The choice is between leaving CO2 emissions to the markets with every expectation of large and rapid decreases in CO2 emissions or pursuing a government regulatory and subsidy approach that is unlikely to achieve anything except a bitter political and legal fight, rapidly increasing electricity rates, and rapidly
declining electricity reliability.
The fact that around 26 % of South Australia's power was produced by wind farms in 2011, and greenhouse emissions from power generation in SA
declined by about 20 % from 2005 to 2010, with no reduction in power
reliability, proves that renewable energy can provide a substantial part of Australia's
electricity needs and produce a positive contribution to the climate change crisis.
