Which statement best describes wind power?

• A. Pros- Clean, renewable, least expensive Cons- Wind isn't always blowing, limited locations, expensive to install
• B. Pros- It uses water; Cons- No environmental impact
• C. Pros- Always reliable; Cons- Hard to install
• D. Pros- It requires fossil fuels; Cons- It has no environmental impact

Answer: (D)

Wind power provides clean, renewable energy by capturing the energy of moving air with turbines. A key idea is that wind output is variable because wind doesn’t always blow at a useful rate, so electricity generation fluctuates. Location matters too, since suitable wind resources and space for turbines are not available everywhere, which limits where wind farms can be built. Upfront installation and grid-connection costs can be high, even though operating costs after setup are relatively low. Among the statements, the one that describes wind power as clean and renewable while also noting intermittency, geographic constraints, and higher installation costs best captures how wind power truly works. The other descriptions include inaccuracies about wind power using water, having no environmental impact, being always reliable, or requiring fossil fuels.
