Profiteering Hampers U.S. Grid Expansion

Cars That Think

The United States is not building enough transmission lines to connect regional power networks. The deficit is driving up electricity prices, reducing grid reliability, and hobbling renewable energy deployment. About 40 corporations, valued at a trillion dollars, own the vast majority of transmission lines in the United States.
