    The City of Melbourne is generating 252,000 kilowatt-hours of electricity each year from what is the largest urban solar installation of its kind in the Southern Hemisphere. Housed on the roof of the historic Queen Victoria Market, the system has cut CO2 emissions by 1,314 tons since it was installed in 2003, and is providing enough energy to power 46 homes a year. The installation showcases the benefits of renewable energies to the public and tourists with a real time display on-site of kWh generated and CO2 emissions saved. Importantly, it demonstrates that solar can be applied to historic buildings and dead urban spaces such as rooftops.
