Crews have converted about 50% of its 58,000 street lights to LED lights.

The city has reached the halfway mark in its goal to reduce energy consumption in the nation's capital.

Crews have converted about 50% of its 58,000 street lights to LED lights.

The switch will allow the city to reduce energy consumption used for street lighting by 60%, saving taxpayers about $4-million.

"I am thrilled that the city is able to reduce its energy consumption and costs while still providing the best possible lighting infrastructure to residents. The millions that we save each and every year by using LED technology help us reinvest in other core services and keep taxes low," said Mayor Jim Watson.

The full conversion is expected to be finished by 2020.

New communities will have the LED bulbs added automatically.
