A city is installing LED streetlights to reduce energy use. Each old light uses 150 watts; each new LED light uses 40 watts. If 800 lights are replaced, calculate the total power saved in kilowatts.
As cities across the U.S. aim to lower energy costs and meet climate goals, streetlight modernization is emerging as a practical, high-impact initiative. Replacing older, high-wattage fixtures with energy-efficient LED technology is no longer just a local upgrade—it’s a growing movement fueled by long-term savings and environmental responsibility. This shift is gaining visibility as communities pursue smarter infrastructure and reduced carbon footprints. With thousands of streetlights being replaced nationwide, understanding the scale of energy savings offers valuable insight into how public projects drive meaningful change.

Why A city is installing LED streetlights to reduce energy use. Each old light uses 150 watts; each new LED light uses 40 watts. If 800 lights are replaced, calculate the total power saved in kilowatts.
Today, energy efficiency in public infrastructure is a pressing priority for U.S. cities. With aging streetlight systems consuming significant power—especially in high-traffic urban and suburban areas—the transition to LED lighting represents a cost-effective, scalable solution. The move reflects broader trends in municipal spending: balancing operational savings with environmental stewardship. By replacing 800 outdated 150-watt lights with modern 40-watt LEDs, cities achieve marked reductions in electricity demand—an approach increasingly seen as essential to sustainable urban development.
Understanding the Context
How A city is installing LED streetlights to reduce energy use. Each old light uses 150 watts; each new LED light uses 40 watts. If 800 lights are replaced, calculate the total power saved in kilowatts.
The technical shift from 150-watt incandescent or high-pressure sodium lamps to 40-watt LEDs is simple but powerful. At 150 watts per old light and 40 watts per new LED, replacing one fixture saves 110 watts. Mult
