Australian scientists claim just by harnessing one percent of the country’s untapped geothermal energy from underground could produce 26,000 years worth of clean electricity power.
Australia is the world’s biggest coal exporter and primarily uses coal power to generate nearly 77% of its electricity. But recently the government wants to invest in more renewable sources.
The government announced today that it will allocate A$50 million (US$43 million) to help develop new technology to convert geothermal energy into electricity.
Resource Minister Martin Ferguson told Reuters:
"Geothermal energy which is sometimes known as hot rocks has got a huge potential for Australia, both as a solution to climate change and in terms of national energy security,"
The power is generated from geothermal sources by pumping water below the ground and the water is heated by the high heat source. The hot water is converted to steam, which then drive the turbines to generate power and electricity.
The earth central core (is about 9,000 degrees Fahrenheit) and the surrounding cores are very hot, but drilling to the center is impossible with current technologies. Luckily for the scientists, the geothermal sources are not far off from the grounds. Geoscience Australia, a governmental organization mapped the countries geothermal sources using the temperature recordings from oil and energy drilling firms’ recorded data from 5,722 petroleum and mineral boreholes. Some sources are located just five kilometers (three miles) from the ground.
