Which device uses the most electricity?

A refrigerator that runs 365 days a year

A dishwasher that runs for 40 minutes three times a week

An alarm clock that rings for an hour to wake you up every school day

Your uncle’s old home phone

2 of 20

Which device uses the most electricity?

The correct answer is :
A refrigerator that runs 365 days a year
Because a refrigerator runs continuously, it uses twice as much energy as a dishwasher. On average, a fridge uses $40 worth of electricity a year, compared to $13.50 for a dishwasher. We bet you wanted us to say that your alarm clock uses too much electricity so you would have a good reason to unplug it for good, eh? Sorry!

3 of 20

What type of game uses the least electricity?

The correct answer is :
A Monopoly-style board game (tabletop version)
Okay, that was an easy one! However, you should know that recent video game consoles use more and more electricity. It’s not a huge cost: about $4 a year for one hour of playing time a day. But, just between us, do you really play for just one hour? Not to mention that, even in standby mode, most video game consoles continue to draw power and connect to the Internet for updates.

DID YOU KNOW?

Remember to unplug your console when you’ve finished playing. You can also unplug all your accessories (cameras, sensors and other peripherals) when they’re not in use because they use energy too. These are referred to as “phantom loads.”

An indoor clothesline

A dryer

A blow dryer

An outdoor clothesline

4 of 20

In colder months, the most energy-efficient way to dry your clothes is to use

The correct answer is :
A dryer
As a rule, it takes 40 to 60 minutes to dry clothes properly. There’s no benefit to selecting the hottest temperature option: your clothes won’t dry any faster!

4 of 20

DID YOU KNOW?

For maximum efficiency, clean the lint filter regularly and use the automatic shut-off function. In the summer, using an outdoor clothesline is the way to go!

Take a daily bath in a standard 1.5-metre (5-foot) tub

Use the garden hose outside

Wash every three days

5 of 20

What’s the most affordable way to wash?

The correct answer is :
Take one shower a day
Using a WaterSense® labeled showerhead can reduce your water consumption by 40%. Sure, you could wash only once every three days, but you’ve got to think about the people around you! You don’t want to share your B.O. with them!

5 of 20

DID YOU KNOW?

You can purchase a WaterSense® showerhead at most hardware and home renovation stores.

What is the most economical way to boil water?

Use a kettle

Use a pot on the stove

Use a microwave

Use a bonfire

6 of 20

What is the most economical way to boil water?

The correct answer is :
Use a kettle
Boiling water every day for three minutes costs about $2.50 a year if you use an electric kettle. If you use a pot on the stove, it takes longer for the water to reach the boiling point and it can cost up to $70 a year. A microwave oven uses a little more energy than a kettle, but much less than the stove. It’s a good second choice.

6 of 20

DID YOU KNOW?

To avoid boiling water needlessly, make sure you don’t overfill the kettle.

What’s the best way to save energy when washing dishes?

Wash your dishes by hand

Use a dishwasher

Get your brother or sister to do the dishes

Wash your dishes in cold water

7 of 20

What’s the best way to save energy when washing dishes?

The correct answer is :
Use a dishwasher
Today’s dishwashers, especially ENERGY STAR® certified models, are so efficient that they use about half as much hot water as doing the dishes in the sink. Nice try for your brother or sister, but remember that even if you delegate this chore to someone else, they still have to use hot water!

7 of 20

DID YOU KNOW?

It’s best to start the dishwasher only when it’s completely full and to use the shortest cycle possible. Also, it’s more economical to let your dishes dry using the Air Dry (no heat) option, which uses about 15% to 50% less energy than the Heat Dry option.

7 of 20

What’s the most energy-efficient device for keeping your food cold?

A recent-model refrigerator in your kitchen that meets your day-to-day needs

An older appliance, used primarily as a backup fridge for juice, beer and soft drinks, installed in your garage or basement

A cooler

None of the above

8 of 20

What’s the most energy-efficient device for keeping your food cold?

The correct answer is :
A recent-model refrigerator in your kitchen that meets your day-to-day needs
Recent models are better designed and use 60% less energy than older models. And do you really need a second fridge?

8 of 20

DID YOU KNOW?

The refrigerator is a household’s most energy-hungry appliance because it runs day and night to keep your food cold. Think about what you want to eat or drink before you open the door: every time you open it, the cold air escapes. The longer you leave the door open, the warmer it gets inside.

9 of 20

You want to do something to keep Fido company when you’re gone. Which of the following options uses the least energy?

The correct answer is :
Leave a radio or MP3 player on
Unfortunately, you can’t bring your pet with you everywhere. A radio or MP3 player uses up to 20 times less energy than a TV. An ENERGY STAR® certified television draws from 25% to 40% less power than a non-certified model. However, it uses more power than the other devices mentioned.

What is the most economical way to do the laundry?

Wash and rinse your clothes in hot water

Wash and rinse your clothes in cold water

Wear the same clothes several times before you wash them

Let your parents do the laundry

10 of 20

What is the most economical way to do the laundry?

The correct answer is :
Wash and rinse your clothes in cold water
On average, doing a load of laundry in cold water costs about 1.5 ¢, while doing the same load in hot water costs nearly $0.50. Nice try getting your parents to do the laundry, but it wouldn’t save you any money! It’s also a good idea to wear your clothes more than once before washing them, but sooner or later, you’ll be forced to take the plunge!

10 of 20

DID YOU KNOW?

Be sure to fill the clothes washer as much as possible. It takes less energy to do one big load than two small loads. It makes sense, and it’s much faster too!

Using a reading light with an LED bulb

Using a flashlight

Reading by candlelight

11 of 20

You want to spend an evening reading a good book, and you need some light. What’s the most energy-efficient option?

The correct answer is :
Using a blow dryer for 15 minutes
A blow dryer uses 1,500 W of power, while a microwave uses 1,200 W. Over the same operating time, a blow dryer uses more energy. Reading by candlelight! Congratulations on being such a romantic, but it’s far too dangerous. You might start a fire!

11 of 20

DID YOU KNOW?

Using a reading light with an incandescent bulb for three hours a day, 365 days a year, might cost about $5 a year, compared to $0.60 for a reading light with an LED bulb.

A chest freezer

An upright freezer (with manual defrost)

An upright freezer (with automatic defrost)

A cooler

12 de 20

What is the most economical option for storing ice cream?

The correct answer is :
A chest freezer
It can cost up to $60 a year to run an upright freezer, compared to about $30 for a chest freezer. That’s why a chest freezer is the most efficient choice for your ice cream. And a cooler? Get real!

12 of 20

DID YOU KNOW?

For optimal efficiency and to ensure your food is safe, set your freezer at −18°C, regardless of the make and model. Setting your freezer just 5°C lower draws up to 25% more power! You might not think this is the most exciting question, but you have to admit that when we’re talking about ice cream, interest really heats up . . . oops, cools down! Care to join us for a bowl?

12 of 20

In winter, what’s the most economical way to keep warm?

Put on warmer clothes

Raise the thermostat by 5°C so the room heats up faster

Drink a hot chocolate

Take a 15-minute hot shower

13 of 20

In winter, what’s the most economical way to keep warm?

The correct answer is :
Put on warmer clothes
You might want to put on some warm pants, cozy socks and maybe a sweater! Setting the thermostat higher doesn’t heat the room up any faster and may only overheat it needlessly. Taking a hot shower is the most expensive option: after all, 15 minutes is pretty long! And while it’s not a long-term solution, a cup of hot chocolate is a great way to indulge your sweet tooth!

13 of 20

DID YOU KNOW?

Did you know that heating accounts for half of a family’s annual electricity costs? Lowering the temperature by just 1°C can save you 5% to 7% on your electricity bill. Another good strategy is to open the curtains and let the sun heat your home. Try these simple tips at home or talk about them with your parents!

13 of 20

What is the best method for drying your clothes?

Using the dryer for 40 to 60 minutes

Using the high-temperature dryer setting with no timer (programmed cycle)

Using the low-temperature dryer setting for 120 minutes

Using the dryer at room temperature

14 of 20

What is the best method for drying your clothes?

The correct answer is :
Using a dryer for 40 to 60 minutes
Excessive drying time uses more electricity and will cause your clothes to wrinkle and shrink. And running your dryer too long at a high temperature or even just at room temperature is not an environmentally friendly choice!

14 of 20

DID YOU KNOW?

Choose medium or low heat, even if you’re in a hurry. Raising the temperature will not dry your clothes any faster and will only waste energy. And be sure to clean out the lint filter after every cycle!

What is the most economical way to prepare a meal?

Use the stove

Use an electric slow cooker

Have it delivered by a restaurant

Eat at Grandma’s place

15 of 20

What is the most economical way to prepare a meal?

The correct answer is :
Use an electric slow cooker
A slow cooker uses up to 80% less energy than a stove. A restaurant meal might be a nice treat, but it’s certainly not the most economical solution! And whether you have your meal delivered or choose to eat at Grandma’s, cooking it still takes electricity!

15 of 20

DID YOU KNOW?

Considered a small appliance, a slow cooker cooks food very gently. Even though it takes longer than a stove, it’s an economic and equally delicious solution!

15 of 20

What’s the most affordable way to cool your home in the summer?

Run a 6,000-BTU window-mounted air conditioner 12 hours a day for 30 days

Run a 6,000-BTU portable air conditioner 12 hours a day for 30 days

Leave the fridge door open

Open the windows and leave the air conditioner off

16 of 20

What’s the most affordable way to cool your home in the summer?

The correct answer is :
Run a window-mounted air conditioner
Obviously, not air conditioning at all is the most economical solution, but not the most comfortable one. The average energy cost for a window-mounted air conditioner that runs at least 12 hours a day can be as much as $27 a month, compared to $42 for a portable unit. A 6,000-BTU capacity is enough to cool a room.

16 of 20

DID YOU KNOW?

Did you know that air conditioning accounts for nearly 5% of household electricity bills during the summer? For maximum efficiency, experts recommend cleaning air conditioner filters regularly. You can also shut the doors to unoccupied rooms so the air conditioner doesn’t have to work as hard. Closing the curtains so the sun doesn’t heat your home during the day can also help cut costs.

Which device uses the least energy?

An old black and white TV

A desktop computer and monitor in sleep mode (14 hours a day, 365 days a year)

A laptop in sleep mode (14 hours a day, 365 days a year)

None of the above

18 of 20

Which device uses the least energy?

The correct answer is :
None of the above!
A computer that is shut down always uses less energy than one left in sleep mode.

18 of 20

DID YOU KNOW?

Leaving a desktop computer and monitor in standby mode can costs up to $2.30 a year for electricity, compared to $0.92 a year for a laptop. If 30 students turned off their computer instead of putting it to sleep, they would save between $27.60 and $69 a year. Imagine if everyone at your school did the same! Now dream a little and picture an entire city following suit. When everyone pitches in, even little changes can make a big difference!

18 of 20

What is the most economical refrigerator?

A refrigerator with a top freezer

A refrigerator with a bottom freezer

A cooler

All of the above

19 of 20

What is the most economical refrigerator?

The correct answer is :
A refrigerator with a top freezer
Refrigerators with top freezers generally draw less power than models with bottom freezers. Wondering about the cooler? It might be okay for a day, but don’t forget that you have to replace the ice and to make ice, you need a freezer! Do you have a top or bottom freezer at home? And we don’t mean upstairs or in the basement!

19 of 20

DID YOU KNOW?

A refrigerator draws significant power to chill food. To prevent that cold air from escaping, make sure you close the door as soon as you have put something in or taken something out, even if you’ll have to open the door again a few seconds later.

What is the most economical way to do your laundry ?

Use a front-loading washer

Use a top-loading washer

Wash your clothes in a nearby river

I am a total fashionista and all my clothes have to be hand-washed

20 of 20

What is the most economical way to do your laundry ?

The correct answer is :
Use a front-loading washer
Front-loading models use less water and energy than top-loading models. They also spin-dry better, which cuts down on drying time. You wash all your clothes by hand? Cool, they must be really beautiful, but it must take forever! That kind of lifestyle isn’t for everyone. And the concept of washing clothes in a river is really not the idea of the century! (Well, it was the idea of last century, maybe!)

20 of 20

DID YOU KNOW?

On average, ENERGY STAR® certified clothes washers use 25% less energy and 45% less water than traditional models.
