Another renewable energy type that is currently with very strong feasibility ratios and Investments trends is Wind Energy, due to more reduced investment costs and technology improvements.
Wind power is basically the passing of an air flow in the blades of a wind energy converter, normally called wind turbine generator, to provide the mechanical power to turn an electric generator. Wind power is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, consumes no water, and uses little land.
Wind Farms consist of many individual wind turbines, which are connected to the electric power transmission network. Onshore wind is an inexpensive source of electric power, now cheaper than coal or gas plants. Offshore wind is more predictable and have higher net equivalent hours than onshore, but construction, operation and maintenance costs are considerably higher.
Wind power gives variable power, which is very consistent from year to year but has significant variation every day, but weather forecasting and software can mitigate this situation. Power-management techniques such as having distributed Wind Farms, enough Pumped hydroelectric storage, dispatchable power plants, exporting and importing power to neighbouring areas, Energy Storage, or reducing demand when wind production is low, can in many cases overcome these intermittence problems.
