I wonder if my system is good or bad. My server needs 0.1kWh.

Watt hours makes sense to me. A watt hour is just a watt draw that runs for an hour, it’s right in the name.

Maybe you’ve just whooooshed me or something, I’ve never looked into Joules or why they’re better/worse.

Joules (J) are the official unit of energy. 1W=1J/s. That means 1Wh=3600J or that 1J is kinda like “1 Watt second”. You’re right that Wh is easier since everything is rated in Watts and it would be insane to measure energy consumption by seconds. Imagine getting your electric bill and it says you’ve used 3,157,200,000J.

3,157,200,000J

Or just 3.1572GJ.

Which apparently is how this Canadian natural gas company bills its customers: https://www.fortisbc.com/about-us/facilities-operations-and-energy-information/how-gas-is-measured

I guess it wouldn’t make sense to measure energy used by gas-powered appliances in Wh since they’re not rated in Watts. Still, measuring volume and then converting to energy seems unnecessarily complicated.

Thanks for the explainer, that makes a lot of sense.
