Waste heat from data centres and sewage works may keep many people warm in a future low-carbon Britain.
Heat from industries and incineration could also be captured and piped to homes, hospitals, schools, and offices.
Warmth may also be sucked out rivers and the sea - and from old coalmines - using heat pumps which work like fridges in reverse.
A fifth of heat needed for buildings could come from so-called district heat networks, government advisers said.
These are grids of pipes laid under city streets to convey warm water generated at a centralised location by low-carbon technology.
