How to work out how much a device costs to use
Step 1: Check the label or manual to find out the wattage
1 Air Conditioning unit = 2600 watts or 2.6 kilowatts per hour(kWh)
Step 2: Check a recent energy bill to find out the cost per watt
Look for kWh (1KW typically costs 0,18¢ after tax)
Step 3: Apply this formula
COST = kWh x 0,18 (1KW typically costs 0,18¢ after tax)
Step 4: Know your costs
Air Conditioning unit = 2.6kWh x 0,18 = 0,47
Air Conditioning Costs 0,47¢ an hour!
