The trade show at the Washington International Renewable Energy Conference closes today, at the Walter E. Washington Convention Center, after a five-day run. The 200 exhibitors (ranging from big businesses to nonprofits) and 11 international pavilions offered new products and educational information to the 2,000 attendees at the conference's receptions and workshops (including a visit from President Bush on Wednesday). This year marked the conference's first in the U.S., after previous stops in Beijing and Bonn, Germany. With many booths built to impress, here's a look at some of the large-scale displays and conversation-friendly planning.
