Today, over 70% of the U.S. electricity grid is more than 25 years old, and that aging system is vulnerable to increasingly intense storms. Also, the electric infrastructure in the U.S. was built to bring energy from where fossil fuels are burned to where the energy will be used. But as humanity responds to global warming, renewable, zero-carbon sources of energy, especially wind and solar energy, are replacing fossil fuels. That requires a new transmission grid.

They reported their findings Wednesday.
