For many years I have been concerned about climate change, so, about 3 years ago, I started reducing my own energy use.  I worked with Efficiency Vermont, the Zero Energy Now Program, and the Weatherize the Upper Valley Program to improve my insulation, add heat pumps, and buy shares of Randolph Community Solar.  The net effect of this work has been to make my house more comfortable, generate my own electricity, and almost completely eliminate my use of fossil fuels.  I also believe that I have increased the resale value of my house, an added bonus.
