उत्तर
| Limitations of Solar energy | Limitations of Wind energy |
| Solar energy is difficult to employ. | Wind velocity necessary for wind-energy generation is not available everywhere |
| Solar energy cannot be used at night or on cloudy days. | The wind velocity at specific locations depends on many geographical factors |
| Solar energy is not available uniformly during the day time and at all the places on the earth. | Wind velocity is usually high on sea shores and therefore that environment is more appropriate for the installation of wind turbines |
