Europe´s renewable ( green ) electricity production is about 15 percent of total ; is the US percentage considerably higher ?
The percentage of electricity from renewable sources varies a lot in different regions of the U.S. Some states have a Renewable Portfolio Standard (RPS) mandate that requires utilities to provide an increasing percentage of electricity from renewable sources.
My utility PG&E serves 15 million customers in central and northern California (including Tesla's factory and headquarters). Last year PG&E's power mix was 22% RPS eligible renewables plus 11% large hydroelectric power, totaling 33% renewables. (Large hydro doesn't count toward the RPS mandate).
These numbers do not count distributed (e.g. rooftop) solar PV as that production isn't metered as a grid source, though it reduces grid demand. PG&E's service area has 1/4 of all distributed solar PV systems in the U.S.
By 2020 RPS eligible renewables will have to be at least 33% of California's grid power. Adding in the large hydro will put California grid at ~44% renewables, plus whateever the distributed solar generation adds up to.
