Geothermal Power

Geothermal power is an old energy, in which it exists since a long time ago. Actually this energy exists alongside with our plant since its born day. Again, geothermal power is energy from the heat from the earth. It’s clean, cost effective, reliable, and environmentally friendly. We can keep this energy because it is renewable. We can find hot water and hot rock starting from superficial area to little miles below the surface of the Earth and even deeper to great heat of molten rock (magma).

There are problems around the world as global warming and public health risks that results of use of fossil fuel so many countries decided to reduce dependence on it and start using to geothermal power.

The American Paleo-Indians were first who discovered the geothermal power in hot springs and that traced back to over 10,000 years ago. They discovered the geothermal energy through using the hot spring for their activities like bathing, cooking and cleaning.

The begging of serving of geothermal power in the industrial business was in 18^th century close to Pisa, in Italy. The first time generated power from the steam successfully when the first geothermal energy factory constructed in 1904 which belong to Larderello Fields. Through 1960's, USA constructed first industrial factory for geothermal power and it could generated 11 Megawatts of electricity and that electricity was environmentally friendly and renewable. This was looked as a huge move towards power of the future.

After 1960’s, the geothermal power started to be developed and improved by many organizations and the governing bodies. In 1967 in Russia, the first bilateral cycle energy factory was constructed. Also subsequent in 1981 the first one in USA was constructed. This technology accepted the application of much lower temperature resources than in the old-time. In 2006 in Alaska, a bilateral cycle plant generated electricity from a score low liquid temperature of 57°C. Geothermal electric plants have been created lately where great temperature geothermal resources are obtainable close to the superficies of earth. The thermal qualification of geothermal electric factories is low, around 10-23%, because geothermal liquids are should be at a less heat. By the laws of thermodynamics this little heat bounds the qualification of heat engines in elicitation helpful energy during the generation of electricity.

Today, people use the geothermal power in swimming pools to heat the water and use it in health spa. We can use the hot water from below the ground to warm the buildings for growing plants, similar to greenhouse effect.

In the south of California, the hot water from below the ground is used to heat the buildings during the winter. In Iceland, many of buildings and swimming pools are heated with geothermal hot water.

If we talk about the future for the geothermal power, we will find big future because it is renewable energy and can supply continuous, baseload power. As we can consider this power source as a free energy when in return it is an alternative energy to the current polluted energy source we are using, like the fossil based energy.
