I used a gas oven for my above mentioned cooking - worked just fine. I suppose that there must be some sort of circulation in a gas oven to support combustion, but I also assume that the oven design supports that need without losing efficiency.
If we are talking efficiency, in much of the world electric ranges are far less efficient overall. To make electricity, the power company first boils water to make steam to run the generator. To convert the electricity thus generated back into heat is extremely inefficient. Much more effective to just use gas directly to make the heat one time.
