Tax credits for clean energy and home energy efficiency would still be phased out, albeit less quickly, under Senate Republicans' latest proposed changes to a massive tax bill. Electric vehicle incentives and other provisions intended to move the United States away from fossil fuels would be gutted rapidly.

U.S. Senate Republicans have unveiled their version of President Donald Trump's sweeping tax-cut and spending bill that is broadly similar to the legislation that narrowly passed the House of Representatives last month.

The Senate version of the GOP tax bill included some noticeable changes from the House, making it a bit less populist than the House version.
