    As Pondini points out, there is often a hidden cost to doing something that seems on the surface to be energy efficient. For example, contrary to popular belief, idling your car for a short time is more environmentally responsible than turning it off and back on again, since the catalytic converter only works when very hot. Turning off the car lets it cool and means that, when you start it up again, your car is spewing some toxic gases until the heat from the exhaust can bring the catalytic converter back to the necessary temperature. (Don't ask me what the break-even point is, I have no idea.)

    Sorry, Thomas, but where I come from, it is actually illegal (and you will be fined!) to keep your car engine running for more than 60 seconds (such as railroad crossings, road construction stops, etc) - the 60 seconds was in effect when I left the country in 1993; I'd have to find out if that has been changed.

    Edit: Should have put a smiley face at the end of my post to make sure everyone understands I'm not taking this all that seriously. But what I said is true...

    Yes, sad to say that lawmakers often create laws that don't make sense and are not particularly grounded in fact. Fortunately, the laws of physics fall soundly outside their jurisdiction.

    Actually, in most of Europe (and Germany in particular), successful efforts at conservation have mostly far exceeded any other countries' efforts. And the (German) cars are - by necessity (partially due to the extremely high cost of gasoline) - manufactured with those concerns in mind. Environmental issues have been considered very serious issues there ever since I was a child - packaging has always been minimal (very little waste) and recycling has been done for many years as well.

    I think this conversation is running a bit astray from the point, but conservationists are often no more educated on the science of an issue than the lawmakers are. Not to say that recycling isn't good and cars shouldn't be efficient and that everyone can't do better, but at the same time few environmental issues are as clear-cut as they seem. Hydrogen cars and electric cars are "good for the environment", but where does the power that ultimately is required for both come from? Mostly coal and nuclear. eBooks are environmentally-friendly because they don't kill trees, right?... except the readers have toxic batteries and run off that same mostly coal and nuclear power, while most books are made from at least some recycled materials and/or fast-growing softwoods that are farmed, and are completely renewable resources. It's important to look at all facets, and to bring this back home, it is probably more energy efficient to put your machine to sleep than it is to start it up every morning and shut it down every night (assuming you're using it every day).

    I agree with that and I'm glad we were able to have a friendly discussion about it.....

    And, lest I forget, thanks for jumping into that other thread; I thought - obviously mistakenly - that the OP was interested in learning something. Your efforts were exceptional!

    Yup... too bad those sorts of discussions aren't encouraged here, I kind of enjoy talking about that sort of thing... I'm sure you couldn't tell!

    Thanks! That was an amusing thread.

    Barbara, I'm not getting started again on sleep vs. shutdown redux (I've had quite enough of that one) but there was an extremely interesting article in The New Yorker a few weeks back (12/20/10) on the idea that as we become more efficient in using energy, energy consumption, quite counter-intuitively, may in some situations actually rise, thereby completely offsetting any gains -- even, possibly, end up making things worse. This phenomenon is called The Jevons Paradox. Unfortunately, no longer up on the site, but here is a link to the abstract of the article.

    The Efficiency Dilemma
    If our machines use less energy, will we just use them more?


    In other words, to save the planet everyone should drive a Hummer!

    There were a couple of letters in a later issue (1/17), claiming fallacies in the original article.

    They claim most of the increases were actually related to population and GDP growth, and use +per capita+ was in fact reduced.

    One (a professor of economics at Tufts) says US energy consumption rose 31% between 1975 and 2009, while the U.S. population grew 42%, and real income per capita rose 87%.

    I certainly agree with that and thanks for the link. I think the debate will go on for decades....

    Back on topic - I wonder if the OP has left the building?

    Yes, it is certainly true that exponential population growth, with that increased population worldwide having ever accelerating access to limited natural resources, is unsustainable. Whether Jevons was right or not, we won't solve that one alone with energy efficiency. (Viz. China, India etc. Case in point: what's been happening to the price of gas this winter when reduced seasonal driving in North America and Europe should have been bringing it down; instead it's been going up.)

    Hi there,

     

    I live in Australia, and usually power my Mac off at night. I have read that Mac does its own internal 'clean-ups' 'early am local time'. Whose local time?! Is that the time zone for the US? How can I find out when that sort of maintenance goes on for the East coast of Australia? That way I can leave it on sleep mode for that time, say once a week.

    "Local time" means the time on your computer.  Note, though, that those scripts are quite unimportant these days.  Those clean-up scripts are a bit of a leftover from the Mac's Unix server roots.

     

    BTW, rather than resurrect a topic that hasn't been posted on in 8 months, it would be best to start your own topic in the future.

    Thanks for that. OK, get the point about the topic. I just thought if I started a new topic people would point me to this one! Anyway, thanks.

    Beware! MacKeeper is such a SCAM. You can do most anything listed with the built in utilities already on your Mac. Invest in products like Alsoft® Disk Warrior, Onyx and "What Size Is It" utilities. The free app "Apple Jack" is very effective also. Don't waste your money.

    MacKeeper shamelessly uses pop-up adds to lure unsuspecting Mac newbies to buy its products. Don't do it!
