Pay attention to turn off the lights. Use efficient and energy-saving light bulbs. The U.S. Department of Energy estimates that 400 million tons of carbon dioxide can be prevented from being released only by using energy-saving light bulbs instead of traditional ones. It is best not to switch the energy-saving lamps for a short time, because the energy-saving lamps consume the most electricity when switching. Don't leave what you can finish during the day to do at night. Wash clothes and do homework before dark. Going to bed early and getting up early is good for health, environmental protection and energy saving.

2. Low-carbon cooking

Try to save energy in the kitchen. When cooking oil is heated, it produces carcinogens, which leads to the indoor environment pollution by oil fume. Reduce cooking and cook more vegetables. Don't fill the rice cooker and kettle too full, otherwise the soup will overflow after boiling, which will not only waste energy, but also easily put out the stove fire and cause gas leakage. Adjust the combustion range of the flame so that it does not exceed the outer edge of the bottom of the pot to obtain the best heating effect. If the fire in the pot is small, the flames burning around the bottom of the pot will only be wasted. Cook and stir-fry at home, just eat and don't stir-fry. When you see discarded food on the road, you can pick it up and feed it to wild dogs, wild cats, birds and other small animals.
