Chico, a city in California, U.S. will be replacing its streetlights with more efficient LED lights in the next four to six weeks, reported The Orion.

The Pacific Gas and Electric Company (PG&E) will supply the lights and head the project. The company will invest more than US $1.1 million in the next four years, which is expected to save $243,183 in power supply.

The streetlight project would help the city save more than $33,000 per year on maintenance and the cost of the light bulbs could ensure the bulbs can be maintained for the next 20 years, said Erik Gustafson, head of the Chico branch of PG&E.

PG&E will also provide related financial planning in this streetlight project, which will ensure the lamps installed in Chico and the costs and financial burden of changing the streetlights could be significantly reduced.

The LED streetlights are expected to save more than 500,000 kw/h per year for Chico, which is equivalent to 831,000 pounds of CO₂ emissions, said Gustafson.
