September 7, 2007—Renewable energy consumption increased 2% in the US between 2004 and 2005, according to a new report from the US Department of Energy’s (DOE) Energy Information Administration (EIA). The EIA’s “Renewable Energy Annual, 2005” notes that total US energy consumption was essentially flat in 2005, causing renewable energy’s market share to increase to nearly 7% of US energy use.
The report notes that wind power grew most rapidly in 2005, increasing by 26%, while the biofuel industry experienced the second most rapid growth, at more than 15%. Breaking the numbers down further, the EIA found extremely rapid growth in the biodiesel industry, which experienced a four-fold increase in production in 2005.
The EIA report is actually a compilation of four reports, which examine overall renewable energy trends, shipments of solar energy collectors, shipments of geothermal heat pumps, and trends in green pricing and net metering programs.
The solar collector report notes that domestic shipments of solar thermal collectors increased by 10.4%, while exports grew by 67.4%. For solar cells and modules, domestic shipments surged by 72%, but exports fell 10% as U.S. manufacturers focused on the growing domestic market. Foreign companies also zeroed in on that market, increasing imports by 91%.
Net metering also saw a 34% growth in 2005, mainly for solar power systems. California provided most of that growth, followed by New Jersey. Geothermal heat pumps also experienced a growing market, with shipments increasing by 9% to the highest level yet recorded by EIA. Nearly all geothermal heat pumps produced here are sent to destinations within the US, says the agency.
