About 60% of current electricity generation in the United States is from fossil fuels. The United States power grid was built to run on these fossil fuels. With the electrification of everything, the United States power grid will need to adapt and be upgraded to handle the advancements in electrical generation and distribution.
The United States power grid will need new transmission and distribution lines to connect renewable energy sources to population centers. The increasing electrification demands are already placing strains on the existing United States power grid, and the upgrades necessary to keep up will face many challenges.
