How Much Energy Does YOUR Home Consume?
Do you know how much energy your home consumes in a year? Some might say that it doesn’t bear thinking about, but did you know that, in 2014, household electricity use in the UK dropped under 4,000 kW/h for the first time in decades? So, how much energy does your home consume and how can you reduce your consumption even more? Read our LED Monkey blog to find out…
In a comparison with other counties that participate in the OECD (Organisation for Economic Co-operation and Development), the UK's electricity consumption doesn’t seem all that bad.
US Tops the Energy Consumption Chart
As you'll see from the graph below, homes in the US consume an average 12,300 kW/h each year. In Canada, the figure is around 11,000 kW/h/year, while Australian homes consume 7,000 kW/h/year. This is probably due to the fact that UK homes are quite a bit smaller and they're primarily heated using gas.
Also, unlike the US and others, UK homes aren't generally equipped with air-conditioning systems, mainly because it’s so bloomin’ cold already! Check out the graph below to see the average energy consumption in homes around the world.
In fact, UK homes are very similar to those in Europe as far as energy-consumption is concerned, with an average annual usage of around 3,600 kW/h. However, this figure is more than double that of Chinese homes which average 1,500 kW/h per dwelling, and triple that of India where homes average only 1,100 kW/h each year.
According to figures provided by the World Energy Forum, the lowest recorded average for electrified homes are those in Nepal (as shown in the picture, right) at a meagre 320 kW/h!
But just because the average UK home uses around 4,000 kW/h/year, that doesn’t mean yours has to!
It’s probably best to compare your own figures to similarly sized UK homes, so here’s a table illustrating the averages by home type:
You’ll notice that larger homes consume more energy, while mid-terrace houses and flats consume about 2,800 kW/h/year. End-terrace homes consume slightly more and semi-detached homes are next, followed by bungalows and detached houses which each consume up at 4,153 kW/h annually. Obviously, if your home has exclusively electric heating, your consumption will be much greater.
So how do we use electricity in our homes?
The graph below shows the estimated figures for 2014. It'll give you an idea of where all our precious energy is going.
TVs nowadays are much more energy-efficient than in the past and often use energy-saving LED technology.
Based on a daily usage of four hours a day, a 32-inch LED TV will consume only 50 kW/h/year, a 42-inch LED TV 80 kW/h/year, and a 70-inch screen will consume around 150 kW/h annually.
Modern fridges are much more energy-efficient than they used to be. A new A+ rated fridge, for example, will consume as little as 100 kW/h/year, while a tall A+ rated fridge freezer is likely to consume up to 200 kW/h/year. By comparison, a very large American style A+ rated fridge freezer can consume about 400 kW/h/year quite easily. The fridge pictured below does NOT come into this category, by the way!
While a computer’s energy consumption depends largely upon its size, modern laptops and tablets are designed to be quite efficient, depending on their batteries for much of their power. As such, desktop computers use around 150 kW/h/year, while laptops consume 30 kW/h/year and tablets even less at just 12 kW/h/year.
The Washing Machine & Tumble Dryer?
Of course it depends how often you do a wash, but the average electricity consumed by washing machines in the UK is 166 kW/h/year.
However, tumble dryers are a different kettle of fish entirely. Their average energy consumption is more than double that of their wetter counterpart at around 394 kW/h.
The other items in our little run-down consume the following:
- Electric cookers consume an average of 317 kW/h/year;
- Dishwashers consume 294 kW/h/year;
- Electric hobs 226 kW/h/year;
- Kettles 167 kW/h/year;
- Microwaves 56 kW/h/year;
- Hair dryers 20 kW/h/year.
How About Lighting?
As you'll have seen from the graph, lighting accounts for quite a large chunk of a home's annual energy expenditure. As such, it's wise to invest in the most energy-efficient type of lighting you can.
The amount of energy consumed by your lighting really depends on the type of light bulbs you're using.
For example, the average domestic light bulb is switched on for around two hours every day (or night). Here are the approximate amounts of power each type of individual bulb will consume over the course of a year, assuming each emits 700 lumens:
- An Incandescent Light Bulb consumes around 44 kW/h/year;
- A Halogen Bulb / Spotlight consumes around 31 kW/h/year;
- A CFL (Compact Fluorescent Lamp) consumes 9 kW/h/year;
- An LED Bulb consumes between 3 and 6 kW/h/year.
Due to the fact that they don't waste energy producing heat, LEDs produce light many times more efficiently than traditional incandescent light bulbs, so they really are the smartest choice of lighting for your home.
Not only that, they last a lot longer than all the other types of bulb, too. Indeed, with a lifespan that's between 15,000 and 50,000 hours, they can last anywhere from 10 to 20 years, meaning you'll have to shell out for replacements far less often.
