Biofuels, wind power show gains, but hurdles remain

November 10, 2011 | 11:14 am

Biofuels and wind power are having the biggest new impact in American power generation, according to a report released today by the U.S. Energy Department. Consumption of biofuels has risen 16-fold since 2000 and wind power use has seen an eight-fold increase during the same period.

Among renewable energy sources, only solar power is rising faster, the Energy Department said. But solar and photo-voltaic power are still the smallest contributors to the nation's energy needs, accounting for just 1% of the renewable total.

Hydroelectric power remains the biggest resource, at 31% of all renewable energy produced in the U.S., but it is not a growing resource. Wood is next, at 25%, followed by biofuels (23%), wind (11%), waste (6%), and geothermal (3%). Altogether, renewables account for 8% of U.S. energy production.

The Energy Department said that improved technology was part of the reason for the growth in electricity generation from wind power, which rose from about 6 billion kilowatt-hours in 2000 to about 95 billion kilowatt-hours in 2010. But the Energy Department also cited the importance of financial incentives in the form of federal production tax credits and grants.
