- shortyjacobs, on 11/24/2008, -0/+11I love it. She's telling us how to save money by spending 3 cents using a microwave oven instead of 7 cents in a conventional oven.
But she likes to freeze and defrost food every day. If you just take the latent heat of fusion for 1 kg of meat, (2.2 lbs, or a roast for a family of four), it takes 333000 joules to freeze it....a kilowatt hour is 360000 joules. So at $0.10 per kWh, it costs her 9.25 cents just to freeze the roast. Then that heat has to be dumped from the house, (in summer), or the defrosting roast has to be reheated (in winter), using even more energy. - inactive, on 11/23/2008, -0/+10Asparagus FTW!
- callmejack07, on 11/25/2008, -1/+10As a Culinary Student, this article is way off base when he/she says "I've never noticed a difference in my food when preheating the oven" and turning off the heat won't matter.
All this article is good for is the stats on electricity. - ElGranMonkador, on 11/25/2008, -0/+8not preheating an oven? is she stupid?
come on.. especially when it comes to roasts, putting a cut of meat into a cold oven will sap all the juice out of the flesh and you'll end up with a bone dry roast, which to me is the biggest waste of energy.
so its true, we all cook better when we're cookin with gas - DonJuanAussi, on 11/25/2008, -0/+5The readers comments are pretty correct. For baking, pre heating the oven is critical. in fact, for sponge cakes and similar light cakes, time is so critical that you need to pre prepare and measure all the ingredients before starting the mix.
The best way to save on power, is to bake biscuits (cookies for Americans) while roasting/baking if you have the room in the oven. - Dinsdale77, on 11/25/2008, -1/+5Because people are always putting asparagus in the oven.
- no1digger, on 11/25/2008, -0/+4Are you kidding me with this article?
- DealCracker, on 11/25/2008, -0/+4 I worked in the cooking lab of a commercial oven manufacture and designed numerous food cooking tests. Maybe skipping the preheat cycle doesn't effect the author's Swanson frozen dinners, but real bakers know that preheating is far from a waste.
Also, as others have pointed out, the author seems to be hopelessly lost when it comes understanding energy, latent heat, specific heat etc. While well intentioned, this article demonstrates how even a seemly simple energy problem can be complex. Imagine what it would be like to try to understand the thermal dynamics of the whole earth. Nobody has even come close to understanding that regardless of what Algore says. - Ne007, on 11/25/2008, -0/+4Is this what things have come to?
- Rockkybox, on 11/25/2008, -0/+4??
- Barackalypse, on 11/25/2008, -0/+3I make my own organic charcoal to cook with, I'm way greener than any of these tips. =)
- austang, on 11/25/2008, -0/+3Screw it, I went to Whole Foods and a turkey there costs $70, energy is the least of my worries.
- Jektal, on 11/25/2008, -0/+3Maybe he just got a 184 lb turkey?
- austang, on 11/25/2008, -0/+3true true,
it's just if I'm getting turkey I want real turkey, otherwise I WOULD just eat the usual bacon stuffed with more bacon. - TheMachine1, on 11/25/2008, -0/+3I have the original Necronomicon on my bottom oven rack. The evil from it bakes my bread.
- Jektal, on 11/25/2008, -0/+3Sure, but how much Blood of the Innocent do you go through? That adds up.
- noph44, on 11/25/2008, -1/+3Honestly, whomever created this article is a little overly anal retentive. It's great to save energy where you can and of course if half of the households in the U.S. utilized these and saved even 10 cents a month on energy that would seem like a lot, BUT IT'S NOT! When it comes to "being green" you really have to pick and choose your battles better than this. I'm sure that even the person who wrote this article has another aspect of their life that they could save a lot more in energy on than the tips they outlined in the article.
Ridiculous, lay off the the granola! - sdellboy, on 11/25/2008, -0/+2Sticking ones head in it?
- MadCatter, on 11/25/2008, -0/+2Shopped.
- Barackalypse, on 11/25/2008, -1/+3There's your mistake, my grocery store has them for 38 cents a pound, although why you'd want to waste a meal eating turkey instead of bacon wrapped cow is beyond me.
- inactive, on 11/25/2008, -0/+2Freezing food? Eww...
- FindTheGreen, on 11/25/2008, -0/+2Great, I can save 4 cents by using the microwave, and rubberizing my food at the same time. How about using a solar oven, now there's a truly novel idea to save money and the planet
- monarch00, on 11/25/2008, -0/+2Why is this on the front page?
- Jawua, on 11/25/2008, -0/+1Energy and Oven, in energy we find strenght, in oven we find over hit.
- mrrealtime, on 11/26/2008, -0/+1cheapest and easy ways to save energy:
buy local..kijiji is great for getting locally available stuff
make sure you have good weatherstripping around your doors and windows seal well
improve your insulation. Insulation is very cheap and easy to install.
telecommute whenever you can
recycle clothes, furniture, books and anything that doesnt gross you out.
if everyone just did those things our global energy production needs would likely be halved. - gorkaboo, on 11/25/2008, -0/+1I've seen a friend set his oven on fire because he did not preheat it before cooking his frozen pizza. Melted straight through. The humanity...
- chrismar08, on 01/14/2009, -0/+1good stuff....

http://justmileycyrus.com - kichler, on 01/08/2009, -0/+1Well I perfectly understand the saving energy part, but what about the food quality part? Shouldn't we consider this too? All those saved money from using the oven could be spent for our health and we can realize in the end that we didn't do no savings after all... That's just an hypothesis.
