How does Denmark use waste heat from electricity production?

In Denmark, the heat generated as a byproduct of electricity production—which would otherwise be wasted—is captured and used to heat water. This heated water is then distributed through piping systems to provide heat for homes and factories. This practice, known as district heating, allows the country to improve the efficiency of its energy production.1

By utilizing this thermal-heat recovery process, Denmark has been able to reduce its reliance on imported fuels and improve the overall sustainability of its energy sector. Facilities such as the District Heating Plant of Faaborg exemplify the infrastructure used to manage these energy systems.12
