2. Conservation of
energy is conservation of wealth
(Such a discussion started when the power supply was interrupted during the study time.)
पार्थ - Alas! During the spring season, at the
time of examinations itself, there is load shedding.
Indeed, the energy crisis is increasing
day by day.
अथर्व- But I have read that energy
is indeed inexhaustible.
Then how is there an energy crisis?
श्रेया- True, energy is indeed
inexhaustible.
But the sources of energy are limited only. If the cause is destroyed, how will the effect take place?
अथर्व- But what does energy
mean? What are its forms?
श्रेया - Energy means capacity
to work. Heat, light, sound, electricity, etc.
are its many forms.
पार्थ - But what are
its sources?
श्रेया - Its sources are conventional
and non- conventional.
Coal, crude oil and natural gas are the conventional ones.
The
remains of animals
and fossils (remains of plants) that died more than
a million years ago, when
pressed inward due to the great burden
of soil and huge rocks, obtain the form of liquefied gas. That fuel in the liquid
form is called crude oil (unprocessed oil). That itself is (called) black gold.
पार्थ - Great
effort is required for its refinement. Having created a hole in the
ground and extracting it, it is processed. By that processing petrol, kerosene, grease, etc.
are obtained. It is obtained from nature;
therefore its availability is limited.
श्रेया-But the non-conventional
energy obtained from nature is unlimited.
पार्थ-
The sun ,wind, water these are the-great elements. These non- conventional sources of energy are also able to produce energy. Bio-gas is (produced obtained from cow dung, remains of leaves and garbage. Similarly, bio-diesel is produced from castor oil seeds, seeds of
मधुक tree and remains of
sugarcane (bagasse). Energy is also obtained from atoms.
श्रेया- But among these (sources) the solar source
is unlimited, inexhaustible and pollution-free. The thermal power project at Koradi and the
two atomic energy projects
at Trombay
and Tarapur are famous.
Koyana- hydro-electric project is indeed the line
of fortune of modern Maharashtra.
पार्थ- At some places, wind turbines are erected
on mountains. Electricity is
generated with the
help of wind. Is that only the wind energy?
श्रेया- True, that wind energy is free from pollution, safe
and is a source of earning livelihood.
अथर्व-- In this way adopting non- conventional methods, conventional sources should be protected by
all. Due to that wealth will be accumulated, by that alone the progress of the nation will take place.
