Record power consumption
Power consumption in Japan reached a record of nearly 3.42 billion kilowatts on Tuesday as soaring temperatures prompted residents to switch on air conditioners.
The Federation of Electric Power Companies of Japan announced that the power usage for the 10 power companies the federation represents reached 3,419,917,000 kilowatts, breaking the previous record set in 2001 of 3,392,200,000 kilowatts.
As Leon, our web guru over at Alishan Organic Center pointed out to me today, the heat wave during the past 10 days couldn't have come at a worse time, as 7 nuclear reactors in Niigata prefecture are closed because of earthquake damage.
The graph shows how power companies deal with power surges during the day. Basically, more oil is used during peak hours starting around 9:00 AM. If Japan introduced daylight saving time, energy consumption could be drastically reduced.
