Over the last several decades scientists have considered the problem of nonrenewable natural resources, such as fossil fuels. Humans are using fossil fuels at a rapid rate and scientists believe that one day, we will run out of usable fossil fuels. To solve this problem, research has been conducted on alternative energy sources. One alternative energy source is wind energy. Although wind energy is a good solution to this problem, it is not the perfect solution. Which statement describes a drawback to wind energy?

• Wind energy is a clean source of energy.

• Good locations for turbines are limited.

• Wind energy is inexpensive to set up and use.

• Wind energy plants do not involve the use of hazardous chemicals.
