Although the rest of the country has seen per-capita energy consumption level off as efficiency gains are made, California still uses less energy per household than the national average, according to an Energy Information Agency analysis Aug. 14. \tOn average, according to the agency, California homes use 31 percent less than the national average for household energy use, with average electricity consumption standing the lowest among states. \tCalifornia homes are smaller than those in the rest of the nation, averaging 1,583 square feet compared to the national average of 1,971 square feet. California homes also are less likely to have air conditioning. Less than 60 percent are equipped with air conditioners, compared to more than 80 percent nationwide. \tThe agency observed that\u2019s primarily because the state\u2019s population is concentrated along the coast where temperatures are mild. \tYet, while energy use is 31 percent lower here, household expenditures for energy are not quite commensurately lower due to the state\u2019s relatively high price for electricity, according to the agency. The average household here spends about $1,500\/year for energy utilities, compared to around $2,000\/year nationwide. That\u2019s about a 25 percent difference.
