Energy Conservation

 

Five Ways the Consumer Can Reduce Electricity Consumption, Reduce Electricity Bills and Reduce Harmful Air Emissions from Power Plants

Replace a 1970s refrigerator with a new EnergyStar refrigerator. This can save over 2,000 kWh per year and over $290 in electricity costs every year. This will also reduce carbon dioxide emissions by over 2,000 pounds every year.

Increase Air Conditioner thermostat by 3 degrees. This can save over 900 kWh per year, over $100 annually and over 900 pounds of carbon dioxide each year. Depending on the size of your home, you can save 3% on your cooling costs for every degree you raise your thermostat in the summer. Raising the thermostat from 73 to 78 degrees can reduce cooling costs by 15%.

Replace the five most frequently used incandescent light bulbs with compact fluorescent bulbs. This will save over 500 kWh per year, $75 annually and over 500 pounds of CO2.

Make sure your air conditioner is the proper size for the area you are cooling. An air conditioner that is too large will use more electricity than needed, an air conditioner that is too small will have to work harder to cool a space. The Department of Energy recommends the following:

Area To Be Cooled (sq. ft.)

Capacity (BTU/HR)

100 to 150

5,000

150 to 250

6,000

250 to 300

7,000

300 to 350

8,000

350 to 400

9,000

400 to 450

10,000

450 to 550

12,000

500 to 700

14,000

700 to 1,000

18,000

Conserve Energy! Don’t keep lights on in empty rooms. Only run the washing machine, dryer, and dishwasher when you have full loads. Cool only the rooms you use and utilize fans when the temperature is moderate.

Total energy used over 3 years

438 kWh per household

2.964 billion kWh if all households

100 w (4 hrs/day)(365 days/year)
(3 years) = 438000 watt-hours or 438 kWh

438 kWh(6,766,000) = 2.964 billion kWh

100.74 kWh per household

682 million kWh if all households

23 w (4 hrs/day)(365 days/year)
(3 years) = 100740 watts-hours or 100.74 kWh

100.74 kWh(6,766,000) = 682 million kWh

337.26 kWh per household

2.282 billion kWh if all households

(equivalent to the power generated from an 86.8 MW power plant, 24 hours every day.)

Total CO2 emissions over 3 yrs (avg emission rate: 996.7 lbs/MWh or 0.9967 lbs/kWh)

436.56 lbs per household

1,476,882 tons if all households

438 kWh (.9967 lbs/kWh) = 436.56 lbs

436.56 lbs (6,766,000)/2000 = 1,476,882 tons

100.41 lbs per household

339,687 tons if all households

100.74 kWh (.9967 lbs/kWh) = 100.41 lbs
