Understanding of wind farms and wind turbines

What is a wind farm?

A wind farm or wind park, also called a wind power station or wind power plant, is a group of wind turbines in the same location used to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore.

Where do wind turbines work?

Wind turbines work best in open places where no obstacles block the wind. They are often part of larger wind farms which are often high up on hills or out at sea. Onshore wind is Scotland’s main source of renewable energy. In 2020 about 70% of electricity generated in Scotland came from onshore wind.

Are wind turbines a low-cost source of electricity?

The majority of turbines are installed on land. And land-based wind energy is one of the lowest-cost sources of electricity generation, as highlighted by the U.S. Department of Energy. Researchers at NREL are categorizing wind resources on land and advancing wind turbines to more efficiently generate electricity at even lower cost.

How much energy does a wind farm generate?

Each of these massive wind turbines is expected to generate 80GW annually, which could power about 20,000 European households and amount to savings of more than 38,000 tonnes of carbon dioxide per year. In comparison, the first wind farm in Denmark covered the annual power consumption of around 2,200 households. Size and distance matter

How big is a wind turbine?

Wind turbines used in offshore wind energy can be even larger than on land, with towers one-and-a-half-times the height of the Washington Monument and blades as long as a football field (as noted in to the U.S. Department of Energy’s list of 10 things you may not have known about wind energy).

What is distributed wind energy?

Researchers at NREL are categorizing wind resources on land and advancing wind turbines to more efficiently generate electricity at even lower cost. Distributed wind energy is a distributed energy resource, meaning it produces a smaller-scale unit of power.
