What Is Green Technology?
Its Importance. Its Objectives.
The field of Green Technology encompasses a continuously evolving group of methods and materials, from techniques for generating energy to non-toxic cleaning products.
The present expectation is that this field will bring innovation and changes in daily life of similar magnitude to the "Information Technology" explosion over the last two decades. In these early stages, it is impossible to predict what "green technology" may eventually encompass.
The goals that inform developments in this rapidly growing field include:
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. An emphasis on true recycling—not downcycling.
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.
Some Examples Of Green Technology Subject Areas
Energy
Perhaps the most urgent issue for green technology, this includes the development of alternative fuels, new means of generating energy and energy efficiency.
Green Building
Green Building, sometimes referred to as Sustainable Building, encompasses everything from the choice of building materials to where a building is located. The Leadership in Energy and Environmental Design Green Building Rating System (LEED) is a voluntary, market-based rating system for defining the elements that make a building "green" and to quantify how green a building is in comparison to other buildings.
Environmentally Preferable Purchasing
This government innovation involves the search for products whose contents and methods of production have the smallest possible impact on the environment, and mandates that these be the preferable products for government purchasing.
Green Chemistry
The invention, design and application of chemical products and processes to reduce or to eliminate the use and generation of hazardous substances.
Green Nanotechnology
Nanotechnology involves the manipulation of materials at the scale of the nanometer, one billionth of a meter. Some scientists believe that mastery of this subject is forthcoming that will transform the way that everything in the world is manufactured. "Green Nanotechnology" is the application of green chemistry and green engineering principles to this field.
