The Little
Energy
Saving Book
Saving energy is easy,
if you know how
There are lots of ways to reduce your energy consumption. Simple, little
steps you can take that will mean big savings for both the environment
and your household finances.
This brochure shows you how much energy different parts of your home
use, and where the most common energy thieves are hiding. You’ll also
find some straightforward tips that will help you use the kilowatt-hours you
actually need – and no more. And all without cutting back on your comfort!
Did you know that it only takes three weeks to change habitual behaviour?
And there’s no time like the present to start!
Once around the sun
This is how much energy we use over the course of 365 days.
A household does the laundry 200 times a year, on average.
That costs around SEK 300.
The heat you and your family give off is known as free excess
human heat. You can generate an extra 2,000 kWh/year! That’s
worth SEK 3,000!
A 40 W light bulb that is on all year consumes 350 kWh.
That costs SEK 525.
The refrigerating unit in older fridges and freezers runs for a
total of 8,500 hours per year, which costs a total of SEK 2,300.
Newer models run for 5,000 hours and cost SEK 850.
A 6 W low energy light bulb consumes 53 kWh over the same period
of time and costs SEK 79.
One person uses an average of 32,000 litres of hot water per year.
It costs around SEK 1,670 to heat that water (to 40°C).
Devices in stand-by mode account for a massive 2%
of the entire country’s energy consumption
How much energy does
a house use?
The energy consumption of an average apartment is around 2,500 kWh/
year, which equates to about SEK 313/month*. The chart below shows
you a breakdown of household electricity consumption between different
areas. Approximately 500 kWh/year (ca. SEK 60/month*) should be added
to this total for apartments with their own laundry and drying facilities.
The energy consumption of an average household (detached or terraced)
in Sweden with direct electrical heating is around 25,000 kWh/year.
This equates to around SEK 3,125/month*.
The chart below shows you a breakdown of household electricity
consumption (excluding heating) between different areas. Our energy
saving tips in this brochure are shown for each of these areas.

Heating
Hot water
Heating accounts for around 55% of a household’s energy consumption.
Which means there is considerable potential for saving, particularly
during the cold months of the year. Read on to find out how you can save
significant amounts of energy – without freezing while you do it!
Hot water accounts for approximately 20% of a household’s
energy consumption. You can influence both the temperature and
amount of water used by changing your habits and replacing hot
water system components.
Air quickly and cleverly
A quick blast of through-draught is much more effective than leaving
windows ajar.
Don’t put things in front of the radiator
Putting something in front of the radiator stops the heat getting out into the
room. And if your radiator is blocked by furniture, it can fool the thermostat
into thinking the room is warmer than it actually is, at which point the
radiator will switch off. Yes, you’ll use less energy, but the room will feel cold.
Turn the indoor temperature down a degree
Turning the indoor temperature down by just one degree Celsius reduces
your energy consumption by around 5%. Which, for the average house,
means saving around SEK 1,000 per year.
Measure, seal and close
Use thermometers to measure the temperature at different points
throughout the house. Seal draughty windows and outer doors.
Close doors to colder areas.
Shower or bath?
You use the same amount of water in a shower lasting 12 ½ minutes as you
would if you ran a bath. If your shower lasts longer than this, you’d actually
save energy by taking a bath instead.
Short showers
Turn the shower off when you’re soaping up.
Switch to water-saving shower nozzles
This means you halve both the amount of water used and the cost
of heating it.
Replace worn washers immediately
Dripping taps can leak 500 kWh (SEK 750*) per year – money and energy
that could be much better spent.
Use a plug or a basin when you wash the dishes
That way, you avoid pouring hot water down the drain.

which corresponds to the variable component of the electricity price.

fridge & freezer
Cooking
Cooking accounts for around 16% of a household’s electricity
consumption. With the right equipment and a few changes to
your habits, you can make savings here, too.
Kitchens use a lot of energy. It may pay you, long-term, to replace old white
goods such as fridges and freezers. These units are running 24/7 and can
use a lot of electricity unnecessarily. But it’s still possible to be
energy-smart without buying new units: here are a few suggestions.
Keep your fridge and freezer at the right temperature
Set your fridge to +6°C and your freezer to -18°C. These temperatures
are all you need to ensure that your food is stored safely and you’re using
energy efficiently.
Clean the back of the fridge
A dusty condenser can increase your energy consumption by 25%.
Only wash dirty dishes
Try out different dishwasher settings to see how long a programme you
actually need. After all, why wash clean dishes?
Check whether the fridge door seal needs replacing t
Close the fridge door with a thin piece of paper between the door and
the body of the fridge, then slowly pull the paper out. If you don’t feel any
resistance, then it’s time to change the seal. This is a quick and easy way
of improving an old fridge’s energy efficiency.
Run the dishwasher full at the right temperature
Use a lower programme temperature – the results are often as good as at
higher temperatures.
Always put a lid on the pan
This reduces your energy consumption by up to 30% when
boiling a pan of water.
Don’t use pans with an uneven base
Because an uneven base can increase energy consumption by up to 25%.
Use pans that are the same size as the burner
If the diameter of the pan is just 1cm smaller than the burner, your energy
consumption can increase by up to 20%.
Thaw food in the fridge
This takes less energy than using the microwave. The microwave is a good
alternative, however, if you want to heat or cook smaller quantities of food.
Extractor fans
Don’t use the extractor fan for longer than necessary – it also extracts
large amounts of heated indoor air.
Let hot food cool
Putting hot food in the fridge forces the refrigerating unit to work harder
than it needs to. Allow the food to cool to room temperature before putting
it in the fridge or freezer.
Lighting and
electrical devices
Washing machine
& tumble drier
We have more electrical devices and lamps in our homes nowadays
than ever before. If you want to avoid unnecessary energy consumption,
a number of these can easily be replaced by energy saving alternatives
and used slightly more efficiently
There are a few simple things you can do to make a real reduction in
your energy consumption, but still get a really clean wash.
Switch to energy saving bulbs
LED, halogen, or low energy bulbs are the best alternatives and can have
a huge impact on a household’s energy consumption. An LED bulb, for
example, uses only 20% of the electricity used by an ordinary light bulb. .
Turn lights off
Only leave the lights on in rooms when you really need to.
Avoid stand-by
You can save up to 500 kWh (SEK 750*) per year by turning a device off
completely. The easiest way to do this is to connect the devices to an
extension lead with a contact breaker.
Turn off the towel rail
It might be a good idea to install a timer that switches it off automatically.
Disconnect the charger from the socket
The charger will continue to draw a current as long as it’s connected to
the power socket. This is true of all chargers, whether for a mobile phone,
toothbrush, or whatever. The charger can, furthermore, overheat and pose
a fire risk.
*This figure is calculated using a price of SEK 1.50/kWh, which corresponds to the variable component of the electricity price.
Run the machine full at the right temperature
Running a machine full might seem obvious, but you might also like to try
lowering the wash temperature. In the vast majority of cases, your clothes
will be just as clean if you wash them at 30°C as they will at 40°C. There are
also a number of special detergents designed for low temperature washes.
Replace old washing machines and tumble driers
A new washing machine will use less energy and less water. Tumble driers
use up to four times as much energy as washing machines, but the newer
models are more energy efficient than the old ones.
Hang your clothes up to dry
Spin the clothes in the washing machine to remove as much water as
possible, and invest in a drying rack so you can still hang clothes up to dry
in the winter months. If you do the laundry 200 times a year, this could save
you SEK 1,500 per year.
Always use the energy saving programme
That way, you’ll know that your machine is using energy as efficiently
as possible.
