What
kind of new energy sources for tomorrow? How to meet the demand of
incessant increase of population without compromising the future of
earth? Here lies the dreadful challenge.
The
world population has risen from 2.3 billion in 1950 to (6.7 - 7)
billion today and shall probably culminate
in 8 billion in 2025.
But,
actually an African consumes 35 times less energy than a North
American, an Indian 20 times less and a Chinese 10 times less as
well. If energy consumption can be stabilized and lessened because of
better energy saving policies applied in haste in advanced countries,
the energy consumption of developing countries is continuously in
growth.
The
most optimistic statisticians estimate that energy increase in the
world as a whole could be well evaluated at 50 percent in the next
quarter of century.
Until
now 85 percent of global energy consumption was made available by
means of combustible fossils such as coal, fuel oil and gas. But
slowly this kind of natural energy resources shall come inexorably to
an end one day.
Above
all, exploitation of these fuels engenders the emission of CO2
(carbon dioxide) and the amplification of its spread in atmosphere
has become a great threat for the survival of mankind because of the
climatic upheaval due to global warming. Fair enough, every country is
diversifying the energy sources and at the same time adjusting themselves according to the local geographical environment.
For
long time, nuclear power energy development was envisaged by
ameliorating protection against the leak of radioactivity, if there
is any. Also, complete control of fusion, Eolian or wind energy,
solar energy, geothermal energy and hydroelectric power energy etc.
must be undertaken to meet any dearth of energy supply.
In
Nepal it is impossible to rely on rivers because of global warming
there will be possibly no water streaming down from the glaciers of
the Himalayan mountains in a very short span of time.
Meanwhile,
a judicious and efficient brand-new way could be envisaged for the
treatment of city garbage by simply sleuthing around everywhere the
new methods made available by advanced countries, producing methane
gas (CH4) through the process of controlled putrefaction which is
definitely used with success elsewhere all over the world, thus
providing lighting and energy for a whole city.
Some
of the major ecological token-gestures for energy saving:
The
rule of “4Rs”, namely,
1.Re-use
2.Repair
3.Reduce
and
4.Recycle
All
your electrical apparatus must be put off before you go to sleep
because all of them in sleep mode (for example; hi-fi chain, tape
recorder, television, refrigerator, radio-alarm, computer, washing
machine, washer-dryer, dishwasher and ceiling fan etc.) consume in a
year almost as much as a fridge in activity.
You
must use a thermostat to keep the temperature of an apartment around
18°C.
Give
importance to the label quality of an electrical equipment. For
instance, class A apparatus can consume
almost 3 times less energy than a class C; equally applicable to the
consumption of water and the level of soundproofing. Moreover, it is suitable to use more and more led electric bulbs in order to diminish power consumption.
Use
a good thermal insulation of your houses to make the energy saving of
about 10 to 30 percent. Prefer
train to air flight for your voyage within 1500 kilometers.
In
towns and cities, use public transports such as bus, tramway or tube
instead of personal cars. That is one of the ways to produce less CO2
(carbon dioxide) to alleviate greenhouse effect.
To
consume with prudence so as to produce less household and industrial
wastes and they must be biodegradable.
Avoid littering with plastic bags and paper, the sign of
unconsciousness of civility of the citizenry.
In
near future, hydrogen gas (H2) could constitute the principal vector
of energy for multitude of utilization;
mostly for personal vehicles equipped with batteries to produce
power.
Already
many world renowned car-makers are ameliorating the output and
everybody hopes that very soon H2 shall be the major fuel for
mankind. And it is relatively easy to obtain it from the natural
sources. (4H2O = 4H2 + 2O2), where H2O stands for water, O2 for
Oxygen and H2 for Hydrogen.
NB:
Denmark, Germany and France have become expert in energy powerhouse
implantation out of biogas methane (CH4). In France the name of the
society is NASKEO ENVIRONNEMENT whose CEO is Aurélien Lugardon. This
above mentioned society can install the whole plant for the cost of
1.5 million euros (1 euro = 130 NR approx.) in the EU; treatment of
garbage ranging from 3,000 tons to 50,000 tons per year generating
from 100 kW to several MW of electricity, EU standard ISO
(9001 & 9002).
If
Nepal adapts such biogas powerhouses by means of joint venture, it
shall cost relatively less. Those municipalities that want to get rid
of their garbage and at the same time produce energy for lighting
from methane gas (CH4) could consult the respective Embassy, if need
be.
