  What is GreenTechnology? Introduction: • A research to find new ways to use our natural resources without depleting them • A system that incorporates new & innovative methods & materials • A new wave of today’s society • A great gift to upcoming generation Green Chemistry Green Energy Green IT Green Building Green Nanotechnology Why Green Technology? • Limited availability of Fossil fuels • Almost 70 per cent of Indian population depends on agriculture, which is one of the energy intensive sectors. Agriculture consumes about 35 per cent of the total power generated through electrically operated pump sets. It is expected that about 30 per cent of savings is possible through appropriate technology 1 Importance of Green Technology: • Helpful in finding new renewable methods of energy production • Provides effective measures to reduce energy & fuel consumption in our daily works & needs • Provides measures to reduce green house gas emission • It’s long lasting continuous application will surely provide us the same environment that our ancestors enjoyed Branches:

  Companies-proactive about being Green 2 Nokia • Recognized as the world’s most sustainable technology company • Green initiatives at this Finland-based company include an electronics take-back and recycling program, a focus on human rights and multi-year energy use reduction goals Intel • One of Intel’s biggest eco-initiatives is in the green energy arena • According to Forbes, the company uses 1.43 billion kWh of energy annually but 51% comes from renewable sources like solar, wind, geothermal and biomass Cisco • The company has made Fortune’s list of the 100 Best Companies to Work For since the list originated in 1998 • One reason it made 2011’s list is that it has “one of the highest percentages of telecommuters.” Telecommuting saves money in energy costs and reduces tailpipe emissions by eliminating commutes Dell • Aggressive goal of reducing greenhouse gas emissions at the rate by 40% by 2015 • Also focusing on reducing the environmental impact of its product line with a 25% energy use reduction in both its laptop and desktop models

  Green Chemistry •Also called sustainable chemistry, is a philosophy of chemical research and engineering that encourages the design of products and processes that minimize the use and generation of hazardous substances • Environmental chemistry is the 3 chemistry of the natural environment, and of pollutant chemicals in nature, green chemistry seeks to reduce and prevent pollution at its source Eg. • Herbs used in Cosmetic Products • Biodegradable/Compostable Source: plastic.

  Green Energy •Green energy is the energy produced by natural sources i.e. sunlight, wind, rain, tides, plants, algae and geothermal heat which put very small impact on the environment than fossil fuels i.e. oil, gas, coal • About 8% of global final energy consumption comes from renewable resources • 43% of all renewable energy from traditional biomass, mainly used for heating, and • 50% from hydroelectricity • New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 6% and are growing very rapidly • The share of renewables in electricity generation is around 19%, with 16% of electricity coming from hydroelectricity and 3% from new renewables 4 • It encompasses the creation of new ways of generating energy as well as energy efficiency, and the means by which alternative fuels can be developed Source: learn.fi.edu

  Green IT 5 • The green IT or green computing, aims to reduce the carbon footprint generated by the Information Systems business • Green information technology and communication designs or uses products which can reduce the negative effects of human activity on the environment • L.C.D. monitors by Samsung and Dell Source: www.japanfs.org Green strategy by google Source: www.googlegreen.com
• 8.
  Green Building •Refers to a structure and using process that is environmentally responsible and resource-efficient throughout a building's life-cycle • From siting to design, construction, operation, maintenance, renovation, and demolition • This requires close cooperation of the design team, the architects, the engineers, and the client at all project stages 6 Future of Green Building Source: Cost-Benefit Comparison of an Extensive Green Roof Total costs for the client over 40 years $ 33/ sf Preliminary potential savings for the client/building owner $ 32/ sf Additional potential savings for the client/building owner $ 9/sf Total pay back or savings for the client/building owner over 40 years $ 8/sf Source: The economics of Green Roof, by Jorg Breunig

  Green Nanotechnology •Green Nanotechnology refers to the use of nanotechnology to enhance the environmental sustainability of processes currently producing negative externalities • It also refers to the use of the products of nanotechnology to enhance sustainability • It includes making green Nano-products and using Nano-products in support of sustainability Dematerialization: • One of the chief ways nanotechnology might decrease pollution is through dematerialization - the reduction of materials required for manufacturing • Products that can self-assemble out of small components use much less material than ones we build from the top-down, which generate waste and often require solvents and chemical processes • Meanwhile, researchers are also developing ingenious ways to monitor pollution, such as Nano sensors that can biochemically detect contamination and pathogens, in real time and over large areas 7 • Light-emitting diodes(LED) Energy Nano Technology Medicine & Drugs Nano-Biology Technology Optical Engineering Nano Fabrics Cosmetics Bio Engineering

  Development and Analysis 9 • The needs of the society will be met in ways that can be still utilized in future without causing damage to the natural resources or depleting them • Products that can be fully reused or reclaimed will be created, and as result putting an end to the cradle to grave cycle of the manufactured products • Patterns of production as well as consumption will be changed, and that will reduce wastes as well as pollution There will be alternatives to technologies that cause adverse effect to the health of people and damage the environment • Economic activities will be centered on products and technologies that are beneficial to the environment, which will in turn lead to creation of new careers that are not harmful to the planet. The government mandates that such products should be the preferred ones for government purchasing India's CO2 emissions (Gt) CO2 Emission 0.66 +7.3% +4.6% 0.87 1.06 1.29 1.97 1.2 1990 1995 2000 2005 2011 2020 E Source: www.gesi.org Expected Impacts

  Conclusions • Whenused correctly agro-environment-friendly technology has promoted sustainable growth and reduced widening rural-urban income disparities • The application of green technology is the answer for sustainable development but poor countries have not been able to use applicable technology largely because of their inability to afford to the available alternatives • Green technologies assure potency for sustainable growth but significant effort will be required to substitute conventional practices • Alternative energy can be promoted to help low income, marginal and disadvantaged and contribute to rehabilitation of the households displaced by conflict by providing them electricity and cooking fuel • Alternative energy is environment friendly energy source and the possibilities of reducing green house gas emission levels with the promotion of alternative energy, and the savings in the carbon emission levels; thereof has created possibilities of carbon trading in the global market 11
