Search google wisely to reduce CO2 emission

Two Google searches 'produce same CO2 as boiling a kettle'

From http://www.telegraph.co.uk/technology/google/4217055/Two-Google-searches-produce-same-CO2-as-boiling-a-kettle.html

A typical search through the online giant's website is thought to generate about 7g of carbon dioxide. Boiling a kettle produces about 15g.

The emissions are caused both by the electricity required to power a user's computer and send their request to servers around the world.

The discovery comes amid increasing warnings about the little-known environmental impact of computer and internet use.

According to Gartner, an American research firm, IT now causes about two per cent of global CO2 emissions and its carbon footprint exceeded that of the world's aviation industry for the first time in 2007.

Dr Alex Wissner-Gross, a physicist from Harvard University who is leading research into the subject, has estimated that browsing a basic website generates about 0.02g of CO2 for every second it is viewed.

Communist party launches 'China Operating System' to oust iOS and Android

hina officials have launched a national operating system in an attempt to take back control of the country’s computer market from American companies such as Google and Apple. The software has been in development for more than a year, but has been released at a crucial time with revelations about US-led surveillance sparking fears over the integrity of American-designed software.

How to avoid injurious sitting posture at work? Take care of Ergonomics

The impact of poor consideration of these, as well as other, ergonomic elements can be very hazardous to our well-being. Some of the effects include increase chances of suffering from carpel tunnel syndrome, decreased eye sight, cramps in our joints, strain from overworking certain muscles and joints, and decreased blood-flow circulation. Work productivity also decreases when we are in environments that are not designed for proper ergonomics. One other important thing to consider is the lighting levels in the space. I actually did not even think of this as an ergonomic design issue, but it truly is. Our eye muscles are the most used muscles in our entire body. We use our eyes in every situation throughout our entire day. Poor considerations for lighting causes very negative short and long-term effects.
