Whanganui District Council is considering installing solar panels on the Davis Library and the Whanganui Regional Museum.
The council's climate change advisor, Caroline Arrowsmith, said the sites were good candidates because both were open seven days a week, used power mostly during the day and had consistent annual power usage.
"There are also opportunities for education around solar power at these facilities," Arrowsmith said.
The Davis Library's roof is due to be replaced in 2024, and Arrowsmith said the current plan was to install the panels during that work.
The council building is currently also undergoing an audit to analyse the emissions currently released by the council's facilities.
Arrowsmith said the audit would then help identify where the council could then reduce their carbon footprint as part of the council's climate change work.
"Solar power is one thing we are looking at to reduce emissions, with the added bonus of reducing the council's power costs over time," Arrowsmith said.
