The wife thinks she's saving money by buying two pounds of corned beef brisket at $2.69/pound. However, it takes 2 hours to bake at 350F. Is there a way to convert 350F times 2 hours to kilowatts? We pay a sliding scale for electricity from 12 cents per KWH for the first week of the month (or so), to 45 cents per KWH for the second half of the month, so I can average the electricity to cost something like 25 to 30 cents per KWH. But, how many watts does it take to bake? I realize once I figure out the watts, the rest is easy. But how do I figure out the watts in an hour at 350F?

Google is your friend.... Also, I think what you're saying is that you have tiered electricity rates, so that beyond a certain point, you pay more. If so, I would not use the average rate, because if you add that additional cooking time, it's at the incremental, ie higher, cost. Using your $.45 rate and the calculator, gives a cost of $.70 Also, if you're using the oven now, during the winter, you're also getting free heat for the house from it. That reduces the true cost. And boy it must suck to pay those rates. Here in NJ I'm paying about $.17 and it's one of the highest rates in the USA.

How much does it cost to heat "corned beef brisket" for 2 hours at 350 degrees?

It also shows how terribly inefficient cooking can be

Lets say we cook that corned beef to 160F, corned beef has to have a lower thermal capacity than water which is 1 BTU/lb * F

so roughly we need to raise the temperature of the corned beef 100 F, for 2 lbs this is 200 BTU or roughly 60W, less than 2 cents of energy at $0.34/kWHr. An insulated crock pot would waste less energy.
