Earth Day activity - Save our earth

PC power consumption facts
More than 30 billion kilowatt-hours of energy is wasted because many of us simply forget to shut down our computers when we aren't using them. If we could just improve the efficiency of how we use our PCs, the savings in energy costs would be over $3 billion! The CO2 emissions from just 15 computers are equivalent in energy terms to the gas consumption used by one car.

A barrel of oil contains 42 gallons and produces an average 556 kilowatt hours of electrical power. Now consider your computer. A good spec PC can use up to 200 watts per hour. If you have a CRT monitor, it adds a further 80 watts (TFT screens use less). So your system is consuming over 1 kWh of power for every four hours of normal use. If you leave your computer on 24/7, that's the equivalent of a whole barrel of oil every 90 days! If you optimize your computer with LocalCooling and power down when you are not using it you could extend this to over six months!

Remember, if you leave the PC on with just a screen saver, a CRT monitor will still use up to 280 watts per hour of completely wasted power: power that pumps out 1.5lbs of CO2 emissions into the atmosphere for every kWh. If left on for 24 hours that's 9lbs of CO2 every day and 3,285lbs per year. That's more than 1.6 tons of CO2 thrown up into the atmosphere just to keep your one single PC working!

Now if you are reading this at work, how many computers does your company operate every day? Do you switch them off every night or do the PCs have to run through the night? Millions of computers are left switched on 24 hours a day doing absolutely nothing for most of the time..except using CO2 emitting power. And there are more than 660,000,000 PCs in the world today, which is still less than 10% of the world's population!

What can we do?
Today is the Earth Day, everyone is responsible on saving our earth. Please give your hand to support our earth.

Google will first implement the energy saving by reduce the wording on Gtalk (shorthen the "how are you" to "how r u" automatically). This is what we already done daily to simplify our sentances to short form. So, what else can we do some more?

As we known that our Computer are actually consuming the energy. In this cases, we can do something not only to save the energy but also save a cost for ourself.

Hereby introduce a website which providing a software for you to monitor the energy you save by just setting your PC into better mode. At the same time, you are able to know the energy usage from the individual parts from your PC such as Monitor, CPU, hard drive, Graphic card and others.

So far there are aready more then 260 thousands users and total voltage saved already more then 2.7 million kWh.

Let's visit to Local Cooling to save our earth. I believed that you will feel happy when you know how many tree from the earth you are saving. The details of saving will be display and the result will be show on your PC. provide a 3.5Mb free software which supporting both Windows XP & Vista. You will be rank regarding the resource saving and the data will be accumulated with othr user and show to all of the human being on Local Cooling .

You support will be highly apprecated.
