Also, if you can. Some disadvantages countered... Example
Wind energy kills bird, yes but not many etc

Advantages
1. Wind energy is fueled by the wind, so it’s a clean fuel source. Wind energy doesn’t pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas. Wind turbines don’t produce atmospheric emissions that cause acid rain or greenhouse gasses.
2. Wind energy is a domestic source of energy, produced in the United States. The nation’s wind supply is abundant.
3. Wind energy relies on the renewable power of the wind, which can’t be used up. Wind is actually a form of solar energy; winds are caused by the heating of the atmosphere by the sun, the rotation of the earth, and the earth’s surface irregularities.
4. Wind energy is one of the lowest-priced renewable energy technologies available today, costing between 4 and 6 cents per kilowatt-hour, depending upon the wind resource and project financing of the particular project.
5. Wind turbines can be built on farms or ranches, thus benefiting the economy in rural areas, where most of the best wind sites are found. Farmers and ranchers can continue to work the land because the wind turbines use only a fraction of the land. Wind power plant owners make rent payments to the farmer or rancher for the use of the land.
Disadvantages
1. Wind power must compete with conventional generation sources on a cost basis. Depending on how energetic a wind site is, the wind farm may or may not be cost competitive. Even though the cost of wind power has decreased dramatically in the past 10 years, the technology requires a higher initial investment than fossil-fueled generators.
2. The major challenge to using wind as a source of power is that the wind is intermittent and it does not always blow when electricity is needed. Wind energy cannot be stored (unless batteries are used); and not all winds can be harnessed to meet the timing of electricity demands.
3. Good wind sites are often located in remote locations, far from cities where the electricity is needed. Transmission lines must be built to bring the electricity from the wind farm to the city.
4. Wind resource development may compete with other uses for the land and those alternative uses may be more highly valued than electricity generation.
5. Although wind power plants have relatively little impact on the environment compared to other conventional power plants, there is some concern over the noise produced by the rotor blades, aesthetic (visual) impacts, and sometimes birds have been killed by flying into the rotors. Most of these problems have been resolved or greatly reduced through technological development or by properly siting wind plants.
the wind generators are ridiculously expensive. And you need lots of them, and a huge expanse of land that has a near constant wind blowing.
the only reason wind farms are being built by energy companies is because our government provides massive tax credits and subsidies to the people who build them.
Well if you got wind constantly blowing around, why not take advantage of it?
Disadvantage? – Yes, don’t skydive over those field of blades.
