Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, what percentage of Government owned buildings have (a) solar panels and (b) wind turbines; and how many (i) solar panels and (ii) wind turbines were installed on Government buildings in each of the last 10 years.

Data on the total number of solar panels and wind turbines across the government estate, and how they are distributed, is not held centrally. However, the government is committed to driving forward the renewable energy agenda, both on its own estate and beyond. As set out in the Net Zero Strategy, the government aims to reduce greenhouse gas emissions from public sector buildings by 75% by 2037. To support this, £2.5 billion is being invested through the Public Sector Decarbonisation Scheme over the financial years 2020/21 to 2024/25 to provide grants for public sector bodies in England to fund heat decarbonisation and energy efficiency measures, including renewable electricity generation.

The Office of Government Property has published the Net Zero Estate Playbook providing guidance to support government property organisations to decarbonise their estate. This includes recommendations of how to reduce operational energy use, such as through improving renewable energy generation where appropriate through multiple channels.
