Step in the right direction. Solar, wind, water, we should be working to harness this stuff more than we do.
Let's say it costs you $1,000/yr. for heating oil and $1,000/yr. for electric bills. You will have those bills for as long as you own a home. What if you spent $10-20k on solar/wind/water systems (depending on where you live) instead of relying on the grid and heating oil?
If you spent 20k it would pay for itself in 10 years. How long do you expect to live in a house? 50 years? That equals about 40 years of no or extremely low cost energy for your house.
If my wife and I build our next home, we will look into it.
Edited to add: The electricity/heating oil costs are today's prices, too. Who knows what the prices will be in 10, 20, or 40 years. What's the wind cost now? What will it cost in 40 years? Zippo.
