Methodology & Energy Data Sources for Tallahassee
How we calculate tankless water heater (electric) energy costs in Tallahassee, FL: Cost estimates use the standard formula: Annual Cost = (Wattage ÷ 1000) × Hours per Day × Days per Year × Local kWh Rate. We model regional electricity rate variation using EIA monthly data, which captures rate differences between investor-owned utilities, municipal providers, and rural electric cooperatives.
- Appliance wattage sourced from ENERGY STAR product database, manufacturer spec sheets, and DOE residential appliance test data.
- Local kWh rate for Tallahassee reflects Florida averages from EIA Form 861 (utility sales data). Rates vary by season (typically 10-20% summer premium) and time-of-use in many Florida 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 Florida.
Authoritative US energy data sources:
- EIA Electric Power Monthly — official US electricity rate data by state
- EIA Residential Energy Consumption Survey (RECS) — household appliance usage patterns
