8. Q&A
1. What is
Energy?
Energy in layman's
terms is the ability to do work. It can also be termed as the work done or
consumed in carrying out a process.
Energy can
be expended in various forms. The work done in moving from place to car either
by foot or car, the turbine at power plants which converts energy to produce
electricity. In other words, today's processes involved the consumption of
utilization of energy from your day-to-day movement as stated earlier, to your
phones and home appliances down to electricity generation and launching of
satellites into space that provide accurate location. Therefore, energy is a
topic of serious concern, and must be treated carefully or the implication of
its misuse, will aggravate serious trouble.
2. Forms
of Energy.
Energy can
neither be created nor destroyed, but can be transformed from one form to the
other. This statement is also the "first law of thermodynamics" and
it implies that energy exists around us in the first instance and this energy
is being transformed from one form to the other depending on how we need it.
Examples:
Energy exists statically in the molecules that make up premium motor Spirit
(PMS), i.e., petrol. When the spark
plug in your cart ignites the fuel, it burns and turns into gas, this thermal
energy introduced instigates kinetic energy in the had molecules which push
your piston, which in turn rotates your crankshaft which is connected to the
connecting rod and eventually rotates your tires and allow you to take off. The
unneeded gas is thrown to the exhaust pipe and right out into the atmosphere in
almost all cases. This shows that energy can not be destroyed.
The same
thing happens during digestion, Chemical energy in your food is combined with
oxygen to release energy which is needed by your body for mechanical work and the
waste food is passed out which still contains energy can be used for
electricity generation.
In the
first instance of your car, the following transformations take place.:
Chemical -
thermal- mechanical- thermal
In the
digestion we have : chemical - thermal - mechanical.
Other
forms of energy include, electrical, luminous (light), nuclear, solar and so
many more...
2. Forms
of Energy.
Energy can
neither be created nor destroyed, but can be transformed from one form to the
other. This statement is also the "first law of thermodynamics" and
it implies that energy exists around us in the first instance and this energy
is being transformed from one form to the other depending on how we need it.

unneeded gas is thrown to the exhaust pipe and right out into the atmosphere in
almost all cases. This shows that energy can not be destroyed.
Sources of
energy are different from forms. While forms define the media in which energy
can exist in, sources imply where we can obtain energy.
Sources
include:
1. Water
(Hydro)
2. Sun
(Solar)
3. Nuclear
(Radioactivity)
4. Biomass
(Waste and plants)
5. Fossils
6. Food
7. Wind
8.
Volcanoes and the earth's core of which some people don't know that..
4. What is
Clean Energy?
Clean
energy, may have a direct meaning in your mind. You may think it's renewable
energy, like me, for some it's to be free from emissions for another it's to be
produced with least resources.
However
it's definition can be classified into three or even more school of thoughts.
I'll highlight three.
1. It must
be free from emissions of chemical substances, and exhibits less waste of
energy either in transformation, conversion or utilization process.
E.g Solar,
wind
2. If it
is renewable. In there words, if it can be recovered or recycled or gotten from
a natural source that can't finish. They may require much energy to be
utilized, but so long as they can be recycled. (E.g biomass.) Asides biomass,
Renewable energy include, wind, solar, Hydro, Geothermal.
3. If it's
consumes the most minimum resources in its conversion or utilization process.
Therefore even coal can be termed Renewable as coal is relatively cheap.
Clean-coal
as they call it as even Obama uses this term very broadly.
However
this 3rd classification can be also out better termed efficient energy.
The term
"clean energy" is termed is a rather nebulous term, as there is no
standard agreed definition.
Renewable
energy: wind, water, solar, biomass, Geothermal.
Less
emissions: nuclear, hydrogen, natural gas.
However
since nuclear is dangerous, it is termed unclean. And natural gas supply is
finite, it could be termed unclean.
5. Effects
of unclean energy:
Green
house emissions which cause global warming which in turn induces climate change
and causes floods, draughts, and different other climate conditions which make
living on our earth quite unbearable.
Unclean
energy can also be instigated domestically in our homes. From using improper
refrigerants in our refrigerators and cooking with firewood and allowing food
to burn or cook for long.
A lot of
people are guilty of that
So we
should all try to reduce our contributions to climate change in our domestic
homes by not wasting energy
6. Effects
of energy on Quality Education
Draughts
and famine and floods, affect the student learning cannot hold in such
conditions.
But there
are other ways by which clean or unclean energy could affect education.
1. Because
clean energy, is economical, it allows more of government's resources to be
channelled to the education sector and improve the standard of education.
2. By
adopting clean energy, energy is always available, and so electricity is being
provided for students to carry out majority of their work as adequate
electricity is essential for quality education co-curricular activities and
skill acquisition and even for SMEs. As some students are entrepreneurs.
3. The
fourth stresses on how clean energy education can be imbibed into education. As
knowledge on clean energy will make future generations energy conscious and
implications of unclean energy will be reduced.
7.
Conclusion.
I believe
that by this, we're now aware about energy, clean energy, it's possible
definitions, and it's importance.
Thank you.
