Good, and I use one. It's mind boggling that anyone wouldn't use one? It uses so little energy that I don't even notice. My stupid always-on smart TV uses more power...
Climate
Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:

How much each change to the atmosphere has warmed the world:

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
I wouldn't say I don't notice as it's most of my energy use. Monthly in summer we use 150-200kWh, in winter its 550-650. Heat pump does heating and hot water so the shower uses it too.
One thing that is hard about my unemployment was this was an upgrade we were hoping to make.
About fucking time. I've never understood why they weren't used to begin with.
In the northern locations they got a really bad name early on because the early models didn't do jack in colder climates, so it didn't make sense to have the pump and an additional heat source ontop of it so many just went to having a lone heat source like a furnace.
Since then they have steadily improved in tech and if you get the right type are good for locations that don't go under -23C (-10 F) but, they still have a bad name due to the experiences with the early tech.
they used to be expensive.
And so installers were harder to come by, which means fewer people were told about it. Pretty easy to understand why it took a while to catch on.
That's incredibly short-sighted since they still paid for themselves.
Cool beans. Try being poor.
Or inline water heaters. Seriously the whole world uses them.
They've been the standard around here for my entire lifetime. I'm in my first house that doesn't have one and when the air conditioner goes I'm replacing it with a heat pump.
Technology Connections is probably rejoicing at this news.

They are so much quieter and work a million times better than conventional ones.
Because each apart is now heated/cooled independently, so the tenant can pay utility costs. And heating/cooling are one unit and the price of heat pumps has really come down and are easy to install.
