Wind power plants can't be setup everywhere. Certain conditions make some locations favourable for wind power projects, other sites unfit for any installations. We'll explore these below.
Wind power has boomed in recent years. For example, China DOUBLED their wind power capacity from 2009 to 2011  .
Nevertheless, there are several factors that limit the growth of wind power generation worldwide.
Physical issues affect the farm’s overall productivity and include the wind resources and terrain of the land among others.
The first question that must be asked is where is wind energy found?
When considering the wind power potential of a site, measurements of up to 12 months need to be analysed for the height of the turbines that are to be installed.
This is because wind patterns vary from season to season, so it's important to properly evaluate the expected annual returns from each site.
The terrain also affects wind power generation because the existence of complex hills and valleys or dense forests could complicate the flow of wind in a region. As such, some locations have strong winds but the flow is too complex or turbulent for exploiting wind energy.
Social issues affect the permission process for project approval and include public acceptance, noise levels and proximity to protected areas just to name a few.
The attitude of people towards wind power generation plants varies from place to place.
In countries like England, a lot of the developers have been forced to invest on offshore projects because people do not want to see wind turbines near their towns.
While it could make economic sense to site a wind farm near an urban centre, the social impact would prevent such proximity.
People often site visual impact as the main factor fuelling social resistance to wind farm development followed closely by the noise impact.
Activists who oppose wind farm developments have coined slogans like NIMBY – Not in My Back Yard ; , and BANANA – Build Absolutely Nothing Anywhere Near Anything  in their campaigns.
Finally, Economic factors come into play, these not only affect the locations of the wind farms but the sizes of the farms themselves.
The Economic issues include site accessibility, proximity to the grid and availability of installation equipment. It is best to locate your wind farm as close to an existing grid as possible.
It’s also vital that the grid can handle the capacity you plan to generate. If not, the wind farm developer or transmission company has to upgrade and extend the grid.
Remember that a wind farm can only be located in areas with good wind regimes, these are sometimes remote or isolated areas thus the grid improvements turn out to be expensive.
Another issue that affects the economics of generating wind power is site accessibility.
The size of a wind farm or the amount of power that can be generated is determined by the capacity that can be installed.
If the road access is limited, large blades cannot be transported to the site; also if the farm is offshore, the availability and cost of Turbine Installation Vessels (TIVs) will determine the size of your wind farm .
The upgrades of roads and grids as well as the acquisition of TIVs affects the investments costs of the wind farm thus developers often select sites that already have working infrastructure in place.
As with all energy solutions, wind electricity generation projects have a number of obstacles.
Nevertheless, the technology is deemed to be revolutionary and has been selected as the main power source for Europe’s 2020 goals to attain 20% renewables in their energy mix .
Despite opposition, 70% of UK on-shore wind farms still get permission to go online  . This is because of the great need and urgency for the development of clean renewable energy sources.
