From the report:
"Most electric transmission and distribution lines were constructed in the 1950s and 1960s with a 50-year life expectancy, and the more than 640,000 miles of high-voltage transmission lines in the lower 48 states’ power grids are at full capacity."
"in 2015, 40% of additional power generation came from natural gas and renewable systems."
