This is just fucking dumb. Just a few percent of desert land would have to be covered in solar panels. And it's by no means a given, that solar panels are bad for the environment they're deployed in. Especially on desert land, they can also have positive effects. And then they'd agrivoltaics, i.e. the combination of solar panels and agriculture. That's still in its infancy but holds a lot of promise. Of course no form of energy generation is without an ecological impact but solar and wind are by far the best options we have.
