Estimating appliance and home electronic energy use
Knowing your electricity usage is a must before installing a wind turbine.
Following steps below.
1. Find wattage of the product
2. Estimate of time used
3. Find the daily energy consumption by using this formula
(Wattage × Hours Used Per Day) ÷ 1000 = Daily Kilowatt-hour (kWh) consumption
4. Find the annual energy consumption by using this formula
Daily kWh consumption × number of days used per year = annual energy consumption
5. Find the annual cost to run the appliance by using this formula
Annual energy consumption × utility rate per kWh = annual cost to run appliance
