Mobile phone charging a 0.02 kwh per year in places fee 730 million

Although the show has been completed, but still power consumption

This reporter to verify the reader's energy conservation issues in the electrical city yesterday conducted three experiments --

Experiment shows: readers, mobile phone charging when the charging indicator light turns green will continue to continue charging power, it is a waste of energy; and some people think that mobile phone battery is full of electricity will automatically stop the absorption of electricity, so there is no waste.

In order to prove that these two statements which is more scientific, the reporter did the experiment.

Methods: journalists were selected more representative of the NOKIA and Samsung mobile phone each one as experimental samples, while the two part is inserted in the mobile phone charger, then the two chargers were received a meter, such as mobile phone battery, it will be the consumption of electric energy meter record yourself down, and continue to focus on the two meter in the end is connected with the mobile phone mobile phone charging, with scientific proof of the experiment.

Experimental procedure:

Step 1: two mobile phones are inserted on the charger to charge, and the two chargers are connected to the two meter.

Step two: when the end of the two cell phone charging, recording its consumption of electricity, and continue to observe the work of the two meter.

Step three: the mobile phone display after charging for 1 hours, 2 hours, 3 hours and three time points respectively record pointer position, the two meter Taiwan each index record, and calculated the energy consumption of two charger.

Experimental data:

After the calculation, from the beginning of the two phones have been charged to the end of the charge, about 3 hours or so, their respective consumption of electricity is about 0.01 degrees. The charge from the phone to complete until 3 hours after the completion of the phone charging, they continue to charge the consumed power is also about 0.01 degrees. In other words, if you do not unplug the charger after charging the phone, but let it continue to charge, then it consumes 3 hours of electricity can be completed once the charge.

Experimental summary:

The reporter then calculations, it is understood that at present there are about 200 million mobile phone, if every mobile phone in every 2 days, every time a charge at night continuously charging for 9 hours per charge calculation, then will consume about 0.03 kwh, a year down the total power consumption of the mobile phone has reached alarming 1 billion 100 million degrees! If you remove the normal charge of 3 hours per cell consumed by the electricity consumption of 0.01 degrees, the annual consumption of electricity in the country's 200 million mobile phone is about 730 million degrees!

The reporter learned that through online search, the current generating capacity a year in Gezhouba Dam power plant is about 17 billion kWh (degrees), that is to say, electricity accounted for Gezhouba Dam power generating capacity throughout the year all mobile phone charging waste 4%. Really don't try not to know, a try to jump! Seeing so much energy wasted, it seems that we really need the public mobile phone charging process of the waste of attention, if these savings in electricity, enough of our people, how many cool summer flushing blowing air conditioning!
