The statement that is true for both solar energy and wind energy is:
Power generation using this energy source does not contribute to water pollution.
Both solar and wind energy generation processes typically do not result in water pollution, unlike some traditional energy sources.
The other statements are not accurate for both energy types:
- Energy collection equipment like solar panels and wind turbines can affect agricultural land usage, especially in terms of space and land management, though they can sometimes coexist with farming practices.
- Power generation from solar energy is limited to daytime, while wind energy can be generated at any time, depending on wind conditions.
- Integration into existing power grid systems can vary based on location, technological advancements, and infrastructure, so it's not universally easy for both types.
Hence, the second statement is the most universally true.
