Why is it a terrible unit? And what would you replace it with?
It's reasonably human-scale, which is better than Joules...
If you want to pick on a terrible unit, pick on BTU.
- s1artibartfast 4y ago>And what would you replace it with just plain old kW. kW * hr/ hr is just 1 kW. A kW is relatable. About the same as an electric kettle, microwave oven, or 100 lightbulbs.
- BoiledCabbage 4y agokW is a useful measure of power kWh is a useful measure of total energy consumed kWh/{time} is a useless and just confusing unit. So yes, I think we all agree kWh/s is a bad unit, but kWh (or gWh or similar) are all useful units.
- Ekaros 4y agoWatts are the right mental model. Your stuff use some amount of power while running. Be it 50W for old lightbulb, or 1kW for space heater. You run this stuff for some amount during the day. Add all these up over a day for a city and you get to some total of power. Multiply it by hours and get to energy spend. And then you can even multiply the watt hours to get costs.

- Syonyk 4y agoWhich one? Scientific calories, or nutrition calories?
