Energy Efficiency of Motors and Appliances

Energy Efficiency Purpose
The purpose of energy efficient appliances and motors is to be able to supply the same level of energy service only using less energy.
Efficient energy use is achieved primarily by means of a more efficient technology or process rather than by changes in individual behavior.
Energy conservation reduces the energy consumption and energy demand per capita and thus offsets some of the growth in energy supply needed to keep up with population growth.
Making a Difference
Along with saving money, energy efficient appliances and motors save the plant
The energy used to run a product can be cut up to 80%
There is a large potential to make a difference because all appliances energy usage can be cut
Fridges, washers, dryers, cars
Light bulbs, anything that plugs
Into an outlet.
Operation
You can apply new ways to your old appliances to make them more energy efficient
Keep air filters clean, vents clean, and baseboards clean
Get a furnace tune up
Defrost your refrigerator so ice doesn’t build up on the coils
Turn off appliance when they are not being used
Un-plug appliances
Motor Efficiency: Converting Electricity into Mechanical Motion
The energy efficiency of motors depends on the type of motor. Some are built to be more energy efficient while others are not. It may be wise to invest in motors with higher efficiencies than what is required, even if they are a bit more expensive. Energy efficient motors reduce the amount of lost energy going into heat rather than power by using steel with better magnetic qualities, bigger diameter wire, and better bearings. Since less heat is generated, less energy is needed to cool the motor with a fan—further improving energy efficiency.
