Wind turbines could be put on the roofs of schools, libraries and care homes across Gloucestershire.
Labour members are urging the county council to install the energy generators on public buildings starting with Shire Hall in Gloucester.
Half the cost of the turbines would be met by the government's Low Carbon Buildings programme, the group said.
Coleford councillor Peter Chamberlain, said the move would demonstrate their commitment to the environment.
"Gloucestershire County Council needs to take its role seriously, and start making a difference," he said.
"The Government aims to increase renewable energy five-fold to 20% by 2020 and decentralise energy production and to do this everybody needs to play their part."
