2.1 Offshore wind energy Offshore wind energy can be defined as the energy generated from the wind at sea. Wind is produced by uneven heating of the earth’s surface by the sun. A wind energy turbine can convert the kinetic energy of the wind into mechanical or electrical energy that can...
Wind Turbines Wind turbine is a machine that converts the wind's kinetic energy into rotary mechanical energy, which is then used to do work. In more advanced models, the rotational energy is converted into electricity by using a generator. The most familiar forms of wind turbines are the ho...
Wind turbine for converting kinetic energy of wind flow into electrical energy, has wing projection, where flow at projection is divided into unbraked air flow and another airflow so that annular turbulence is produced at rear edge The turbine (1) has a stator ring (32) received by a stator...
A approximate graph of the relationship between wind speed and energy generated by a wind turbine is presented below. A wind turbine will produce the highest electrical energy when the wind speed is around 15-17 metres Wind turbine rotors (see definition below) are also designed to turn (as w...
Some alternative energy sources are: biomass energy, geothermal energy, hydroelectric power, solar power, wind power, fuel cells, ocean thermal energy conversion, tidal energy, and wave energy. C Biomass is renewable energy that is produced from organic matter. Biomass fuels include wood, forest ...
The speed of the wind and the size of the blades determine how much energy can be produced. Wind energy is more efficient in windier parts of the country. Most wind power is produced from wind farms — large groups of turbines located in consistently windy locations. Wind, used as a ...
Additionally, the turbine has a high electric power output, a good self-starting characteristic, and low starting and cut-in wind speeds of 2.25m/s and 2.75m/s respectively. It also benefits from a simple mechanical structure and can therefore be produced cheaply. 展开 ...
A wind turbine is a device for converting thekinetic energyin wind into the mechanical energy of a rotating shaft. Usually that rotating mechanical energy is converted immediately by a generator into electrical energy. In the large turbines, such as those shown in the picture above, there is ge...

Unlike power plants, many wind plants are not owned by public utility companies. Instead they are owned and operated by business people who sell the electricity produced on the wind farm to electric utilities. These private companies are known as Independent Power Producers. ...
