The mayor has revealed which London schools will benefit from his £2.9m Greener Schools programme, which aims to install solar panels, heat pumps and other technology across the capital.
A total of 38 schools in 16 boroughs will receive funding through the pilot, with councils contributing an extra £9.6m to the project, according to the Local Democracy Reporting Service.
City Hall said it believed the scheme could save schools an average of almost £15,000 on their energy bills as a result of the measures, which also include insulation and LED lighting.
The funding will also enable sustainability projects to take place, such as water conservation initiatives, the Sir Sadiq Khan's team said.
Schools in Barking and Dagenham, Barnet, Camden, Enfield, Hackney, Haringey, Islington Kensington & Chelsea, Lambeth, Lewisham, Newham, Southwark, Tower Hamlets, Waltham Forest, Wandsworth and Westminster have been selected for the scheme.
Sir Sadiq said he hoped to eventually see the project adopted by the government as part of a scaled-up national scheme.
He argued if all of London's schools were to use similar energy-saving interventions, this could save over £50m annually from the education budget.
