Our electric bills are horrendous. Our house is all electric and we just use a lot of electricity — lots of hot water, we all take two showers a day; the dishwasher runs at least once a day, often twice a day and sometimes three times a day; I have two ovens and many times, both of them are going. One of the not-resolutions-but-a-plan-I-had was to use the crockpot more this year and see if using the stove less would help the electric bill.
But, I love my pressure cookers so much more than I love my crockpots! Even though I have several, this little 3.5 liter Kuhn Rikon is my favorite. It’s perfect for a small roast, just enough dried beans for a couple of meals and cooking a whole small chicken. I also have the 5 liter Kuhn Rikon. (Don’t ask me why the 5 liter costs less than the 3.5 liter at Amazon!) The 3.5 liter is about a 3.7 quart size and the 5 liter is about 5.25 quarts.
I also have a 6 quart Presto cooker. I’ll do a separate post about the pros and cons of each.
For a while, I’ve been wondering if it takes more electricity to cook in the crockpot or in the pressure cooker. Just off the top of your head, what would you guess?
This post is great and answered my questions. It discusses the different methods of cooking leg of lamb. They figured the cost of cooking it in the crockpot was 11.2 cents and the cost of cooking it in the pressure cooker was 4.5 cents. Cooking it in the oven cost 23 cents. Even though the cost was all I was concerned with in this article, the lamb cooked in the pressure cooker won the taste test too.
The cost savings for the pressure cooker vs. the crockpot isn’t going to change my mind about what method I’ll use to cook. If I’m reading the article correctly, it saves about 7 cents to cook in the pressure cooker. If I save 7 cents per day, then I’m saving a grand total of $2.17 per month. I don’t think that’s going to make a noticeable difference in my electric bill.
These figures were based on electricity costing .10/kw hour. I called Kansas City Power & Light this morning to see what we’re paying and during the summer, we pay a flat .10/kw hour. During the winter, we pay .10 for the first 600 kw hours, then pay .05 for the next 1,000 kw hours and then it drops to .04/kw hour. So, during the winter, my costs would be half of the figures referenced above.
The leg of lamb was cooked 4 hours and when I cook most anything in the crockpot, I cook it 6 or 8 hours so that would mean that my cost would be in the 16.5 – 22 cents range. That’s still not enough to make me change my mind if I were planning to use the crockpot.
The savings of the pressure cooker vs. the oven is 18.5 cents or $5.73 for the whole month. But, during the summer, the oven heats up the house and that is a consideration.
I’m a bit surprised that the savings isn’t more. Another and probably bigger consideration for most of us is the convenience or preference in cooking. If you’re going to be gone most of the day and want dinner ready to serve when you get home, obviously the pressure cooker isn’t going to be your first choice. I’ve always had better luck and seem to get better tasting food with the pressure cooker. I will continue to use the crockpot some but I won’t feel like I have to do it in order to try to save electricity. The pressure cooker will still be my preferred method for cooking.
I’ll do some more posts on pressure cooking over the next few days so if you’re interested . . stay tuned.
