How Much Power is Needed to Run an Average Home in Nelson?

Posted on 28 August, 2016 at 18:40


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
