How did the wind mill helps the environment?

Question

we are working with a wind mill power station, but we don't know the advantages of this power system

Answer 1

a wind mill,means milling grain by using the wind ,

they were used extensively in Holland before technolegy arrived ,and helped the people by providing cheap power ,not so much helped the Environment .

today we use wind power to  generate electricity they are wind power stations ,but they are not mills (nothing to do with grinding wheatgrains any more)

the advantages of wind power generators are that they Help the Environment because it is an alternative means of generating electricity ,

We do NOT have to burn coal (and so do not have to mine coal) and there is no black smoke that pours contamination into the atmosphere, with the very tall chimneys ,

it is also less labor intensive and altogether a very clean way of obtaining free power from the wind

These wind power generators are extensively used in Denmark ,they are a bit of an eye sore on the horizon ,but the environmental advantages out weigh that

further more wind propellars are also used to pump water to the surface in isolated places in farms in  (this is also not electricity but works with a drive shaft and gears that operate a pump)Australia ,the Americas .Africa .and probably everywhere else

Answer 2

I'm happy for the energy they provide, but certainly I'm not the only one concerned for the birds?  Heaven forbid they get disoriented and try to fly through one!

Answer 3

Because it do not pollute enviorment and uses only wind for power

Answer 4

The power getting from the wind energy is free from pollution, if we go for coal or petroleum product even we can take nuclear energy, all are giving the power but at the same time pollutants like CO, CO2, SO2, H2S, FUMES, SOOT, aerosol, SULPHATE DUSTS, NOX and some of the nuclear waste (after the fission operation) it'll produce the by products it needs to treatment to protect environment even if are treated the secondary pollution (less harm to immediate) will be there, the complete treatment is very costlier , but in the case wind energy is non polluting, no need of any treatment, So it's a help to the environment? or not sure! helpful to the environment.

Answer 5

A windmill is an engine powered by the wind to produce energy, often contained in a large building as in traditional post mills, smock mills and tower mills. The energy windmills produce can be used in many ways, traditionally for grinding grain or spices, pumping water, sawing wood or hammering seeds. Modern wind power machines are used for generating electricity and are more commonly called wind turbines.

Answer 6

This is a non- conventional source of energy. All other sources  of the conventional form either contribute to environmental pollution or are depleting sources. where as this source of wind or even solar are the ever lasting sources with minimal expenditure involved.

Answer 7

Moving air is wind.Wind has energy.Wind energy is cost effective,abundant ecofriendly and a natural resource.Wind is caused by uneven heating of the earth's surface.Today,wind mills ar used to generate electricity.The blades of the wind mill or wind turbines 'catch' the wind changing its direction from horizontal to vertical so that the blades spin like a pinwheel.Electricity can be generated even if the wind speeds are the low as 15 kmph.Usually a large number of wind turbines are placed together in an area.These are called as wind farms.

Answer 8

It doesn't pollute, and doesn't use electricity to create electricity. It harnesses wind for power.

Answer 9

wind mills uses the power of the wind to generate electricity. it does not pollute and it is renewable - as long as there is wind, the wind mill will continue to turn and produce electricity.

Answer 10

Wind power is renewable and produces no greenhouse gases during operation, such as carbon dioxide and methane.

Airflows can be used to run wind turbines and some are capable of producing 5 MW of power. Turbines with rated output of 1.5-3 MW have become the most common for commercial use. The power output of a turbine is a function of the cube of the wind speed, so as wind speed increases, power output increases dramatically.[3] Areas where winds are stronger and more constant, such as offshore and high altitude sites, are preferred locations for wind farms.

Wind power is the fastest growing of the renewable energy technologies. Over the past decade, global installed maximum capacity increased from 2,500 MW in 1992 to just over 40,000 MW at the end of 2003, at an annual growth rate of near 30%.[3] Due to the intermittency of wind resources, most deployed turbines in the EU produce electricity an average of 25% of their rated maximum power, (a load factor of 25%).[4], but under favourable wind regimes some reach 35% or higher. The load factor is generally higher in winter. It would mean that a typical 5 MW turbine in the EU would have an average output of 1.7 MW.

Globally, the long-term technical potential of wind energy is believed to be five times current production global energy consumption or 40 times current electricity demand. This could require large amounts of land to be utilized for wind turbines, particularly in areas of higher wind resources. Offshore resources experience mean wind speeds of ~90% greater than that of land, so offshore resources could contribute substantially more energy.[5] This number could also increase with higher altitude ground-based or airborne wind turbines.[6]

Wind strengths near the Earth's surface vary and thus cannot guarantee continuous power unless combined with other energy sources or storage systems. Some estimates suggest that 1,000 MW of conventional wind generation capacity can be relied on for just 333 MW of continuous power. While this might change as technology evolves, advocates have suggested incorporating wind power with other power sources, or the use of energy storage techniques, with this in mind. It is best used in the context of a system that has significant reserve capacity such as hydro, or reserve load, such as a desalination plant, to mitigate the economic effects of resource variability.

Answer 11

Energy produced by wind mill is pollution free and so it is good for the environment and all living beings. Almost all power sources except solor and wind and hydro power pollute. The problem with hydro power is that we need to make dams for big projects and this creates environmental and ecological problems but with other two it is not so.

Even wind power generating units have their own problems like they do not work well with slow wind and they are harmful for birds but even than they are a better option.
