The Long View on Streetlight Retrofits

Publication Date: 

This working paper authored by CLTC Director Michael Siminovitch urges cities and municipalities preparing for streetlight retrofits to make sure adaptive controls are included in their near or long-term plans. Installing LED technology in place of high-pressure sodium sources can cut energy use roughly in half, but adding adaptive controls further reduces energy use by an additional 30–50%. Professor Siminovitch explains why and how project managers using public funds can maximize their climate impact and get better returns on their investments by selecting controls-compatible street lighting.
