<font color=blue>the power company HAS to buy excess power he generates</font color=blue>
Bob - over the weekend I talked to an old buddy whose adult life has been dedicated to alternative energy resources. At his own house, he has a large array of solar cells on the roof feeding a bay of storage batteries in his basement. When the batteries are fully charged, the excess juice is converted into AC and is simply pumped into the power company's grid. He says it's quite simple -- if the demand from his house is less than the supply he is generating, the current simply starts flowing backwards through the meter onto the main grid. The electric meter is a simple device and it just runs backwards itself, thereby lowering his effective usage. You
could say the power company is buying it back, but as you can see, it's even simpler than that. BTW -- this whole procedure is sanctioned by the power company.
Coincidentally, even before this energy crunch began, I was looking into alternative energy sources for my tractor property. So far it looks like I might be able to run just the lights through solar cells, but I'd have to mount them on a tower to overcome the shade of the trees. During the winter I might be able to harness the overflow from the pond by hooking up my own little turbine generator. A windmill probably wouldn't do well in that area -- just not enough wind on most days.
The real problem is heating the house. The existing furnace is all electric, which is a very inefficient way to go. The simplest route there might just be to put in a propane system (although propane is getting pretty pricey, too). I've been following the threads on woodburners and geothermal heat pumps, but I'm not sure the answer is there, either.
BTW - I occassionally drive through the Altamont Pass "wind farm" that RobertN mentioned (last time was to buy my tractor /w3tcompact/icons/smile.gif). It's really one of the most amazing sights you can imagine -- hundreds, if not thousands, of giant windmills covering the landscape as far as the eye can see. You drive for mile after mile and the windmills just keep popping up on the horizon. The attached picture shows but a tiny fraction of the "farm".
