In 2004, the Republic of Ireland produced 2.9% (690 million kilowatthours out of 23260 million kilowatthours) of its electric energy from wind, geothermal, solar, wood, and waste combined.

Electricity is a form of energy.\n\nIt can be generated from other forms of energy, for example, chemical energy (burning fuel, or a battery), mechanical energy (a windmill), nuclear energy (atomic fission reaction like in a power plant).\n\nIn a battery electrical energy is converted from the  potential energy stored in chemicals which is released when they combine.\n\nIn a fuel cell, chemical energy is released in another type of chemical reaction.\n\nNuclear plants, windmills, hydroelectric dams or burning fuel in a generator turns a turbine or motor which moves a coil of wire through a magnetic field which produces energy.\n\nIn thermoelectric energy, heat is turned into electricity when two different metals are heated.

There are many ways to create electricity, all basically involve converting another form of energy (usually kinetic energy, eg. hydroelectric plants, or heat energy, eg. nuclear,coal, geothermal).\n\nWikipedia has explantions of these, see the site in the source. It basically says:\n\nRotating turbines attached to electrical generators produce most commercially available electricity. Turbines may be driven by using steam, water, wind or other fluids as an intermediate energy carrier. The most common usage is by steam in fossil fuel power plants or nuclear power plants, and by water in hydroelectric dams. Small mobile generators are often driven by diesel engines, especially on ships, remote building sites or for emergency standby.\n\nFuel cells produce electricity using a variety of chemicals and are seen by some people to be the most likely source of power in the long term, especially if hydrogen can be used as the feedstock. However, hydrogen is usually only an energy carrier, and must be formed by some other power source.\n\nThe world relies mainly on coal and natural gas for power. The high capital requirements of nuclear power and the fear of its dangers have prevented the ordering of new nuclear power plants in North America since the 1970s.\n\nSteam turbines can be powered using steam produced from geothermal sources, solar energy, or Nuclear reactors, which use the energy created by the fission of radioactive plutonium or uranium to generate heat. Nuclear power plants often use a primary and secondary steam circuit to add an additional layer of protection between the location of the nuclear fuel and the generator room.\n\nHydroelectric power plants use water flowing directly through the turbines to power the generators. Tidal harnesses use the force of the moon on bodies of water to spin a turbine. Wind turbines use wind to turn turbines that are hooked up to a generator. Pumped-storage hydroelectricity is used to level demands on the power grid.\n\nPower generation by thermonuclear fusion has been suggested as a possible way of generating electricity; currently a number of technical obstacles and environmental concerns stand in the way, but if realized fusion might provide a relatively clean and safe source of electrical power. The construction of a large experimental reactor (ITER) is expected to commence in 2005-2006.\n\n\nPlease also note that a few places around the world produce usuable electric power from sources like geothermal energy, see: http://en.wikipedia.org/wiki/Geothermal_power, and wind power, see: http://en.wikipedia.org/wiki/Wind_power

Almost all power plants use some heat source (coal, natural gas, nuclear pile, geothermal heat, concentrated sun rays) to generate steam. The steam turns turbines. The turbines turn generators.\nGenerators generate electricity which is where electromagnetism comes in. A simple model is this: when you move a magnet around a wire you see a current induced in the wire. Now a generator moves a whole bunch of coils of wire around magnets (or moves magnets inside lots of coils of wire) and thus uses electromagnetism to generate electricity.

Electricity is a property of matter that results from the presence or movement of electric charge. Together with magnetism, it constitutes the fundamental interaction known as electromagnetism. Electricity is responsible for many well-known physical phenomena such as lightning, electric fields and electric currents, and is put to use in industrial applications such as electronics and electric power.

Electricity may be generated directly from solar panels (using the photo-electric effect) or from providing rotational force to an electric generator (just  wires moving across a magnetic field). \n\nAny form of energy that creates movement can be used for the generator -\n1. Apply heat to water to make steam to turn a turbine to turn a generator). The heat could be provided by fossil fuels, nuclear power, geothermal sources (eg hot springs), solar radiation.\n2. Use wind or water power to turn the generator (windmills & hydroelectric dams) \n3. Tidal power again to rotate a generator.\n\nAll these forms of electrcity generation require major capital expenditure that perhaps would be difficult for Ghana to afford. However, the windmills & solar panels are probably the easiest to implement since they could be implemented by an incremental approach. The disadvantage is the inability to match supply to demand.

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.

There is not enough wind power being generated for everyone who might want to buy it. And I would be suspicious too. How do you really KNOW that all your electricity comes from wind? Just because the electric company says it does? And you believe them? Wind power is just put on the power grid with all the other electricity, so it is all mixed up. You are depending on accountants at your power company to correctly calculate, second by second, that all the power from wind entering the network equals or exceeds all the power being used by customers paying extra to get wind power. I am not sure I trust them to do that.

wind is the result of air pressure, air molecules travel from low to high pressure zones, resulting from air warmed by the sun. The strength of the wind i guess would be dictated by the difference in pressure between two zones, and any obstacles it may have to pass over/through in between...

Pros: 1.  When it powers turbines to create cheap clean energy\n           2.   When there is wind in the sails so boaters can enjoy a\n                  day out on the water.\n           3.   When you go to fly a kite and there is enough wind  to\n                  make it air born.\nCons. 1.  Strong winds can topple large trees causing damage.\n            2.   Winds can create battering waves and tidal surges \n                  that flood low lying areas.\n            3.   Winds can create white out conditions in snowstorms\n                  leading to accidents.

Wind turns the propellers, which is connected to a turbine engine that converts the wind energy to electrical energy. I believe it is stored by batteries sometimes, or more commonly it is tied into the power system that it is associated with. Typically seen on farms because of their proximity to traditional power sources. Wind mills make it convenient because in the plains, there is an abundant source of wind.

I am going to take a guess and say the moon.\n\nNo, I am kidding, it's the Sun\n\nSolar energy can be converted in to electricity and heat.

I have studied this issue in the past and found the wind powered turbines online through a simple Froogle search.  Here's the link to the Alternative Energy Store:\n\nhttp://shop.altenergystore.com/items.asp?Cc=WINDGEN&CatMoveby=0&Nbm=&Pbm=&FromNav=
