Since 1890, Denmark has used wind energy for power generation. More than 100 years later, wind power generation has become the most popular way of wind energy utilization.
Wind power generation uses the wind to drive the wind turbine blades to rotate, and then increases the rotation speed through the booster engine to drive the generator to generate electricity. Wind power generation does not need fuel, will not produce pollution, and is inexhaustible. It is very suitable for areas with high wind speed all year round and coastal waters, as well as coastal islands, grassland and pastoral areas, mountainous areas and plateau areas with water shortage, fuel shortage and inconvenient transportation.
Wind power plants can be built in areas with strong wind all year round on land. However, since the wind will consume its energy when encountering obstacles, it is best to build them in open areas, but not near the airport, otherwise flight safety will be affected. Of course, it is easier to build a plant on land. However, due to the vigorous development of wind power generation in various countries, there are fewer and fewer places suitable for building wind power plants on land, so people move the plant to the sea. Therefore, at present, the development of large-scale wind power plants is mostly offshore. For example, Britain, Denmark, Sweden and Germany have established offshore wind power plants. Offshore wind power plants do not occupy valuable land, and the terrain is open, which is its advantage. However, compared with land-based wind power plants, offshore wind power plants have high cost, equipment is easy to be corroded, and the cost of maintenance and repair is also high.
Therefore, it is better to build power plants on the sea or on land, which can not be generalized. We should adjust measures to local conditions.
