Plans to replace Bournemouth's current street lights with new Light-Emitting Diodes (LEDs) will be considered by councillors this week.
The lights will conserve energy better and reduce the towns carbon footprint.
Currently, the council spends £1.1 million a year on street light energy. If the new plans go ahead, it will lead to a 73% energy saving.
The new lights also emit a crisp, white light which is brighter compared to the older yellow street lights.
Councillor Michael Filer, Cabinet Member for Transport said, "As part of Bournemouth's commitment to being a green town it is vital we are always looking at ways to reduce our energy consumption and carbon foot-print.
"These new LEDs will not only make our streets brighter and safer, but will be helping the town move forward in its journey to becoming more sustainable."
