Council officials in Leicestershire are looking into plans to switch off some street lighting overnight in a bid to cut costs and fight global warming.
Councillor Nick Rushton, deputy leader of the county council, said the idea would not be forced on residents.
He said anyone who wanted to suggest an area where lighting was not needed overnight should contact the council.
Rural villages have been suggested as possible locations to trial the authority's proposals.
Councillor Rushton said towns and busy roads would not be suitable areas.
"It's an idea worth pursuing because we're all very keen to cut down on electricity usage and carbon pollution.
"All the energy we buy is green energy but even so we'd like to use a little bit less of it," he said.
