2. •Environmental technology , Green
technology or Clean technology is the
application of
• Environmental science,
• Green chemistry,
• Environmental monitoring
• Electronic Devices
To monitor, model and conserve the natural
environment and its resources, and to curb the
negative impacts of human involvement.
What is Green Technology?

5. Responsibility
• Don’t waste electricity – Switch off
electrical equipments when not required.
Avoid electrical equipments consuming
more power.
• Don’t waste water – Never leave taps
open while brushing or washing dishes.
• Don’t waste fuel
• Don’t waste food – Don’t cook extra
food and throw, always keep in mind that
there are million in the world starving
without food.

5.Green Nanotechnology

12. Green Chemistry
Green chemistry, also called
sustainable chemistry, is a
philosophy of chemical research
and engineering that
encourages the design of
products and processes that
to minimize the use and
generation of hazardous
substances.
to reduce and
prevent pollution at its source.

14. Green Energy
•Renewable energy is energy that comes
from resources which are continually
replenished such
as sunlight, wind, rain, tides, waves and g
eothermal heat.
•About 25% of energy consumption
comes from renewable resources
•11% of all energy from solar , 7.6%
biomass.
•3.4% from hydroelectricity.
•New renewables (small hydro, modern
biomass, wind, solar, geothermal, and
biofuels) accounted for another 3% 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.

17. Green Information
Technology
Green IT stands for Green Information Technology.
Information Technology is essentially the design,
implementation and management of computers that both
individuals and businesses use.

19. GREEN BUILDING
Green building ,Green construction or Sustainable building refers to a structure 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. The Green Building practice expands and complements the
classical building design concerns of economy, utility, durability, and comfort.

England, Is covered in mosaic
tiles, which with photovoltaic
panels turned grey due to
pollution.
Bahrain World Trade Center
80-foot turbines projects from a bridge
between towers.

21. Green Nanotechnology
It also refers to the use of the products of
nanotechnology to enhance environmental sustainability.
It includes making green Nano-products and using Nano-
products in support of sustainability.

22. Nano scale Iron: offers one safe
approach for neutralizing chlorinated
organic solvents, organic chlorine-based
pesticides like DDT and polychlorinated
biphenyls (PCBs) ,toxic free.
Dematerialization : One of the chief
ways nanotechnology might decrease
pollution is through dematerialization --
the reduction of materials required for
manufacturing.
Green Nanotechnology
Solar nano foils
Nanosensors can biochemically
detect contamination and pathogens,
in real time and over large areas.
