For the first time the U.S. Census Bureau is now publishing economic census statistics for wind, geothermal, biomass and solar electric power generation. Between 2007 and 2012 revenues rose 49 percent from $6.6 billion to $9.8 billion. The electric power generation industry saw an overall decline of 1.2 percent in revenues from $121.0 billion to $119.5 billion between 2007 and 2012. The overall decline was driven by the fossil fuel electric power generation industry, which saw revenues decrease from $85.4 billion to $79.7 billion, or 6.7 percent, during the same five-year period.

In the 2007 Economic Census, wind, geothermal, biomass, and solar electric power generation were included in the broad “other electric power generation” industry but were not given separate designations. Beginning in the 2012 Economic Census, these industries had been broken out 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.

“As industries evolve, so does the Census Bureau to continue to collect relevant data that informs America’s business decisions,” said Census Bureau Director John H. Thompson. “Industries that use renewable energy resources are still relatively small, but they are rapidly growing.”

Specifically revenues for the wind electric power generation industry totaled $5.0 billion in 2012, the highest revenues among the industries using renewable energy resources. Hydroelectric power generation followed with revenues of $2.4 billion. Geothermal electric power generation had revenues of just under $1 billion ($995.4 million), followed by biomass electric power generation, with $934.6 million in revenues, solar electric power generation, with $472.4 million, and other electric power generation, with $59.0 million.

Together, these industries were a relatively small portion of the electric power generation industry, collectively accounting for just 8.2 percent ($9.8 billion) of total industry revenues in 2012. Fossil fuel and nuclear electric power generation are still the major revenue sources of the electric power generation industry, comprising 66.7 percent ($79.7 billion) and 25.1 percent ($29.9 billion), respectively, of total revenues.
