Home Electrification

Electrifying a house is four decisions that interact: heating, cooking, transport and storage. Whether they add up depends less on the equipment than on the ratio between your electricity and gas prices — a number set by policy rather than engineering, and one that varies enormously between countries.

We cover heat pumps, home batteries, rooftop solar and home EV charging with the arithmetic attached, including the cases where the numbers do not work. A heat pump in a country with a punitive electricity-to-gas ratio is a worse investment than the brochure suggests, and saying so is part of the job.
