Solar energy's share of total US electricity generation was only about 3.9% as of 2023. So it's not powering all that much today. However, the cost of PV modules continue to come down and installed capacity is growing very quickly. Here's an excerpt from a recent post by Brian Potter about solar energy:

By some metrics, solar PV has been deployed faster than any other energy source in history, going from 100 terawatt-hours of generation to 1,000 terawatt-hours in just 8 years, compared to 12 years for wind and nuclear, 28 for natural gas, and 32 for coal. In the US, solar PV projects are by far the largest share of planned new electrical generation capacity.

And here's a chart:

It's also interesting to look at which US states have the highest "capacity factors." The average for the entire US is 23%, which means that, on average, solar panels produce 23% of what they would if the sun were shining 24 hours a day. You might also think that the "sunshine state" would be one of the highest. But in fact, the top states are Utah and Arizona:

I'm highly interested in solar and we want to deploy it as much as we can on our projects going forward. If you're also interested in solar and want to learn more, Brian's post is an excellent place to start.
