Australia loves coal. About 60% of our electricity still comes from polluting, coal-fired power plants, while only 20% comes from renewables. Successive governments have told us that decommissioning coal-fired power would hurt the economy and cause a wave of unemployment. But that's not actually true. In fact, there are enormous opportunities to create jobs and wealth in renewable industries in Australia, including in exporting to countries without the sun and space we enjoy here.
