what obstacles might exist in trying to harness wind energy?

location wildlife threatnoise pollution / visual obstructions competitivity

Explanation:

Although there are many locations with strong wind energy potential, these locations are not always located in an area with built-up infrastructure that is capable of taking advantage of the full potential. There are studies being carried out on the impact of wind turbines on migratory patterns of birds and also on the impact that the turbines have on their sensory functionality. Turbines can be noisy and in some locations have generated complaints from citizens for being unsightly. While this issue has lessened over time, wind energy cannot always compete with other sources of renewable and non-renewable energy.
