Cardiff is developing an energy-efficient heating system that could be a model for other cities.
According to this BBC report, the Welsh capital is planning a district heating network would capture energy created through waste incineration and distribute it via pipelines in the form of hot water or steam. Up to 20,000 nearby homes and businesses would be warmed.
The project has received £245,000 from the U.K. government. Proponents say the system would reduce both heating costs and energy-related emissions.
Sweden and Denmark are among the pioneers of district heating. In the U.S., the largest district heating system is in St. Paul, Minnesota, according to the city’s website. A similar network in Baltimore heats buildings in the downtown core. During warmer months, many district heating providers switch to chilled water to power air conditioners.
