Oct 21 (Reuters) - U.S. coal consumption fell 3 percent last week and was down 10 percent from the same week a year ago, according to power industry data monitor Genscape.
Coal use swings up and down seasonally, and varies from week to week and region to region, depending on electricity demand to run air-conditioners or power heaters.
Economic activity also is a factor.Coal plants produce slightly less than 50 percent of U.S.electricity. Power generation accounts for more than 90 percent of U.S. coal consumption.
Genscape's regional indexes are calculated separately from the national index and do not always add up to the separately calculated U.S. total.
Following is a table on coal consumption, in million tons.
