President Joe Biden’s moves to fight climate change are aimed at transforming the economy in a way that experts say will eventually change how Americans live. Biden’s ultimate goal is no additional carbon pollution by 2050. Experts say getting there will mean changes in how people drive and where they get their power, but it can be done. They say that because wind and solar energy is getting cheaper, changes in America’s electricity supply should be quiet and not so painful. But the nation moving from gas guzzlers to all-electric cars will be more obvious.
