The London Underground could soon be entirely powered by renewable energy. Tweet This! The move is part of a plan to make the city’s famous rail network zero-emissions by 2030, and have the entire city become carbon neutral by 2050.
Transport for London (TfL) is London’s biggest electricity consumer, and one of the largest consumers in the UK. It uses 1.6TWh every year, the same as 437,000 average homes.
The Tube alone consumes 1.2TWh every year and that is without any of the buses, trams and overground trains that make up the network.
A recent study by British Business Energy calculated that 200 wind turbines or 5.6 million solar panels would be needed to power the network completely on renewables for one year. That many solar panels would take up the same amount of space as the London Borough of Kensington and Chelsea.
A city powered by renewable energy
Already, 16 per cent of the electricity used to power the operation of the Underground comes from renewable sources. Instead of filling central London with wind turbines to make up the rest, London City Hall has released the Underground’s energy requirements so that they can purchase the electricity from renewable energy suppliers.
“As one of the single biggest purchasers of energy in London, it is important that TfL leads the way on green energy,” said London Mayor Sadiq Khan. “This is a vital step towards my ambitions for TfL – and London – to be zero-carbon by 2030.”
City Hall is looking to expand the use of renewable energy in the future to its entire estate. That would cover all of the TfL network as well as the energy requirements of the police and fire services. The decision by the London Mayor was welcomed by environmental organisations, including Greenpeace and the Renewable Energy Association.
“This work to secure cost-effective and renewable energy for the rail network, with ambitions to include the wider [Greater London Authority] group and beyond, will play a key role in London’s green recovery and accelerating action on the climate emergency,” Khan added.
What about reducing electricity use altogether?
With nearly half of UK businesses working remotely due to COVID-19, commuting may never return to what it was before the crisis. People have got used to more flexible working hours and 45 per cent of people are expecting to have more flexibility in their work hours after lockdown ends.
If 45 per cent of London’s commuters continued to work remotely in the future, it would save over 460 thousand kWh of electricity, the same as powering 46,000 homes in the capital every day.
80% of the world’s 250 largest companies report in accordance with the GRI Standards
SustainCase was primarily created to demonstrate, through case studies, the importance of dealing with a company’s most important impacts in a structured way, with use of the GRI Standards. To show how today’s best-run companies are achieving economic, social and environmental success – and how you can too.
Research by well-recognised institutions is clearly proving that responsible companies can look to the future with optimism.
