ENERGY FROM THE VOLCANO
Since our community is a home more than a hundred volcanoes, energy has been tapped from them. Actually, the Philippines ranks second in the world's production of geothermal energy. According to the Department of Energy, 14.4% of the country's total power generation is produced from geothermal energy. The production of electricity from geothermal energy. The production of electricity from geothermal energy is cheaper than the electricity production using natural gas, coal and hydropower.
WHAT IS GEOTHERMAL ENERGY?
The Earth is believed to be extremely hot from within. This heat from the Earth's interior is a source of energy called geothermal energy. The heat of the Earth warms up water which is tapped in rock formations beneath its surface.
HOW IS GEOTHERMAL ENERGY GENERATED?
Geothermal energy is generated in two ways: geothermal power plants and geothermal heat pumps. They differ in the depth of heat source to produce energy.
In geothermal power plants, the heat from deep inside the Earth is used to produce steam to enerate electricity compared with geothermal heat pumps that use the heat coming from close to the Earth's surface to heat after oprovide heat for buildings.
In the Philippines, geothermal power plants are used to generate electricity in Tiwi (Albay), Kidapawan (North Cotabato), Calaca (Laguna), Tongonan (Leyte), Bago City (Negros Occidental), Valencia (Negros Oriental) and Bacon (Sorsogon).
