Its so easy that you can’t name me a single city of more than 10000 people that runs entirely off renewables.

Weakly defined. What does "run entirely off renewables" mean?

We know that in North America, for example, significant energy use comes from transportation and heating requirements, and that at this time, very little transportation is powered by renewables, and not a whole lot of heat either (though both are growing).

On the other hand, the entire current residential electrical demand of the city of Santa Fe (about 82k people) can be met with a single relatively small PV+BESS plant (and might just be if it manages to get built).

Norway and British Columbia are 99% renewable energy and they have many cities larger than that.
