little things to save energy

On the first day of my energy saving practice, I searched some ways to save energy that would not reduce the quality of our lives, to be put into practice in the following week.

Tips1：Change Macbook to “energy saving mode”

Computers and televisions can be set to the right brightness and the right volume, and generally the settings menu of our home televisions have an “energy saving mode”, by using the “energy saving mode” can greatly reduce the brightness of the backlight fluorescent tub. This not only reduces power consumption, but also extends the working life of the backlight fluorescent tube.

Previously I always left the Macbook and Iphone in a normal state and bright screen when not in use, but for the next week I put it to sleep model and “energy saving mode” when not in use.“energy saving mode”

[Assuming that the 13-inch MacBook Pro is used for 8 hours a day and the remaining 16 hours are spent sleeping rather than idling, the electricity saved over a year is (3.03–0.16)*16*365/1000 ~= 4.2 kwh
According to the Greenhouse Gas Equivalencies Calculator, 4.2 kwh of electricity produces approximately 1.8 kg (4 lbs) of CO2 emissions, which is equivalent to the amount of CO2 emitted by an average fuel car driving 7.2 km (4.5 miles).]

Tips2：Do not set the temperature of the air conditioner too low.

Do not set the temperature of the air conditioner too low. The lower the air conditioning temperature temperature the greater the power consumption. In fact, there is no need to set the temperature too low, the appropriate temperature is good, the human body is generally comfortable with the temperature of 25 ° — 27 °, and the appropriate temperature does not make the temperature difference between people entering and leaving the room too large.

Tips3： Let hot things cool before taking them into the fridge

It is best to let hot things cool before taking them into the fridge. If you want to create ice cubes or frozen drinks, it is best to first also cool the drinks to room temperature first and put them in the fridge before going to bed. Because you won’t be opening the fridge all the time at night, power consumption is reduced.

Tips4：soak the clothes in water before putting into washing machine

Before washing clothes in the washing machine, you should soak the clothes in water with washing powder for 20 minutes, so that the stains are easier to wash off, and then use the washing machine to agitate, which can reduce the spinning time of the washing machine.

Start saving energy by doing small things and forming habits that will last for a long time. I think this is a very meaningful action.
