Space heating and hot water account for around 70% of energy consumption in residential buildings. Any progress in buildings efficiencies will see overall energy consumption decline. But that presents a serious challenge to the existing business model: why invest in a sector that’s selling less energy? The answer is to change that business model, says Oskar Kvarnström, Energy Policy Analyst at the IEA. In doing so new doors are opened. At the consumer end you can stop selling kWhours and start selling heat as a service, selling as many things as an inspired entrepreneur can imagine. At the generation end you can integrate other industries (from data centres to pizza restaurants) so they can sell their excess heat into the network, and capture excess solar and wind generation through intelligent sector coupling. The author sees district heating as ideally suited to taking up the challenge.
