Oh that’s a good question! So both are good, it depends on the local climate on which one is better. So in Ireland for example, we have more wind and less sun, and so we make a lot of use of wind turbines. In sunnier places, solar panels can be more effective if there isn’t so much wind.
Generally wind turbines are more efficient than solar panels, but they require a lot space. Solar panels can go on roofs and existing buildings. There is a trade off depending on where they are installed.
