    Question Would you upgrade (or downgrade) hardware just to save energy?

    I just "downgraded" from a 24 inch LCD monitor to a 23 inch LED LCD monitor to save energy. I just wonder if anyone else has ever done that? I did it to save money as I am always on the third tier on my electric bill and just added a refrigerator in here.

    Would to give up CPU power and graphics resolutions to save energy? Would you replace something before it was a necessity to save energy?

    I am currently using a 19 inch LCD. I had previously been using a 17 inch CRT. I presume that the larger LCD display uses less energy than the older CRT display.

    I also turn the brightness down on my LCD display. I presume that saves some energy, but I do it mainly because I prefer a screen that is at less than max brightness.

    Comparing to my previous computer, the current one has more CPU power, higher graphic resolution, but uses less energy. The choices are not always what might seem obvious.

    If you are moving to a new spec usually the energy consumption goes down. I went to a 6 core on one of my Ham radio computers and it's uses way less energy most of the time than the quad cores I run Linux on. They absolutely uses less energy that the dual core I had before.

    LCD uses less than a CRT. I am pretty sure with a LCD that is consumes the same energy no matter what the brightness or contrast settings unless the screen is blanked/off.

    I think it is the other way round, in CPUS. Voltage goes down, but
    frequency goes up. The power rating of my current CPU is a lot more than my
    older P-IV. The fan and cooler is impressive in comparison. The wattage of
    the power supply is triple at least. On the other hand, it uses less when
    idling.

    Mine hardly breaks 800mhz. Energy consumption is way down on newer CPUs over the long term.

    I believe switching power supplies such as computers use don't draw more current than they currently need. In other words they draw less current with they are at 800 mhz over when they are at 3000 mhz or above and they may only draw that current on one core as opposed to all 2 or 4 or 6 sometimes so they consume less energy over all.

    Nope.

    From CRT to a bigger LCD, yes. And uses way less energy.

    I need bigger, my eyesight is no longer young.


    When I buy new hardware I take in consideration how much energy it uses,
    and I do seek the lowest figures; but I will not change working hardware
    just to save energy, because the purchasing price doesn't usually
    compensate the energy savings.

    As a rule.

    But I have changed most of the bulbs in my house for low power, compact
    fluorescents - the power savings are considerable and the prices are much
    cheaper than they were 5 years ago.

    Although they don't last as much as they claim, and they contain mercury,
    which is a hazard. Anyway, bulbs are no longer made here in Europe, AFAIK,
    so must people are forced to do the same, like it or not.

    I would say the major source of energy waste is leaving the machine running when not in use.

    300 watts x 24 hours = 7.2 k kilowatt hours which here in PA is about 72 cents per day, which is about $21.60 per month if you leave it run all the time and it is running at full bore.

    I have stuff on one machine that I leave running 24/7 so it consumes lots of energy. I am trying to arrange it so all the things I need and activities I need to run 24/7 are on that one machine. Plus I run two monitors but both are LED now and they get turned off when I am going to be away for more than 15 minutes.

    While the load is low, yes. If it is high, no. :-)

    If i could afford it, certainly.
    Right now, i prefer to just turn things off to save energy.

    That reminds me. I read often that the Linux Kernel has problems (or not) for notebooks. Does that affect also desktops?
