13. INTRODUCTION
All the renewable energy sources are principally derived
from the enormous power of Sun's radiation.
www.naveedurrehman.com 13
14. INTRODUCTION
These renewable energy sources are at once, the most
ancient and now, the most modern forms of energy used
by humanity.
www.naveedurrehman.com 14
15. INTRODUCTION
Solar power is one of the ultimate sources of energy upon
which early human societies were based.
www.naveedurrehman.com 15
16. INTRODUCTION
When our ancestors first used fire, they were harnessing
the power of photosynthesis which is a solar driven
process by which plants are created from water and
atmospheric carbon dioxide.
www.naveedurrehman.com 16
17. INTRODUCTION
Societies went on to develop ways of harnessing the
movements of water and wind to grind corn, irrigate crops
and propel ships.
www.naveedurrehman.com 17
18. INTRODUCTION
Both the natural movements of water and wind are caused
by solar heating of the oceans and atmosphere.
www.naveedurrehman.com 18
19. INTRODUCTION
As civilizations became more sophisticated, architects
began to design buildings to take advantage of the Sun’s
energy by enhancing their natural use of its heat and light,
so reducing the need for artificial sources of warmth and
illumination.
www.naveedurrehman.com 19
20. INTRODUCTION
Technologies for harnessing the power of Sun, water and
wind continued to improve right up to the early years of
the industrial revolution.
www.naveedurrehman.com 20
21. INTRODUCTION
However, by then the advantages of coal,
the first of the fossil fuels to be exploited
on a large scale, had become apparent.
www.naveedurrehman.com 21
22. INTRODUCTION
These highly-concentrated energy sources soon displaced
wood, wind and water in the homes, industries and
transport systems of the industrial nations.
www.naveedurrehman.com 22
23. INTRODUCTION
Today the fossil fuel trio of coal, natural gas and oil provide
over 80% of the world’s energy.
www.naveedurrehman.com 23
24. INTRODUCTION
Concerns about the adverse environmental and social
consequences of fossil fuel use, such as air pollution, oil
spills, mining accidents, deforestation and about the finite
nature of supplies, have been voiced intermittently for
several centuries.
www.naveedurrehman.com 24
25. INTRODUCTION
But it was not until the 1970s,
with the steep price rises of
the ‘oil crisis’ and the advent
of the environmental
movement, that humanity
began to take more seriously
the prospect of fossil fuels
‘running out’, and the
possibility that their
continued use could be
destabilizing the planet’s
natural ecosystems and the
global climate. www.naveedurrehman.com 25
26. INTRODUCTION
The development of nuclear energy following World War II
raised hopes of a cheap, plentiful and clean alternative to
fossil fuels.
www.naveedurrehman.com 26
27. INTRODUCTION
However, nuclear power development has stalled in some
countries in recent years, due to increasing concern about
safety, cost, waste disposal and weapons proliferation,
although in other countries nuclear expansion is
continuing.

29. INTRODUCTION
Now, what is a Sustainable Energy Source?
Sustainable energy source is one which help this
world in meeting its present needs without
depleting of serving next generation’s needs.
www.naveedurrehman.com 29
32. INTRODUCTION
At present, oil and gas present at large scale and
thus are sustainable energy sources.
www.naveedurrehman.com 32
33. INTRODUCTION
What is a Renewable
Energy Source?
Renewable energy
source include such a
natural source which
can be replaced by
natural ecological
cycles. That is, they
renew thus never gets
deplete.
