HFR geothermal energy is produced using heat extracted from buried hot granites by circulating water through an engineered, artificial reservoir or underground heat exchanger. These hot granites represent a massive source of renewable energy, free from CO2 emissions.
The development of HFR geothermal energy relies on existing technologies. HFR geothermal projects are currently underway in France, Switzerland, Germany, California, and Japan. Australia has a recognised potential for the development of HFR geothermal energy.
Perhaps HFR is the answer to the world's future energy needs - a source that does not exacerbate the problem of global warming, is safe and seemingly available in infinite supply. This report entitled, "The Future of Geothermal Energy" suggests that the amount of extractable HFR energy exceeds the world's current consumption by a factor of several thousand!
To quote Sheikh Yamani: "The Stone Age did not end because people ran out of stones - it ended because they found something better."
