Losses from the plant to your home average 5% [0] If the electricity is generated in a combined cycle gas plant you get about 64% efficiency [1], so the actual efficiency is about 60,8% if you take the losses into account. A regular electrical stove is 82% efficient (this plummets to 40 if the pot doesn't cover the heating area) and an induction stove 76%. [3] A gas stove has about 40% efficiency (fig 8) [2]. In conclusion, assuming your cooking pot covers the heating area, electrical heating has 44% efficiency and is therefore 10% better than gas. This is not all that needs to be taken into account though, a sibling comment already mentioned this but we also need to take additional issues into account such as pollution due to incomplete combustion. This is a big issue inside densely populated cities, so a reduction is usually very welcome.
