CAIRNS, Australia — Australia is the world’s second-largest exporter of coal, which plays an outsize role in its economy and politics. But the country has also quietly become a renewable energy powerhouse.
About one in four Australian homes have rooftop solar panels, a larger share than in any other major economy, and the rate of installations far outpaces the global average. The country is well ahead of Germany, Japan and California, which are widely considered leaders in clean energy.

Politically conservative homeowners have also embraced solar to become less reliant on the electricity grid in keeping with the high value many Australians place on rugged individualism.
In two of the country’s most populous states — Queensland, a conservative stronghold, and New South Wales, home to left-leaning Sydney — as many as half of homes have solar panels.

But many state governments have
