so you're making the rest of us hotter >:(

You can always plant more trees, paint all the buildings brighter colors, live underground, or move north?

Yikes.
Yeah by like 400W which is peanuts compared to what the sun is doing
Also: if a big box store with high ceilings is going to cool the entire building to 68F, I'm not going to fret over cooling my modestly-sized home.
A typical air conditioner consumes 1kW, and on top of that heats the outside by however much the inside is cooled.
Yeah but that heat is merely redistributed, it's not like it's adding to the total temperature
I don't get the downvotes when you're literally correct.
Air conditioning is literally just moving heat from one space to another even at scale the air conditioning from homes is not enough to make any meaningful difference.
Now if we want to get pedantic the stress that it puts on electrical grids that are not decarbonized and have to fire up natural gas and coal plants harder sure it is technically making everything else hotter
Dunno about your country but mine is far from 100% reneable
100% renewable, nuts. I'd actually be thrilled just to get back to 1990s levels of coal and oil-based power plants. Even that seems so far out of reach as to be a fantasy, though.
So if we ignore everything but the actual physical heat coming out of the radiator then yes, it's really not that much, but unfortunately these units do not exist in a vacuum, and instead contribute to 3% of global emissions.
I'm running my air con in reverse cycle so the outside bit gets cold. Just doing my part to help offset old mates selfishness 🫡
