This map shows quite a few of the best locations for organic hot spots perfect for geothermal energy extraction.
Generating electricity with standard steam turbines demands functioning fluids at temperatures of at least 150 °C. This is only possible with higher temperature geothermal sources of steam or superheated water which can be flashed to steam. The diagram under shows some of the achievable variants when high temperature water or steam is obtainable.
Today is the era of non-traditional sources of power. Till now India has tapped the possible of wind, tidal, solar and nuclear energy only. But geothermal technologies is nevertheless to appear in India. The Indian government has taken few modest steps in this regard. Considering the prospective applications of geothermal power and the present Indian energy scenario, it is higher time that India exploits this source of power to the fullest and makes a mark in the field of power production.
Geothermal energy is heat contained inside in the earth. Australia has great potential for geothermal power to be applied for electrical energy generation and for direct use applications. Electrical energy can be generated utilizing temperatures as low as 100°C, although higher temperatures than this could be necessary for larger scale production. For direct use applications, temperatures of 30°C and above can be used in industry, agriculture and for heating and cooling of residential buildings (see Reality sheet Direct-use of Geothermal Power Opportunities for Australia ).
Texas has thousands of wells that have higher sufficient temperatures for the achievable improvement of geo-pressured and geothermal resources. Geothermal power can be generated anyplace in the state. Nevertheless the most significant technical challenge facing geothermal improvement is determining exactly where and how deep the resources are and how organizations can get to and utilize them.
