Renewable energy played its part in ensuring the success of the 2000 Olympic Games,

For Example:-

• In the Olympic Village, rooftop-mounted Photovoltaic (PV) panels generated one million kWh/year, while passive cooling designs and energy efficiency cut energy by 50%.
• 19 solar towers equipped with PV modules were installed along the main road of the Olympic site; with a total capacity of 133kW (peak), they can generate 160,000 kWh/year of electricity.
• The roof of the Super Dome - the venue for the gymnastics and basketball - incorporates PV modules with total capacity of 70kW (peak).
• Thermal solar collectors heated the Olympic swimming pool.
• All the building construction of the games incorporated bio climatic architecture to take the environment into consideration: for instance, Stadia harness the wind to run natural ventilation systems, saving substantial quantities of energy compared to traditional air-conditioning.
  
  This use of renewable's helped to underline the growing global role they will play as the third millennium progresses.
