How many windmills does it take to make the same ammount of energy as a nuclear power plant?
It is dependent on the size of the generator or turbine attached to the windmill. For example, Home Depot sells a home version that outputs 900 watts or 60 amps (in ideal conditions). The largest wind turbines can generate up to 7 megawatts!
How do wind mills work?
Windmills use blades to gather wind that flows over it. Just like an airplane uses wings for lift, windmills use their blades for lift as well - in this case to turn the windmill. Windmills are pretty simple structures; their blades are connected to a drive shaft that is connected to an electric generator. As the blades turn, this turns the drive shaft and creates electricity. Electricity is sent through wires and collected.There are several different types of windmills, categorized by the direction in which their blades rotate. Two different types of windmills, most commonly called turbines when producing energy, are the horizontal axis turbines and the vertical axis turbines. Horizontal turbines are by far the most popular type of turbine and are the traditional type of windmill with blades that are similar to an airplane's propeller. These are the windmills we often see pictures of - the Holland variety. On the other hand, vertical axis windmills have blades that resemble an egg beater. They are far less popular than horizontal windmills only making up a very small overall percentage.In addition, wind mills can be used to harness energy without producing electricity. An example is the type of windmill that takes the mechanical motion induced by the blades to turn millstones that grind corn and other grains, hence the term "windmill". Other examples of non-electrical windmills include those that pump water. (These have been around for a long time.)
How can geothermal energy be converted to electrical energy?
The same way that burning fossil fuel is used to produce steam to turn an electrical generator. Geothermal heat from far beneath the ground is captured and used to turn a dynamo or turbine to generate electricity.
What are the disadvantages of wind power?
Disadvantages of wind power:The strength of the wind is not constant and it varies from zero to storm force. This means that wind turbines do not produce the same amount of electricity all the time. Luckily, wind energy isn't produced in isolation. It's added to widely connected energy grids with 24 hour spot energy markets. It's added to grids that span thousands of kilometres and have many types of generation and demand. Up to about 20% of a grid's generation capacity, it requires very little backup.Some people see large wind turbines as unsightly structures and not pleasant or interesting to look at. They believe that wind turbines degrade the landscape.Wind turbines generate noise. A subset of people who live near wind turbines find this noise annoying. A subset of those people get stressed by it. Wind turbine noise does not make people sick.Birds are killed by wind turbines. Studies show that wind turbines do not threaten the vast majority of bird species populations. Killing birds, in other words, does not threaten birds generally. That said, wind turbines should not be sited on raptor migration routes, as the Altamont wind turbine farm was. The best evidence is that song birds migrate at 2000-4000 feet, far above wind turbines and sea birds avoid them according to radar and thermal studies of North Sea wind farms.Bats are also killed by wind turbines, due to barotraumic stress (the reduced air pressure behind a wind turbine blade is damaging to bat's lungs and heart). However, bats are not killed in significant numbers compared to their populations by wind turbines. Bats are, however, killed in significant numbers in North America by white nose syndrome (300,000 in one cave alone.)
What was the wind speed in the philadelphia Mississippi tornado?
If you mean the one from April 27, 2011, the wind speed for that tornado was estimated at 205 mph (330 km/h), qualifying it as an EF5. Some have suggested, however, that the severe ground scouring caused by this tornado indicates winds far higher than 205 mph.
What is the differeance between upwind and downwind turbines?
An Upwind turbine faces into the wind with the turbine blades in front of the Nacelle* while a Downwind turbine has blades to the rear of the Nacelle and faces away from the wind. Up-wind turbines are by far and away the most common, but down-wind turbines (usually two-bladed) are also used in certain situations.In very strong winds the turbine blades of a wind turbine generator flex under enormous forces. With a down-wind turbine the blades flex AWAY from the mast which prevents them from crashing into it. Up-wind turbines need to be designed so that the blades are positioned at a good distance from the mast, and they must also be engineered to be inflexible (which costs more money). In addition, when the blades of a down-wind turbine bend it reduces the stresses on the mast as wind energy is lost in bending the blades. Finally, down-wind turbines do not need a tail (or motorised yaw mechanism) to align them with wind as the turbine blades perform this task (although this can also be a serious disadvantage in large down-wind turbines if wires carrying huge currents are getting twisted).Down-wind turbines on the other hand are generally noisier (additional aerodynamic noise), and the blades are subject to more forces than those of up-wind turbines. Another serious disadvantage of a down-wind turbine is wind shadow behind the mast causing a drop in power each time a blade passed behind the mast.*Nacelle = is located at the top of the mast and contains the rotor and generator, and sometimes a gearbox. Basically it is everything except the turbine blades, tail, and mast.
Can wind turbines be used to produce a lot of energy?
The energy created from a wind turbine is proportional to the formula for area of a circle which is pi x r^2. pi = 3.14159, and r=radius. this means that if the blades are twice the length of another wind turbine, there is a far greater amount of energy produced. Information courtesy of Centre for Alternative Technology, Wales. In general, wind turbines are a great way to go if there is sufficient wind as the energy is sustainable energy whereas other means such as coal burning are finite
How far from property line a wind turbine should be?
You need to check your local and state laws for the answer in your jurisdiction.
Which is better diesel technician or wind turbine technician for a career here in southern California?
Well wind turbine techs and diesel techs make like the same amount 44000 but wind turbine techs have to travel or be far from home alot but can save alot of extra per diem cash if they want like a truck driver
How much is a yearly plan for a wind turbine?
Far more than the cost of installation, upkeep and savings made.
How much does wind energy cost?
So far it is free because wind is a renewable energy source but you have to count the turbine and generator and everything that produces the electricity.
How long do wind turbines last for?
The turbine companies generally claim 20 to 25 years. Recent studies have shown that the life span is probably more likely to be around 10 to 12 years. This is due to the electronics within the turbine itself. Most electronics are build to last for 10 years as after this time it is thought they will be obsolete (which in most cases is probably true). The wind turbines electronics are no different, while the blades and outside may well be build to last for a far longer time, the components are build to standard electronic component levels and are generally not build to last longer than the average 10 years (that's not to say that in some cases they wont though). So there is a fair possibility that after 10 or so years the complete inside of a wind turbine will need replaced, effectively meaning the whole wind turbine will need replaced.
How far from property line a wind turbine should be installed?
Different places have different regulations. Check your local (country/state) planning laws and building regulations.
What is the future for wind resource?
Wind power is the fastest growing energy resource on the planet Earth. There is no such thing as an electric powered jet engine, or rocket engine, however, wind power can supply the power to items that get their energy from electricity, so wind power (which does not run all the time except at high altitudes), is being built all over the planet Earth. It will last forever, and wind power does not pollute the air it uses. You can breathe the air that goes through the blades of a wind turbine. Just do not stand too close to a wind turbine. Wind power is Not perfect, but, there is No perfect energy source. Almost every country on the Earth can use wind energy, so it has a very green and bright future. Wind power turbines are being built all over the place and in ever greater numbers. The number of birds and bats killed by wind turbines, is far less than birds or bats killed by other energy sources, such as coal, oil, or natural gas.

It is dependent on the size of the generator or turbine attached to the windmill. For example, Home Depot sells a home version that outputs 900 watts or 60 amps (in ideal conditions). The largest wind turbines can generate up to 7 megawatts!
How can people get tossed back on the ground by a tornado?
A wind greater than 90 mph can lift a person off the ground. If a person gets tossed out of the wind field they simply fall back to the ground. Some, whole do not have far to fall, have escaped without serious injury.
