A 90% clean grid by 2035 would be cost-effective, says a report from UC Berkeley and GridLab; a companion policy paper calls for a federal renewables mandate to get there.
Under a 90% clean grid, wholesale electricity would cost less than it does today. And although a 55% clean grid in 2035 would have even lower electricity prices, when environmental and health damages from fossil fuel use are counted, the 90% clean grid would cost less.
It’s the early 1990s, and Park Williams stands in the middle of Folsom Lake, at the base of the Sierra Nevada foothills in Northern California. He’s not walking on water; severe drought has exposed the lakebed.
“I remember being very impressed by the incredible variability of water in the West and how it’s very rare that we actually have just enough water,” said Williams, who went on to become a climate scientist at Columbia University. “It’s often the case there’s either too much or too little.”
Williams is the lead author on a report out this month in the journal Science detailing the extent of drought conditions in the American West.
