The latest rankings for the most energy-efficient states are out. And the winners are…
ACEEE (the American Council for an Energy-Efficiency Economy) has released its 2019 state energy efficiency scorecard—its 13th edition. ACEEE’s annual release is always welcome, as a chance to take stock of where we are—where state leadership is—in moving along one of our most powerful tools for energy sector progress.

“Twistocaloric” cooling technology, spelled out in Science, is based on an amazingly simple concept: the property of materials—think rubber bands, for example—to heat up when stretched, and cool down when released. These innovations (and similar recent work on elastocaloric cooling) are aimed straight at the heart of a major consumer of electricity: Cooling for refrigeration and air conditioning account for a fifth of global electricity demand in buildings, and are poised for lots of growth. Any successful efficiency improvements in that sector could be huge, and with twistocaloric cooling we’re talking about systems potentially 20% more efficient than our current (vapor-compression) technology.

If you’re getting a roommate, you might end up spending a lot of time together, so choosing a good one is something you probably want to give a lot of thought to.
The same is true for the energy that keeps your lights on. It’s why we just released a new video on the topic. The good news is that we’ve got a big range of clean options when it comes to choosing our electricity supply, as consumers and constituents, from the personal to the national. Options that can reduce waste, save money, and forestall the worst effects of climate change.
In other words, electricity choices we can all live with.
