In October, we found 15 fossil fuel power plants that have been kept open to help meet rising energy demand. Those 15 plants emitted nearly 65 million metric tons of greenhouse gas emissions in 2023, more than the entire state of MA did in 2022. 🧵2/2 frontiergroup.org/articles/dat...
Data center energy use is giving old, dirty power plants a new lease on life
The closures of 34 fossil fuel generators at 15 power plants have been postponed, in part to fuel the U.S. data center boom.

How energy efficiency benefits Americans
The typical American home uses about a third less energy than in 1980. The benefits of that shift - in cleaner air and consumer savings - are overwhelming.

Energy efficiency measures yield cleaner air and public health benefits. And they save money: Americans would have spent about $800 billion more on their energy bills – or $2,500 per capita – in 2014, were it not for energy efficiency improvements.
