Default Conserving Energy with Electric Oven?

Here's a question that I googled for but couldn't find any definitive
answer:

I need to roast a 15.5 lb turkey Saturday night. It's already
marinating.

Which of the following methods is more energy efficient?

Higher heat, shorter amount of time?
or the standard 15 min per pound at 350 degrees?

I have an electric oven.

Thanks.

Sorry, but if I had to worry about the insignificant difference, I wouldn't
be roasting a turkey.

Default Conserving Energy with Electric Oven?

Catmandy,

A lot of it depends on how new your oven is. Newer ovens are
typically more energy efficient than the older ones. They are so
because of a mixture of better electronics to maintain the desired
temperature and better insulating technologies.
I often wonder the same thing when I use the self-cleaning feature of
our oven. I know that it would be cheaper for me to clean it manually,
it most likely uses $0.60+ for a 2 hour self-cleaning.

Sometimes you have to make a choice about what is more important. My
wife and I do not dine out much, we prefer to dine at home for several
reasons (intimacy, noise, price). We mostly make this choice because we
have a much more intimate dining experience at home.

Now, back to the turkey... You will probably see a slightly lesser
energy usage by cooking it at a lower temperature over a longer period
of time. Your oven will radiate less heat because the lower temperature
is closer to the ambient temperature of your kitchen. However, the
choice comes in when thinking about the desired taste. Personally, when
we do turkey, we do the high-low method. We start it high to slighly
sear it, then we lower it to do the internal cooking.

A good compromise would be to turn off some lights and other
appliances while cooking. Instead of watching TV while cooking it, turn
on the AM radio and catch a cooking show on Saturday (most major
markets carry at least one).

Hope that helps,

Charles

Who said I was "worried" about the difference? Wondering, yes.
Worrying, no.
I merely asked a polite, direct and on-topic question. Who ****ed in
your cornflakes this morning?

Didn't you ever just "wonder" about something? Oh wait, that would
require thinking on your part. Never mind.

Kinda answers the question. A heckuva lot more helpful than "Wayne" and
"Greg" (RFC's very own fruit of the month club).
Not really worrying about it, not really going to change the method of
cooking....just curious is all.

Seems to me it would be a wash, and if there were a difference, it
wouldn't be noticeable anyway.

You pretty much confirmed what I suspected.
Thank you for your polite answer to my polite question.

Oh yeah, let's play the martyr and victim card, shall we, SHERYL...???

Next you'll be recounting all the people here who "betrayed" you, your EV -
UL stepmother serving you that Thanksgiving gravy in a rubbermaid pitcher,
the boyfriend who beat your cat, your mother not being able to get that
Molly Picon autograph, etc., etc., etc., etc....

Considering some of the stuff you've directed towards Carole in the past,
I'd say she is *mighty* nice in taking the high road by "welcoming" you
back...

Actually, your presence here is about as "welcome" as a that of a cockroach
running across a wedding cake...but stick around so we can at least get some
cheap "entertainment" value from your presence.

In any case we are absolutely tickled pink that you deigned to stop by :-)

A few assumptions and some back-of-envelope calculations may be
enlightening. Assume a 10 kW oven element, that cycles 'on' for about
one-fourth the time, and electricity at 10 cents per kWh.

It sounds like the turkey must cook for about 15 x 15 or 225 minutes.
Call it 240 minutes, four hours. The oven draws current for about 1/4
this time or one hour. 10 kW times one hour is 10 kWh. At 10 cents
per kWh, the cost of roasting the turkey is roughly one dollar. (I've
overestimated; it's probably less.)

If the oven is set higher it will use somewhat more electricity for a
somewhat shorter time. It is likely to be slightly more electricity
but now we know the magnitude of the savings---probably well under a
buck.

That's not to say that saving energy is futile; it's not. But when I'm
roasting the Thanksgiving turkey and the holiday depends heavily on it
being a good meal, I worry about: rinsing the salt from the turkey,
getting the gravy right, etc. I don't worry about a dime's worth of
electricity wasted.

Who stuffed a rag up your ass? Your use of "conserving energy" implies to
me that it was a concern. Do whatever the hell you want.

Considering pure physics the higher heat for a shorter time will
consume more energy... it requires more energy to maintain an oven (gas
or electric) at higher temperatures the same as it does to run an
automobile at higher speeds (the higher temperature and the higher
speeds are *increasingly* less energy efficient - every rocket
scientist knows this). In both cases you'll get there faster but it
will cost more energy.

But then there's also the safety/result factor... going more slowly
will get you there with less risk along the way.... there's little
point in racing through the process at the higher temperature/speed
while risking the turkey burning on the outside while being not quite
cooked on the inside (kinda difficult to correct after the fact - well,
there's always turkey soup)... the same as speeding down the road
increases the risk of not getting there alive.

I'd opt for the cooking methods recommended on the turkey package, it's
safe to assume the turkey provider's *collective* test kitchens have
had a lot more concentrated experience than the *collective* results of
a lot of folks who roast like only 1 turkey each per year.

Anyway, regardless which method you choose for cooking your turkey the
difference in energy consumed is miniscule (opening the oven door a
couple extra times negates the savings). Someone truly intent on
saving energy would use that hot oven to roast *two* turkeys (cuts
energy consumed per bird by half)... maybe you have a neighbor who
would like to do a cooperative thingie; your turkey and their fresh
ham... and you can even share the bounty... and to maximize the
experience eat at the same table. Good luck, Sheryl... enjoy your
dinner.

Physics you say? How exactly does heating an enclosed space for a
shorter period of time require so much more energy than heating
it to a lower degree for a longer period? Rockets and cars are
dealing with acceleration, gravity and friction. The oven is
just heating up the air in the enclosed cabinet, much if which is
absorbed by the food being cooked.

Since you referred to the subject of physics, please enlighten us
about how cooking two birds in an oven cuts the amount of energy
used per bird by half? The meat is cooked by transferring
electrical energy in the element, or gas in the burners, to heat
energy. That energy is absorbed by air molecules which in turn
transfer it to the poultry carcass. It takes a prescribed amount
of heat to raise the temperature of the roast to a certain degree
of heat. Doubling the amount of flesh to be cooked basically
doubles the amount of heat energy required to cook it. Of course,
ovens are not totally energy efficient. They lose heat through
the sides, through the vent and through the frequently opened
doors.

If you put a pot of water on a burner it will take a certain
amount of heat energy to bring it a set temperature. If we accept
what you say about two birds in the oven requiring only half as
much energy per bird, then we can expect that it will take the
same amount of energy to bring twice as much water to the same
temperature. It doesn't. It takes roughly twice as much.

I realize that two small birds will cook faster than one big one,
and that two equal sized roasts will cook in an oven in the same
time that one of them would at the same temperature, but it still
requires more energy from the oven.

Unfortunately she gives the standard temperature but not the higher
temperature... I doubt she means like 10ºF more... but all things
being equal whatever inefficiences are present will be magnified at an
ever accelerating rate as temperature is increased. And cooking by
convection (heating air) is one of the least efficient uses of energy.

Btw, it's more efficient to cook two 13 lb turkeys... most folks waste
a lot of energy by using a full size oven to cook a small amount of
food... will probably consume less energy to cook two turkeys than the
one... costs more energy to maintain a heated empty oven than one that
is filled to the ideally engineered level.... for exactly the same
reason it costs more energy to maintain temperature in an empty
freezer... folks who run a freezer filled with bread are nuts, for it's
volume bread is mostly air, has little mass, the freezer may as well be
empty... it costs more energy to freeze bread than bread is worth, and
stuffing empty space with bread just impedes air circulation. Very few
folks actually save money with their freezers, the vast majority spend
more in wasted energy than any savings in buying the food... every two
pound loaf of frozen bread negates the savings of each three pounds of
meat bought on sale.

Most stove/refrigerator-freezer appliance manuals explain about
deriving maximun energy savings by optimizing space usage. No one
knows this space/energy relationship more intimately that those who
cook shipboard... where all energy is produced on board and space is
limited/finite.

You're right. I don't work. I haven't worked for 2 1/2 years and
I have not been looking. But I am so happy for you that you tore
yourself away from the Jerry Springer show to share you lack of

For someone who worries about my job status you spend a lot of
time stalking me here just to make idiotic comments.

Not residential ovens... have never seen one where it's even possible.
Idiot, obviously you've never used an oven... other than that toys r us
kind that heats with a light bulb.

<LOL> Shecky offers answer # 31 from the "What shall I Post
when I'm Wrong" album of such frequent use.

Energy is absorbed by the cooking birds in the course of
raising their temperatures. The oven cycles more often to
compensate. More energy used.

Oh oh. Now Dr. Shelton is going to have to explain thermodynamics
to two of us. LOL

Oh no, no. Please indulge me. I am really curious about how two
birds roasting in an oven will require only half as much energy
each to cook.

It takes a certain number of calories of heat, or BTUs if you
wish, in order to raise the temperature of a given quantity of
roasting flesh. I am really curious about how you can cook two
birds with the same amount of heat that it took to cook just one.
