Cardiff is expected to see the highest increase in domestic energy demand among UK cities by 2035.
That’s according to a report by Smart Energy GB which stated the average domestic electricity demand will grow by 44% and gas by 28% during the same period.
The growing demand will be driven by urban population and economic growth and a surge in the use of new technologies, including electric vehicles.
London and Bristol are expected to see the second and third highest increase, the report added.
Electricity and gas demand will rise by 39% and 23% in London and 34% and 19% in Bristol respectively.
UK cities that won’t see huge increases in energy demand are Liverpool, Newcastle and Sheffield.
The report also highlights smart meters will be installed in every home in Great Britain by 2020.
Sacha Deshmukh, Chief Executive of Smart Energy GB said: “This report looks at the challenges and opportunities ahead for our cities as energy demands change. It provides, for the first time, a detailed, city-level picture of future energy needs.
“Smart meters are an essential step to a smarter future. Many cities have already started to use smart technology to create cleaner, greener environments. With smart meters installed across the country there are great opportunities for further innovation.”
