Popular Science: The US power grid is already halfway to carbon neutrality, and it’s saving lives. We’re seeing fewer pollution-related deaths a year. Renewable energy’s rapid growth is accelerating a national shift to a carbon-free electric power system.
So far 17 states plus Washington, D.C. and Puerto Rico, have adopted laws or executive orders setting goals for reaching 100-percent clean electricity by 2050 or sooner. And 46 US utilities have pledged to go carbon-free. Now the Biden administration and some members of Congress are proposing to decarbonize the power sector by 2035.
We analyzed the “business as usual” projection in the 2005 Annual Energy Outlook published by the Energy Information Administration, the US government’s official agency for data collection and analysis. It projected that annual carbon dioxide emissions from the electric power sector would rise from 2,400 million to 3,000 million metric tons from 2005 to 2020.
