Solar and wind power is growing worldwide, but so is electricity consumption: as a result, renewables are often only added to the energy mix, rather than replacing fossil fuels. 

Reducing energy demand would make net zero more achievable, but it recieves far less attention than decarbonisation efforts. This may be due to a perception that managing energy demand would be politically unpopular, requiring governments to make radical interventions into people’s lifestyles and spending. 

Oliver Broad, Senior Research Fellow at University College London, tells Alasdair that such fears are unfounded. His team’s research found that the UK could reduce energy demand by 52% without new tech or overly disruptive societal change, and has worked with policymakers and public focus groups to demonstrate political acceptability.
