Theoretical physicist, 27 (N.Z.)
I like to think I saved a lot of energy, probably more mental than actual, by turning off the TV and no longer exposing myself to the total panic being spread by foreign news agencies. On a more mundane and useful level, I've been wearing extra layers to reduce the necessity of heating.

One should: eat all food that is offered; turn off the air conditioner if not needed; reduce the amount of garbage; unplug electric devices in order to avoid standby operation; switch off car motor at traffic lights; use clothing as long as possible.

I turn my lab computer off at night, use stairs instead of elevator. However, as a friend advised, the best way to save water is to bathe in pairs, sleeping with friends saves energy.

My husband and I have always been very sensitive as far as energy use is concerned. Now we try to go to sleep earlier, we switch off electricity as often as possible and use "kotatsu" (heated table) instead of the air conditioner.

I came to Kashiwa yesterday. I try to sleep with the heater turned off. I even try to keep it turned off all the time. I don't use the heated toilet (seat) because it's a waste of energy.

In this difficult time I don't use the refrigerator because it's still cold. Additionally, I keep the heater turned off. In my opinion everybody should contribute to energy saving in the affected areas of Japan.
