Introduction

As 21st century belongs to computers and electronicitems, energy issues will get a serious ring in the coming

days, as the public debate on carbon emissions, globalwarming and climate change gets hotter. If we thinkcomputers are non-polluting and consume very littleenergy we need to think again.

It is estimated that out of $250 billion per year spent on

powering computers worldwide only about 15% of thatpower is spent computing- the rest is wasted idling.Thus, energy saved on computer hardware andcomputing will equate tonnes of carbon emissions savedper year.

Problem

Conventionally, manufacturing computers includes theuse of lead, cadmium, mercury, and other toxics ingeneral. Usually, computers can contain 4 to 8 pounds oflead alone, according to green experts . It's no wonderthat computers and other electronics make up two-fifthsof all lead in landfills. To counter this growing pollution

threat all over the world due to the growing use ofelectronic device in general and computers in particularthere is a need to look for a eco-friendly computer.


4/9

Designers plan to make future computer more eco-friendlyacross its entire life span, from manufacture to recycling: energy-intensive manufacturing of computer parts can be minimized bymaking manufacturing process more energy efficient by replacing petroleum-filled plastic with bioplasticsplant-basedpolymers which require less OLEDs light-emitting diodes(mercury free) will used. use of toxic materials like lead can be replaced by silver and copper makingrecycling of.

Features

All the basic features of a normal computer available in the market.

Use of solar energy by placing solar panels on the display that would

switch to solar power. 70% more energy efficient.

90% of the material used would be recyclable.

Environment friendly due to use of non toxic materials whileproduction. Complying with various green product standards.

New innovations such as liquid cooledCPUs and use of opticaltechnology.


6/9

Lenovo release 2 new green professional laptops ThinkPad L Serieswhich named Lenovo 412 and LenovoL512.

APPLE

Dell

PC maker announced new business laptops, the ProBook 6445b andProBook 6545b


7/9

strength

New and advanced Technology: The use of latesttechnology such as optics instead of wires and liquid cooled

CPUs. Environment friendly product: By and large this is the

first product of its kind in India that employs the renewablesources of energy to a large extent. It not only focuses ongenerating minimum amount of waste during manufacturing

but also on the health aspect of the end-users. Power: This runs on low power 35W in normal mode,

whereas other computers use 300W, and 4W in standby mode

Period: The life span of these computers is 7-10 years, up to3 times the lifespan of an average computer.
