While Geothermal Energy Seems Like a Great and Useful Resource, It Has Its Flaws. by Molly


Since Geothermal energy comes from the heat and energy in the core, we need a way to get into the ground and get it. There are natural vents where the

heat can escape, such as volcanoes and geysers. But, these vents are relatively rare. They also don't have very much energy, and we don't even know how to get the energy from volcanoes yet. Although we can drill holes to get energy, the initial drilling costs of doing so are expensive, and the hole will have to be miles deep! And, this drilling may release harmful gases into the air. These drilled holes don't usually have as much energy as the natural

ones. Furthermore, you can't just drill a hole anywhere and expect to get a lot of energy. The places with the most energy in the United States are the West, Alaska, and Hawaii. They could get some good power from those vents. But what about the Eastern side? We don't have a lot of geothermal energy here. We'd have to find either a way to get some of it, or an alternative.

Another problem is finding where to drill these holes and build the plants. Most of the good hotspots, or places with a

lot of geothermal energy, are located near volcanoes. But it would be dangerous to build a plant there, of course. Places nearby the poles are also excellent places, such as Norway, Sweden, and Iceland. But the weather can be very cold and harsh there.
