The Washington International Energy Conference wrapped up Thursday after three days of discussions, presentations and networking between more than 7,000 representatives from over 100 countries.

The United States pledged to continue its leadership in renewable energy through efforts coordinated by multiple agencies. For example, USDA will work on the development and cultivation of switchgrass for the production of cellulosic ethanol, and drive up markets and demand for woody biomass and biobased products.

“Renewable energy presents a promising opportunity for the farm economy,” said Agriculture Secretary Ed Schafer. “Coupled with a strong commitment from USDA, our goal sets renewable fuels on the pathway as a regular and reliable source in the energy mix,” Schafer said.

Ministers and representatives from other countries also shared their pledges with the conference, including Australia, Brazil, Canada, Cape Verde, Denmark, Germany, Jordan, New Zealand, and Norway.
