Reflective solar is normal at least. But photovoltaics are weird. Even weirder is that they’re LEDs backwards, and the fact that transistors just are like that is why they’re encased in black plastic

Unless you WANT your transistor to be this way and use it so you put an actual led inside the plastic as well to mess with (i.e. turn on and off) the transistor!
Also I would argue that wind could also be considered ‘steam’ turning a turbine. It’s just vapour pressure ‘steam’ with a LOT of other pollutants which somehow increase the efficiency!
