Australia with plans for global change in energy policy
Australian scientists have calculated that only one percent of unused geothermal energy in the country can produce clean electricity that will meet the needs for the next 26 thousand years, Reuters reported. Australian government announced that it will put 50 million Australian dollars in a project to develop technology for geothermal energy.
Geothermal energy, sometimes called "hot rocks", there is huge potential in Australia - both in terms of combating climate change, and for national energy security, indicates the Minister of the resources of the South continent - Martin Fergusan. Currently 77% of electricity in Australia is produced from coal, but aims for 20% renewable energy by 2020 remain. While Australia is not the largest global pollutant and contributes to 1.5% of global emissions of greenhouse gases per capita, it is number one with five times more emissions from China.
To create electricity from geothermal energy is inserting water under the earth where water is hetting hotter, and a heat energy is used to generate electricity. Governmental organization Geoscience Australia already created a maps of geothermal energy in the country, using data from mining and energy companies, collected over the decades. On Wednesday a representative of Geoscience for Reuters said that only one percent of reserves equal to 26,000 years energy supplies.
In order to produce electricity, "hot rocks" must have a temperature of 150 degrees Celsius. Such is the temperature at depths of 1 to 5 km., Degrees in earth near the center increased. Estimates of the Association for geothermal energy in Australia show that by 2020 the country will be able to cover 40% (2200 mW) from the requirement of energy from renewable energy sources through the use of hot stones. To do this, however, needed investment from 12 billion Australian Dollars. However prices for electricity production from the ground will be significantly lower after the release of the first plant for commercial purposes.
