Have you ever wondered how the wind turbine produce power? These turbines have blades that are connected to a shaft. The shaft turns a generator which produces power. Of course this is stating it simply and we will take a closer look at this process.

Here’s a better example. Do you remember those little windmills you could stick in the front yard? Wind turbines work the same way. Obviously the technology is extremely better then those things we remember as kids, but the concept is to use wind and turn it into energy. While windmills are common, there are other terminologies used when electricity is generated. Whether it’s a wind power unit, a wind energy converter, or wind generator, they’re all the same.

One type of turbine is the HAWT which just stands for Horizontal-axis wind turbine. They are composed of the rotor shaft plus a generator which are both located on top of the tower, these are positioned to face into what wind there is. Larger turbines normally utilize a sensor along with what is called a servo motor. These usually contain a gearbox, and this helps the slow-speed rotating blades go faster which is more effective for powering the electric generator.

The turbines actually have to be pointing upwind if they’re going to create a substantial amount of power. However, it’s important to understand that these are extremely durable and they’re built to be safe. In fact, if you’re up-close and personal with one, you’ll notice the blades are built in front of the shaft so when turbulence hits or strong winds, it won’t collapse.

If you don’t have access to a HAWT, then the vertical-axis version (VAWTs) will be used. These are set up so the rotor shaft is in a vertical position. The benefit around this option is that the turbines don’t have to be situated against the wind in order to be efficient. Most people utilize this option when the wind tends to come from various directions throughout the day.

Unfortunately it’s extremely difficult to have the VAWTS mounted onto the high towers. So you’ll find these installed around the base of the tower.

When you see these towers, none of them are small. It is recommended that they be at least 100 feet high so they can get an increase in energy.

If you want to truly do your part and take advantage of a renewable resource, try combining it with home solar power as well. It will allow you to reduce your energy costs, help keep the environment cleaner, and let everyone around you breathe cleaner air.
