Operating efficiency supports progress toward applicable building-emissions limits.
Cambridge emissions reductions begin in 2026 for covered nonresidential properties of 100,000+ sq ft; smaller covered properties follow later. Residential coverage is principally reporting.

About these electricity figures
EIA Table 7 reports 2024 revenue per kWh for bundled commercial utility customers, excluding separate third-party supply. The U.S. reference covers all commercial customers and provides context rather than an exact like-for-like comparison. These historical averages differ from current tariffs and individual building bills.
