Efficiency of Utilities

• Heat pump is 3x as efficient as electric heat.
• Point of use is 27-50% more efficient than tank water heater [1]
• Electric is 2x as efficient as gas - this one says 74% vs 40% efficient.
• induction is 20-25% more efficient than electric cooking - with induction at 90% and electric at 65-70% - [2].
• Electric water heaters (tank) are about 95% efficient, while gas are about 63% efficient [3]
• Efficiency factor (EF) considers standby loss but not distribution loss. Gas is 60% and electric is 90%. Tankless gets gas EF up to 82% (standby efficiency), but that doesn't consider distribution loss. Electric is 100% efficient to begin with, so standby would be near perfect efficiency. If you are at the point of use - you are close to 100% efficiency.
