(BEIJING, June 21) -- A total of 1,124 solar panels have been installed on the roof of the National Indoor Stadium, a venue for the 2008 Olympic Games.

The panels will supply up to 100 kilowatts of energy daily, enough to meet the lighting demand of the stadium's underground area covering a floor space of 20,000 square meters, the Beijing Daily quoted the constructors as saying.

The designers of the project foresee a lifetime of 25 years for the solar batteries, which will generate a total of 2.32 million kwh of energy, the equivalent of 904.8 tons of standard coal (approximately 390 grams of standard coal are needed to produce one kwh of electricity).

This means that 2,352.5 tons of carbon dioxide, 21.7 tons of oxygen dioxide and nitrogen oxide will not be emitted due to the use of these solar panels.
