The difference between electricity and gas in a hot pot restaurant in Kunming lies in the cost and price. The cost of electricity is higher, the price is higher, the cost of gas is lower and the price is cheaper. A cubic meter of natural gas (price in 2.5 yuan) = 10 1 kwh (price in 5.3 yuan). It can be seen that natural gas is the most economical, and electricity is more than twice. For the same job, if the electricity bill is 5.3 yuan, the natural gas only needs 2.5 yuan.
