Methodology & Energy Data Sources for Boston
How we calculate whole-house dehumidifier energy costs in Boston, MA: 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 Boston reflects Massachusetts averages from EIA Form 861 (utility sales data). Rates vary by season (typically 10-20% summer premium) and time-of-use in many Massachusetts 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 Massachusetts.
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
- ENERGY STAR Product Finder — efficiency ratings for whole-house dehumidifiers
- DOE Energy Saver — Electricity — official tips and appliance comparison
- EPA eGRID — Regional Emissions — carbon intensity by grid region
- EIA State Energy Profiles — Massachusetts — generation mix, prices, and consumption
Disclaimer: Energy costs are estimates based on average appliance usage and Massachusetts 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.
