Geothermal energy is a great source of renewable energy that has yet to become as mainstream in conversation as other sources like water, wind, solar power. For one, it is renewable and therefore more sustainable and better for the environment than coal and other fossil fuels. The rate of extraction for geothermal heat is so that the demand does not outweigh the supply. Another benefit of geothermal energy is that is can produce energy despite any weather conditions. While a great renewable option, solar power relies on weather conditions, and can’t operate 24/7 like geothermal energy. Additionally, geothermal energy could be harnessed both domestically and imported, making it a valuable asset. Geothermal power plants do not emit greenhouse gases and they consume less water than other plants.
