Wind energy is free and with modern technology can be captured very efficiently. Many people find wind farms an interesting feature on the landscape. Wind turbines after being manufactured produce no greenhouse gases. A disadvantage is that wind is not consistent from zero to gale force. Others see the farm of turbines as an eye sore and that the country should be left untouched. Wind turbines can also be noisy.

Advantages of wind power: . Wind power is very low cost (after the initial production and installation) . Wind power is clean (no pollution or carbon dioxide after the ini…tial setup, apart from the comparatively minor emissions produced to manufacture, transport, erect and maintain them) . Wind is a renewable and sustainable resource. We can use as much as we can today and there will still be more tomorrow. . Wind power will become cheaper than fossil fuel in the next few years (when the price of carbon is added to coal and oil), and in many places already is. . Wind turbines are self sufficient, just place them and watch 'em spin! (low maintenance, few moving parts, easy to repair) . Many people view wind turbines as aesthetically beautiful additions to the landscape. . Wind prices won't inflate like today's gas prices. . The land beneath can still be used for farming or any other purpose it was used for prior to a wind turbine being erected. . (For the US) At the moment we get our fuel (fossil fuels, mainly oil) from other countries. What would happen if one day they decided to cut off our power? Wind energy reduces US dependence on unstable, oil-producing countries. The benefits of wind power are that it is clean, produces no emissions, and is a renewable energy source. The greatest benefit of wind power is that the energy (i.e. the "fuel") component of the delivered power is FREE. Wind energy is provided ultimately by the sun and the rotation of the earth. The sun's radiation creates pressure differences in the atmosphere, and the rotation of the earth creates Coriolis forces. Together, these produce winds. Because wind energy comes from the sun and the earth's rotation, it is "FREE" in another aspect: it is completely non-polluting. Wind power, delivered to where people need it, is not free of all cost however. This is because we must build expensive windmills to turn the wind energy into electricity, and transmission lines to get the power where we need it. Also, the environment in the immediate vicinity of windmills will suffer in various ways, and with the suffering is associated an additional cost. Arguably, however, the environmental costs are usually much greater for other modes of power production, such as coal fired thermal power stations. Wind power does not require the burning of fossil fuels (beyond initial manufacturing and installation) to create electricity.
The advantages to solar power are an inexhaustible supply of the sunlight. The disadvantages include the cost and efficiency of solar cells. Nuclear power produces tremend…ous energy with little amounts of fuel. The downsides are storing radioactive wastes and risk of proliferating fissile materials. Wind power can produce significant energy, but it can harm landscape aesthetics in addition to endangering land and marine life. Hydroelectric generation produces the most efficient energy and minimal mechanical losses. However, the construction of dams alters hydrology, flood patterns, and can destroy ecosystems.
It is renewable, so we will always have wind power.It has no harmful carbon dioxide pollution causing global warming, unlike fossil fuels (coal, oil and natural gas).It is fre…e, after installation, so it will gradually reduce the cost of electricity.
Wind is free, renewable energy that can be turned into electricity.Wind has no polluting carbon dioxide emissions, so it has no effect on global warming.
The disadvantage of using wind powered turbines is that they might kill birds in some places. If it is a matter of a single turbine, then the wind might not always blow in the… specific direction needed to power the turbine. Keep in mind that there are always days that are not windy, although a sufficient battery should solve that problem. Answer They are one of the most expensive methods of energy generation in terms of cost per kilowatt hour, and only affordable because of enormous government subsidies which, of course, are then passed on to consumers throught their energy bills. They only produce a fraction of their rated capacity. They are completely dependent on wind and, so, do not necessarily produce energy when it is most required.

As most if not all governments are run by big business, wind energy would be a disadvantage to the mining industry, and any industry which depends upon fossel fuels. Governmen…t would loose most of its income which is supplies by big business. Taxes would therefor go up to help fill the governments coffers. Like most inventions that would affect big business they would be bought out and the project shelved.
Advantage: It will go further from parent plant and avoid overcrowding . Disadvantages: It will reduce the chance of survival for the seed as if it floats to a place without …soil, it cannot germinate.
Disadvantages of wind power:The strength of the wind is not constant and it varies from zero to storm force. This means that wind turbines do not produce the same amount of el…ectricity all the time. Luckily, wind energy isn't produced in isolation. It's added to widely connected energy grids with 24 hour spot energy markets. It's added to grids that span thousands of kilometres and have many types of generation and demand. Up to about 20% of a grid's generation capacity, it requires very little backup. Some people see large wind turbines as unsightly structures and not pleasant or interesting to look at. They believe that wind turbines degrade the landscape.Wind turbines generate noise. A subset of people who live near wind turbines find this noise annoying. A subset of those people get stressed by it. Wind turbine noise does not make people sick.Birds are killed by wind turbines. Studies show that wind turbines do not threaten the vast majority of bird species populations. Killing birds, in other words, does not threaten birds generally. That said, wind turbines should not be sited on raptor migration routes, as the Altamont wind turbine farm was. The best evidence is that song birds migrate at 2000-4000 feet, far above wind turbines and sea birds avoid them according to radar and thermal studies of North Sea wind farms.Bats are also killed by wind turbines, due to barotraumic stress (the reduced air pressure behind a wind turbine blade is damaging to bat's lungs and heart). However, bats are not killed in significant numbers compared to their populations by wind turbines. Bats are, however, killed in significant numbers in North America by white nose syndrome (300,000 in one cave alone.) The biggest thing is that it's only available when it's blowing. And even when it's blowing you don't get that much energy from each wind turbine, so you need a lot of them. They take a lot of place and are quite expensive to put up. Birds tend to fly into them and get killed. Because of the space (and the noise), they are usually built some distance away from any city, so the electricity has to be transported through lines into where it's used. Eco-friendly sceptics think they interfere with T.V. and make alot of noise, and that they affect the landscape badly... but i think they look fine and there isn't any scientific evidence to back up their other claims, and scientific evidence shows that wind turbines make the same noise as the wind in a tree if there is no wind, there is no energy:P Well some of the disadvantages or cons are: once the wind rises too much no power at all is generated badly placed wind power facilities can cause trouble for wildlife hard to maintain vibrations are made and can be extremely noisy for those nearby Sorry that is all I got look up what are the disadvantages and adventages of wind power and you will find a bunch of stuff.Later. you cant get winds patterns so theres no energy and the thing that collects needs alot of energy and it is using half the energy it makes
1) the weather is unpredictable 2) spoil aesthetic look 3) cost of building wind farms is expensive

Winds are the primary factors for all climate change including rain.It regulate temperature.It can be productively used in making wind energy as in wind mills and wind power. … Extreme wind can make disasters on earth.Some of the winds like dust winds,dry winds are also dangerous to humans.
Windmills have been known to kill birds and bats. Depending on citing, windmills may obstruct views of mountains or other scenic wonders. Electricity generated by wind mil…ls is dependent upon a steady supply of wind. Sometimes the winds do not blow, and once in awhile they blow too hard. Tornadoes and hurricanes can damage wind turbines.
Though they are both sustainable sources of energy, both of these forms of energy production are extremely expensive to create. Because solar energy is a relatively new form o…f energy, the materials and production of the final product are both complicated and expensive to create. Wind energy, though not new, is still quite expensive to make and maintain. The reason is because the turbines you see driving along the road are massive structures and have many components to clean, replace, and maintain throughout said turbines' life. So, though at face value, these are cheap, easy forms of energy, they actually are rather expensive ways to harvest energy. But, they are sustainable, and as long as the wind still blows and the sun shines, these forms of energy will always be viable.
In Solar Power
What are the advantages and disadvantages of using these resources geothermal and Biomass and Hydro power and solar and wind?
the advantages of solar power system, over geothermal, biomass, and hydro, are a) availability- the sun which is one of the most important success factor in solar is always …abundantly available, than in theses other power system. b) clean and cheap-the externalities of all these mentioned power sources are not clean or cheap, their after effect costs much more than what is paid by the consumers c) environmental impact- only solar power system is environmental friendly in all the above mentioned sources of power, green gas, damage to agriculture land, ecological imbalances, from all of them can only be imagined. d)running and maintenance- cost of running and maintenance of solar power system is near zero, while all other for these power system, their running and maintenance cost increases as they get older. i wish you can get my exposition on power systems compared, it answers this question in detail, with dates, tables and graphs.
