I see this post creates some discussion, so I'll try to respond to all the comments so far in one go. Plants can do with *some* shade indeed, but usually these solar fields don't produce *some* shade, they cover the entire field. Those plants will have nothing but shade.
The graph @[email protected] shows how covering rooftops work. Australia and the Netherlands have a lot of rooftops covered with solar panels. Especially the Netherlands really has to, because though there are lots of roofs with solar panels there, still most of its electricity is produced elsewhere and it causes network congestion, a problem most dense populated European places suffer from. Rooftop solar panels can help against this: have the electricity produced where it's used, which means less network usage. This is one of the major reasons why every roof should have solar panels (the other reason obviously being that it's clean energy). I'm not at all demonising farmers though. Almost none of the solar fields are owned by farmers, they are owned by electricity companies. Farmers usually cover their barns with solar panels, which is a good thing.
What @[email protected] points out is a good thing: plants getting some shade from solar panels. But again, that's not what I tried to point out with this meme.
@[email protected] points out a situation in Denmark that I'm not aware of but I assume if they're anti-climate, I doubt they're in favour of any solar panel at all. I very much am in favour of solar panels, and contrary to their POV, I know solar panels on rooftops are not expensive at all. I got mine around five years ago and already earnt them back.
