Home Energy Audit & Reduction — FarmPal
Before adding renewable energy, reduce your energy needs by 50-70%. Efficiency is always cheaper than generation. A thorough energy audit reveals where your energy goes and how to slash consumption.
Principles
- The cheapest kilowatt-hour is the one you don't use
- Insulation and air sealing are the highest ROI energy investments
- LED lighting uses 75% less energy than incandescent
- Efficient refrigeration (modern fridge vs old) saves 500+ kWh/year
- Phantom loads (standby power) waste 5-10% of household electricity
- Propane for cooking and heating is more efficient than electric resistance
Action steps
Conduct a load audit
Use a Kill-A-Watt meter to measure every device. List watts × hours/day = Wh/day. Sum all loads. Typical US home: 30 kWh/day. Efficient homestead: 5-10 kWh/day.
Eliminate phantom loads
Use power strips with switches for electronics. Unplug chargers when not in use. Smart strips auto-cut standby power. This alone saves 5-10%.
Upgrade lighting and appliances
Replace all bulbs with LED. Upgrade to Energy Star fridge, chest freezer (more efficient than upright), and front-load washer. Consider propane for cooking and water heating.
Insulate and seal
Attic insulation to R-38+. Air seal around windows, doors, outlets, and penetrations. This reduces heating/cooling loads by 30-50%. Cheapest energy investment.
Size your renewable system to reduced needs
After efficiency upgrades, your solar/wind system will be 50-70% smaller and cheaper. Efficiency first, generation second.
Benefits
- Reduces energy bills 50-70% before any renewables
- Makes renewable systems smaller and cheaper
- Pays for itself in months, not years
- Increases comfort and home value
- Foundation for energy independence
