How Green Is Wind Energy?

You may not think about wind energy that often. To be specific, wind energy refers to the process of creating electricity using the wind or air flows that occur naturally in the earth’s atmosphere. Most frequently, this energy is collected using wind turbines. This may pose some problems, but first, let’s take a look at what wind turbines are.

The Difference Between Windmills & Wind Turbines

People often refer to these two entities as though they are the same. They are, however, different. Windmills generate mechanical energy that we use for things like grinding grain – and they’ve been doing that for centuries. Windmills do NOT generate electricity. Wind turbines turn the winds kinetic energy into electricity.

How Wind Turbines Work

These giant towers stand around 260 feet tall. They can manuever around to the perfect angle, or “pitch,” so they may face the wind to capture its energy optimally. They typically start generating energy when wind speeds reach 6-9 miles per hour, which is known as the cut-in speed. Not to mention, they can power down when winds get too harsh to prevent damage.

The Problem With Wind Turbines

Disposal of wind turbines is, most often, a recycle of the parts. However, there are quite a few (approximately 10%) of those turbines that have fiberglass blades. These blades present an issue in that they are not reusable.

While 10% may not sound like all that much, there are currently over 57,000 wind turbines in the united states. That’s approximately 5,700 units with no recyclable blades. Since each turbine has three blades, that’s over 15,000 blades.

Considering the size of these blades, disposing of them is no small feat. So, one landfill in Wyoming has come up with a solution. To bury the wind turbine blades. This is costly and not great for the environment.

Geothermal – The Alternative to Turbines

The way we see it, if you’re going to bury something green, it should be geothermal pipes. You see, to put a new geothermal unit in your home, we have to bury the pipes that carry the heat & cold from the earth to your home into the ground. Not only is it a huge cost saver for you, but its a great boon to the environment!

So, if you’re ready to take your home in the direction of green energy, go with geothermal! Give us a call if you want a system in your home.
