Total Annual Lifecycle Energy Savings by Sector (mWh)
Lifecycle energy savings by sector measures the lifetime electricity saved from programs installed each year through 2024. These savings are effectively 'new supply' and help explain broad price and reliability trends.
Key Insights
Total lifecycle energy savings peaked in the late 2010s before declining sharply after 2020, reflecting reduced program impacts or shifts in efficiency investment. Commercial and residential sectors account for the majority of lifecycle savings, while industrial savings remain comparatively small and stable. Recent years show partial stabilization but not a full return to prior highs.
