But Census Bureau data show electricity, often in the form of efficient heat pumps, is becoming more popular.

Fifteen years ago, just over a third of homes heated with electric power, that's climbed to 42%.

The share of homes heating with natural gas has slipped two points to 47%.

Gas is mostly methane, a powerful greenhouse gas.

Scientists say to avoid the most damaging consequences of a hotter climate, nearly half the known gas reserves will have to stay in the ground.

Around the country, a few state and local governments have passed bans on installing gas in new homes.

You know, probably the most significant is something called the endangerment finding. In 2009, the EPA determined that human-caused greenhouse gases in the atmosphere that are heating up the planet, those endanger public health and welfare. This decision was years in the making.

Litigation that led to it went all the way to the Supreme Court, and now it's the basis for many of the country's climate regulations. EPA Administrator Lee Zeldin put out a video statement that suggests he thinks it's not constitutional.

Zeldin said the agency will reconsider rules that limit climate pollution from power plants and from cars and trucks. Also regulations that limit soot and mercury in the air. Other rules that Zeldin claims are hurting the economy and costing trillions of dollars. But that leaves out the fact that pollution also costs the country, you know, and health costs and cleanup costs.

It's not clear whether EPA plans to get rid of these rules or weaken them. Those details should come later. And what are environmental groups saying about this? You know, this is even more dramatic than what they expected and certainly more aggressive than the policies Trump pursued during his first administration.
