A Totally Green Electric Grid Will Dramatically Speed Up Climate Action

Joe Biden’s emphasis on creating a 100% carbon-free system by 2035 could unlock major breakthroughs. But it’s a difficult path few other nations are taking.

The perfectly green electricity grid sought by Joe Biden isn’t the end of the fight against global warming. It’s the beginning.

Today, 40% of America’s electricity comes from carbon-free sources. The Democratic presidential candidate has made getting that to 100% by 2035 a centerpiece of his $2 trillion plan to address climate change and create jobs. Getting there would take an enormous expansion of solar and wind capacity in the U.S., backed by mass adoption of energy-storage technologies and hanging onto existing hydroelectric and nuclear plants.
