Top Energy Saving Tips
1. Replace regular light globes with energy saving lamps – they use about 20% of
the energy and last 6 to 8 times longer. CFLs are available in two broad colour
options - warm white and cool white. Cool light is suitable for visual tasks
because it produces higher contrast. Warm light is better for living spaces
because it is more flattering to skin tones and clothing. Energy efficient bulbs are
available in supermarkets and hardware shops.
2. Use energy efficient lamps for exterior lighting, with timers or light sensors to
switch them on and off as required.
3. Don’t underestimate the power of daylight – use skylights and well-placed mirrors
to reflect natural light and help reduce costs.
4. New LED lights are even better than compact fluorescent lamps, and are
becoming more readily available.
Heating and cooling rooms
1. Use a thermostatically controlled heater to regulate the room temperature. 2. Insulate the ceiling to improve insulation and the regulation of the room
3. Wear clothing that is appropriate for the weather to save switching on air-
conditioners or heaters.
4. Keep room doors closed so air-conditioners or heaters do not have to work too
1. Use appropriate cooking utensils For example use toasters rather than the grill to
make toast, and use an electrical kettle, not an ordinary saucepan on the stove to
boil water. You will use about 50% less electricity
2. Use pots and pans with a flat bottom so that the base makes full contact with the
3. Only boil as much water as you need when making a hot drink – kettles use lots
4. Consider using a pressure-cooker for soups and stews. By building up steam
pressure, it cooks at a higher temperature, which considerably reduces cooking
time and therefore energy consumption.
5. Food cooks more efficiently in ovens when air can circulate freely. If possible,
stagger pans on upper and lower racks to improve airflow.
6. If you have a self-cleaning oven, use the feature just after you've cooked – that
way, the oven will still be hot and the process will require less energy. 7. Use the microwave where you can.
1. Swapping older top-loading washing machines for more efficient front loaders
can make a 30 per cent energy saving and are very effective at lower
2. Wash bed linen at 60?C, not 90?C. The sheets will still be perfectly clean. 3. Using a 40?C wash cycle rather than 60?C equates to a 30 per cent electricity
4. Make up a full load before washing.
5. Skip the washing machine's pre-wash cycle if your clothes are not particularly
dirty. This will use up to 20% less electricity, and cause less wear to the
6. Avoid using a tumble dryer - hang clothes up to let them dry naturally. But if you
do use a tumble dryer, do loads back to back - dryers take time and energy to
reach the right temperature.
Fridges and Freezers
1. Buy an energy efficient fridge-freezer - it could give you huge savings on your
electricity bill every year. New, energy-efficient refrigerators use half the energy
of standard fridges from the early 1990s. The most efficient refrigerators are over
and under fridge-freezer combinations.
2. Manual defrost freezers are generally more efficient than automatic defrost
models if they are properly maintained. The freezer should be defrosted if ice
build-up is thicker than 5mm.
3. Vacuum the coils in the back of your refrigerator twice a year to maximize
4. Make sure the fridge is not positioned next to the stove, dishwasher or exposed
to direct sunlight, which will make the appliance work harder. 5. If your refrigerator has an energy-saver (anti-sweat) switch, it should be on
during the summer and off during the winter.
6. Make sure the seals around the doors are not cracked or torn, which will mean
the cols air leaks out.
7. Freezers work best if they are full – if yours is on the empty side, put a building
brick or two inside. These will become very cold and act like a cool box brick
meaning the freezer won’t have to work as hard.
1. Modern dishwashers are almost always more energy efficient than doing the
dishes by hand if they are used responsibly.
2. Only start the dishwasher when it is full and loaded correctly. 3. Scrape leftovers into the bin before loading plates.
4. There is no need to pre-rinse under running water – the high temperature and
pressure will remove stubborn stains during the cycle.
5. Use the economy setting wherever possible.
6. Use rinse aids to ensure the dishwasher works at maximum efficiency.
1. Geysers account for approximately 40 per cent of the household energy bill.
Set the geyser temperature to 60 degrees. There will be a noticeable drop in
the electricity bill, but no noticeable difference in temperature. 2. If you can afford it, install a solar water heater.
3. Insulate both the geyser and pipes to keep the water warm – the savings in
electricity make it a good investment.
4. Allowing hot water to pour out of taps and down the drain is wasteful. 5. Take a shower instead of a bath to save on hot water and use an aerated
(low-flow) showerhead to control the amount of water used.
6. if you have an old cistern, put a brick in it. This will mean you use less water
that has gone through a very energy intensive process before it gets into the
1. Unplug DVD players and TV’s at night. Or plug them all into a power strip
which can be switched on and off conveniently. Sixty per cent of electricity
consumed by such appliances is done so while they’re idle, powering light
displays or utilizing “instant on” features.
2. Unplug “wall warts” - plugs attached to a black transformer box, like cell
phone chargers. Whether the device is being used or not, if it is plugged into
an outlet, it is consuming energy.
3. Turn off printers, copiers and fax machines when they are not in use – don’t
rely on the sleep mode. Using power management on your desktop computer
could save 900 kilowatt-hours a year. This amounts to 3,300kgs of carbon
4. Printing is often the most energy intensive step of computer work – do your
editing on screen and print only what you need.
1. If you have a gas furnace for home heating, change the filter monthly to save
2. Be sure that all cooking burners are burning with a blue, cone-shaped flame.
A yellow flame indicates clogged air inlets or burners that need adjustment or
the valves need cleaning.
3. Check the seal on your gas oven door. Gaps or tears in the seal let heat
escape and waste energy.
4. Keep the hobs and the reflectors on stove tops clean and debris-free - they
will reflect the heat better, and you will save energy
1. Avoid stop-start driving. Rushing up to a robot and pulling off too quickly
means you will use a tank of fuel 5 per cent more quickly. 2. If you own more than one vehicle, drive the one that’s most fuel efficient
3. Switch from cross to radial ply tyres. Radial ply tyres have less rolling
resistance and last longer.
4. Stick to the city speed limits – 5-10% fuel can be saved. On highways it’s best
to travel 100 to 110km/h. As much as 33% fuel can be saved driving at these
5. If possible, take advantage of car lift clubs for schools and work, and ride-
share programmes – this cuts fuel costs in half and saves on vehicle wear
6. Stagger work hours to avoid peak rush hours – you will spend less time in
traffic and consume less fuel.
7. Ensure that your vehicle is well maintained at all times.
8. Check that there are no holes in the exhaust pipe.
9. Make use of public transport.
10. For short journeys consider walking or cycling.
