The project - which will take four years to complete - begins in May and will cost £4 million but savings are predicted to be £338,000 in the first year alone.
Councillor Bev Knott, a cabinet member for neighbourhoods, described the scheme as "an excellent move", adding: "Very importantly, it is a big cut to Bristol's carbon footprint and saves us money at the same time."
She also noted that the strategy would help towards making the city a leader in green energy.
In February last year, Coventry put into action a plan to change over 80 per cent of its street lamps using £64 million of private money, in a bid to cut carbon emissions.
