Let's just say you probably won't be installing a wind turbine in your backyard anytime soon. Even if the homeowners association didn't come after you with torches and pitchforks, the truth is most places aren't breezy enough.
But in many areas it is possible to sign up with an electricity provider that gets its juice from renewable sources, often including wind. Your monthly bill may be about $10 higher, but you'll be doing your bit for the planet.
Go to the Department of Energy's Green Power Network to find your local provider.
The sun
A solar water-heating system can reduce the fossil fuel you'll need for showering and washing clothes. Before installing one, determine whether you have a sunny enough location to recoup the up-front costs, which can range from $3,000 to $8,000.
A solar electricity system can be pricey too. But if you're building, consider having your home pre-wired for it (for an extra $1,500 or so). Then you can install photovoltaic panels after they get cheaper (as they undoubtedly will).
