Wind Power

435000 megawatts.

Early uses of wind energy was generally for direct mechanical actions such as grinding or pumping. Hence the term windmill to indicate a wind powered mill.

However, virtually all modern windmills generate electricity.

It is likely that most future windmills will also be coupled to electricity production.

It is unlikely that wind energy will become the only energy source available, in part because of its somewhat unpredictability and tendency to have variations of power levels not connected to grid requirements.

There would be benefits of connecting wind energy to energy sources like hydroelectric power generation. When the wind is blowing, there would be less need for hydroelectric, and the water could be stored to some extent like a giant battery. When the wind stops, the hydroelectric energy would be used.

Another form that it could be coupled to is automobile charging... it is a little tricky because of the irregular nature of the wind energy, but perhaps by either charging a secondary battery bank, or counting on a strong nocturnal breeze it would work. Some people have suggested that auto batteries wouldn't actually need to always be "topped off", but rather they could be used to some extent as a reservoir to ameliorate peak energy uses.

Hydrogen is a form of electric energy storage that wouldn't necessarily need continuous inputs, and may someday be used in conjunction with automobile fuels.

Well, its kind of obvisus to build one on a windy place for example: a hill, and some are built in the the sea. So mostly places where it is quite winddy, or where wind is likely to be.

wind turbines.

Because the Wind is not always blowing. Wind is off and on, we need power that we know will be there when we need it such as coal. But Wind Power is still great and it is "green."

Wind is one of our free resources and in some areas blows up to 80% of the time. The wind is used to move large propeller blades attached to a gearbox. The gearbox is connected to a turbine to produce the electrical current. The gearbox also prevents the propeller blades from going into a runaway mode.

A wind turbine, which is installed on top of a tall tower, collects kinetic energy from the wind and converts it to electricity that is compatible with a home's electrical system.In a normal residential application, a home is served simultaneously by the wind turbine and a local utility. If the wind speeds are below the wind turbine's start up speed there will be no output from the turbine and all of the needed power is purchased from the utility. As wind speeds increase, turbine output increases and the amount of power purchased from the utility is proportionately decreased. When the turbine produces more power than the house needs, the extra electricity is sold to the utility (net metering). All of this is done automatically.

The number of wind turbines needed would depend on various factors such as the size and capacity of the power plant, the efficiency of the turbines, and the local wind conditions. In general, it would likely require a significant number of turbines to match the electricity output of a power plant.

The average size of a windmill blade ranges from 35 to 45 meters (115 to 148 feet) in length.

Turbine blades are shaped like a fan to efficiently capture wind or water energy and convert it into rotational motion. The curved shape helps the blades harness more energy from the flow of fluid, increasing efficiency and power output.

Over time, yes, the cost of the installation and ongoing maintenance of a Wind Power Turbine can be recovered from the sale of the electricity produced. However, the length of time required is dependent on the location (available wind) and the price you receive for the power generated.

Most commercial turbines being assembled onshore in Sweden today (2012) have blades that are about 50 meters long.

Offshore turbines have blades up to 70 meters.

An 83 meter blade was sent to a testing facility in October of 2012.

Both wind energy and fossil fuels can be used to generate electricity. However, wind energy is a renewable resource that relies on the natural movement of air currents, whereas fossil fuels are non-renewable resources that come from the remains of ancient plants and animals. Both sources have environmental impacts, but wind energy generally has a lower impact in terms of greenhouse gas emissions and pollution compared to fossil fuels.

Most do, although some systems are mounted vertically and rotate around their mast. These systems have no need to move into the wind.

If you have the book, look on page 130. There is a great description of her on that page.

wind turbines are placed to make use of wind energy, in the wind turbine an alternator having large gear mechanism is fixed , when the wind blows, the turbine moves, which in turn forces the gears to rotate, which in turn moves the alternator to generate electricity.

No, unless fossil fuel energy is used in their construction. In that case, wind turbines generate the amount energy required to make them within 6-12 months. That's the fastest of any type of energy - It takes a fossil fuel turbine about 2 years to generate the same amount of energy involved with it's construction.

Wind systems also consume fossil fuels when the wind is above the safe operation limit by placing power on the generators to prevent the blades from turning. They also consume power for a few minutes while starting to get the blades to the correct speed and sync with the grid. Despite these consumptions, wind is still a net provider of energy and they generate much more than they consume.

Well there both two power sources that are renueable.... There both good......

A 1.5 MW turbine is 80ms in height.

A 3MW turbine is 90m in height.

The world's largest-capacity turbine, the Enercon (7.58MW) is 198m in height.

Wind energy can be stored in a variety of ways. One common method is by using batteries to store excess energy generated by wind turbines when the demand for electricity is low. Another method is through pumped-storage hydropower, where excess wind energy is used to pump water to a higher elevation, and then the water is released to generate electricity when more power is needed. Additionally, some wind farms are connected to the electrical grid and feed their excess energy back into the system for use by others.

A small wind energy system can be used to augment your utility source to power appliances, lighting, and heat. These stand alone systems can be appropriate for homes or farms and can help you get on your way towards energy independence.

You have to go to your local government office, and obtain a permit. You then must secure the proper person with the right training to install the wind turbine on your property so they can make sure it is safely done.
