Which is a disadvantage of using solar or wind energy to produce electricity?

• They are controlled energy resources.

• These energy sources are nonrenewable.

• They are an expensive way to produce energy.

• Their ability to produce energy is inconsistent and variable.

Which is MOST accurate in regards to energy resources?

• Fossil fuels are limited, therefore it is important to conserve energy.

• Solar radiation is limited, therefore it is important to conserve energy.

• Wind, water, and solar power generate pollution, therefore it is important to conserve energy.
