A billion people now live in a city with a renewable energy target or policy, almost a quarter of the global urban population. According to a new report from REN21, entitled Renewables in Cities Global Status Report, 799 cities have renewable energy policies while 834 had targets in place by the end of 2020. Of these, 796 cities had net zero commitments and 1,852 city governments had declared a climate emergency. This is particularly important for global decarbonisation efforts, as cities are responsible for around ¾ of global final energy use and account for around 75% of CO2 emissions from global final energy use. number of UK cities were highlighted in the report, with Oxford in particular highlighted for its commitment to decarbonisation. In 2019, the city declared a climate emergency and set a net zero target of 2030, while the City Council itself was targeting net zero in its own operations by the end of 2020. Part of this transformation includes the Energy Superhub Oxford, which is looking to reduce emissions by 40% through decarbonised heat and transport utilising heat pumps and EVs. Additionally, it is set to include the world’s largest hybrid energy storage system, with a 50MW battery supporting a 10km network of EV charging points and ground-source heat pumps in 200 homes. Other cities around the UK have set their sights on net zero, such as Manchester which is targeting 2038, Bristol which is targeting 2030 and Glasgow which is also targeting 2030. All these are aiming to reach the goal before the UK’s legally binding net zero by 2050 target. Within cities, many boroughs and areas have also set themselves key decarbonisation goals, such as of Hackney Council in London – which in 2020 announced it is now sourcing all of its electricity from 100% renewable sources.
