Twice as many people attended this year's renewable energy expo on Capitol Hill than last year. The 3rd annual House Renewable Energy Expo, on May 21, drew 2800 people, up from 1400 in 1997. Many of those attending were members of the US Congress, senior staffers and officials from the Clinton Administration, according to the organisers, the Washington-based Sustainable Energy Coalition. "It's important for the future of our country that we at the federal level show strong support for renewable energy and energy efficiency," noted Democrat Congressman David Minge from the event. Another senior backer of renewables was outgoing US Secretary of Energy Federico Peña. After the expo, US Representative Dan Schaefer said: "If we don't look at some kind of green power in the future, such as renewable energy sources, our grandchildren's grandchildren are going to run out of money." Schaefer is a founding member of the House Renewable Energy Caucus, which backed the event and whose membership has grown to 124 since its founding.
