    No Bro, the setting is almost 25 Deg C. Not quite at 25 yet, but almost there. Those occupants of the rooms at the side of the building complained when it hit 25.

    I was reading the newspaper last weekend. It was mentioned that there are some cities in the world that are planning to be carbon neutral. I am wondering, how can we be carbon neutral? There are bound to be carbon emissions. Do they mean that they have 'green lungs' area to absorb the carbon emitted?

    Carbon neutral means they got some other means to offset their emissions.

    For example, let's say City A emits 10,000 tonnes of carbon, so they plant more trees elsewhere that can absorb 10,000 tonnes.

    Its may not be the same carbon that City A emits, but the net effect is neutralised.

    neat idea...

    cant they become carbon negative, and offset some other cities emission..

    Oh yes, some cities do. That's why they have a carbon trading market, where they can sell it to countries that emit above their quota.

    human also produce carbon as in CO2 wat... just not as much as direct burning.

    instead, y not use the excess carbon to make into diamonds, more economical rite (wishful thinking)

    Wow! There is such a thing as carbon trading? I didn't know that. Thanks for sharing, swerve.

    Not that way - they have switched to 'bio-fuel'. Even traditionally they used a lot of ethanol mixed in anyway - now they have just switched completely.

    Now to weather it was better to leave the farming land they used virgin forest or use it for growing food instead of liquid fuel is a whole other argument.

    As the international carbon trading systems get going, it's going to be relatively easy to be 'carbon neutral' but I don't think it will result in an optimal system by a long shot, in particular it already seems to be pushing up food prices as farmers find they can make better money out of fuel crops instead of food crops.

    Really we have to restructure our energy use patterns, particularly in transport, where the entire sector is addicted to a cheap high density portable liquid power source - and with western economy's still quoting car sales figures as part of their economic heath, it ain't going to be easy.

    Can you see transport being exclusively run by electric railways and sailing ships any time soon ? We have spent the last 100 years or so building an entire world economy around cheap meshed point to point transport fuelled by a high energy density liquid hydrocarbon. Undoing this is going to be hard and painful.

    Spent some time today morning activating back my connections cos last night someone pulled the plug off the server and switches...

    So i found out who the one who pulled it... and the reason? Media say, even if we off the system, its still using energy... so this person go switch off the mains of the server and switches since everyone go home already...
    This person needs to be given a serious talking to. Unless it was the boss, who hopefully you can make understand that you can't just go turning off the infrastructure like that.

    It may be worth while investigating the power management in your server(s) at least and configure them to go into lower power modes when idle - like slowing the CPU down and stopping the hard disks when idle. Nearly all servers I currently run have Intel Speedstep or AMD PowerNow, and the CPU's change speed depending on demand. Unfortunately I don't have any RAID controllers that can power down the drives when they go idle.
    Lowering the clock speed is only a small saving, but lots of small savings add up.

    Of interest I measured the power of a number of desktop machines at work, and was surprised at the high 'off' power consumed. My Dell 745 used 16w when TURNED OFF. And this was with the lower power mode activated (Wake On Lan disabled). It was about 20W with Wake on Lan enabled. The machine uses about a peak of 80W when running. A Dell prescision workstation (A Dual Socket Quad Core monster) was found to draw 75W when turned off! (And peaked at near 400W when running a compile, and you could probably add another 100W if the graphics card was being pushed as well!).

    Just turning an office full of PC's off at their power points over night will save a significant amount of power.

    maybe you could leave a big paste it note telling whichever person not to off everything.
    if we do care about engery conservation, we would have done it long time ago...why wait till now.
    It's better starting late, then never.
