Does a wind turbine generate more energy than it takes to produce the turbine?

It depends on time and location.
If you place your windmill on top of a hill, it will be the most efficient. But as for your question, its down to the matter of time. How long is the windmill going to be running for?
If 2000Kw where used to produce a windmill.. and the windmill produced 1000Kw a year, it would make its effiency in 2 years. This is called pay back time!
Hope this helps!!

What energy transfer takes place when the turbine turns the generator?
kinetic energy is transfered to electric energy
What do you need to generate electricity?
It takes energy to generate electricity. Mechanical energy or thermal energy or nuclear energy , chemical energy,etc, etc,etc
What does energy payback time mean?
You need energy to make a solar panel. Put it on your roof and see how long it takes to generate that same amount of energy. That's the energy payback time.Energy payback time means the length of time that a solar panel (or other device) will take to produce that same amount of energy that was used to make it.This is used with renewable and non- renewable energy solutions to describe how long it takes for the device to generate the amount of energy that it took to make it in the first place. It can also be used to measure the amount of energy your save by using an energy efficient device.payback time = total costs/ total saving or money made or energy produced per year. You can thing of payback time in both economic and energy terms - how long it takes to pay back in money terms the costs, or thinking about the costs being the energy needed to produce the device.A wind turbine's energy payback time is about four months. The estimated life of a wind turbine is about 25 years.Devices like:solar panelswind turbineswater turbinesgeothermal power plantsbiofuel plantsbiomass power plantswave and tide power plants

What energy transfers takes place when the turbine turn the generator?
kinetic energy is transfered to electric energy
Is coal a renewable resource used for the generation of electricity?
Wind, solar and hydro are currently used to produce power. Hydroelectric being the most common and useful of the three methods.
What are the energy conversions which takes place in such power stations using fuels to generate electricity?
Chemical energy to thermal energy to mechanical energy to electrical energy
What are 3 alternative sources of energy?
Solar power Takes energy from phtons emmitted from the sun. Hydro power Takes power from currents of water turning a turbine. Nuclear power Splits atoms to release energy
What takes the most energy to generate microwave or ex ray?
An X ray takes more energy to generate because it is higher frequency (second in shortest wavelength only to gamma rays). Microwaves are just higher frequency radio waves.
Does nuclear energy change into electrical energy?
Obviously! It's the same phenomenon that takes place in a nuclear reactor. Radioactive elements such as uranium, thorium etc. are used as fuel to produce electrical energy. An enormous amount of heat is produced during the fission or fusion of these elements and this heat is used to rotate a huge turbine which produces electricity.
What energy changes takes place at the hydro electric power station?
Gravitational potential energy in the water is converted into mechanical energy by turning turbine "blades", the mechanical energy (kinetic energy) is converted to electrical energy by the electric generator.
What is the important functions that leaves perform?
Leaves are structures that takes the sun's energy to produce chemical energy
