There is plenty of desert and piles of garbage which are great for building solar panels on. Another aspect often overlooked is shade is very important, there are methods where building solar panels can actually help the environment by providing much needed shade. You can also build solar panels of the water, theoretically you could build solar panels suspended in the air. And they don't really require much to hold them down, compared to a wind turbine which needs to basically be a tree. We just don't try. There is no effort to experiment because everyone is scared to change.
