California could be 100% renewable energy by 2050, say researchers

A combination of renewable energy from wind, water, and sunlight could power California completely by 2050, say perky researchers from Stanford. In my view they’re a bit too perky as well as overly We Know What Is Best For You.

First off, all those pesky gas and diesel vehicles would need to be completely replaced by electric, they say. No word on how electric semis would be able to haul multi-ton loads up the steep Grapevine outside of Los Angeles. No electric truck to my knowledge has the needed torque and power to do this. Maybe they will one day. But they don’t now.

Then there’s this.

[Wind, water, and sunlight] sources selected “ranked the highest among several proposed energy options for addressing pollution, public health, global warming, and energy security.”

Um, shouldn’t cost be a criteria too? Also, grid technology neccessary to support 100% renewables doesn’t exist yet. Perhaps it will soon. However, making projections based on technology that doesn’t exist yet seems a bit specious.

They claim going to 100% renewables would pay for itself.

“The California air-pollution health plus global climate cost benefits from eliminating California emissions could equal the $1.1 trillion installation cost of 603 GW of new power needed for a 100% all-purpose WWS system within ~7 (4–14) years.”

“Global climate cost benefits”, whatever that might be, do not pay for the project or decrease costs eleswhere and should not be included in cost calculations.
