When we added onto our house last year one of our major investments was installing solar power. And I won't kid you, it was a major investment. One which we will not likely "break even" on until our kids are in college. But we were eager to do it. After all, we live in a city that proclaims itself as the sunniest city in the United states with 350 Days of Sunshine. Last month we generated more power than we consumed. We still have to pay some taxes and fees but for all practical purposes our bill was zero. And if you care about being green, our net consumption was negative! Have you considered solar power?
