Wind power has become increasingly common worldwide over the last decades. The production cost of wind turbines has decreased and the technology has rapidly evolved.
Buying Energy Attribute Certificates (EACs) from wind power guarantees that the renewable energy consumed is from this source.
Wind power production is typically divided into two main categories; based Onshore or Offshore.
Building and running wind farms benefit the local area through the use of local suppliers, contractors and workers. Better infrastructure makes the area more accessible to visitors and may help boost tourism.
Norwegians have historically used wind power for automating agriculture, pumping water on sailing ships and producing electricity. One of the first offshore wind turbines was Norwegian. It was used to supply electric light on Fridtjof Nansen’s polar expedition ship, “Fram”, from 1893 to 1896.
In 2017, cumulative grid-connected wind capacity reached 515 GW (497 GW onshore wind and 18 GW offshore wind) and wind power accounted for almost 4% of global electricity generation.
Onshore wind capacity is expected to grow by 323 GW in the next five years and reach almost 839 GW by 2023 according to IEA’s Renewables 2018 forecast. China leads this growth followed the United States, Europe and India. As a result, onshore wind electricity generation would increase by nearly 65% globally over 2018-23.
Offshore wind is also expected to grow rapidly. Deploying turbines in the sea takes advantage of better wind resources than at land-based sites. In 2017, global offshore wind generation reached an estimated 55 TWh. By 2023, global offshore wind cumulative capacity is expected to reach 52 GW by 2023, up from 18 GW in 2017. Deployment will be led by the European Union and China (IEA).
