What makes you think many of us have not already done all those things?
The problem I have is with pie in the sky energy source throwaway statements.
All the suggestions would make someone rich beyond the dreams of avarice, and make hydrocarbon fuels a nightmare of the past, if only they were realistic.
Nuclear is a good example.
Yet nothing ever actually happens.
I commend you. Large sectors of the American populace still live in older, poorly insulated homes and use energy-profligate appliances. And we know about the popularity of SUVs, but that's changing. I drive a minivan, but it's frequently a multi-passenger vehicle, so I get good per-capita MPG.
I think there are tax credits available for energy conservation in certain ways. Expansion of a program like that would be a good incentive.
