2. What is Green Technology?
Environmental
technology or “green
technology” is the
application of the
environmental science to
conserve the natural
environment and
resources, and by
curbing the negative
impacts on human
involvement 2
3. HISTORY
The importance of green technology
was made evident when computing
attained critical mass in the year
1990s. The late 1990s and early 2000
witnessed many regulatory milestones
and the recent years witness
companies innovating to incorporate
green technology.

6. The most
impressive feature
of the new
Bahrain World Trade Cen
is, no doubt, the
three massive wind
turbines situated
between the two
towers comprising
the main building.
Each of these 80-
foot turbines
projects from a
bridge between
towers. 6
7. CIS Tower, Manchester
England. Was covered in
mosaic tiles, which with
photovoltaic panels turned
grey due to pollution.
Tiles replaced, costing
£5.5 million.
Began feeding National
Grid in 2005.

8. Why are companies choosing
to go Green?
Because people are requesting
environmental technologies
Example: hybrid versus non-hybrid most
people want the hybrid for a variety of
reasons
Green is a trend that is going to be around
for a while. It will stay important as long as
climate change is an issue

9. GREEN BUILDING
Green Building is the practice of increasing
the efficiency of buildings and their use of
energy, water and materials and reducing
building impacts on human health and the
environment through better design,
construction, operation, maintenance and
removal - the complete building life cycle.

10. How people can contribute
to Green Building:
Think small
Heat with the sun
Use renewable energy
Conserve water
Use local/natural materials
Recycle materials

11. Green Energy Companies in India
1. Suzlon Energy: Suzlon is of course the
first company that comes to mind. They
are one of the leading wind energy
companies in India that is one of the
better known alternative energy
companies in India. 11 11
12. 2. Orient Green Power Limited: This is a
company that recently had its IPO, and
is primarily engaged in the Wind and
Biomass energy space. Currently wind
constitutes the majority of their energy
portfolio, so this is another one of
India’s wind energy companies. 12 12
13. Solar Power
Heat Transfer
•oil in a pipe is heated, then runs through
reservoir of water. Heat from oil causes water
to boils, creating steam which turns turbines.
Photovoltaic (common solar panel)
•photons from sunlight knock electrons into
higher sates of energy causing potential voltage
difference (electricity).
13
14. Water Power:
Hydroelectricity
Rivers are dammed, and water is released
slowly
Force of rushing water creates electricity
Environmental concerns of building dams
14
15. Wind
Wind rotates turbines to create electricity.
Has potential to take over all of our
electricity needs (on 13% of all land area)
15
16. Geothermal
Pipes are routed near geothermal
activity. Boiling creates steam, which
turns turbines.

17. Driving Trends
Since 1770, miles increased
150% while population
increased 40%
200 million vehicles in the
U.S.
700 million in the world
By 2008, one million hybrid
gas-electric cars in the U.S.

18. Total Impact of Green Vehicles
Smaller, lighter cars
Fewer materials
Decreases emissions
Eases environmental
impact
No proven reduction in
car’s safety! 18
19. Health Effects
Automobile pollutants have an impact on health
and the environment
Respiratory problems
Impair the body’s immune system
Increase a person’s risk of cancer
Birth defects, low birth weight, deaths
19
Asthma
20. Benefits
Reduces local air pollution
Offsets greenhouse gases
Conserves energy
20
Reduces the need for dry-cell battery disposal
21. Conclusion
More and more corporations are
jumping on the green bandwagon.
It’s trendy
It’s important!
It’s good for the environment
It saves companies money
It benefits our health 21
