Sure. Here's one
Jennifer Mitchell-Jackson, while a graduate student at Lawrence Berkeley National Laboratory, measured the energy use of an average microwave oven, an electric stovetop, and a gas stovetop to heat up a mug of water. Turns out that an electric stove uses 25% less electricity than an average microwave oven to heat a mug of water. A gas stove is less efficient and uses more energy than a microwave oven, but depending on the cost of gas, it might cost less to heat a mug of coffee with gas compared to the microwave.
And a gas oven is WAY less efficient than an electric oven since there must be a flow of fresh air through the oven to feed the flame.
Thanks, so we have conflicting sources. Now we just need to find some that include all the numbers.

If all three are possible, great. Of course, when I was doing off-grid stuff, I leaned strongly towards renewables instead of fossil fuels, as did my customers, but even there the sequence was the same: First don't use it; 2nd use what you do as efficiently as possible; and finally generate what remains with renewables (whenever possible). Having done the whole solar oven bit in the past, and sold them too, they simply don't fit my lifestyle or circumstances now. They are the exact opposite of a microwave when it comes to convenience, but they are unquestionably the lowest environmental impact as well as the cheapest way to cook.
Gasoline-fueled 4WD vehicle. Inefficient gas cooktop and oven. Gas water heater. We get the picture.
Why yes, that's part of the picture, Reg, but hardly all of it. Bicycle for commuting and local errands beyond walking distance (most routine errands are within .5 mile). Electrified mass transit plus bike for most regional trips. Car sits in driveway for weeks at a time, used less than 3k miles a year (well under 1k this year, owing to constant winter storms and then summer fires that kept me out of the mountains). No flying except for emergencies or bucket list items, until large % of it is renewably fueled (haven't flown anywhere in more than 15 years). Rarely cook (never use the oven, eat out a lot). 120V service only. Live in a 325 sq. ft., well-insulated studio well-sited for passive solar. Have all on/off loads on switched power strips. Don't use outside lights, and only have one on at a time internally (task rather than area lighting whenever possible, and all are CFL at the moment, to be replaced with LEDs as they fail). Use a line for drying clothes, etc. etc.
We all make choices, Reg. How is it you use a car for your local driving, live in a large, detached house and don't cook using a solar oven or use a manually operated washing machine (I used to sell both for my off-grid customers)? Do you fly, or take the train? You have kids. Eat meat (which kinds)? And so on. We all decide how much we're willing to put up with for the sake of saving energy, money or whatever. I'm comfortable with my decisions, I assume you're comfortable with yours, and neither of us is willing to live naked in a hole in the ground or a cave (I have lived in a snow cave for a few days at a time, but that doesn't count).
