how does wind energy system work?

Wind is a reliable energy source and the studies of its use is taking off. Wind energy system converts the power of the wind into turning a turbine which generates electricity.\n\nWind energy is starting to be more economical based on the conversion factor. It is growing at a rate of 37%. The cost of wind power has dropped 5 times over a period of about 8yr's.\nTruly a very good source of energy which can replace fossil fuel.\n\nRead the following for all the facts and figures on Wind Power.

It is where you use the energy of tidal flows to turn a turbine or such to produce electricity.\nIf you think about a dam using the energy of the water to turn turbines, much the same method is used to harness the wave energy.  However, it is not as efficient, and it is much harder to harness.  \nThere are other methods currently on trial, the web link below will take you to a site with the three main areas.  \nThe second one takes you to an educational site.\nGood luck

"An assembly consisting of a magnet mounted on a frame, and a wire coil (armature) that can be rotated within the magnetic field. The function of the generator is to convert mechanical energy into electrical energy."\n\nBasically in a generator you can induce current by rotating a magnet inside a wire coil.  The opposite of this is a motor in which the electricity causes mechanical movement.

I have a small wind turbine which uses permanent magnets instead of a field coil.  The main benefit I can see is in keeping the electronics on the ground.  As the wind speed increases, the output voltage (and power) from the generator will increase as well.  I have a shunt regulator at the batteries to prevent overcharging.  Everything outside on the tower is very simple and less likely to break.  Other than mechanical breakdown, repairs to the system can usually be made on the ground level.\n\nOn a gasoline powered generator, sometimes permanent magnets are turned inside the AC output coils.  This eliminates the need for brushes and the voltage regulator board.  AC output coils have been designed to supply 120VAC at 3600RPM.  If the engine speed changes, the output voltage will change as well.  Output voltage will also change with load variations.\n\nI have more generator information online.\nhttp://members.rennlist.org/warren/genfaq.html\nhttp://members.rennlist.org/warren/generator.html

A winmill does not generate energy.\nthe country of windmills is Holland

I dont want to copy the entire article from the site---please do visit the link below for full information\n\n\nA wind turbine is a machine for converting the mechanical energy in wind into electrical energy. If the mechanical energy is used directly by machinery, such as a pump or grinding stones, the machine is usually called a windmill. If the mechanical energy is then converted to electricity, the machine is called a wind generator\n\n\n\n\nhttp://en.wikipedia.org/wiki/Wind_turbines\n.\nhttp://www.howstuffworks.com/search.php\nhttp://windpower.getfast.info/wind_power/?kw=small%20wind%20electricity%20systems,wind%20turbine

they are nonrenewable resources.\nonce they been used once (burned) they finished with and cannot create anymore energy.\nThe world has a limited suply of these nonrenewable energy sources left.\n\nrenewable sources woud include solar (sun) wind and water power as these will never run out

Yes wind is definitely a renewable energy source. Take a look at the link provided for more info on RES and other examples.

Electricity and magnetism are closely related.  When a current goes through a wire, it creates a magnetic field around the wire.  Similarly, if a magnetic field is moved past a wire, it can induce a current.\n\nA generator spins a magnet past a series of coiled wires, inducing currents in them.  Generators and alternators both work in this way.  The difference between the two is that in a generator, the current always goes in the same direction, while in an alternator, it switches directions due to the fact that the polarity of the magnet changes as it rotates.\n\nGenerators always produce Direct Current (DC current), while alternators always produce Alternating Current (AC current).\n\nThe difference in nuclear, steam, coal, oil and hydroelectric powerplants is simply in how the rotation of the generator is produced.  The generators work in exactly the same way in each case.\n\nSolar power is different.  In the case of solar power, the current can be generated in one of several different ways.  These are more complicated, however, and I don't know the specifics of how they work.  Sorry.

Yes, you can, or more usually they turn themselves off when the wind gets too strong.   The power generated from the wind goes up as the cube of the windspeed.   So a 40 knot wind doesn't generate twice as much power as a 20 knot wind but 2x2x2=8 times as much.   So a fairly strong wind is too much for a wind generator to handle, and to prevent damage it automatically feathers the blades.   That is, it turns them parallel to the wind, so they don't turn.

It is renewable since warmth from the sun generates new wind all the time.\n\nThis is the opposite of oil.  Oil takes so long to produce that we use it up much faster than it is created in the earth.  We can actually use up all the oil.

In Scotland, there is a big plan underway to set up a giant wind farm and generate hydrogen via electrolysis to sell commercially for use in hydrogen cars. \n\nhttp://www.timesonline.co.uk/article/0,,2090-1743952,00.html\n\nI read somewhere else that there is a big controversy surrounding the building of these wind turbines, by another environmental group since they will interfere with the golden eagle population.\n\nhttp://news.scotsman.com/topics.cfm?tid=270&id=1472282006\n\nIt’s kind of rare that you see two environmental groups going at it with one another, so this caught my attention.

Energy that enters the system from the surroundings.

because its the force wind exerts on the propeller that creates the energy, we arent using wind as fuel.

I'm not sure exactly what kind of specs you're looking for, but these two sites have some great illustrations of how wind turbines work: http://www.awea.org/faq/index.html#Wind%20Power%20Technology\nhttp://www.windpower.org/en/tour/wtrb/rotor.htm\n\nIf you're looking for something else, Wikipedia may be a great place to start.

Define power.\nElectricity is the flow of electrons through a substance.\nIn the United States, electricity can be generated through coal/fossil fuel burning plants, nuclear power plants, wind(mills), and solar energy collection.\n\nIn fossil fuel and nuclear plants, they use the furnace and nuclear reactor to heat up water in order to turn a turbine, which spins around an electromagnet to generate electricity. There is much loss of energy through this process because much of the energy used to heat the water is lost through convection.  In windmills, the wind directly turns the turbine, so there is not as much loss, plus, it is a renewable resource.
