  • 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.
















  • What I don’t get is that this is useful regardless of bikes. If you’re opening your door on the street side, then a vehicle could also rip out your door/you. The “Dutch reach” prevents that just as much as it prevents killing a cyclist. I dunno I do live in the Netherlands so maybe my perception is warped, but I’d never just swing my door open street-side without checking, bikes or no bikes.
