No Description

Geothermal energy is a renewable energy source. Geothermal is also a heat that is made by the earth. It's a clean and sustainable energy source.
You can find geothermal energy from the shallow ground to hot water and hot rock found a few kilometers beneath the earths surface and down even deeper to extremely high temperatures of molten rock called magma.

Deep in the wells a kilometer or more deeper can tap the reservoirs (natural lake) of steam or very hot water that can be used to drive large turbines which powers our electricity generators that we use in our daily life
What happens is the large wells collect the geothermal energy to power large turbines that power our electricity generators that power our lights and our electronics

1. The first type is dry steam power plant which is used to generate power directly from the steam generated inside the earth
2. The most common type of geothermal power plant is flash steam plants. Flash steam plants use water at temperatures greater than 182 degrees Celsius.

According to geothermalcommunities.eu carbon dioxide, hydrogen sulfide, methane, and ammonia These emissions are lower than those associated with the use of fossil fuels for which the adoption of geothermal energy sources is considered to have the potential to mitigate global warming and have a favorable impact on the environment.

According to geo-energy.org Geothermal energy provides long-term answers to some of the most pressing issues in today’s economy. Warning signs of climate distress and volatile fuel costs are leading people to question where their power comes from and how rising energy costs will affect their communities and businesses. Unlike coal and natural gas, geothermal incurs no hidden costs such as land degradation, high air emissions, forced extinction and destruction of animals and plants.

Countries generating more than 15 percent of their electricity from geothermal sources include El Salvador, Kenya, the Philippines, Iceland and Costa Rica. Geothermal power is considered to be a sustainable, renewable source of energy because the heat extraction is small compared with the Earth's heat content. Australia uses 6.8% of geothermal energy

According to environment.nationalgeographic geothermal power plant in Reykjavik, Iceland, is using their underground reservoirs of steam and hot water to generate electricity and to heat and cool buildings directly. Geothermal energy has been used for thousands of years in some countries for cooking and heating.
