Just a quick one... the 5% cooking cost, is that an average household?
BTW what is the number of people in an average household?
We cook 7 nights a week is this average?
Sorry, trying to work out some basics, like is our household above or below average

I once did some calculations on energy use of cooking appliances for one hour worth of use.
Rice cooker / Slow cooker (350W): 0.6 - 1.26 MJ
Microwave oven (100-1000W): 0.7 - 3.6 MJ
Convection oven (700-1400W): 2.5~5 MJ
Stove (simmer to wok burner): 1~15 MJ
I also tried working out our household cooking use where we rarely go out. Gas cooktop usage was about 4MJ/day (based on gas use in summer versus winter). Because we were already using gas heating, this only added $27/year to our bill.
I couldn't imagine a induction cooker making a big dent on that one.
4MJ/day is equivalent to about 15min stir-fry, 4 hours simmering, 1 hour convection or microwave oven on high or 4 hours slow cooking.
It was impossible to calculate electrical consumption for cooking. But it was to operate the following appliances - oven, microwave, slow cooker or water jug. We often used a micro-convection oven rather than the big oven for grilling or minor baking. We are not big bakers and use the big oven less than 4 times a month.
Slow cookers and rice cookers conserve heat well and because large amounts can be done you can make several meals from one cooking session. Steaming is an efficient means of transferring heat into food whereas convection isn't.
