"To start with, there is no single U.S. electric grid."

"The U.S. electric grid is often described as a vast, synchronized machine — a network of wires carrying electricity from power plants across the country into our homes.

But, in reality, there is no single U.S. grid. There are three — one in the West, one in the East and one in Texas — that only connect at a few points and share little power between them.

Those grids are further divided into a patchwork of operators with competing interests. That makes it hard to build the long-distance power lines needed to transport wind and solar nationwide.

America’s fragmented electric grid, which was largely built to accommodate coal and gas plants, is becoming a major obstacle to efforts to fight climate change."
