Choose Energy Efficient Appliances
When an appliance needs replacement, consider both its purchase price and expected electricity consumption.
Compare:
- Energy efficiency information
- Estimated annual energy use
- Expected operating costs
- Appliance capacity
- Features that affect electricity consumption
A more efficient appliance may cost more initially but can have lower operating costs over its useful life.
Improve Insulation and Air Sealing
Although insulation is not an electrical device, it can influence electricity consumption by reducing the amount of work required from heating and cooling equipment.
Important areas include:
- Attics
- Exterior walls
- Floors
- Windows
- Doors
Air sealing can also reduce unwanted heat transfer around gaps and openings.
For homeowners using electric heating or cooling, reducing heat loss and heat gain can help lower the electricity required to maintain indoor temperatures.
Use Windows More Efficiently
Windows influence both natural lighting and indoor temperature.
During appropriate weather conditions:
- Use daylight instead of artificial lighting
- Open curtains when sunlight is beneficial
- Close shades when direct sunlight creates unwanted heat
- Check for obvious air leakage around window frames
The best approach changes with the season and local climate.
Reduce Electricity Used in the Kitchen
Kitchen appliances can contribute to household electricity consumption.
Practical habits include:
- Use the smallest suitable appliance for the task
- Avoid unnecessarily long cooking times
- Keep refrigerator doors closed
