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. How do wind turbines work? How much electricity can a wind turbine create?
How efficient is wind power? See Resources. Ball Corporation is meeting half of its current U. What Is Wind Energy? Graph of cumulative U. 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. Types of Wind Turbines: Big and small turbines fall into two basic categories, based on the orientation of the rotor: horizontal-axis and vertical-axis turbines. Who Does Wind Turbine Maintenance? Rene Lopez, wind technician at Duke Energy Renewables Wind technicians are responsible for troubleshooting and repairing the electronics and mechanics that keep the blades spinning.
There are six basic considerations for wind energy projects: Wind availability and desired locations Environmental impact Community input and local need for renewable energy generation Favorable policies at the state and federal levels Land availability Ability to connect to the power grid Just like commercial solar PV projects, permits must also be secured before a wind power installation is started.

Types of Wind Turbines The majority of wind turbines fall into two basic types:. Horizontal-Axis Turbines. Horizontal-axis wind turbines are what many people picture when thinking of wind turbines. Vertical-Axis Turbines. Mike vanBavel Applications of Wind Turbines Modern wind turbines can be categorized by where they are installed and how they are connected to the grid:. Land-Based Wind. Land-based wind turbines range in size from kilowatts to as large as several megawatts.
Offshore Wind. Offshore wind turbines tend to be massive, and taller than the Statue of Liberty. These turbines are able to capture powerful ocean winds and generate vast amounts of energy. Distributed Wind. Primus WindPower Learn More. Click on the video for an animation showing how wind turbines generate electricity. On top of each wind turbine is a box known as a nacelle.
Attached to the nacelle are three propeller-like blades that connect to a rotor. Also on the nacelle is an anemometer to measure wind speed and direction. Click here for an inside view of a wind turbine.
