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!!

When does fission take place in power plant?

Fission takes place in a nuclear power plant continuously to generate heat by splitting uranium atoms in a controlled manner, producing energy. This heat is used to produce steam, which drives a turbine to generate electricity.


What energy transfer takes place when the steam what energy transfer takes place when the steam enters the turbine housing?

When steam enters a turbine housing, it undergoes a transfer of thermal energy into kinetic energy. This thermal energy causes the steam to expand and move rapidly, which in turn drives the turbine blades to rotate. The rotational motion of the turbine blades is then converted into mechanical energy that can be used to generate electricity or perform other types of work.


What energy conversion takes place in a nuclear power plant?

In a nuclear power plant, nuclear energy is converted into heat through a process called nuclear fission. The heat produced is used to generate steam, which in turn drives a turbine connected to a generator to produce electricity.


What energy conversions takes place when water boils resulting stream is blown against huge turbine blades the turbine blades spin in a magnetic field and the electricity is used to light a lamp?

The energy conversions that take place in this scenario are: 1) Thermal energy from boiling water is converted to kinetic energy when the steam is blown against the turbine blades, causing them to spin; 2) The kinetic energy of the spinning turbine blades is then converted to electrical energy as the blades interact with the magnetic field to generate electricity; 3) Finally, this electrical energy powers the lamp, converting it into light energy for illumination.


Part of power plant where fission takes place?

The part of a power plant where fission takes place is called the nuclear reactor. This is where nuclear reactions, such as fission, occur to generate heat that is used to produce electricity. This heat is then used to heat water and produce steam that drives a turbine connected to a generator.


What energy conversion takes place in a wind turbine?

In a wind turbine, the kinetic energy of the wind is converted into mechanical energy when the rotating blades spin the shaft of a generator. This mechanical energy is then converted into electrical energy by the generator.


Cellular energy takes place inside?

Cellular energy production takes place inside the mitochondria, which are organelles found in eukaryotic cells. The process by which cells generate energy is known as cellular respiration, involving the breakdown of glucose to produce ATP, the cell's main energy currency.


What energy transfer takes place when steam enters the turbin housing?

i believe it is chemical to kinetic but there is probably no transfer becasue chemical energy is stored energy like in a battery, but steam is i guess kinetic cuz its moving, and turbines definitely are kinetic due to movement, so probably no energy transfer.


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 transfer takes place when the turbine turns the generator?

Mechanical energy from the turbine is transferred to the generator, where it is converted into electrical energy. This process occurs through electromagnetic induction, where the motion of the turbine causes the magnetic field in the generator to change, inducing a flow of electric current.
