Do you know how much energy your computer uses? Probably not but if
you do a little research to find out then you will realize how important
green computing is. In fact, if you realize how much space old
computers take up in landfills and haw difficult they are to dispose of
then you would also appreciate the idea of green computing. These days
computer recycling is of more importance than ever and everyone
should do their job to help keep the environment clean. Learning a little
more about protecting the environment and computer disposal is
important so you can do your part for the environment.
When it comes to PC disposal you need to know everything there is to
know in order to be involved in green computing. Basically, the whole
green aspect came about quite a few years back when the news that the
environment was not a renewable resource really hit home and people
started realizing that they had to do their part to protect the
Basically, the efficient use of computers and computing is what green
computing is all about. The triple bottom line is what is important when
it comes to anything green and the same goes for green computing. This
considers social responsibility, economic viability and the impact on the
environment. Many business simply focus on a bottom line, rather than
a green triple bottom line, of economic viability when it comes to
computers. The idea is to make the whole process surrounding
computers more friendly to the environment, economy, and society.
This means manufacturers create computers in a way that reflects the
triple bottom line positively. Once computers are sold businesses or
people use them in a green way by reducing power usage and disposing
of them properly or recycling them. The idea is to make computers from
beginning to end a green product.
The solution to green computing is to create an efficient system that
implements these factors in an environmentally friendly way. A good
example would be IT managers purchasing hardware that has been
EPEAT approved meaning that maintenance is reduced, the hardware's
life is extended, and makes recycling the computer easy once it is no
What is Green Technology?
1997 Kyoto Protocol
A landmark event in the history of green technology is the 1997 Kyoto Protocol for the United Nations Framework Convention on
Climate Change. This protocol mandates reducing carbon emissions.
The Kyoto Protocol made computer manufacturers undertake energy audits to calculate the electricity used by the device over its
lifetime and determine the quantum of carbon dioxide emissions to take remedial action.
Restriction of Hazardous Substances (RoHS) and Electrical and Electronic Equipment Directive (WEEE):
The European Union’s adoption of Restriction of Hazardous Substances (RoHS) in February 2003 is a landmark in the history of
green computing. The RoHS directive restricts the use of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls,
and polybrominated diphenyl ether in the manufacture of electronic and electrical equipments.
The implementation of the RoHS was through the Waste Electrical and Electronic Equipment Directive (WEEE) of 2005. This
directive set targets for collection, recycling, and recovery of electrical goods, aimed at reducing toxic e-waste.
These regulations forced manufacturers to use non-hazardous materials in the production of chipsets, processors, and companion
Green Electronics Council’s Electronic Products Environmental Assessment (EPEAT):
The Green Electronics Council established in 2005 focused on special issues related to electronics and sustainability, and sought
constructive paths.
One of the spin-offs of the Green Electronics Council was the Electronic Products Environmental Assessment Tool (EPEAT), a set of
standards based on the IEEE 1680 Standard for Environmental Assessment of Personal Computer products. These standards aimed
at increasing the efficiency and life of the products, and minimizing energy expenditures and maintenance activities throughout the
life of the product.
The development of EPEAT took three years and funding from the U.S. Environmental Protection Agency (EPA), and since then has
created a $60 billion market incentive for greener laptops, desktops, and monitors.

reen technology is the application of environmental science to offer
economically viable solutions that conserve the natural environment and resources, and
curb the negative impacts of human involvement.
The proliferation of data centers required the constant addition of server, cooling and
ventilation equipment that led to an ever-increasing demand of energy and increased
presence of toxic and hazardous substances such as lead, mercury, cadmium, and
others. This made people look at ways to apply green technology in computing to
mitigate the serious environmental and health concerns.
Some examples of the application of green technology in computing include:
•reducing the use of environmentally hazardous materials like CFC, lead and others
•promoting the use of recyclable materials and minimizing use of non-biodegradable
•promoting practices such as energy cost accounting, virtualization, eWaste
recycling and the like
•application of technology with change in lifestyle habits aimed at energy conservation
Application of Green Technology by the Industry
The recent history of green technology in computing is the history of various industry leaders
innovating to comply with regulations.
To reduce their carbon emission liability required by the 1997 Kyoto protocol, companies such as
VIA promoted research on alternative energy sources such as solar cells to power computers. In
2001, VIA established the first-ever cyber community center in the South Pacific powered
entirely by solar technology.
Following the RoHS directives, VIA took the lead to substitute lead with a composite of tin, silver
and copper. VIA’s Enhanced Ball Grid Array (EBGA) package contributed to the development of
power efficient processors, and the Heat Sink Ball Grid Array (HSBGA) package contributed to
the development of power efficient chipsets. These energy-efficient processors produce over
four times less carbon and are compatible with solar-powered devices.
Intel took the lead in virtualization software that allows a combination of several physical
systems into a virtual machine running on a single, powerful base system significantly reducing
power consumption.
Dell increased its investment in renewable energy from wind, solar and natural gas capture, and
offers free recycling to customers.
HP has adopted the use of recycled plastic resin in the manufacture of printers and inkjet print
cartridges in a big way.
Google and Intel started the Climate Savers Computing Initiative in 2007, a nonprofit group of
eco-conscious consumers, businesses, and conservation organizations aiming to reduce carbon
emissions by promoting development, deployment, and adoption of smart technologies and
improve the computer’s power delivery efficiency.
The adoption of green technology in computing has received considerable interest in recent
years as more and more companies realize that going green is in their best interest, both in
terms of public relations and reduced costs.
Manufacturers today aim to improve energy efficiency by creating designs that minimize power
waste and reduce emissions. Companies reduce the amount of toxic waste materials in the
manufacturing process by using recyclable materials and offering to recycle old products.
The application of solutions such as IP video solutions to reduce in-person meetings, the
increased use of Wi-Fi and WiMax networks and other such initiatives are still in their nascent
stages of development and further improvements in such green technology initiatives will help
conserve the world's precious resources in a much better way.
The application of green technology in computing has come a long way since its inception in the
early 1990s. An analysis of the history of green computing however indicates that the the
concept is still in its nascent stage and has a long way to go.
