How much would you save if you bought a more efficient air conditioner?
HOW MUCH ENERGY ARE YOU USING?
Use the equation below to calculate how much energy you are currently using— and how large your savings would be if you replaced your old air conditioner with a higher efficiency air conditioner
For example: A person running a room air conditioner in Orlando, Florida, has an average operating time of 1500 hours each year. If the air conditioner has a capacity of 15 kBtu/hour (15,000 Btu/hour) and an Energy Efficiency Ratio (EER) of 7 Btu/hour per Watt, then the equation would look like this ANNUAL ENERGY USE
ENERGY EFFICIENCY RATIO
CAPACITY x OPERATING TIME
At an average charge of $0.10 per kWh, the annual cost to run the air conditioner (for 1500 hours)
would be $322. If the same consumer upgraded to an air conditioner with an EER of 11, annual energy use would drop to 2045 kWh
Well said.
