“Economic Census Statistics Now Available for the First Time on Wind, Geothermal, Biomass and Solar Electric Power Generation. Revenues for electric power generation industries that use renewable energy resources rose 49.0 percent from $6.6 billion in 2007 to $9.8 billion in 2012, according to new economic census statistics released today by the U.S. Census Bureau. These industries that use renewable energy resources consist of hydroelectric power generation (NAICS 221111), four newly delineated industries — wind (NAICS 221115), geothermal (NAICS 221116), biomass (NAICS 221117) and solar electric power generation (NAICS 221114) — and one newly defined category of other electric power generation (NAICS 221118).  In the 2007 Economic Census, wind, geothermal, biomass, and solar electric power generation were included in the broad “other electric power generation” industry (NAICS 221119). By the 2012 Economic Census, these industries had been broken out separately, with the “other electric power generation” industry limited to only tidal electric power generation and other electric power generation facilities not elsewhere classified. Among the newly delineated industries (wind, geothermal, biomass, solar and other electric power generation), the number of establishments more than doubled in five years, from 312 in 2007 to 697 in 2012.”
