recovery and reinvestment act of 2009

Any green home worth its weight in compost draws heavily on solar energy. Mine is equipped with all the standard offerings, such as a solar-powered boiler, the subject of my last column. Trouble is, the sun doesn’t always shine. So to make up the difference during cold, dark winters and rainy spells, I’m turning to another eco-friendly energy source: my backyard. The two 325-foot-deep geothermal wells I’m boring there will use the constant 50°F temperature of the Earth at that depth to meet all my extra heating and cooling demands.
