Use your computer efficiently
A recent controversial report claimed that just two google searches could emit as much carbon dioxide as a kettle boiling enough water for a cup of tea; roughly 7g of CO2.
Google refuted the study, putting the figure at 0.2g per search. That doesn’t sound a lot until you consider that between us, we do over 200 million searches per day.
I’m not expecting you to turn your computers off after reading that, but here are some tips to make your internet surfing as eco friendly as you can:
Keep your old computer
It might sound strange, but hang on to your existing computer for as long as you can. It’s tempting to rush out and buy the latest ‘green’ or ‘energy efficient’ laptop, but when you consider the manufacturing ‘cost’ to the environment of a new machine; it’s better to keep the one you have for as long as possible.
Change your power setting
Set your power savings to 15 minutes or less. This means your monitor and hard drive will go into sleep mode if they are not used for 15 minutes.
Energy star believe you can cut the electricity used by your PCs roughly in half, by making good use of power saving management. This could equate to £50-150 per PC annually.
Energy saving search engine
Try using an energy saving search engine, such as Blackle. It is said that an all white web page uses about 74 watts to display, while an all black page uses only 59 watts. Estimates are that if we all switched to a Black Google, we could collectively save 750 Megawatt-hours a Year.
According to Blackle, every time you search using their search engine, you save energy because the screen is predominantly black.
If you leave your personal computer on standby, it’s always drawing some kind of power. Depending on what kind of mode you’re in that power can be anywhere between five watts to 60 and beyond.
According to Scott Richards from power supply manufacturer Antec; if a million PC users switched to a more efficient power supply, it would save almost the equivalent of 250 thousand litres of gasoline a day.
The simple message is; turn your computer completely off at the end of the day; don’t leave it on standby. If you’re likely to forget to turn your peripherals off standby, use an intellipanel.
Recycle your computer
At the end of its useful life, recycle your computer. Either offer it on Freecycle, sell it on eBay or send it to an approved recycling scheme.
