Modern homes in Nelson use far more electrical appliances than ever before, and as a result, much more power is required to be able to run the average home. Advancements in insulation and modern technology have gone a long way towards making the absolute most of our power usage, but when it comes down to it, there are still several ways that we can reduce our power usage. The following is a brief look at how much energy is required to run an average home, as well as some of the ways to minimise the amount you are using.
Obviously, the amount of power it takes to run a home will vary considerably based on the way you live and the amount of electrical appliances, temperature control and so on that you use on a regular basis. It could also depend upon:
how big your residence is
the number of people living there
the type and number of appliances
when and how appliances are used
whether you have a pool, spa, air conditioner or other energy-hungry devices
the climate you live in (and therefore whether you need to use more heating than other places)
COMMON APPLIANCE POWER USAGE
It’s relatively easy to figure out how much electricity your appliances use if you know their wattage. The wattage is usually printed on the appliance or its packaging, and is followed by a ‘W’ for watts or ‘kW’ for kilowatts. This will tell you how much electricity the appliance will use for each hour that it is running. Here are some examples to help you get an idea of the amount of energy popular electrical items use.
Light bulb — A 100 watt light bulb would use 1 kWh in 10 hours
Electric oven — Set at 180C for 1 hour, an electric oven uses around 2 kWh
Crock pot — Set at 95C for 7 hours, a crock-pot uses around 0.70 kWh
Toaster oven — Set at 180C for 1 hour, a toaster oven uses 0.33 kWh
Microwave oven — Set on High for 15 minutes, a microwave oven will use 0.36 kWh
Electric oven (convection) — Set at 165C for 45 minutes, an electric convection oven will use 1.39 kWh
Refrigerator (pre-1976) — 2200 kWh
Refrigerator (1992) — 1100 kWh
CEE Tier 3 refrigerator — 425 kWh
Desktop computer — 60-250 watts per hour
Desktop computer (on sleep mode) — 1-6 watts per hour
Laptop computer — 15-45 watts per hour, or 72 kWh per year
LCD monitor (20-24” — 18-72 watts per hour
Washing machine (hot/warm water setting) — 4.5 kWh per load
Washing machine (cold water setting) — 0.3 kWh per load
Television — 200 watt TV used for 6 hours = 1.2 kWh
Fan — 2400 watt fan used for 8 hours = 19.2 kWh
Phone charger — charging a phone for a year = 2kWh
The average Nelson house uses 18 kWh per day, and 6,570 kWh per year.
While the volumes may vary considerably, on average use 38 per cent of their home energy on heating and cooling, 25 per cent on water heating, 16 per cent on electronics and appliances, 7 per cent on fridges and freezers, 7 per cent on lighting, 4 per cent on cooking and 3 per cent on stand-by power.
ELECTRICITY SAVING TIPS
Considering that humans lived for thousands of years without electricity and survived just fine, it is incredible to see how addicted to electricity people have become. Most of us feel lost in a blackout.
But electricity isn’t magic, and it requires a lot of natural resources to make it work. So conserving energy is not only good for your power bills, it will help reduce the carbon emissions that we are releasing into the atmosphere.
There are plenty of easy ways to be responsible with your power usage and conserve energy in your home.
Here are a few of the things you can do to reduce your home’s power usage:
Wash your clothes in cold water
Set your computer to automatically switch to ‘sleep’ mode when not in use
Make better use of natural light
Watch less television
Take shorter showers
Re-insulate your home
Minimise your air-conditioning use
Switch appliances off at the wall when they aren’t in use
Use a lamp instead of a main light when you only need a small amount of light
Use energy-saving bulbs, like compact fluorescent globes
Always turn off lights in rooms you aren’t using
Use an electric kettle to boil water rather than the stove
Only run the dishwasher when it’s full, and use the economy cycle where possible
Dry clothes naturally rather than in the dryer where possible
Dress appropriately for the seasons, rather than immediately turning to air conditioners or heaters
Insulate your roof
Set your fridge to 4 or 5 degrees and your freezer to between -15 and -18 degrees
