compare_sites
shallowio.github.rozetyp/emission-factors · Verify this server
Compare and rank 2-25 candidate US sites (ZIP codes) for a facility, data center or EV/flexible load on grid carbon and electricity cost in one call. Per site: eGRID CO2e kg/kWh (location-based), Green-e residual mix (market-based), carbon-free %, $/kWh for the sector (the state's latest full-year average, EIA-861 annual; the ZIP's own 2023 utility average is shown as a reference), and the cleanest daily window from the 7-day hourly profile of its balancing authority, in the ZIP's local time. lowest_cost and best_combined are null unless every site has a rate. With annual_kwh, also annual tCO2e and cost. Returns competition ranks by carbon, cost and combined, gap percentages, and best_* = null with *_tied lists when sites tie.
