In the US it makes sense. Much of our corn is grown for ethanol so ot can be used for fuel. Replace that with solar and we reduce our reliance on a monocrop and end up with far far more power.
They also use lots of irrigation from aquifers in the Great Plains, so they’ll need less irrigation and the shading will help a tiny bit with replenishing the aquifer.
In northern Europe these solar fields make no sense at all to me though. When I see something like the fields below in my temperate marine climate, then I can’t help but think of the forest that could have been there.
Turning it back into a forest will never happen when the land owner needs to pay taxes on the land and thus need to make income of the land. These solar fields are usual on private property. Not public land. Either they put windmills and solar on the fields or they raise cattle or grow crops. Which one is better for the environment overall?
If you destroy existing forest to make a farm, maybe. But if it’s an empty field and you want to do something with it, making it into a forest makes little sense. It’s complicated, very expensive, and doesn’t do much. Just let natural forests do their things, allow them to expand if you want more forests, don’t make one from scratch.
Making wild forests in a temperate climate is not complicated at all. Stamp a bunch of seeds into the ground, fence it off to keep grazers away, wait a few years, and boom there’s a new forest. Once it gets started, nature knows just fine how to grow forests, they’ve been around far longer than our meddling after all. The problem is humans, who need capital and incentives to let nature do it’s thing. Making the forest is cheap, buying the land is expensive. And a wild forest has little earning potential, so for private landholders it makes no financial sense.
But if there were incentives, then these solar panels could have been put above existing hardened surfaces (roads, parkings), and the unhardened land could have been returned to nature. We’d have both the solar panel fields and the forest. It requires a much larger up front investment, which is why it’s not going to happen without government incentives, and to get those, political will is needed, which is why it’s not going to happen anytime soon.
And we should absolutely be making more forests from scratch, Europe has a massive deforestation problem. Reforestation is already an official policy goal in the EU and in most (I assume) EU countries, and this could be one of the ways of achieving those goals.
