Home usage
Annual gas use by appliance. Look at your PG&E bill's Gas usage this year breakdown, or divide your annual total across these four buckets.
Typical: 300
Typical: 200
Typical: 25
Typical: 20
Appliance efficiencies
How much of each fuel actually turns into heat, hot water, cooking, or drying. Higher is better.
AFUE — % of gas turned into home heat (typical 78–96%)
Heat units delivered per electric unit (typical 2.5–4.0)
EF — same idea for water heating (typical 55–85%)
Water-heater version of COP (typical 3.0–4.0)
End-use efficiency (typical 35–45%)
End-use efficiency (typical 85–92%)
End-use efficiency (typical 55–65%)
vs a resistance dryer (typical 2.5–3.5)
