This particular one is in San Francisco, and it generates more energy during the day than the power it wastes during the night. It can generate about 3.4 kilowatts worth of energy, or 2.5 on a cloudy day.
I hope we see more of these. Way to go, PG&E. Keep thinking of ways to get some more power going on.
