- Appliance wattage sourced from ENERGY STAR product database, manufacturer spec sheets, and DOE residential appliance test data.
- Local kWh rate for Springfield reflects Illinois averages from EIA Form 861 (utility sales data). Rates vary by season (typically 10-20% summer premium) and time-of-use in many Illinois utilities.
- Usage patterns derived from RECS (Residential Energy Consumption Survey), EIA's official survey of US household energy use.
- Carbon footprint calculated using EPA eGRID emissions factors specific to your regional grid mix in Illinois.
Authoritative US energy data sources:
- EIA Electric Power Monthly — official US electricity rate data by state

Disclaimer: Energy costs are estimates based on average appliance usage and Illinois state-level kWh rates. Your actual costs depend on your specific utility provider, rate plan (flat, time-of-use, demand), local fees, taxes, and renewable energy credits. Check your utility bill for exact rates. For energy efficiency upgrades, consult your local utility's rebate programs and federal tax credits via ENERGY STAR Federal Tax Credits.
