This study uses data on residential energy consumption from large nation-wide surveys in 1990, 1997, 2005, and 2015 to assess the racial inequality in residential energy consumption. The results indicate that the overall inequality in energy consumption/cost varies little over the past 25 years while showing widespread energy poverty in the U.S. In terms of racial differences, African-American households are more vulnerable than white and Asian households, and about one-third of them lived in energy poverty by 2015. However, the share of households in energy poverty witnessed the greatest growth among white households during 1990-2015. In addition, the energy burdens of different racial groups vary greatly with respect to energy types, end-use demands, and regions, given the differences in climate and households' socio-economic characteristics. The study suggests that besides low-income African-American households, urgent attention should be given to the increasing number of white households in energy poverty. |
