3. What is Green Technology?
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

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:

4. 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

5. 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.

6. 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

7. 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

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

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

9. 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

11. 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

13. 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
