Geothermal energy is a renewable energy source derived from the Earth’s internal heat. It is used for electricity generation, heating, and cooling. As countries seek sustainable and reliable energy solutions, geothermal energy has become a significant focus. This article explores how many countries use geothermal energy, examining its global presence and the factors influencing its adoption.
What is Geothermal Energy?
Geothermal energy comes from the heat stored beneath the Earth’s surface. It is harnessed through geothermal power plants and direct use applications. This energy source is considered sustainable because it relies on the Earth’s natural heat, which is virtually inexhaustible over human timescales.
Countries with Significant Geothermal Energy Usage
United States
The United States is the leading country in geothermal energy production. It has numerous geothermal power plants, mainly located in California, Nevada, and Alaska. The United States also uses geothermal energy for district heating and in geothermal heat pumps.
Iceland
Iceland is a pioneer in geothermal energy. It utilizes geothermal energy for about 90% of its heating needs and a significant portion of its electricity. The country’s location on the Mid-Atlantic Ridge provides it with abundant geothermal resources.
Philippines
The Philippines is one of the top producers of geothermal electricity globally. It ranks second in the world for geothermal electricity production. The country’s geothermal resources are concentrated in areas like Luzon and Leyte.
