What Drives Your Electric Bill
Biggest Savings Opportunities

Consumo por Electrodoméstico

HVAC: 3,500W (46% de la factura). Calentador de agua: 4,500W (14%). Secadora: 5,000W. Lavadora: 500W. Refrigerador: 150W continuo. TV grande: 100-200W. Computadora: 200-400W. LED: 10W (vs 60W incandescente). Para calcular costo: vatios × horas de uso ÷ 1,000 × tarifa por kWh. Un aire acondicionado (3,500W) × 8 horas × $0.15/kWh = $4.20/día.

Reduciendo Consumo

Los 5 mayores ahorros: termostato inteligente (-$100-200/año), LED en toda la casa (-$75-150), sellado de fugas de aire (-$50-200), electrodomésticos Energy Star al reemplazar, y eliminar cargas fantasma (electrónicos en standby consumen 5-10% del total). Una auditoría energética profesional ($100-300) identifica exactamente dónde pierde dinero tu casa.

⚡ CalcWolf Insight

The cheapest electricity is the electricity you do not use. Sealing air leaks (weatherstripping doors and caulking windows) costs $20-50 in materials and can reduce HVAC costs by 10-20%. This is the highest-ROI home improvement project possible — $20 investment saving $100-200/year.
