Quote from @Bruce Woodruff:
Oh, and no one has mentioned that in order to run an electric stove, you must use fossil fuels. The green people always seem to forget this. The percentage varies by where you live, but it is somewhere between 60 and 90%.
A gas stove is about 40% efficient, an electric stove is about 75% efficient. If you are in California, 50% of your electricity come from gas, the rest is mostly nukes, hydro or renewable (coal is .2%). Factor in distribution losses and you are still using less gas to run an electric stove than a gas one.
But also keep in mind that the business case for electrified cooking is the weakest of all the appliances, the strongest case is for water and space heating where heat pumps use 1/3 the energy to do the same thing. Most people living in California would use less gas for heating if they had a heat pump that was powered by a gas turbine somewhere. They are that efficient.
