- Most of the U.S. electric grid was built in the 1960s and 1970s. 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.
- 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.
- 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.
