Wind power or wind energy is that the use of wind to supply the mechanical power through wind turbines to show electric generators and traditionally to try to to other work, like milling or pumping. Wind power may be a sustainable and renewable energy, and features a much smaller impact on the environment compared to burning fossil fuels.
Wind farms contain many individual wind turbines, which are connected to the electrical power transmission network. Onshore wind is a cheap source of electrical power, competitive with or in many places cheaper than coal or gas plants. Onshore wind farms even have an impression on the landscape, as typically they have to be cover more land than other power stations and wish to be built in wild and rural areas, which may cause "industrialization of the countryside"and habitat loss. Offshore wind is steadier and stronger than ashore and offshore farms have less visual impact, but construction and maintenance costs are higher. Small onshore wind farms can feed some energy into the grid or provide electrical power to isolated off-grid locations
