Summer 2012 Conservation Tips

| No Comments
Setsuden - power conservation season - begins on Monday.

This summer there will be no nuclear power generated at all, which means 11.8 gigawatts less to use. It's made up for in part by coal (an unclean nightmare) and small increase in renewable sources, but the upshot is we have a little less power this summer than last. And they are predicting a scorching hot summer to come. So we are being asked once again, to limit our power use. 

Last summer businesses were mandated to reduce consumption by 15% but this year there is no specific target in Tokyo and businesses and households are equally responsible for saving electricity between 9 am and 8 pm. 

From a household perspective, where can we save? In 2011 we all invested in low energy lightbulbs and electric fans. What are this year's recommendations?

According to this guide from METI, the Top 10 things we can do:

  1. Set aircon to 28 degrees
  2. Close blinds and curtains during the day
  3. Turn off the aircon and use a fan
  4. Set fridge from high to medium and do not overfill it
  5. Turn off lights during the day
  6. Use TV's energy saving mode and/or reduce the brightness of the display
  7. Turn off toilet's warm water wash feature
  8. Unplug the toilet washlet and other unnecessary appliances
  9. Cook enough rice for the day before 9 am using the timer settings on your rice maker
  10. Turn off remote controlled devices from their on-board power switches. Unplug if possible

And other good ideas:
  • Clean the aircon filters twice a month
  • Use one aircon unit instead of two where possible
  • Ensure sufficient ventilation space around the refrigerator
  • Load the washing machine to 80% full
  • Run laptops on battery power during the day and charge them at night
  • Use power saving modes on your computer
  • Boil water on the stove and store it in an unpowered vacuum pot
  • Replace the vacuum bags frequently
  • Mop or sweep during the day; vacuum at night
  • Leave the house during the day
  • Turn off appliances during the peak hours of 13:00- 16:00
