Wind energy is considered the leading and most efficient renewable power source. It brings in 8% of generated energy of the United States. Although wind energy isn’t as quiet as solar energy, it has a solid efficiency rating and is environmentally friendly.

Generally, using wind to generate electricity poses fewer damaging effects on the environment than other energy sources. For instance, wind turbines don’t release greenhouse gas emissions that pollute water or air. They also don’t need water for cooling.

Wind energy comes out on top, considering the costs of fuel, production, and environmental impact. To follow wind energy, in order of their efficiency, are geothermal energy, hydroelectric power, nuclear power, and solar power.
