Solar Heating, USA

According to the 2000 Census, Eldorado, New Mexico has the nation’s highest percentage of homes heated mainly by solar power: 13.2 percent. The numbers are pretty dismal: “According to the census, the number of U.S. homes heated primarily by solar energy fell from 54,536 in 1990 to 47,069 a decade later. Federal and many state tax credits for solar homes have long since dried up.” As of 2000, Eldorado had 317 solar homes. Also of note, 8 of the 10 cities are in Hawaii.
