In order to collect enough energy from the wind to make any generator practical, the turbine (or propeller) needs to be pretty good sized. You can see this for yourself at any of the wind farms currently operating; typically, the turbine itself is at least 100 feet in diameter. Propellers are limited in their speed by how fast the tip of the blades travel through the air. If the tip starts to get close to the speed of sound, the blade's efficiency drops dramatically, added with the chance of mechanical damage from the severe buffetting that's encountered. Thus, we regulate the blade's speed to stay below this point by changing the angle of the blades through the use of a governor. Conversely, most generators available nowadays are built as small as possible to keep overall weight and rotating mass at a minimum. Also, the more iron in the core, the more energy is lost through heat. Therefore, to get the expected amount of energy from these requires a relatively high rpm as compared to what's being produced by the propeller on our windmill. Therefore, to be able to mate the two together, we have to increase the propeller's rpm of, say, 30 rpm, up to where the generator needs to be, which can run any where from 1800 rpm to over 3600 or more.

What else can I help you with?
How is hydroelectricity gathered?
The water runs through turbines and, this mechanical energy is transfered to generator which inturn is transfered into electricity for homes, businesses, and other things that need electricity.
How is it possible to generate electricity without a battery?
Electricity can be generated without a battery using methods such as solar panels, wind turbines, hydroelectric power plants, or thermoelectric generators. These methods harness natural resources like sunlight, wind, water, or heat to produce electricity directly, without the need for a battery to store the generated power.
How do hydroelectric energy plants work?
Hydroelectric plants use the running water by a turbine with blades on it, and when the water flows through these turbines they rotate,. in turn rotating the alternators that make the electricity which is sent from the power-station via the wires to houses, businesses etc that need the electricity.
Why is oil burnt in power stations?
Oil is burned in power stations to produce heat, which is used to generate steam. This steam then drives turbines connected to generators, producing electricity. Oil is used because it is a relatively cheap and reliable source of energy that can be easily transported and stored.
What needs wind to work?
Wind turbines need wind to work. The blades of a wind turbine are turned by the force of the wind. This turning motion then generates electricity through a generator connected to the blades.
What kind of fossil fuel do wind turbines need to produce electricity?
You obviously don't understand what fossil fuels are-coal, oil, natural gas. Wind turbines don't need any of these to produce electricity
Is dams built on rivers to produce electricity?
Because you need running water to spin the turbines to create electricity in a hydro plant.
How is hydroelectricity gathered?

Does wind energy use traditional fossil fuels?
No, wind energy does not rely on traditional fossil fuels to generate electricity. Wind turbines harness the power of the wind to produce renewable energy without the need for fossil fuels. This makes wind energy a clean and sustainable alternative to traditional sources of power.
Is hydro electricity sustainable?
Yes because hydro-electricity relies on turbines which need to be turned round. In most cases, it is made from dams(made on rivers), which relies on water passing through it to turn the turbines.
What are the disadvanteges of wind turbines?
The wind blows at a variety of speeds. The turbines need to produce electricity at a standard voltage. If the blades speed up and slow down as the wind changes speed the voltage will vary. They are hard to get right that way. They are placed in windy areas which is where birds fly. If they go too fast, they will kill a number of birds and thus be bad for the environment. The noise from the turbines can be unpleasant.
What we need to produce nuclear electricity?
steam turbine

Is it better to have a larger wind turbines?
It depends on how much electricity you need. But yes of course, a larger wind turbine traps more energy between its blades, so it is "better" in terms of how much electricity produced. However, if you think about it in terms of other things: 1. Sight pollution Larger wind turbines produce more sight pollution than small ones. 2. Animals Large wind turbines kill all birds or bats that fly into them but small ones don't.
