Australia’s march to solar power is a reason for climate optimism because it is happening under adverse circumstances. Australia has a big and important coal industry that spends millions on lobbying and election campaigns, and the Australian government is in its back pocket. They, too, have the fraud of “clean coal” hopes [that is not a thing]. The central government is no friend of renewables. Some state governments are deeply committed to dirty coal as well. Australia has a horrible environmental record and is among the worst carbon polluters per capita.
