Climate expert suggests Biden will have to 'admit there will be tradeoffs' to reach zero carbon goal

Climate activists and scientists have generally received former Vice President Joe Biden's plan to eliminate U.S. carbon emissions by 2035 warmly, but there will likely be some backlash ahead, especially regarding a potential reliance on wind and solar alternatives, The Guardian reports.

David Keith, a climate and energy expert at Harvard University who co-authored research in 2018 that found America's transition to solar and particularly wind would require up to 20 times more land area than previously thought, said windmills certainly shouldn't be abandoned moving forward, but suggested they could be limited. "You should tilt the energy system toward low land footprints, which means focusing on solar, nuclear, and carbon capture and storage, with wind at the margins," he told The Guardian.

Keith added that if the presumptive Democratic presidential nominee defeats President Trump, the incoming Biden administration will need to "admit there will be tradeoffs for a shared national goal" and that "there will be local decisions people don't like" en route to an emission-free future.
