Some solar/wind farms might even be combined with hydroelectric stations.

I also wanted to ask about geothermal energy. Seems very popular with new construction. Why don’t we hear more about it though? Or am I running in the wrong circles?

Reeealy expensive on a large scale. Gotta drill pretty deep and create a circulation system, if you’re not near a hot area. I know a guy who did a poor-man’s geothermal by laying a couple hundred feet of sewer pipe 6 feet under his property and blowing air through it to provide his house with 58 degree air year round. That’s also not easy to do on a large scale though.
