Sure, there might be some niche corner case where it actually pencils out better. But that's not really helpful when assessing the impact of this on a global scale. There's some other scenario that's the opposite that cancels the benefit out. And as far as heating is concerned, heat pumps are more efficient, and most electricity—when turned into resistive heat—is less efficient than burning the fuel directly. So the only case where it would be a benefit is if your heat is fuel-based, but your power is renewable, and this condition lasts most of the year.
