Use this helpful tool from Energy.gov to calculate how much energy your aquaponics system will use:
If you’re trying to decide whether to invest in a more energy-efficient appliance or you’d like to determine your electricity loads, you may want to estimate appliance energy consumption.
FORMULA FOR ESTIMATING ENERGY CONSUMPTION
Use this formula to estimate an appliance’s energy use:
(Wattage × Hours Used Per Day) ÷ 1000 = Daily Kilowatt-hour (kWh) consumption
1 kilowatt (kW) = 1,000 Watts
Multiply this by the number of days you use the appliance during the year for the annual consumption in kWh per year.
