LETS ADOPT RENEWABLE FORM OF ENERGY INSTEAD OF FOSSIL FUELS |
|---|

Geothermal energy is the heat energy in the Earth?s interiors. The temperature at the center of the Earth is about 6000C. In some areas, molten rock is found very close to the surface of the Earth. This hot rock meets underground water and heats it up. This produces steam. Such a place is known as a hot spot. Sometimes, this heated underground water finds an outlet through which it comes out on the surface of the Earth. Such outlets are known as hot springs. Advantages No fuel is needed. Once built, however, a geothermal power plant can generate electricity 24 hours a day with low operation and maintenance costs importantly because there is zero fuel cost. Once a geothermal power station is built, the energy is almost free. Over the life of the generator, geothermal plants are often cost-competitive with all other power sources, including fossil fuel and nuclear plants. This is true even without considering the many indirect costs of fossil- and nuclear-generated electricity that are not reflected in customers? monthly bills. It does not produce any polluting emissions and does not contribute to the greenhouse effect Since geothermal power stations are not very large, they have a minimal impact on the environment Unlike other sources of energy this coal and petrol, geothermal energy is renewable and eco-friendly. In 2013, world geothermal electricity-generating capacity grew 3 percent to top 11,700 megawatts across 24 countries. Although some other renewable energy technologies are seeing much faster growth—wind power has expanded 21 percent per year since 2008, for example, while solar power has grown at a blistering 53 percent annual rate—this was geothermal?s best year since the 2007-08 financial crisis. The top three countries in installed geothermal power capacity—the U.S., Philippines and Indonesia—account for more than half the world total. California hosts nearly 80 percent of the 3,440 megawatts of U.S. geothermal capacity another 16 percent is found in Nevada.
Geothermal energy will help us in reducing energy poverty, air pollution, carbon emissions and costly fossil fuel imports. So let?s adopt it and spread the message about it. |

Dependence on fossil fuels decreases with the increase in the use of geothermal energy. With the sky-rocketing prices of oil, many countries are pushing companies to adopt these clean sources of energy. Burning of fossil fuels releases greenhouse gases which are responsible for global warming. This is one of the main advantage of using geothermal energy since it does not create any pollution and help in creating clean environment. Being the renewable source of energy, geothermal energy has helped in reducing global warming and pollution. Moreover, Geothermal systems does not create any pollution as it releases some gases from deep within the earth which are not very harmful to the environment

Well written Afra.
Geothermal energy is the clean and sustainable source of energy and should be realized to it's full potential.

Thx for the report...not many report I have seen on this interesting topic since in this forum...Geothermal energy is having lots of potential to be explored further...I believe the technological development in this field will play a major role in this regard in near future...

Thanks , Afra for detailed article on Geothermal energy. There is no doubt that geothermal energy is the clean and sustainable source of energy and should be tapped to it's full potential. I read somewhere that the Earth's geothermal resources are theoretically more than adequate to supply humanity's energy needs. Thanks for emphasising the need to adopt renewable energy.

Thank you Gaa Bhin Ryu
Yes the graph shows the increase in the no. from 1950

Geothermal energy, in areas where it is possible to be produced, is and will be so important for our society. As the number of geothermal plants are constantly cumulating, we will receive more energy and less pollution. I like that graph you found.

Welcome!
That is so true.

The graph suggests that the use of geothermal energy will go on increasing, which is of course a great news and so far I regard it as the best solution of energy crisis. Country with hot springs should readily opt for this, thank you for illustrative report.
