Ethanol has always been a farm subsidy program. We are just trading ADM for Exxon.
The only long term answer is nuclear with some wind and solar in places where it makes sense. Solar is efficient when you are just using the heat in a very low tech way. Heating water is a good example. I am in a building project that required me to take down my solar pool panels. I immediately lost 6-7 degrees from an uncovered pool. Fortunately it is warm enough so I can still swim but my wife is waiting for July.
The next generation of my solars will also heat my spa and preheat water going to the domestic water heater. That is a real saving $$$.
