Arguably these are even greener than photovoltaics, since they don’t require the same kinds of materials to make (mostly just steel) and last longer than photovoltaics are supposed to. They use a fair bit of water, but you probably aren’t building them in places where water is at a premium.
Solar is an exception I think
True, but there are also solar steam systems, using a parabolic mirror to focus the sun on a steam drum.

Solar, wind, and hydro don’t use steam. (Well, hydro can bypass the steam part. It depends)
Hydroelectric is just liquid steam, and wind is just cold, thin steam.
