Green Technology: Future of power generation


Recently concluded Copenhagen conference on climate change and green house emission expressed concern over the amount of CO2 being released. This would in turn heat up the atmosphere and cause global warming that will result in the melting of glaciers and hence the sea level will rise that is a threat to several coastal cities of the world. So one can imagine how the amount of CO2 emissions can cause problems of displacing people from their home. So why do we produce lot of CO2 in the atmosphere? Most of the industries, power generation plants have CO2 as the finally released compound and with greater industrialization more and more pollutants especially CO¬2 are increasing the atmosphere causing lots of damage to the nature. Not only CO¬2 but there are several reasons like burning of fossil fuels, deforestation , rapid urbanization which result all types of land, water and atmospheric pollution and therefore causing a threat to nature and the human life itself. What could be the solution then to reduce these types of emissions and to reduce the damage that we cause to the atmosphere? Should we stop industrialization? Shall we stop generating energy? Although these could be ideal solutions however in today’s world they are impractical. We need to protect our environment. In this situation we are left only with an alternative of using what is now widely known as “Green Technology”


Green technology is a group of innovative methods and materials by which energy can be generated without polluting the environment. This involves use of solar energy, wind energy, wave energy, biomass energy. Unlike the other conventional sources of energy this technology has certain goals; they are as following (taken from 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.

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.

Examples of green technology subject areas

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 encompasses everything from the choice of building materials to where a building is located.

Environmentally preferred 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 preferred 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...
