In terms of the economy of cooking with gas and electricity, cooking with gas is more cost-effective.
1. Price comparison
The price difference between cooking with gas and electricity is large. At present, the price of gas is generally cheaper than that of electricity. Especially in families who cook frequently, there are great advantages in using gas to cook.

2. Efficiency comparison
The efficiency of cooking with gas and electricity has its own advantages. Cooking with gas is fast and powerful, and can quickly reach high temperatures. The fires do not interfere with each other, and multiple dishes can be cooked at the same time; while cooking with electricity requires preheating time, and the heat is not as sufficient as gas. It takes longer to reach the ideal cooking temperature, and the efficiency is lower.

3. Service life comparison
Since gas stoves produce water vapor and acidic substances when working, long-term use may cause corrosion and aging, and gas pipelines and valves may also have aging problems. These problems require regular inspection and maintenance. The service life of electric stoves is longer, there is no such big aging problem, and only regular cleaning and maintenance are required.

4. Comprehensive comparison
From the above three aspects, although electric cooking has its convenience, cooking with gas is more cost-effective in terms of economy. Gas is cheap and has a shorter service life, but it is still more cost-effective. Especially in small and medium-sized families or families with large cooking needs, using gas to cook can also save energy costs.

In summary, cooking with gas is relatively more economical, but the choice of cooking method still needs to be made according to personal actual situation and needs.
