How the Wind Turbines Operate to Generate Power

You ever see those large windmills out on the countryside or on television, then sit there and wonder how they work? The easiest way to explain it is that they have blades which are connected to a shaft. Once the shaft is able to turn the generator, then the power gets produced. Obviously it’s not as easy as it sounds, but we’ll help you understand it a little better.

The wind turbine is just a machine that uses rotation to convert the energy of the wind to a mechanical form of energy. When this type of energy is used directly by a machine to do tasks such as grinding or pumping, this machine is generally thought of as a windmill. But when this mechanical energy is changed to electricity, then this machine is thought of and either a WPU (wind power unit), wind generator, or a WEC (wind energy converter).

Probably the most popular is the horizontal-axis wind turbine, commonly referred to as the HAWT. These have a rotor shaft and generator which are located at the top of the tower. In order to get the most benefit out of it, they have to face into the wind. When you get into the bigger versions they’ll have sensors to go along with a servo motor. In short, it allows these machines to produce more energy by rotating the blades at a quicker pace.

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.

It is quite hard for get these vertical-axis turbines to be mounted onto the towers. This means that they are most of the times installed more toward the base of where they sit, as in a roof of a building or the ground.

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.

In the end you just have to want to do your part for the environment and our world today. Plus, it also helps save you money while cutting down on your energy costs. What better way to do it then with a renewable resource that will never be depleted. It’s the wave of the future and getting back to the basics as best we can.
