (and I know this will get me hammered bad) the government will always be there for them, as the government knows how important the farmer is to the viability of this nation.
