Getting to Know Wind Turbines
Tuesday, September 29th, 2009If you are one of those people who doesn’t have a clue when it comes to how electricity is generated, then this information is for you. Electricity comes in many forms and there are many sources of electricity also. Starting to become the most popular source of electricity is the wind. Wind is a very clean form to produce mechanical power, which is a key factor for generating electricity.
How we can get wind to work for us is creating a wind turbine that functions opposite of the way a household fan works. Household fans use electricity to generate wind, and a wind turbine uses wind to make electricity. A standard wind turbine consists of the generator, shaft and blade, which is all strategically placed to catch the wind that will then turn the blade. The turning of the blades triggered the shaft and once this continuous action begins, started by the wind, the generator, which is connected to the shaft will produce electricity. This electricity can give out the same quality of electrical power as the electricity found from other sources.
There are two classifications of wind turbines, the horizontal axis design and the vertical axis design. The horizontal wind turbine has three blades and functions best when directly facing the wind. On the other hand, the vertical wind turbine is designed like an egg-beater, invented by a French man named Darrieus. Farmers or rural homesteads with a good amount of land, found out how to bring in another source of income, by leasing their land to power developers. Since then, wind farms have cropped up all throughout the Midwest and in the West.
Designs is not the only variation for the wind turbines, there size is also a factor. There are really large wind turbines, those are the ones you’ll see at a wind farm, and they serve as the primary source of electricity in the electrical grid by producing a few megawatts. The smaller turbines usually produce lower than 100 kilowatts of electricity and are most often found in the residential areas. They are good for water pumping needs and other small tasks.
To find out more about the efficacy of a wind turbine, go to your local utilities website and there you will find just how wind is changing things for the better.
