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 do not produce water pollutants, making this statement accurate for both energy sources.
The other statements are not universally true for both energy types. For instance, solar energy can only be collected during the day, and while both energy sources can be integrated into existing power grids, the ease of integration can vary based on location and infrastructure. Additionally, while energy collection equipment can often be installed in agricultural areas, it can potentially affect crop production depending on the type and placement of the equipment.
