A wind power turbine is used to convert kinetic energy from the wind to mechanical energy such as electricity. The amount of electricity generated from the wind is basically dependent on the size and make up of wind power turbine.
Large wind power turbine is designed to generate more than 100 megawatts of electricity and several pieces are installed in windfarms where clusters of wind power turbine installations provide power to a community.
Wind power turbine that are small in sizes and capable of producing smaller amounts of electricity, about a hundred kilowatts, are used to generate electrcity for homes, small businesses and farms. Smaller versions of wind power turbine which can produce 20 to 500 watts of electricity are very useful in charging batteries for use in electrical appliances and sailboats. Electricity generated from the wind may be used as the sole source of electricity, back-up electricity, or in combination with the use of utility power to reduce amount being paid to electric companies. This is how most homes start, augmenting wind power turbine output with electricity from the grid.
Wind Power Turbine Types:
The two types of wind power turbine installations are the wind power turbine with horizontal axis and wind power turbine with vertical axis. The more common type is the horizontal axis wind power turbine comes with a tailvane that is continuously pointing at the direction of the wind and therefore should be mounted directly aiming the wind. The vertical axis wind power turbine works whatever direction the wind comes from but must be installed in a larger ground space so that supports may be installed for the guy wires.
Small Wind Power Turbine
Small wind power turbine are used in a wide range of applications such as in residences (on-grid or off-grid), offshore platforms, rural schools, telecom towers, remote monitoring and other uses that needs electricity but the location has o electric grid or the unstable supply of electricity.
• Air Breeze Land 12Volt 200Watt Wind Turbine – is made of heavy-duty composite blades and is equipped with a microprocessor-based smart internal regulator that can track peak power. Power generated can be used to run home appliances such as washing machine, television, refrigerators, lights, and radio.
• Southwest Windpower Land Air X 12Volt 400Watt Wind Turbine – the composite blades are made from carbon fiber with castings of aluminum alloy, with internal battery charge regulator, and its best feature is the patented auto-brake that can slow down the blades to spin silently when the charging the batteries. Common applications include: telecom towers, remote cabins, monitoring stations, and for home appliances such as radio, lights, and television.
Large Wind Power Turbine
• SOMA 24Volt 1000W Wind Generator – is designed to provide electrical power to homes in remote areas. It can power lighting for the homes as well as home appliances such as water pump, television, radio, kitchen blenders, washing machine, refrigerators, and power tools. It is also ideal for telecom towers and research base stations due to its no maintenance feature and rugged durability.
• Proven 2.5 48Volt 2500Watt Wind Turbine with 6.5m Tower Kit – is designed with Proven Energy Flexible Blade System that allows wind power generation in strong wind or light wind conditions. The power it generates is enough to meet the electricity needs for a standard home with three bedrooms, not including the heating requirements. The explosion-proof feature of this wind power turbine makes it ideal for use in off-shore oil platform.
The wind can be effectively harnessed for electricity as proven by the use of wind power turbine installations. Technology for renewable energy, particularly wind, solar and water are being developed on many fronts. Homes, communities and cities will soon have these options available to them on a more mainstream scale.
Ever wondered if it was possible to measure the power of the wind? Well it is and I'll show you how.
I've just added a really good page here all about measuring the power of the wind, it's entitled wind turbine efficiency and discusses ways in which it is possible to measure the strength and power of the wind.
By measuring the power of the wind it is then easy to determine whether a wind turbine is being efficient in its present position or not. Also whether there is enough wind over a period of time to make having more turbines in that same area a real benefit.
I show you a quick equation that can be used to calculate these facts .
