Have you heard of “Earth Hour” – when hundreds of millions of people all across the planet turn off their lights for one hour, on the same night?
It’s all happening tomorrow. As confirmed map fanatics, we decided we had to create a map to do our part for the cause!
Earth Hour is all about appreciating the world we live in, and doing our part in preserving our planet’s future. From extreme water changes like flooding or drought, loss of species, to deforestation, Earth Hour is about more than saving an hour’s energy – but about realising how what we do, and the energy we consume, affect the world.
With all this in mind, our maps today explore global energy consumption.
We’ve mapped two years, two decades apart*. The first map (above) illustrates global energy consumption in 1990, measured in kilowatts per hour (kWh), per capita.
(To give you some context around the KWh measure, using a 100-watt lightbulb for 10 hours equates to 1kWh.)
Most countries used 5,000-10,000 kWh per inhabitant. Major energy producers Norway and Iceland used a bit more – an average of more than 15,000 kWh per inhabitant.
Our second map (right) shows gliobal energy consumption nearly 20 years later, in 2009.
You can clearly see that overall energy consumption levels rose during this period. While it is generally accepted that an emerging economy like China would have consumed significantly more energy during this period, it’s interesting to see that Spain, Italy and Saudi Arabia also jumped up to the next level of consumption.
Perhaps most importantly, does the pattern of rising global energy consumption encourage you to switch off for an hour on 31 March?Learn more about Earth Hour
