You're correct that this ought to say "electricity" and not "power".
But I think you're wrong to think that gas is "critical" to any of the things you've listed. "Currently used" ... yes. "Not replaceable by electricity" ... no (unlike, e.g. air travel).
explain the cost to replace a hop drying kiln with an electrical one, including the grid load.
I'm not going to do that.
Electrical heat using heat pumps is cheaper than in-situ heating with any fossil fuel because (a) the base price per unit of energy is (or certainly can be) lower (b) the coefficient of performance is higher.
There are obviously costs to changing heating systems. But that doesn't mean that a gas heating system cannot be replaced by an electrical one.
to me, it sounds unreasonable. Let’s say this project was your responsibility, would this argument be enough for your supervisor to approve it?
I'm not aware of anyone saying "we must replace all uses of non-electrical heat pump-based heating with an electrical version".
My point, in response to the GGP (?) was the while e.g. gas heating may be in use now, it is not irreplaceable. This is quite different (right now, at least) for something like air transportation, where there is no feasible electrical solution.
There is no "project" under discussion.
