7. # Green technology
 It means the technology which is environmentally
friendly, developed and used in such a way so that
it doesn’t disturb our environment and conserves
natural resources.
Unlike the technological waves in recent decades,
green technology is almost entirely materials
science based. Relying on the availability of
alternative sources of energy.
 The purpose of this technology is to reduce global
warming as ell as the green house effect.
Its main objective is to find ways to create new
technologies in such a way that they do not
damage or deplete the planets natural resources.
It also expresses less harm to human, animal, and
plant health, as well as damage to the world, in
general.

8. # Why Green technology
 With world leaders carrying out conventions on green technology
and how to curb the rising threat of global warming, the public
anxiety about the phenomenon is at an all-time high.
 Environmentally friendly machines offer great solutions and
encouraging developments in the high-tech sector.
 It’s about time everyone stood up and took notice of the abuzz in
the world about the manmade rise of greenhouse gases.
 Eco-visionaries are already publishing data about the serious
outcomes and encourage everybody to use environmentally
friendly machines.
 For Conserve natural resources and the environment –
Sustainable development

12. Enhanced geothermal energy

13. Enhanced Geothermal Systems
 The overall objective of Enhanced Geothermal
Systems (EGS) is to harness the heat naturally
generated by the Earth to produce electricity.
 In order to do so, wells are drilled into high
temperature basement rock which is naturally
fractured.
 The fracture network is enhanced to create a
reservoir into which additional wells are drilled.
 Cold water is then pumped into the fracture
network, via the wells, absorbing the heat of the
rock as it passes through.

15.  In 2004 scientists Discovered Nano solar Power.
 “On a bright, sunny day, the sun's rays give off approximately
1,000 watts of energy per square meter of the planet's
surface. If we could collect all of that energy, we could easily
power our homes and offices for free”
 Nano Solar managed to reduce production costs from $3
per watt to 30 cents per watt during the manufacturing of
their Power Sheet cells.
 They managed this impressive cost reduction using an
innovative technology which coats metal sheets, as thin as
aluminum foil, with a microscopic layer
of printer ink containing

17. Wave Power
• The Pelamis is an offshore wave energy
converter that uses the motion of waves to
generate electricity.
• The machine operates in water depths greater
than 50m and is typically installed 2-10km from
the coast.
• The machine is rated at 750kW with a target
capacity factor of 25-40 per cent, depending on
the conditions at the chosen project site. On
average one machine will provide sufficient power
to meet the annual electricity demand of
approximately 500 homes.

20. # Wind Energy
 Man has used wind energy for over 2000 years.
In many places, wind energy was harnessed by
windmills for pumping water and grinding
grain.
 Windmills work by slowing down the speed of
the wind. The wind flows over the blades
causing them to turn.
 The blades are connected to a drive shaft that
turns an electric generator to produce
electricity.
 Wind turbines need a constant, average wind
speed of about 14 miles per hour before the
wind turbines can generate electricity. For

21. Green chemistry

22.  The concept of greening chemistry is a relatively new idea
which developed in the regulatory communities and
environment as a natural evolution of pollution prevention
initiatives.
 In our efforts to improve crop protection, commercial
products, and medicines, we also caused unintended harm
to our planet and humans.
 By the mid-20th century, some of the long-term negative
effects of these advancements could not be ignored.
Pollution choked many of the world’s waterways and acid
rain deteriorated forest health. There were measurable
holes in the earth’s ozone. Some chemicals in common use
were suspected of causing or directly linked to human
cancer and other adverse human and environmental
health outcomes..

23. Green Buildings

24.  Green building (also known as green
construction or sustainable 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.
 In other words, green building design involves finding the
balance between homebuilding and the sustainable
environment.
 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.

2. Recycling
 Recycling is processing of used material into new
products to prevent waste of potentially useful
materials, reduce the consumption of fresh raw
materials
 Reduce energy usage
 Reduce air pollution and water pollution
 Lower greenhouse gas emissions as compared to
virgin production.
 Recycling is a key component of modern waste
reduction and is the third component of the
"Reduce, Reuse, Recycle" waste hierarchy.

30.  Sewage treatment, or domestic wastewater treatment, is the
process of removing Contaminants from wastewater and
household sewage both runoff (effluents) and domestic.
 It includes physical, chemical, and biological processes to
remove physical, chemical and biological contaminants. Its
objective is to produce an environmentally-safe fluid waste
stream and a solid waste (or treated sludge) suitable for
disposal or reuse (usually as farm fertilizer).
