Large amounts of heat are released to the atmosphere instead of being captured to serve connected user sites. Coordinated public policies are needed to meet the key challenge of capturing and redistributing this “lost” energy in district heating systems.

They are not easy to join, and it takes technical modifications, capital expenditure, regulations and a political commitment to do so.

The use of district heating systems varies significantly worldwide. Although the world’s first district heating systems were introduced in the United States in 1877, the country only uses them to meet 4% of its needs (see box below). Russia is the world leader (55%), but its systems are small and dated. China is expanding its systems at a fast pace. The situation in Europe presents sharp contrasts.
