What about HVAC? My laptop and monitor probably add up to 100W. That's maybe $2 of electric per month? My added HVAC bill from being at home is much more, and I'm not sure how to split the bill for it.
Using about 190W - i6700 desktop - Dell Optiplex Mini and HPE mini server (Gen 10)
Don't use HVAC during winter - only during summer but it sits on another circuit.
