I doubt his electricity is carbon free. I don’t think he has enough collectors. For Denver to get its electricity from panels they would have to cover the whole rest of the state of Colorado.
Gore and his tin mines are the biggest polluter in Tenn.
Not eggzackly.
That (whole) state of CO presently consumes about 50B kwy annually. With metro Denver, at roughly 50% of state population, presumably consuming about half that.
According to this site, solar panels sufficient to generate that much electricity would require somewhere around 125 square miles.

State of CO is >104,000k square miles.
If you have other numbers, feel free to run them.
There are of course lots and lots of other problems with solar power, particularly in a climate like CO.
