Standard Recommendations/Guidelines for Energy Efficiency

Wasted energy plays a major factor in efficiency in energy use. Homeowners contribute to much of the wasted energy by not understanding the basic rules for running home appliances and devices effectively. In the beginning, it will be useful to learn the approximate amounts of electricity utilized by common appliances including systems, devices, and appliances at home:

Heating and Air Conditioning: 40 to 45%

Water heating: 14%

Appliances: 13%

Lighting: 9 – 10%

Television and other media equipment 4 to 4 –

This info, in conjunction with rules for using tools at home could help homeowners to save on energy. Examples:

HVAC and Heating: Set thermostat at 78F for summer. to 68F during winter.

Water heater: set temperature at 120F or less.

Appliances: Fill refrigerators to capacity but don’t overfill them; use ovens in the shortest amount possible during the summer.

Lighting: Replace your incandescent light bulbs with LED bulbs. LED light bulbs are long-lasting (lasting more years than incandescent light bulbs) They consume significantly less energy, and also are more efficient in lighting.

This same advice applies to electronics, TVs, and various other media equipment. Make sure it’s off when it’s not in use. These tips will help you comprehend the intricacies of energy efficient practices in your house.
