Just like recycling, I was not too impressed and very surprised by the Japanese approach to energy consumption.
The climate does not help but overall everyone uses air con and heating full on and year round. In the winter, Japanese feel the cold much more than westerners and it is common to find offices heated to 26/27!! in the summer, the heat is tremendous so aircon go in offices 24/7 and in houses too, usually, from August, the government displays signs that we should keep aircon during night time too to avoid “natsubate” – heatstroke that takes many people to A&E every summer time
with the ageing population, those phenomenons will only accentuate. However, renewable energy is absolutely not on the agenda. Coal remains the main supllier as the cheapest, followed by nuclear power, sadly very famous after 2011 disaster
