Measured how? If you mean delivered energy / higher heating value of fuel, I’d believe it. But a good heat pump may have a COP greater than 3. And an increasing fraction of grid power comes from renewables.
(I’ve seen swimming pool heaters with heat pumps that quote a COP of 6 in mild weather. In appropriate climates, you can get a heat pump that pumps heat from your house to your pool, which can be extremely efficient.)
