Home Made Energy - Build A Wind Power Generator
Perhaps one of the cheapest sources of energy is wind power. You can build a wind power generator at home and start generating electricity for your own consumption. Not only is the electricity produced by a wind generator much cheaper; the whole process is pollution-free as well.

Wind power generators have been around for an extremely long time, and have many parts, two of which are the gearbox and large rotor blades. Other parts include the wind mills or turbine which captures wind energy by rotating a propeller that in turn, rotates a shaft and powers a generator; the power storage; the DC/AC converter; and the power stabilizer which delivers home-made power and stabilizes the power feed to be constant and regular.
As the name suggests, they harness wind power and convert the kinetic energy of wind into electrical energy, which is then supplied to our homes through the connecting wires. It is also inexhaustible like sunlight. Therefore, wind power can provide us with an extremely clean and renewable supply of electricity.
The kit is readily available in the market. However, some varieties are more costly than the others, and so you should be able to choose your kit well. Ensure that the kit that you buy will give you a good quality product at a minimum price. Remember not to exchange the cost for quality, but also do not spend too much on something that will not give you more than what you can get from something cheaper. For around two hundred dollars, you can start building your home-made wind power generator.
Wind energy is unlimited, meaning, the power generated out of a wind power generator will give a lifetime benefit for our energy needs. Using wind power will help us reduce our electric bills by up to seventy percent, while reducing our reliance on fossil fuels and saving the world we live in.

Is using wind energy a revolution or just society shaping energy technology?
Will wind energy dominate? Are the people in society pushing for wind energy or is the wind energy technology shaping our society?
Do the costs of wind energy technology make it prohibitive for common use? Why or why not?
do the costs of wind energy technology make it prohibitive for common use? why or why not?
Using the wind to produce electricity in large quantities is a fairly new concept. Using the wind for power has been around as long as boats first used a sail to move it through the water.
Going Green is right that it will not become dominant because it is unpredictable. The problem with some of the others becoming major sources of power is the same. I live in the northern latitudes, where we get a lot of cloudy weather. We could not depend on solar as our main source of energy. There are a lot of days the wind is not blowing at all, especially in the summer. There are some places trying geothermal, but they have to go down so far to find the necessary heat, that the cost is too high to be practical.
There are no quick and easy solutions to the problem of alternatives to fossil fuels, and there won’t be any time soon.
right now the focus is on the aerodynamics and making them more efficient, there is also quite a bit of study going into the placement or trying to find the windiest places on earth, the turbines also seem to be killing bats and birds so they’re trying to solve that problem.
Wind sources for transport needs seem very promising. See study:
“Top 7 alternative energies listed”
4 January 2009 by Catherine Brahic
The US could replace all its cars and trucks with electric cars powered by wind turbines taking up less than 3 square kilometres – in theory, at least. That’s the conclusion of a detailed study ranking 11 types of non-fossil fuels according to their total ecological footprint and their benefit to human health.
The study, carried out by Mark Jacobson of the atmosphere and energy programme at Stanford University, found wind power to be by far the most desirable source of energy. Biofuels from corn and plant waste came right at the bottom of the list, along with nuclear power and “clean” coal.
The energy sources that Jacobson found most promising were, in descending order:
• Wind
• Concentrated solar power (mirrors heating a tower of water)
• Geothermal energy
• Tidal energy
• Solar panels
• Wave energy
• Hydroelectric dams
To compare the fuels, Jacobson calculated the impacts each would have if it alone powered the entire US fleet of cars and trucks.
He considered not just the quantities of greenhouse gases that would be emitted, but also the impact the fuels would have on the ecosystem – taking up land and polluting water, for instance. Also considered were the fuel’s impact on pollution and therefore human health, the availability of necessary resources, and the energy form’s reliability.
“The energy alternatives that are good are not the ones that people have been talking about the most,” says Jacobson.
“Some options that have been proposed are just downright awful,” he says. “Ethanol-based biofuels will actually cause more harm to human health, wildlife, water supply, and land use than current fossil fuels.”
Biofuel concerns
Jacobson says it would take 30 times more space to grow enough corn to power the US fleet than would be needed to erect enough wind turbines, while bioethanol would produce more greenhouse gases than wind power.
Biofuels have received a considerable amount of political backing in recent years with the US and Europe setting targets to phase in their use and gradually replace oil.
Energy and wildlife experts have expressed concerns about biofuels and the EU last year appeared to reconsider its position.
Nuclear is another energy source whose merits have been debated by European and US leaders alike in the past 12 months. “It results in 25 times more carbon and air pollution than wind,” says Jacobson. Half of those emissions are caused by the time it takes to plan and build a nuclear power plant – time during which fossil fuels have to be burnt for energy.
“Clean” coal – the process of burning coal then capturing the emitted carbon dioxide and storing it underground – is another political favourite. Jacobson’s calculations show that building and using enough clean coal power plants would emit up to 110 times more carbon than building and using wind turbines only.
Focused efforts
“The philosophy that we should try a little bit of everything is wrong,” says Jacobson. “We need to focus on the technologies that provide the best benefit. We know which these are.”
Jacobson acknowledges that politicians are calling for a massive jobs programme to pull the economy out of recession, but says investment in renewable energy is one way to do that.
“Putting people to work building wind turbines, solar plants, geothermal plants, electric vehicles, and transmission lines would not only create jobs but also reduce costs due to healthcare, crop damage, and climate damage – as well as provide the world with a truly unlimited supply of clean power,” he says.
Jacobson presented his results to the chairman of the Senate energy and Natural Resources Committee in October last year. They are published in Energy and Environmental Science this month (DOI: 10.1039/b809990c).
It is suitable for use in very few places. The most important is a supply of consistently strong wind, but not strong enough to destroy the turbines. The next is a clear open space where the turbines have unimpeded access to the wind, and there’s minimal harm to wildlife and minimal human impact of the noise. The next is access to a distribution infrastructure so the power can be transported to where it can be productively used.
You don’t use the term “electricity”, but rather “energy”, so then, I assume that you are not restricting it to electric generation (for which it only works with government changing the economics). If you meant to imply electric power, then, it cannot because of its erratic production, the land it requires, the materials use (a wind farm uses many times as much wire as a conventional nuke, hydro or fossil fuel plant because it is spread over 100s if not 1000s of hectares – and this adds to the amount of ore that has to be mined, and processed, etc.). And then it runs less than 40% of the time, so someone else has to put in a fossil fuel facility that has to be running, at least on stand-by all the time in order to provide the constant power for the level, or there have to be a lot of batteries (that use a lot of resources and have relatively short lives) to store the electricity for when the wind is either calm or too high. Kind of sucky, since it is unreliable and complex!
OTOH, Wind power has been in common use for centuries. Holland, Denmark and Spain have used windmills for a long time to pump water. They have been in use in the plains and other areas of the US, Canada, and Australia for at least 150 years to bring water to the surface for livestock and other uses. They run enough and are cheap enough to do the work needed.
