How Does Geothermal Energy Work?

In this article I answer the question how does geothermal energy work and how can geothermal energy be used to generate electricity.

We as humans have for years been using up vast proportions of the Earth's natural resources for our own needs. We use up these natural resources for many purposes, such as traveling in airplanes and cars using oil that is converted into gasoline.

As these natural resources are depleted, scientist believe we can harness geothermal energy to provide us with a cheaper, longer lasting energy sources.

Where does geothermal energy come from?

Heat is naturally stored in the Earth's crust. This heat is a renewable energy that can be collected and extracted and converted into electrical power.  As it's renewable, we can't deplete it like coal or oil, although some geothermal energy locations will replenish slower than others.

Geothermal energy sources can be found anywhere from a few feet underground to several miles under the Earth's crust. You can even find wells over a mile deep that can be drilled for steam, or where hot water can be pumped to the surface for many different applications.

So how does geothermal energy work?

Geothermal energy can be harnessed in several ways but the most common is from dry steam plants. Dry steam plants take geothermal energy, the Earth's natural heating element under the Earth's crust, and convert it into electricity for human use.

Imagine being able to power your home or office by the natural geothermal heat of the Earth. This sounds like a great advance in technology, but why don't you seen it in all the major towns and cities?

Unfortunately, we are still too way dependent on oil and gas, but many places are introducing geothermal energy plants and hopefully soon, more cites and states will catch on.

There are plenty of benefits in using Geothermal Power and one of the best reasons for using geothermal energy is that it requires no fuel, which means the emissions to the environment are almost non-existent.

The potential for geothermal energy in the future is huge. A large geothermal plant can easily power an entire city, where as very small plant can power very small rural villages.
