Introduction
Wind energy is one of the cleanest, most abundant forms of renewable energy available. It's also a cost-competitive form of power generation that can be used to meet electricity demand at times of peak demand. While wind turbines are becoming more and more common in residential areas, there are still some misconceptions about how they work and what factors affect their performance. This article will explain the basics behind wind turbines so you can make an informed decision about whether or not wind power makes sense for your home or business.
How does a wind turbine generate electricity?
A wind turbine is a device that converts the kinetic energy in wind into mechanical energy. The mechanical energy is converted into electrical power by a generator, which is connected to the rotor by a shaft. The rotor turns the blades, which capture the wind and convert it into rotational motion that drives an alternator (the heart of your home's electrical system) or generator(s).
The electrical output generated by these turbines can be stored in batteries or sold back to utilities as renewable energy credits (RECs).
Wind Power Resource Potential
Wind power is a renewable energy source, meaning that it does not produce pollution or greenhouse gases. It's also clean and safe—no emissions are created when turbines turn the wind into electricity. In fact, wind turbines can be placed in areas with no previous history of wind turbines because they don't pollute the environment like other types of generators do.
Wind power has been growing rapidly around the world as countries realize how much renewable energy could help them meet their energy needs while protecting our air quality and climate change efforts. The United States has some of the best wind resources in North America; if you live near an area with high levels of winds such as Iowa or Texas then it's likely there will be plenty of opportunities for installing new turbines at your home!
How Do Wind Turbines Work?
Wind turbines are a type of wind energy conversion device that uses rotating blades to convert wind into mechanical power. Wind turbines are used to generate electricity on large and small scales, including in industrial applications such as oil drilling platforms and offshore platforms.
Wind turbines use wind energy to produce mechanical power which can be used to produce electricity in many ways:
- Onshore - A wind turbine is mounted on top of an existing building or tower, usually with its blades pointing into the wind; this configuration is called "on-shore" because it operates within sight of land (see below). These types of turbines are often found near coastal areas where there's plenty of natural winds coming ashore from oceans or seaside locations such as islands off coastlines where no trees or buildings obstruct their path .

What Is a Wind Turbine?
A wind turbine is a device that converts the energy in wind into mechanical or electrical energy. The wind turns the blades, which spin a shaft connected to a generator. The generator produces electricity, which powers your home or business.
Wind turbines are mounted on towers to catch the wind and use it for power generation.
How Do Wind Turbines Produce Electricity?
How do wind turbines produce electricity?
The wind turbine uses the kinetic energy of the wind to turn a propeller, which generates mechanical energy. This mechanical energy is then converted into electrical power by a generator. The generator's rotation converts this mechanical energy into an electrical current that flows to your home via wires connected to it.
Parts of a Horizontal Axis Wind Turbine
- Blades
- Hub
- Nacelle (power unit)
- Rotor (rotating or stationary)
The tower is where the blades and nacelle meet. The rotor assembly sits inside this hub area, which houses a yaw drive system that rotates in opposite directions to turn wind turbine blades.
Parts of a Vertical Axis Wind Turbine
A vertical axis wind turbine (VAWT) has a shaft that rotates around its own axis, with the blades attached to the end. The generator is located inside of the nacelle, which houses all other components including wires, bearings and seals.
The yaw drive system of a VAWT consists of two main parts: an electric motor that turns a gearbox connected to each rotor blade; and an armature (generator). The armature generates electricity by spinning at high speeds inside of it's own housing without touching any other part outside its casing. This allows for much greater efficiency than would otherwise be possible if all power was transferred through mechanical connections between individual parts such as gears or bearings on different components within your machine's structure
What Makes a Good Wind Site?
A good wind site is one where the wind speed and direction are favorable, the topography provides a suitable surface for turbines to be installed, solar radiation is high enough to power them, and geology protects them from damage. It's also important that there are no obstacles between the turbine blades and their surroundings (such as trees or houses).
Wind shear may be an issue at some sites because its effects can affect how well a turbine operates. Wind shear occurs when wind speeds change rapidly—from very low to very high in less than 30 seconds—and causes turbulence around objects such as buildings or trees.
How is the Energy in the Wind Converted to Electricity in the Generator?
The energy from wind turbines is converted into electricity in a generator. A rotor hub connects to the generator, which converts mechanical energy from the wind into electrical energy. In order for this to happen, there must be an appropriate amount of space around it so that air can pass through easily and efficiently.
The following diagram shows how this system works:
There are many factors that go into whether wind energy makes sense for you.
There are many factors that go into whether wind energy makes sense for you. These include:
- Your particular neighborhood, which can have a significant impact on the amount of electricity that your turbine will produce. For example, if you live near a large body of water or other obstructions that block the wind's path, it may be more challenging to get good results from your turbine than if you lived somewhere with less powerful winds and more open space.
- The size of your property and how much space there is between buildings or trees stands in relation to its distance from power lines; this could affect how much power is available at any given time (and therefore affect what kind of turbine would work best). Similarly, if there are tall trees between where the electricity comes into use then those trees could block some part(s) but allow others through easily enough so long as there's enough room around them both above ground level as well as below ground level where wires come out from poles connected together via underwater cables running beneath ground level along roads/streets etc...
