Is there a way to make all the energy a household needs from altenative energy sources?
Yes – but you have to make some sacrifices. You can definitely power a whole house with solar, wind or a combination of the two, especially if you change the way you live. Use LED or at least compact fluorescent lights. Limit your use of things like hair dryers, toasters, clothes dryers, etc…. anything that uses electricity to heat something up. We are going to use solar and wind for our new house we are planning. We will still have computers, a washer, fridge and freezer, etc., and will heat with wood and radiant infloor heating. I guess the answer to your question is Yes, you can power a house this way… but not if you want all the things that a typical North American house has. And by the way, elul89 – we live in Canada. Just because we have cold winters doesn’t mean we get no sun! Good luck!
