Joe Biden wants zero emissions by 2050, but time is ticking. So how will the country have to change over the next 30 years?

If America finally weans itself off planet-heating emissions, the country will look and feel very different.
Landscapes from coast to coast would be transformed, carpeted in wind turbines and solar panels, with enough new transmission lines to wrap around Earth 19 times. The populace would whiz past in their electric cars, to and from homes equipped with induction stoves and heat pumps. The air would be near-pristine. Hundreds of thousands of people who would have prematurely died from the toxic fossil-fuel age would still be alive.

It’s an appealing vision, according to Eric Larson, senior research engineer at Princeton University. “In general, it will be a more pleasant place to be living in when we get to net zero emissions,” he said. “We will have cleaner air, and [will] have done our part to avoid disastrous climate change. That’s a good thing for us and the rest of the world.”
Getting to this point by 2050 is a key goal set by Joe Biden in the effort to stem the worsening impacts of the climate crisis, which is already turning large parts of the US west to charcoal and pushing water to lap at the doorsteps of the nation’s coastal cities. But avoiding cataclysm requires a metamorphosis unlike any other in American history in a narrowing window of time.
“In terms of the pace of change, it’s unprecedented,” said Larson, who led a Princeton team’s exhaustive analysis of the path to net zero emissions that is helping guide the longer-term thinking of Biden’s administration. “It’s not going to be a walk in the park. We need to start now. And if we delay starting now, we’re going to have to go even faster.”
How quickly societies move away from coal, oil and gas is in many respects the defining, existential challenge of our time, one that the White House frames in both grim realism and fresh opportunity.
“Right now we are robbing young people of their future,” Gina McCarthy, the president’s top climate adviser, told the Guardian. “But there’s a bright future ahead if we work together. It’s doable and must-do at the same time.”
