Which statement describes wind power limitations?

• A. Wind isn't always blowing
• B. Limited locations
• C. Expensive to install
• D. All of the above

Answer: (D)

Wind power limitations come from how variable and location-dependent it is, plus the upfront costs involved. Turbines only generate when the wind is blowing at suitable speeds, so output can fluctuate a lot and may require backup power or storage to meet demand. Not all places have strong, steady winds or suitable land or environmental conditions, so the best sites for turbines are limited, which restricts where wind farms can be built. And the initial investment for turbines, foundations, grid connections, and ongoing maintenance can be quite high, creating a financial barrier even though operating costs after installation can be relatively low. Put together, these factors show why wind power faces multiple important constraints, making all of the above accurate.
