Roof tiles are being used to generate electricity in a new development in Leeds.
A row of shops in the city is being refurbished and converted into environmentally-friendly flats for individuals.
Leeds City Council is overseeing the construction, which will involve roof tiles being made capable of producing energy.
This will then be connected to the National Grid, a statement from the local authority revealed.
Councillor Peter Gruen, executive board member for neighbourhoods and housing at Leeds City Council, said: "These new apartments will complement the overall regeneration of the Morley Town Centre area and are designed to have a minimal impact on the environment.
"They will be aimed at customers who are under-occupying larger family-sized homes which will assist in increasing the number of family-sized homes available to customers in the Morley area."
Leeds City Council has partnered with the Homes and Communities Agency, Yorkshire Housing and Aire Valley Homes Leeds over the new development.
