What is a kWh?

• The k in kWh stands for kilo, which means 1,000.

• The W in kWh stands for Watt. A Watt is a measure of electrical energy. Household appliances, bulbs and equipment are labeled in Watts.

The h in kWh stands for hours.

kWh stands for 1,000 Watt-hours. A 100 Watt light bulb left on for 10 hours equals 1,000 Watt-hours, or 1 kWh.

What does a kWh cost?

On your electric bill, you pay about $0.10 for each kWh. Leaving a 100 Watt porch light on for 10 hours each

night will cost:

Using base-board space heaters (about 4,000 Watts) for 8 hours a day for 30 days will cost:

4 kW x 8 hrs x 30 days x $0.10

= $96.00 per month

x 10 hrs x 30 days x $0.10 = $3.00 per month 100 W1,000

Heating season savings

Small room heaters allow you to heat different rooms (zones) at different temperatures.

Zonal heating can be an effective way to reduce winter bills – heat only those rooms that are consistently occupied.

Keep doors closed and heaters off in un-used rooms.

Think zones:

Baseboard

Wall Heater

Portable Heater

7


Create a comfort zone: heat a small area of the home to a comfortable level using a zonal or portable electric heater.

Turn down zonal heating units in unused rooms to 55 degrees. Keep the zonal heater to 68 degrees in the comfort zone.

With a forced air furnace, turn down the furnace thermostat to 55 degrees and heat the comfort zone with a portable heater to 68 degrees

Use programmable feature or buy a programmable thermostat for forced air furnace

55 degrees

68deg

It all adds up…

Savings Reduce energy use and your bill

$8 per month

Setting back your thermostat from 72 to 68 degrees will save you 2 percent of your energy bill for each degree the thermostat is lowered.

$20 per month

Setting a comfort zone at 68 degrees and the rest of house at 55 degrees can save you approximately 20% on your energy bill.

Example savings are based off of a $100 per month energy bill.

Open drapes in the morning to let sunlight in to warm your house.

The sun can help heat your house in the winter:

Windows on the south side will let in more sunlight and warmth.

Close drapes at night to keep your house warm.

Cooling season savings

In the evening and morning when it’s cooler outside, keep your air conditioner off and open windows and curtains to naturally cool your home.

Use fans instead of an Air Conditioner.

Use a fan in place of a window air conditioner. A small window air conditioner can use 10 times the energy and cost 10 times as much as a fan.

Turn off your air conditioner when you’re away from home or set the temperature to 80 degrees or higher.

11

Water heating savings

Repair leaky water faucets

Don’t run hot water when shaving; fill the sink instead

Install low-flow showerheads

Take showers instead of baths: showers use half the hot water of a bath

Run your clothes washer with cold water and run only when full

Use your dishwasher (full loads) - it uses less energy than washing dishes by hand

Set water heater temperature to 120 degrees – turn off water heater at breaker panel first

12


Savings* Water heating measures

$3 per monthInstall a low flow shower head that uses 1.7 gallons per minute (gpm) or less (savings based on 1 shower per day and 2.5 gpm head replaced).

$3 per monthShorten your showers from 15 minutes to 10 minutes (savings based on 1 shower per day).

$3 per monthTake a 5 minute shower instead of 10 minute one (savings based on 1 shower per day).

$3 per monthTurn down your water heater from 140 degrees to 120 degrees.

*Your actual results may vary based on energy use and energy-efficiency measures.

13


Savings* Water Heating Measures

$4 per monthRunning the hot water 5 minutes instead of 10 minutes (5 minutes is saved using a basin or sink to wash the dishes in) (assumes 30 dish washings per month)

$5 per monthWashing clothes in warm water instead of hot water (30 washes per month)

$5 per monthWashing clothes in cold water instead of warm water (30 washes per month)

*Your actual results may vary based on energy use and energy-efficiency measures.

Saving energy with your refrigerator

Make sure your refrigerator door seals are air-tight. Test the seal by closing the door over a dollar bill. If you can pull the bill out very easily, you should replace the seal.

Allow leftovers to cool before placing in the refrigerator.

Keep your fridge stocked: a full refrigerator uses less energy than an empty one.

15

Saving energy with your refrigerator

Minimize the time the refrigerator door is open when getting and putting away food.

Allow at least one inch of space on each side of the refrigerator for good circulation. Poor circulation can increase energy use by up to 10 percent.

Set your fridge’s temperature between 37 and 40 degrees Consider getting rid of a second

refrigerator or freezer:

The Energy Trust of Oregon will pick up your extra fridge or

freezer and give you $50 cash.

Energy savings: washing/drying clothes

Only run your clothes washer and dryer when you have a full load.

Limit drying by hanging clothes to dry when possible. A clothes dryer costs around $0.50 per load:

5 kW x 1 hour x $0.10 = $0.50 per load Clean your dryer’s lint filter before every use.

Invest in a front loading washer: they use less energy and water and remove more water from clothes so less energy is needed to dry them.

17

Energy savings: lighting

Switch to Compact Fluorescent Light bulbs A CFL uses only 25% of the energy used by a regular

bulb and lasts up to 16 times longer.

A regular bulb run for 4 hrs per day will last 6 months; a CFL run for 4 hrs per day will last 8 years.

A 25 Watt CFL will save you $0.90 per month or $94.40 over the next 8 years.

Energy savings: cooking efficiently

Use small burners for small pots and big burners for big pots.

Use your microwave for everyday cooking tasks like boiling water, baking potatoes, and heating soup. It only uses 14% of the energy used by an oven.

Cover pots and pans with a lid

For health and safety:– Only use charcoal and other

grill cooking outside– Use exhaust fans while cooking

to remove moisture and odors

Thank you for saving energy

Remember, small changes to your daily and monthly habits will add up to BIG annual savings.
