This year's list dropped on Monday, and I'm happy to share that there's not one, not two, but three items in the climate technology space. So in this week's newsletter, let's take a look at a few of these award-winning technologies you should know about. (And in honor of awards season, I'll include them in the bonus - and completely unofficial – categories.)
Super powerful solar cells
Solar panels are among the most important and perhaps best-known tools for addressing climate change. But one next-generation solar technology could help solar power become even more efficient and cheaper: perovskite tandem solar cells.
Enhanced geothermal systems
Sucking heat out of the ground is one of the oldest tricks in the book – there is evidence that people were using hot springs for heat over 10,000 years ago. We've since caught up and are using geothermal energy to generate electricity. But harnessing the energy radiating from the planet's core requires a specific set of factors: heat near the surface, permeable rock, and underground fluid. This significantly narrows the potential locations for usable geothermal energy, so a growing number of projects are working to expand access using so-called enhanced geothermal systems.
Heat pumps
Last but not least, we have the venerable heat pump. These devices, which can cool and heat using electricity, are my favorite climate technology. Heat pumps are super efficient, sometimes seeming to defy the laws of physics. In fact, they don’t break any laws, physical or otherwise, as I outlined last year in a deep dive into how the technology works. While they’re not exactly new, heat pumps are certainly breaking new ground. The technology surpassed gas furnace sales in the U.S. for the first time last year, and sales have been soaring around the world. Globally, heat pumps have the potential to cut emissions by 500 million tons by 2030—the same as taking all the cars off the road in Europe today. (Casey Crownhart)
