Is it cheaper to boil a kettle on gas or electric？
Electricity is the most thermally efficient, so it saves the most money. Electric heating water, hot spot in the water, heat energy utilization efficiency is very high.
So now families are widely used electric kettle, one is clean, two is to save money.
The thermal efficiency of boiling water with natural gas is very low, and a large amount of heat is lost quickly.
Natural gas is a gaseous fossil fuel composed mainly of methane. It is mainly found in oil and gas fields, and to a lesser extent in coal seams. Natural gas, like crude oil, is buried in closed geological formations underground, some in the same strata as crude oil, some in a separate reservoir. For natural gas stored in the same horizon as the crude oil, it will be extracted along with the crude oil.
