Green technology is
• the development and application of
products,
• equipment and systems used to conserve
the environment and nature, as well as
minimising and
• reducing the negative effects of human
activities.
8. GREEN TECHNOLOGY
It is important in:
• Overcoming the destruction of the
environment
• Reducing carbon emissions
• Improving human health and lifestyle
• Conserving the country’s natural
resources by applying renewable energy
sources

14. 4.1.2 Relate energy efficiency
with green technology
National Green Technology Policy (July 2009)
Four main pillars:
• Energy – promoting energy efficiency and
seeking energy independence
• Environment – minimising negative effects and
conserving the environment
• Economy – enhancing the country’s economy
through the use of technology
• Social – improving the quality of life for all
15. Importance of the Practice of
Green Technology
• Energy conservation can be increased
• The country’s economy can be
strengthened and wastage can be reduced
• Wastes can be converted into a cleaner
and safer form of renewable energy
16. Energy efficiency
• Refers to the use of less energy to carry out
work at the same or higher rate without
affecting the production and the quality of the
desired outcome.
18. 4.1.3 Sectors in Green Technology

33. 4.2.3 The Application of Green
Technology to Overcome Socio-
scientific Issues in the Energy Sector
The energy sector is the main sector in Green
Technology. Two aspects that are
emphasised in the Green Technology for
solving socio-scientific issues related to the
energy sector are:
a) How energy is produced or supplied
b) Efficiency in usage and distribution of
energy produced
40. 4.3.1 Socio-scientific issues in the
waste and wastewater management
sector
Sewage, chemical wastes and rubbish that are
disposed into the rivers and seas
46. Act. 4.2 (textbook p.61)
Suggested activity:
Gather informationand conduct multimedia presentation
on:
a) Socio-scientific issues in the waste and waste water
management
b) Contributing factors to socio-scientific issues in the
waste and waste water management
c) Application of green technology to overcome socio-
scientific issues in the waste and waste water
management.
47. 4.3.2 Application of Green Technology
to overcome socio-scientific issues in
the waste water management sector
• Prevention and reduction
• Treatment and processing (biological
process)
• Sorting and recycling
• Refuse, reduce, reuse, recycle and
recovery (5R)
48. Note:
The waste and waste water management at garbage

what-is-it/
• The term “technology” refers to the application
of knowledge for practical purposes.
• The field of “green technology” encompasses a
continuously evolving group of methods and
materials, from techniques for generating energy
to non-toxic cleaning products.
• The present expectation is that this field will bring
innovation and changes in daily life of similar
magnitude to the “information technology”
explosion over the last two decades.
