The always venerable Big Gav - the smartest writer of the Oil Drum - has this bit on a 100% solar-powered stadium in Taiwan (great pictures):
Taiwan recently finished construction on an incredible solar-powered stadium that will generate 100% of its electricity from photovoltaic technology! Designed by Toyo Ito, the dragon-shaped 50,000 seat arena is clad in 8,844 solar panels that illuminate the track and field with 3,300 lux. The project will officially open later this year to welcome the 2009 World Games.
Building a new stadium is always a massive undertaking that requires millions of dollars, substantial physical labor, and a vast amount of electricity to keep it operating. Toyo Ito’s design negates this energy drain with a stunning 14,155 sq meter solar roof that is able to provide enough energy to power the stadium’s 3,300 lights and two jumbo vision screens. To illustrate the incredible power of this system, officials ran a test this January and found that it took just six minutes to power up the stadium’s entire lighting
The stadium also integrates additional green features such as permeable paving and the extensive use of reusable, domestically made materials. Built upon a clear area of approximately 19 hectares, nearly 7 hectares has been reserved for the development of integrated public green spaces, bike paths, sports parks, and an ecological pond. Additionally, all of the plants occupying the area before construction were transplanted.
