What are the power saving measures that can be done by telework?Verify PC -related electricity bills !! - Considering power saving at home (Part 3)

The notebook PC was much more energy -saving than the desktop PC

　I use a MacBook Pro when I go out.

　More than 10 years ago, when I lived in Nagoya and had many opportunities to travel to Tokyo, I used a lot of notebook PCs (at that time Let's Note), and used on my home sofa when there were no tablets.Recently, the sofa has a tablet, and the number of going out has decreased, so MacBook Pro has few turns.

　Some acquaintances use the same laptops on their homes and on the go, and many salaried workers in telework will use laptops.The power consumption of my MacBook Pro is 30-40W at startup, and an idling state of about 8-10W.The power consumption when operating normally is about 15W on average.

　If you copy a file, it will increase a little and go up and down at about 18W, and in the video conversion, it will rise to nearly 35W.0 during sleep.7W, shut down 0.It will be 6W.The difference between sleep and shutdown is small, all of which consume less power than desktop PCs.

　15W of average power consumption.Calculate the electricity bill 0.38 yen/time.In the case of 8 hours and 12 hours per day, I calculated the electricity bill for one day and one month, respectively.
