20080921_62 Solar power station
A part of the Wilpena solar power station. In the boxy sheds are several diesel generators that actually do most of the electrical generation. Still, the solar is a step in the right direction.
Wind power is sustainably generating about 26% of South Australia's power in 2012, but solar power is becoming more economically competative all the time. (ramblingsdc.net/Australia/WindPower)
