Australia has been exporting coal and natural gas to the world while importing the clean energy technology needed to replace them and the irony of that position just deepened considerably. Researchers just accessed a vast underground geothermal heat source beneath the Australian continent that preliminary assessments suggest could supply enough thermal energy to power the entire country for thousands of years. The heat sitting beneath the Outback is not a new discovery in the geological sense as scientists have known about Australia's geothermal potential for decades. What just changed is the drilling and extraction technology that makes accessing that heat at depths and temperatures sufficient for commercial electricity generation practically achievable rather than theoretically interesting.
Geothermal energy has 1 characteristic that no other renewable source can match: it operates 24 hours a day, 365 days a year, completely independent of weather, season, cloud cover, or wind conditions. The heat beneath Australia does not fluctuate with atmospheric conditions because it comes from the decay of radioactive elements in the earth's crust, a process that has been generating thermal energy continuously for billions of years and will continue doing so for billions more regardless of what happens to the climate above it. Australia has been managing a coal dependent energy system while sitting on a geothermal resource large enough to power the continent for millennia. Researchers just tapped into it and the country that built its economy on fossil fuels extracted from its ground just discovered that what was always beneath its ground was worth considerably more than the coal it has been digging up and selling.
