Does anyone know of any good web resources..

| Does anyone know of any good web resources for guidance on saving energy in
industrial applications ?.
In our case, plastics extrusion.

What ever happened to asking how to make *better* extrusions? Or making
*more* extrusions, more quickly?
I am getting so heartily sick of all this carbon crappery. When young,
the dream was of "JetsonWorld" - door to door air (and space)
transportation. Whole wall TV displays. Trips to the moon for lunch.
Now, even thinking of going to the shops in your car is a crime. As for
a flight across the Atlantic. Hell, you deserve horse-whipping..
If half this green crap actually worked better, then fine. Save the
energy, if it also gives a better product. But no, we have
"econo-flushes" .. that don't flush the loo adequately. Hoovers which
suck - unfortunately the wrong sort of suck.
I do not want to end up with a World in which no one travels. No one
builds a 49 bedroom house just because they want one. No one runs a
deep, hot tub and has a good soak in it for an hour.
What I want is all this green crappery investment going into generating
electricity so cheap and plentiful that it isn't even billed for by the
kWHr. Micro fusion plants that will fit in my personal helicopter. Every
wall a full TV screen, so I can move to Pluto - so that my mind and soul
can get there, even if my body can't.
And yes, questions about how to make the best extrusions.. oh, and if it
also can do so using less power, then great..

In my case the general manager mandated that automatic shutoff sensors be
installed for the high efficiency fluorescent light fixtures with electronic
ballasts that were already in place. Now we spent more on replacing lamps
and ballasts then if we left the lights on 7/24.
My recommendation: go to your own engineering department and ask for a
common sense approach to reducing energy costs. Tell then up front what the
approximate budget would be for implementing such changes.
One possibility is that sometimes electric utilities give better rates to
industrial users who correct the power factor to their loads.
You can also try the Detroit strategy of laying off one shift or closing the
plant down (sorry for the sarcasm).

And then they'll charge you with cruelty to animals. ;-)

I read about a company that assists other companies in 'going green', such
as designing gadgets for reclaiming waste heat, using skylights and other
sun-powered devices, and several other energy saving/waste reducing
practices that helped large companies save money.
I believe I read the article in Popular Science or Popular Mechanics.

Now, now. "Saving energy" also saves money (or I wouldn't be so
cold in my house). Saving energy is a legitimate concern for
engineers.

Sure, and I wish they'd heat the Grand Tetons in the winter and air
condition the Painted Desert in summer too. ;-)

Convince Al Bore of that, please!

I bet you really love ROHS, too.

....no one looks like a prune...

We're getting there. Have you noticed the prices of plasma TVs over
the past decade? Hmm, not very "green" though. My 42" uses consumes
over 200kWh/mo (but we heat with electricity, so...).

Ah, shucks. I was having fun. ;-)

Sue and many others here are very knowledgeable and very helpful. A problem
that frequently arises is that the questions posed are so woefully lacking
in information that much "reading between the lines" is needed to respond.
In this case the question is so generalized that only a general response is
possible: A. ask your engineers. B. hire an outside consultant. C. ask your
competitors how they do it.
Personally, my hero was Henry Orbit the repairman. Considering that George
slept most of the day Mr. Spacely wasn't overly concerned about efficiency.

I guess the main energy drains will be the heaters and extruder motor -
there's not so much scope to change the working parameters of these without
affecting the product.... so I expect you'll need to look at peripheral
devices to see where you can save a few pennies...
