A Canadian company, Useful Inc. (www.userful.com) have come up with a solution that turns 1 computer into 10 – Discover Station. Quickly becoming the standard for green computing worldwide, Discover Station leverages the unused computing power of modern PC’s to create an environmentally efficient alternative to traditional desktop computing. Multiple users can work on a single computer by simply attaching up to 10 monitors, mice and keyboards. This makes it possible to reduce CO2 emissions by up to 15 tons per year per system and reduce electronic waste by up to 80%. Useful has recently stated that in the last year their software has saved over 13,250 tons of CO2 emissions, the equivalent of taking 2,300 cars off the road.
Problems of Electronic Waste
Electronic waste is an increasing problem globally due to the quick obsolescence of electronics, which make up a staggering 70% of all hazardous waste. Computer waste is high in many toxic materials such as heavy metals and flame-retardant plastics, which easily leach into ground water and bio-accumulate. In addition, chip manufacturing uses some of the deadliest gases and chemicals known to man and requires huge amounts of resources.
In an average year 24 million computers in the United States become obsolete. Only about 14% (or 3.3 million) of these will be recycled or donated. The rest - more than 20 million computers in the U.S. -- will be dumped, incinerated, shipped as waste exports or put into temporary storage to be dealt with later. We never stop to consider what happens when our laptop dies and we toss it. The reality is that it either rots in a landfill or children in developing countries end up wrestling its components apart by hand, melting toxic bits to recover traces of valuable metals like gold.
Wasting Electricity
The manufacturing of a computer consumes 1818 kw/h of electricity before it even gets turned on and when running, a typical computer uses 120 watts. Research shows that most PC’s are left idle all day, and many of them are left on continuously. Every time we leave computers on we waste electricity without considering where that electricity comes from. The majority of the world’s electricity is generated by burning fossil fuels which emit pollutants such as sulphur, and carbon dioxide into the air. These emissions can cause respiratory disease, smog, acid rain and global climate change.
