How Do Humans Harness The Earth’s Energy?

Deep inside of the Earth, there is a lot of energy stored. The Earth’s mantle is super hot, meaning that is has a lot of energy in it! But, how do humans harness that energy for electricity? They make geothermal electricity. Geothermal power is a renewable source of making electricity. It harnesses the heat from Earth’s layers to do so. First, humans drill deep into the Earth’s crust where there will be some heat from volcanoes or hot springs. Then, they inject cold water into pipes in the ground and the heat turns it into steam, which turns a generator to produce electricity! Then, the cooled water is injected back into the ground and the process starts all over again!!
