MIT Study: Transmission Is Key to a Low-Cost, Decarbonized US Grid Source: By Jeff St.John, Green Tech Media • Posted: Sunday, January 10, 2021 Modeling shows a nationwide transmission network could tap existing solar, wind and battery tech to reach zero-carbon power. Study after study over the past decade has concluded that expanding the U.S. transmission grid will play a key role in decarbonizing the country’s electricity system. But a new Massachusetts Institute of Technology study indicates that a massive U.S.-wide transmission build-out could also slash the costs of reaching a zero-carbon grid with wind, solar and battery technologies that are cost-effective today.
