There are graphs at http://www.eia.gov/todayinenergy/detail.cfm?id=18131 http://www.eia.gov/todayinenergy/detail.cfm?id=18131 showing the primary heating fuel choice, based on a US survey from about 6 years ago. Among other things: > Everywhere but Northeast, fewer homes choose natural gas as heating fuel > EIA data show that homes built since 1970 use electricity and natural gas as their main heating fuel in roughly equal proportions. > The South is the only Census region where electricity is the main space heating fuel in the majority of homes.
