AUSSIES HAVE MASSIVE HOT ROCKS FOR GEOTHERMAL
Australia's vast geothermal energy resources represent thousands of years worth of untapped power
Loz Blain, July 5, 2015 (GizMag)
“Australia is sitting on top of some of the world's most potent geothermal energy sources…Just one percent of the hot rock energy less than 5 km under the surface would be enough to meet the whole country's entire power needs for 26,000 years if it was tapped…Massive amounts of hot rock just below the Earth's surface can be used to heat water and drive steam turbines for [24/7] reliable electricity generation with virtually no emissions or environmental impact… [But much] of Australia's hot rock is simply not conveniently located close to major cities…[and] large scale power transmission can be an expensive proposition…[Also, much] of Australia's hot rock isn't porous enough to let a good flow of water through, which means…engineers need to forcibly crack the rock, slowly pumping water into an underground rock reservoir at high pressure…It's a costly process…[Finally, while] the fossil fuel energy industries enjoy some AU$4 billion in direct subsidies and tax breaks, the Australian government has allocated just AU$50 million to geothermal development…” click here for more
