Australia Could Attain
100 Percent Renewables by 2050, Study Says

Australia could reduce its greenhouse emissions significantly and transition to an economy predominantly fueled by renewable energy for very little cost, according to
an analysis by the Australian National University and WWF. The country could generate 100 percent of its electricity from renewables and have zero net emissions by 2050 because wind and solar technologies have fallen rapidly in price in recent years and Australia is the world's sunniest and windiest continent. Any progress, however, will depend on the government's willingness to set clear, long-term policies and regulations encouraging renewable energy use, the authors note. Under conservative Prime Minister Tony Abbott, Australia's current climate action plan calls for only a five percent cut in emissions from 2000 levels over the next five years. That plan has been challenged
by the U.S., China, and other countries, however, which contend that the program would have no real effect on mitigating global climate change.
