Methodology & Energy Data Sources for Meridian
How we calculate evaporative cooler energy costs in Meridian, ID: Cost estimates use the standard formula: Annual Cost = (Wattage ÷ 1000) × Hours per Day × Days per Year × Local kWh Rate. The default rate is the EIA Electric Power Monthly (Table 5.6.A) residential average for Idaho; it does not capture differences between investor-owned utilities, municipal providers, and rural electric cooperatives inside the state.
- Appliance wattage is a typical planning value for this appliance type, not a measurement of a specific model. Check the nameplate or manual for your unit.
- Default kWh rate for Meridian is the Idaho residential average from EIA Electric Power Monthly for 2026-06. Actual rates can vary by utility, season, and time-of-use plan.
- Usage patterns (8 hours/day, 120 days/year) are JouleIO planning assumptions; use the sliders to match your household. EIA's RECS survey is linked below for broader household energy-use context.
- Carbon footprint uses the EPA Greenhouse Gas Equivalencies U.S. average factor for electricity used (3.94 × 10⁻⁴ metric tons CO2/kWh, eGRID2022); regional grid mixes differ.
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 evaporative coolers
- DOE Energy Saver, Electricity, official tips and appliance comparison
- EPA eGRID, Regional Emissions, carbon intensity by grid region
- EIA State Energy Profiles, Idaho, generation mix, prices, and consumption
Disclaimer: Energy costs are estimates based on average appliance usage and Idaho 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.
