Future Energy Savings Driven by Commercial Applications

https://www.energy.gov/eere/ssl/ssl-forecast-report


The adoption of LED lighting is reaching the majority phase of product adoption, with most of the applications clustered in the “early majority” and “late majority” phases

Steady Growth in LED Lighting Adoption


Strong Energy Savings Potential

Low/High Bay, Parking Lot & Garage, and A-Type LED products currently save the most energy

Yet if paired with the overnight savings potential (95th percentile efficacy and 100% connected controls adoption), Linear Fixtures offer the highest savings potential

Progress in control technologies will be key to unlocking the full potential energy savings
