Solar (photovoltaics), wind turbines, and hydroelectric are a few non-steam energy sources in use.
As for theoretical sources, some of the pulsed-power fusion concepts use the electromagnetic pulse from fusion to directly induce electrical power. But none of these have been demonstrated yet.
I would throw all turbines into one group, steam or otherwise. Your spinning a thing in a magnetic field to create electricity. PV is particularly cool because it doesn’t do that. It’s a totally separate technology.

There’s also natural gas turbines
