As the planet gets hotter, more people use air conditioners to keep cool. Running these takes lots of energy, which means emissions that then further speed up global warming. Rethinking our architecture and using more efficient cooling technologies could help us break this vicious circle.

@londonerabroad Interesting! We generate considerably more electricity from our rooftop solar than we need for our air conditioning. Once we have a ground source heat pump, we'll have even more excess energy to push into the grid.

What makes me optimistic is that we mostly need cooling during the sunny days when solar is plentiful and cooling is much more energy efficient than heating!

Good observation but I have noticed (here in Slovenia) that with climate change comes more frequent storms often with hailstones and these are doing a lot of damage to solar panels. Of course solar panel technology is also getting better and perhaps this too can be avoided. #solarpunk

@londonerabroad There’s some interesting points in the video, but they seem to mix up residential and commercial cooling a lot in the video, and they’re very different beasts. They also bring up points that (at least from a US/European perspective) aren’t really accurate anymore. For instance, R-410a (GWP: 2,088) is already being phased out for refrigerants like R-32 (GWP: 675). On top of that, district cooling is very common now but they ignore that it often uses cooling towers that use water.
