  • I’m just stating the facts. But as a European I have to say I’m pretty surprised by the attitudes in this thread. Almost no one I know has AC and we do just fine, seems folks are awfully protective of their AC. Obviously there are worse offenders in other industries but the source I gave you shows that by 2050 AC could be over 20% of GHG emissions, from 7% today which is still nothing to sneeze at.

    Here are some more facts (though the source kinda sucks, Quora):

    Indirect Environmental Impact: Even if the electricity powering your air conditioner comes from renewable sources like solar or wind power, there are still environmental impacts associated with the production and installation of the air conditioning unit itself. Manufacturing the units, transporting them, and disposing of them at the end of their life cycle all have environmental consequences.

    Energy Efficiency: The energy efficiency of the air conditioning unit is crucial. Even if the electricity comes from renewable sources, using an inefficient air conditioner will still consume more energy than necessary, putting strain on the grid and potentially increasing demand for non-renewable energy sources during peak times.

    Heat Island Effect: Air conditioning can contribute to the urban heat island effect, where cities are significantly warmer than rural areas due to human activities. This can have various environmental impacts, such as increased energy consumption, air pollution, and health risks.

    Refrigerants: Air conditioners use refrigerants that can be potent greenhouse gases if leaked into the atmosphere. Some older refrigerants like hydrofluorocarbons (HFCs) have a high global warming potential. Using air conditioners with environmentally friendly refrigerants can help mitigate this impact.

    And here is some more information on what European countries are doing to reduce the use of them, even to the point of dictating how low you can set the temperature and banning it in shops that leave the door open.








  • Yes, but also don’t turn them on until the last car that was passing you is slightly in front of you, too many people that turn them on while you’re still a bit behind, potentially in their blind spot, which can make you think they didn’t see you and maybe even swerve as a reflex.


  • Obi@sopuli.xyztoMicroblog Memes@lemmy.worldI can't disagree.

    Mine works like yours, it’ll jottle me a bit but if I want the car to go there it goes there, I don’t need special efforts to make it happen. It also has the auto-brake thing in case you’re about to rear end someone and I’ve set it to high to see it working but even that I only managed to make it beep and flash but not actually brake yet, looks like it would only do it pretty late. I think most people complaining about this are having an “back in my days” moment tbh, but maybe there are indeed cars out there where the implementation is more invasive.
