Vertical-axis wind turbines come in several varieties, including the eggbeater-style Darrieus model, named after its French inventor. Wind turbines can be built on land or offshore in large bodies of water like oceans and lakes. The U. Department of Energy is currently funding projects to facilitate offshore wind deployment in U. Modern wind turbines can be categorized by where they are installed and how they are connected to the grid:.
Larger wind turbines are more cost effective and are grouped together into wind plants, which provide bulk power to the electrical grid. They do not have the same transportation challenges of land-based wind installations, as the large components can be transported on ships instead of on roads.
When wind turbines of any size are installed on the "customer" side of the electric meter, or are installed at or near the place where the energy they produce will be used, they're called "distributed wind. Many turbines used in distributed applications are small wind turbines.
Single small wind turbines—below kilowatts—are typically used for residential, agricultural, and small commercial and industrial applications. Small turbines can be used in hybrid energy systems with other distributed energy resources, such as microgrids powered by diesel generators, batteries, and photovoltaics.
These systems are called hybrid wind systems and are typically used in remote, off-grid locations where a connection to the utility grid is not available and are becoming more common in grid-connected applications for resiliency.
Learn more about distributed wind from the Distributed Wind Animation or read about what the Wind Energy Technologies Office is doing to support the deployment of distributed wind systems for homes, businesses, farms, and community wind projects.

The Advantages of Wind Energy: Wind turbines typically repay the lifetime carbon emissions associated with their deployment in less than a year, before providing up to 30 years of virtually carbon-free electricity generation. Wind energy helps reduce carbon dioxide emissions — in , it avoided million metric tons of C02 emissions.
Wind energy provides tax revenue to communities that host projects. The wind industry supports job creation, especially during construction. The industry supported , jobs across the U. A diagram showing components of a standard wind turbine Power is generated through rotating wind turbines that harness the kinetic energy of moving air, which is converted into electricity. Most wind turbines have four basic parts: Blades are attached to a hub, which spins as the blades turn.
The blades and hub together make the rotor. The nacelle houses the gearbox, generator and electrical components. A foundation holds the turbine in place on the ground. This demonstrates just how fast wind power capacity in the UK is growing. There are roughly 8, onshore wind turbines and 2, offshore turbines in the UK. Go to RenewableUK for the latest statistics. Altogether, they produce enough power to meet the annual electricity demand of around 12 million homes [ 1 ]. At Good Energy, we have two windfarms that together produce enough electricity to power almost 12, average UK homes.
We also buy power from independent renewable generators, many of whom generate electricity using wind power. The towers are normally made of steel but the blades can be manufactured from glass fibre or reinforced polyester that need to be strong yet light enough to turn in the wind.
A single 1. The Whitelee Wind Farm in Scotland has turbines that provide electricity for around , homes. Enter your postcode to compare quotes from leading professionals. Privacy Policy. The core component of a wind turbine is the generator which converts mechanical energy into electricity. So the wind provides the movement and torque and the generator does the rest. For an industrial scale turbine, like the ones you see on wind farms, there will normally be an anemometer that is attached to a control panel.
