Adelaide in South Australia, host city last month for the Global Wind Energy Council's 2006 conference and exhibition, Global Windpower, bills itself as Australia's green city. And so enthusiastic about wind power is the state's premier, Mike Rann, that he is installing five two metre rooftop wind turbines on office buildings, including his own, around the Adelaide Central Business District. "The mini wind turbines installation is another example of our commitment to renewable energy initiatives," he says. Each turbine produces 1.5 kW or between a third and a half of an average household's electricity requirements and will prevent 1.4 tonnes of greenhouse gas entering the atmosphere each year.
