the cost of pipeline natural gas is the cheapest, followed by canned gas, and the highest is electricity.

natural gas in equipment and pipelines is very expensive, followed by electrical appliances, followed by canned gas equipment.

in the long run, pipeline natural gas is highly recommended, which is safe and convenient once and for all. That's what I do. I work in more than 111 restaurants in 4-tier cities for 1 months, and natural gas pipeline is really the best solution.
