Paris Olympics' AC-free ambition melts away as organisers order 2,500 AC units

- baggy_trough 2y agoMost people don't want to be uncomfortable or poorer to advance environmental plans that are extremely tenuously (to be generous) connected to climate change.
- jve 2y agoThere is a solution: solar panels. When you need AC, usually the solar electricity generation are at high levels. A single AC doesn't need much. My 3kW AC takes 5-6kWh on a hot 30+C day to cool down some 70m2 On those days a 10kW installation produced 59kWh and my panels aren't even positioned ideally south - they are something like SW. So that means 3 out of 25 of my 405W panels fully fed the AC. A few kW solar installation ain't that expensive if one wants to be eco-friendly.
- throwaway4good 2y agoYes. Solar panels, and air cons for that matter, are as cheap as ever. We europeans can easily afford this. Insisting on no air con is a cultural phenomenon. We associate it to something unneccessary, unnatural, excessive, distasteful, and wasteful. Our attitude is changing though ...

- okeuro49 2y agoFrance generates around 70pc of its electricity from nuclear. Who cares about this?
- vel0city 2y agoIt is not just the energy usage but also the refrigerants used. Most common refrigerants used in AC systems are pretty bad GHG'es themselves, often 2,000x worse than CO2. Are many small portable AC units these days running 1234yf yet?
- datadrivenangel 2y agoCan't you get R744 (CO2) AC systems these days?
- vel0city 2y agoI've yet to see many small portable ac units running R744 at least in the US. It requires really high pressures to run well.
- kamilner 2y agoI'm pretty sure most portable ACs sold in Europe these days are R290 (propane) which has a GWP of about 1/14th of CO2, so for those that's no longer much of a concern.
- vel0city 2y agoR290 has a GWP of 3.3, so that's 3.3x worse than CO2 with a GOP of 1. Which makes sense, because when propane breaks down it usually breaks down to CO2. Thanks for sharing that portable AC's in Europe are R290, I don't think that's super common in the US. But I'm open to being shown wrong on that!
- SkyPuncher 2y agoThis is not true anymore. Most systems are switching to less dangerous refrigerants.
