Green Technology

Green technology is very new term and has been in news a lot more so since the international environment convention in may, 2008. Green technology is said to be the next big thing in environment after global warming. Environmental technology, green technology or clean technology as it is often put up as is basically the concept of using basic science along with environmental engineering and technology to conserve the natural environment, flora and fauna and counter any harmful elements which tries to disbalance this ecological balance. The idea is make the environment into a much better place to live with the use of science and technology while keeping the solution into the domains of socially acceptable, economically viable and practically feasible to implement.

The most often used Green technological advances are the ones which are now a part of most of our lives. The most common among them are recycling, water purification, sewage treatment, environmental remediation, flue gas treatment, solid waste management, and renewable energy. Apart from this any technology assisting in energy conservation and reducing the waste products shall be implicitly a part of Green technology. As a endeavor to produce energy form new sources which are more clean anaerobic digestion is used a new energy source so are hybrid electric vehicles. Green technology has now been used in green building to assist the basic architecture of the building, green computing is the new off shoring of green technology.



What are the raw materials of Green Technology?
As stated, nearly all Green Technologies rely on the use of new advanced materials. These new materials vary from metals commonly used today in many ways. First, elements on the periodic table such as copper, tin, iron and carbon are stepping aside in favor of less common metals, such as zirconium, yttrium, tellurium and the 14 elements that make of the group of metals known as the "rare earths". For example, batteries that were once made of lead are now made of lithium.

In addition to the use of new metallic elements is the use of these less common metals with common metals to form new super alloys with unique properties, such as scandium-aluminum alloy which can combine lightness, extreme strength and high temperature and corrosion tolerance in a single material. Another example would be newly developed carbides of various metals to create super hard and corrosive resistant materials with interesting properties. Similarly, the use of glass and ceramics in functional components of electronics and energy efficient systems is giving way to the use of crystal structures, semiconductors and super conducting materials.

What are the goals of green technology?

• Sustainability - meeting the needs of society in ways that can continue indefinitely into the future without damaging or depleting natural resources. In short, meeting present needs without compromising the ability of future generations to meet their own needs.


• “Cradle to cradle” design - ending the “cradle to grave” cycle of manufactured products, by creating products that can be fully reclaimed or re-used.


• Source reduction - reducing waste and pollution by changing patterns of production and consumption.


• Innovation - developing alternatives to technologies - whether fossil fuel or chemical intensive agriculture - that have been demonstrated to damage health and the environment.


• Viability - creating a center of economic activity around technologies and products that benefit the environment, speeding their implementation and creating new careers that truly protect the planet.

IN the recent Grease stock an event held yearly in Yorktown Heights, New York more new GREEN TECH was presented like green wireless technology which included:

• Energy efficient radio access networks --- by NEC


• Energy efficiency enhancement in radio access networks --- by Ericsson


• Cliffside and Atom projects --- by Intel


• WiFi with the Bluetooth function --- by Ozmo

Though the Green tech is still very nascent as they have no central "neural form" of technology which is very needful to further grow the scope of the Green technology.
