For example, they are cheaper to produce and can mount on rooftops. They’re not as efficient as horizontal-axis turbines, but they have a few advantages that make them a good option for some applications. These turbines are more common in commercial and industrial settings. The most popular type of vertical-axis turbine is the Darrieus turbine. Vertical-axis turbines have blades that spin around a vertical shaft. Two-blade turbines are less efficient but are cheaper, and four-blade turbines are even less efficient but are even more affordable. They’re also the most efficient type of horizontal-axis turbine, but you have to pay a tidy sum to get a decent one. These are the types of turbines you usually see in people’s homes. The most popular type of horizontal-axis turbine is the three-blade turbine. Horizontal-axis turbines have blades that spin around a horizontal shaft. Horizontal turbines are usually used in residential applications, while vertical ones are more common in commercial and industrial settings. There are two main types of small wind turbines: horizontal-axis and vertical-axis turbines. What Are the Main Types of Small Wind Turbines? So, if you use 10,000 kilowatt-hours of electricity per year, you’ll need to generate at least 5-kilowatt-hours per year. Typically you’ll need a turbine that can produce about 50% of your home’s energy needs. Small wind turbines for your home can range from 400 watts to 10 kilowatts. If you use less electricity than this, you can get by with a smaller turbine. This figure assumes that you have an electric water heater, dryer, and an air conditioner. The average home uses about 10,000 kilowatt-hours of electricity per year. But if the wind is blowing at 30 miles per hour, that same turbine will produce about 9 kilowatt-hours of electricity that day. The amount of electricity a small wind turbine can produce depends on the amount of wind it receives.įor example, if the wind is blowing at 10 miles per hour, a 400-watt turbine will make about 1 kilowatt-hour of electricity in a day. This spin turns a generator, which produces electricity that you can use to power your home. The blades on the turbine catch the wind, and the rotor spins. Small wind turbines work by converting the wind’s kinetic energy into electrical current. This article covers the benefits and drawbacks of using a small wind turbine and what you need to know before buying one. You should be aware of both the advantages and disadvantages of these turbines. Small wind turbines are a great way to reduce your reliance on the grid, and they’re becoming more popular as people become aware of their benefits. If you seek to save money or play a part in solving the world’s energy crisis, a wind turbine for your home is an excellent idea.īut before you buy one, there are a few things you need to know.
