21 billion gallons of algal oil with American grown algae ! 9

Researchers at the Department of Energy's Pacific Northwest National Laboratory found that water use is much less if algae are grown in the U.S. regions that have the sunniest and most humid climates: the Gulf Coast, the Southeastern Seaboard and the Great Lakes.

"Algae has been a hot topic of biofuel discussions recently, but no one has taken such a detailed look at how much America could make - and how much water and land it would require until now," said Mark Wigmosta, lead author and a PNNL hydrologist. "This research provides the groundwork and initial estimates needed to better inform renewable energy decisions."

Algal biofuel can be made by extracting and refining the oils, called lipids, that algae produce as they grow. Policy makers and researchers are interested in developing biofuels because they can create fewer overall greenhouse gas emissions than fossil fuels. And biofuels can be made here in the United States. In 2009, slightly more than half of the petroleum consumed by the U.S. was from foreign oil.
