Water saving methods
1. Rice water can be used to wash vegetables, water flowers, wash your face, etc. In addition, washing your face with rice water also has special effects on skin care, which can be said to kill two birds with one stone.
2. Rinse the mop with soapy water used for washing clothes. When washing clothes, don't throw away the soapy water casually. It is best to pour it into a special basin for rinsing the mop and save it for rinsing the mop. This saves water and soap.
3. Water used for washing dishes can be reserved for flushing toilets. If the water is not too greasy, it can also be used to wash cloths. Because rags are the most used in the home, they are also the dirtiest. Cleaning often requires numerous washes and therefore consumes a lot ofa splash of water. So it's a good idea to use dishwater or soapy water from washing regular clothes to wash the cloth, which can save a lot of water.
4. After bathing the baby in the bathtub, the adult can continue bathing with the bathwater. There are many baths in summer. It is also a good way to save water when adults use the water to rinse the baby after daily bathing.
5. When washing your face, applying facial cleanser or scrubbing your face, turn off the faucet in time and do not let the water flow out by itself. If you see an open faucet that is not being used, turn it off immediately. I remember that the taps at school often broke and the water from the tap flowed out in vain. I found a brick to hold the faucet down so the water could stop.
Energy saving methods
1. Unplug allswitches and sockets before going out or going to bed (except refrigerators). You should know that the power strip that is plugged in also consumes electricity.
2. When using an electric heater to boil water for bathing in summer, the water temperature must be lowered because the water in the electric heater is very hot. You can take a shower with just a little heating.
3. Don't set the home air conditioner too low in summer. It is best to set it to around 26 degrees. This saves electricity and the temperature in the room will not be too low. is not harmful to the body.
4. Replace all light bulbs in the house with energy-saving lamps. Energy-saving light bulbs save more than half the electricity than ordinary light bulbs. Although they are more expensive, their durability is also much higher.
5. If you use an induction cooker to cook noodles, peanuts, etc. At home, don't wait until food is cooked and mushy before turning off the heat. When they are almost cooked, turn them off. turn off the power in time and cover it. Simmering for a while with the lid on can also make noodles, peanuts, etc. very cooked.
Use a microwave oven, electric stove, natural gas stove or other water boiling tools to boil the same amount of water (two to three hundred meters cubes), which is more energy efficient? (Urgent)
Solar power generation is the most energy-efficient and environmentally friendly means of generating electricity.
The new energy must meet two conditions at the same time: first, it is rich and will not be exhausted; second, it is safe, clean and will not threaten thehumans or damage the environment. There are two main types of new energy sources, one is solar energy and the other is fuel cells. In addition, wind energy can also be considered as a new auxiliary energy source.
The solar energy shining on the Earth is very enormous. The solar energy that shines on the Earth in about 40 minutes is enough to sustain the energy consumption of human beings around the world for a year. It can be said that solar energy is truly inexhaustible and inexhaustible energy. And solar energy is absolutely clean, no public nuisance. Solar energy production is therefore considered an ideal energy source.
Obtaining electricity from solar energy requires photoelectric conversion via solar cells. It is completely different from other electricity generation principles of the past and has the characteristicsfollowing characteristics:
① No risk of exhaustion
② Absolutely clean (no pollution
);③ No Limited by geographic distribution of resources;
④ Can produce electricity close to the place of consumption
⑤ High energy quality; ⑥ Easily accepted emotionally by users;
⑦It takes a short time to obtain energy.
Microwave oven: Electricity converts magnetic energy and magnetic energy heats water. What is thermal efficiency?
The electrical energy of an electric furnace is converted into thermal energy, and the heat is then conducted by convection to the water to heat the water. What is thermal efficiency?
Natural gas stove - Fossil fuel burns and releases heat, which is then conducted by convection to the water to heat the water. What is thermal efficiency?
But we need to know what energy ist converted into electricity? If it is also thermal energy production, the efficiency is very low, usually 35%, so I think there will always be energy losses through various energy conversions, and the most direct is also the best! But do natural gas stoves have to burn natural gas? Certainly, the calorific value of natural gas is 8500kcal/Nm3
