Electricity accounting or natural gas? 5

Electricity is less expensive than natural gas.

The calorific value of natural gas per square meter is 8,500 kcal, and the energy that can be converted into electricity per kilowatt-hour is kilocalorie, that is, the heat released by the complete combustion of natural gas is about 10 times (times) that of electricity completely converted into heat.

Whether you use natural gas or electricity in your home, there is a problem of thermal efficiency, that is, not all natural gas is burned to heat water, but also to heat air, heat heat, etc., and the same is true for electricity. Usually, the thermal efficiency of ordinary gas stoves does not exceed 70%, and considering the environmental problems of use, the actual thermal efficiency is about 50%. The thermal efficiency of electricity is much higher, for example, the thermal efficiency of induction cookers is above 90%.

If, the natural gas element, the electric element. Then it is not difficult to calculate that the cost of heating the same water with natural gas is twice that of electricity. However, it is important to note that this is only the cost of energy and does not include other factors such as safety, convenience, etc.

From the point of view of energy saving, it is better to use electricity.

Note: If you use electricity, then it is best to consider the thermal efficiency of your appliances first; If you use natural gas, it is best to choose a pot with good heat transfer, and you should pay attention to safety.

Boiling a pot of water with electricity is about yuan.

It costs about $1 to boil a pot of water with electricity and natural gas.

Natural gas and electricity are more cost-effective than natural gas.

Natural gas water is a little less expensive than electric water, if you can guarantee that there will be no waste. Assuming that the **4 yuan per cubic meter of natural gas, the electricity fee is yuan per kilowatt-hour.

Boiling 5 liters of water does not calculate the loss, it takes 450 kcal, and if you use gas, 450 kcal needs to consume cubic meters of natural gas, ** is yuan. If you use electricity, 450 kcal calories are thought of and need to consume degrees, ** is yuan.

In contrast, natural gas is more economical, but there is basically no additional waste in boiling water with electricity, and there may be a lot of unnecessary expenses if you don't pay attention to natural gas boiling water.

Precautions for using natural gas:

1. If you use natural gas in the kitchen, you must remember not to close the windows very tightly, and pay attention to opening the windows for ventilation to avoid causing some accidents. Because if the room is in a sealed state, the natural gas will produce carbon dioxide when burning, and the oxygen content will gradually decrease, and when the oxygen supply is insufficient, it will make people unconscious, and in severe cases, it will lead to death.

2. When using natural gas, especially in the kitchen to cook and cook with natural gas, someone must take care of it, and if you leave the kitchen, you must close the gas stove and valve. Usually also pay attention to the repair and maintenance of the gas meter valve, if there is a looseness or gas pipeline leakage, must be repaired in time, otherwise the consequences are very serious.

3. The gas pipeline should be replaced regularly when using natural high gas, it has a service life, if it is some hoses, it can not exceed two years, and it is found that there are aging or cracks to be replaced, and the problem of winding can not occur when installing the soft pipeline, which is easy to damage the pipeline. <>

Heavenly hands are amused with electricity. Natural gas needs to be liquid at high pressure to be transported efficiently, it needs to be transported with high-pressure pumps, and electricity must be used. Residential natural gas is basically vaporized after entering the city, and pipelines and storage tanks can maintain gas supply for a considerable period of time.

Therefore, unless there is a power outage in the entire city, a local power outage will not affect the civil gas**.

Natural gas: Natural gas refers to all gases naturally occurring in nature, including gases formed by various natural processes in the atmosphere, the hydrosphere, and the lithosphere (including oilfield gas, gas field gas, mud volcanic gas, coalbed methane, and biogenerated gas, etc.). For a long time, the definition of "natural gas" was a narrow definition from the perspective of energy, referring to a mixture of hydrocarbon and non-hydrocarbon gases naturally contained in the formation.

In petroleum geology, it usually refers to oilfield gas and gas field gas. Its composition is dominated by hydrocarbons and contains non-hydrocarbon gases.
