节约能源从小事做起.
When you are using the computer, please properly turn down the brightness of the monitor. By turning down the brightness, you could save about 30 kilowatt-hour(kw-hr) electricity annually for a desktop computer, equivalent to reducing the emission of 29 kilograms(Kg) of carbon dioxide; similarly an annual saving of 15 kw-hr of electricity or equivalently a reduction 14.6 Kg of carbon dioxide emission to the air a year for using a notebook computer.
To conserve energy starts from doing the trivial things.
