Since installing LED bulbs into street lights; Los Angeles has saved millions of dollars in energy bills every year. The widespread operation has just celebrated its fourth anniversary and continues to save to governing bodies of LA incredible amounts of money. Los Angeles Mayor Antonio Villaraigosa and ex-president Bill Clinton announced a partnership by the latter’s Clinton Climate Initiative to fit 140,000 street lights in LA with LED bulbs. Now UK councils are planning to do the same and hope to replicate the monetary success enjoyed by Los Angeles.
