So how much energy does the average person use every day? Swiss scientists worked the numbers and came up with a model for each country’s total energy consumption back in 1998 and divided it by the number of citizens. The result showed that as a planet we average about 2000 watts continuously (17,520 kilowatt-hours per year). That’s equivalent to leaving the hairdryer on 24/7!
Of course, the model didn’t just include electric use, but rather all energy use translated into watts. So our 2000 watts include all the energy used to make our lives go round: the energy used to produce and deliver our food, our gadgets, the fuels used to run our vehicles, etc, they even included the energy used to run sewage plants and other “invisible” things that make our everyday what it is.
So the 24/7 hairdryer doesn’t seem a lot for all this after all? Unfortunately 2000 watts was the planet average. 2004 figures estimate the average European uses three times the average (6000 watts) and the average American twice that again (12,000 watts). Norwegians weigh in at a hefty 8,000 watts.
Not surprisingly the model paints a world of energy haves and have nots, but more alarmingly gives us a reminder how energy use will grow in the future as nations like China and India continue their rapid development. And unfortunately most of the energy we use today comes from limited, non-renewable, carbon-emitting sources. In addition to the impact on global climate there is the risk of conflict as resources grow scarcer.
Along with the model came a vision of a 2000-watt society. A world where most people limit their energy use to 2000 watts. The model aims to more evenly redistribute energy as well as establish a sustainable level of energy usage for the future. Technological advances play a major role in reaching this goal, such as passive house design, zero-energy buildings, low-emission vehicles, etc.
