Own Your Energy With The Wind Turbine
It is certainly a time for concern, and a time to realize that we all need to start taking action before it is too late. We can take action in two ways: we can be conscious of how much energy and water we are using at home, and we can learn how to generate our own electricity using cost-effective methods that are also pollution-free. The two most efficient ways of generating your own electricity are to use solar power or wind power -- or both -- and these methods can be used to replace the electricity supplied to you by the power company. With solar power and Wind turbine for your home, there are several worries that are eliminated from your life. When you generate your own power, your electricity bill will be much lower (and sometimes even eliminated entirely), you will be better-placed to withstand power blackouts, and you will also be helping the environment.Wind power works best in the following situations:You should ideally have access to a reasonably-sized area of land; an acre or so is a typical size.You really need a reasonably windy location: 11 miles an hour average is good. If the average wind speed is much lower than that then you may not generate enough electricity to make it worthwhile, so make sure the wind speed is high enough. If you live near the coast then the weather tends tends to be fairly windy and so a short tower will suffice. But in a low-wind area you may find that you need a taller tower to catch the winds blowing at higher altitudes. The devices in your home need to rely on an uninterrupted power supply. Fighting power interruptions is a piece of cake with your own Wind turbine and the associated batteries, and you will not need to be afraid of your power supply suddenly being interrupted and your work having to stop.A wind generator is usually made up of a hub holding five turbine blades, sitting atop a tower or pole. When the wind blows, the blades turn around the hub, and electricity is made using a dynamo in the hub. The height of the tower supporting the wind generator depends on your local situation. The electricity generated by your wind turbine can be used directly, or it can be stored in a battery for later use -- thus making such a set-up very efficient.
