Wind and solar production is growing around the country and indeed setting short-lived records that soon get beaten.
On Earth Day wind and solar power provided 9% of California's peak electricity needs, according to the California grid operator. California gets about 55% of its electricity supply from natural gas plants and just 2% from coal plants.
By comparison, wind alone has provided as much as 4% of Pennsylvania's electricity for a very short period.
Wind in Iowa provides now about 20% of its annual needs and 7% of Texas' yearly power demand.
Wind and solar power are becoming mainstream and continue to grow rapidly.
