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

1Importance 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

chemistry of the natural

environment, and of pollutant

chemicals in nature, green

chemistry seeks to reduce and

prevent pollution at its source

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

• 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

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

Green strategy by google

• 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

Green Building6

Future of Green Building

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

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

Development and Analysis9

• 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

Conclusions

• When used 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
