From our flat by the shore, the early morning view of mountains over Sagami Bay is less vivid than one week ago, when it was very cold and the air was clearer. Spring is definitely coming to town.
The main issues are taps and electrical outlets. Do we unplug everything completely when it’s not being used? We’re rushing to catch the train to the office in the morning. It is impossible! We do not!
This was my frank opinion toward this particular energy diet suggestion. But, I understand rationally that we must do this diet as well as we can, and we must be using a huge amount of unnecessary electricity.
I thought I must find smart equipment that help us produce the same results as unplugging devices manually. Wow, there are many terrific devices in the market I have never noticed.
By the way, have you ever counted how many appliances connect with outlets in your house? I had never done it, but I did. It is 37 as follows:
Automated lavatory basin
Flat panel TV set
Floor stand light
Desk top light
Desk top pot warmer
Independent hard disc
2 mobile cradles
2 air conditioners
2 spot heaters
3 desktop lights
Almost all of these electrical taps are kept flowing 24 hours a day. We also have a couple of interconnected systems such the TV, video player and DVD player that we use just certain hours in a day. Our PCs and relative peripherals are another example.
I bought some smart devices in the shop as follows:
Buying the wattage calculator was worthwhile. This one indicates current flow as kilowatt hours, consumption of CO2 as kilograms, cost per hour and total cost. I put this one on TV system outlet from midnight to 7 o’clock in the morning without using the TV. This seven hours of consumption was 0.06 kilowatt hours, 0.03 kilograms of CO2, ¥1 (1 cent) and ¥0.2 (.2 cents) per hour. It may not seem like a lot, but 0.03 kilograms × 50 million households in Japan equals 1,500 tons of CO2 consumed every night in one country without doing anything.
Then I checked meter time to time after this. What I found is that average usage of TV set for 5 days cost ¥0.3 (.3 cents) per hour. Approximately 2/3 of electricity we spent was when we were not watching TV. Having this confirmed by the figures, we could not let the situation stay as it was. Now we have a power strip with a switch connected to the outlet, which is a much more convenient way for us to turn off all the appliances connected to the TV.
For the PC, there are more peripherals connected. The PC-synchronized strip is smart. This device remembers the difference of current between on and off. When we start to use the PC and peripherals, all the needed power is supplied. But when we turn it off, the power supply is automatically cut. I used this for our floor heater as well.
I don’t have perfect measurements on the results for these devices, but I am seeing a visible reduction in waste. And so I’ve learned another method of energy-dieting.
