This year's conference and exhibit hall used green power donated by the Bonneville Power Administration to offset pollution from the event's electricity consumption. The power, represented by "green tags," was generated by the Stateline, Condon and Foote Creek wind farms, in Washington, Oregon and Wyoming. The tags represent the production of 45,000 kWh of electricity, the amount needed to power the conference and exhibition halls throughout its four days. "In effect, it is as though we were purchasing clean energy directly from those wind farms to power the event," said Randy Swisher of the American Wind Energy Association. AWEA decided to highlight the use of green tags to draw attention to what Swisher called a "simple and convenient" way to buy green power. A green tag certifies that a given amount of electricity from a renewable energy source has been produced, reducing the need for power from a polluting plant. The green tag represents the avoided pollution, not the electricity itself, so its purchase allows consumers to support green power generation even though that electricity may not directly flow to their meter.
