City to convert street lights to save energy

The city of San Diego will use a $3 million state loan to purchase energy-efficient street lights, a lawmaker announced Thursday.

The loan from the State Energy Commission will allow the city to covert 5,700 sodium vapor street lights to induction lights, which last four times longer and use 50 percent less energy, according to Sen. Christine Kehoe, D-San Diego.

Once completed, the project will save the city an estimated $350,000 in energy and maintenance costs annually, according to her office.

The city must replay the loan with interest. Kehoe’s office said the city plans to pay off the loan in about eight years.
