There is a local person here who is using the cooking oil for fuel in his heating oil company, I think you have to make a slight moderation to your burner, and he has a list of things that you have to do to your diesel truck engine to use it. But its becoming popular here finally.
And we have a solar thing on our house, its amazing what heat it puts out on a sunny winter day!
And maybe you have read of the proposed wind farm here between Hyannis and Nantucket. That is a good idea, but the funding is all messed up, and the fact that we dont have much wind at night might not be economical. It would take a long long time to put enuf into the powergrid to make up for the initial cost. But still, all these things are are very important to work on.
Nuclear power too, they would relieve a lot of our dependency on importing oil. But president Carter(no relation!)stopped the re-processing of uranium. History Channel again. I would have to ask my husband the details on that, but I would think that nuclear power generation could be upped.
All these things combined could really make the USA a lot more self sufficient.
I can sure say that even here in New England, solar can really make a difference.
On the coldest(sunny) days, we can shut our heat off, turn the fan on manual, and heat the house from our one solar room. February is the best.
