Having a bad hair day and getting cold feet
When the author of our Energy [R]evolution, Sven Teske, was in Seoul in February, he complained. It was -15 degrees celcius outside, and his hair was bad, his feet cold.
"In Korean buildings you heat rooms by putting the air conditioning systems near the ceiling. But this means that all the hot air stays at the top of the room, and it takes a huge amount of energy to get the heating all the way down to your feet. So while your head is hot and your hair dries out, your feet are usually cold."
This type of heating system, and with little or no insulation, says Sven, means that South Koreans use more electricity than almost any other country in the world - at a massive 8687kWh each. This is 15 times the average African, and even 20% more than a German person (Sven is German).
But there is hope. The Energy Revolution scenario for Korea, that we launched this week, shows that if Koreans changed the way we heat our buildings – and insulated them, we could save a huge amount of energy.
By 2020, South Korea could have reduced our energy consumption in heating by 15% - and to achieve this we could be using much better ways of heating our buildings and be using renewable energy to do it.
So if you want warm feet and better hair in the Korean winter, think of an Energy Revolution.
