An extra £3 million to fund low carbon heat technologies have been awarded to local authorities across England and Wales.
DECC revealed the 55 local authorities that will share the cash, which will support 74 projects aimed at providing more efficient heat to buildings and potentially lowering heating bills while cutting emissions.
Heat will be distributed to homes and businesses from a central location from sources such as rivers or mine water, biomass, energy from waste or recovered heat through a system of insulated pipes carrying hot water.
Energy and Climate Secretary Ed Davey said: “Using wasted heat to warm our buildings is a cost effective way to cut carbon and slash energy bills.
“This money will help transform the way communities heat their buildings, schools and homes – as well as show how people and councils can work together to boost jobs and investment in their local area.”
Estimates suggest around 15% of the UK heat demand could be met by heat networks by 2030 and more than 40% by 2050.
