The two main crises [ie. other
than the actual economy] ailing the world these
days are the food turmoil and the energy turmoil.
There is a serious lack of food among the
producers/exporting nations and as usual there's and
will always be lack of energy. I am not coming
in contact with topic of the unstable present day
economics. In the following paragraphs I want to talk
about the increasing energy needs and also the ways
we can preserve energy, or even better, discover
alternate sources.
We're incessantly depending
on power to fuel the basic needs within our
day-to-day lives. The majority of the power demand is
for possibly electricity or non-renewable fuels.
Let me show a few fancy stats in order
to reiterate my stage. The global electricity
usage in 2005 had been 16,830,000,Thousand
MWHr approximately. And the current day oil reserves
should be present only for the following 40
years before they're going dry. Mind you, this
case is going to be very much within our lifetimes.
[Hopefully..! assuming the actual mortality rate does
not increase all of a sudden!
One thing is for certain, the
consumption is just bound to increase each day.
So what can be done relating to this?
1. We can preserve whatever
little remains and prolong the time of
the fossil fuels operating out/avoid wastage of electrical
power or
2. Discover alternate sources.
You will find basically 3
various conventional sources of electrical power -
1. Hydro-electric energy: as
we all know, this is produced by water inserted at
high pressure which drives turbines that are
coupled to machines. The high pressure is
actually achieved by keeping water in dams/reservoirs.
This is actually the most popular means of energy generation.
There are many hydro tasks that are very successful,
Itaipu dam, that is located between South america and
Paraguay is a good at the.g,.
2. Energy power: this
is produced by burning fossil fuel. I just
can't digest this particular fact. The heat power
thus produced can be used to heat drinking
water, thereby producing vapor to drive turbines.
Energy power stations have become unpopular as
the wastage is fairly high.
3. Atomic power: the
concept is comparable to thermal power with the
exception that nuclear fuel can be used to heat drinking
water instead of coal. Atomic power is allegedly
'clean fuel'. Lots of precautions need to be taken to
ensure there isn't any leakage of rays. [remember
Chernobyl?]
There's the 'Why' as well as
'What'. Now let's visit the 'how'...
Energy Conservation-
1. Charitable organization begins
at home they are saying. Aptly said. First of
all, we must put off just about all equipments when
not in use. [at house or work]. A keep track of or
TV upon standby mode utilizes 50% of its
rated energy.. its not just about your own electricity
bills, its about how exactly much energy many
of us can save together. The quantity of electricity
wasted through one of us per week or so
maybe sufficient to power somebody's house
for at least each day. And that shouldn't be refused.
Because, it all arrives at a price.
2. Energy-efficient equipments should
be utilized; Lighting at houses, or high
energy equipments in sectors.
3. Buildings ought to be built
keeping power conservation in mind. That's minimizing
the use of synthetic lighting and air
conditioning units; and incorporating rainfall water
harvesting and so on.
4. And lastly, city farming
can also be used. This is a technology recently followed
in Asia [ I don't know much regarding this] using
this, the environment in which the farm is situated
could be kept cool, therefore minimizing the
usage of electrical power.
The above mentioned 3 causes
of energy are not green. So there is a serious
need to find alternate resources. There are already
popular techniques -
1. Solar power: there should
be many more photo voltaic fields set up such
as the one in Spain. Here arrays associated with
mirrors are in-line with the sun to mirror and
concentrate sunlight to the top of a structure. There
is a differential gradient and also the mirrors align
using the sun throughout the day. There's a set
of pipes that go around water in and out of
the purpose of concentration. Thus the actual heated
water is actually converted to steam as well as
used to produce electrical power. A very small
property area is used to setup these arrays of
decorative mirrors. The investment is one some time
and the returns tend to be high. The electrical
power thus generated is sufficient to power an
entire town..! For more info on this make sure you
watch 'planet mechanics-solar paella' or 'megastructures-man created
sun' episodes. This is well suited for tropical countries
that receive ample sunshine that can be tapped.
Two. Wind energy: there
is lots of scope with regard to wind turbines to
be placed in many countries. Denmark fulfills
33% of its energy require from wind resources.
This is the largest on the planet. An international
commission could be set up to identify particular
areas where this can be integrated. The installation
and procedure can be given on the contract basis
or even outsourced.
3. Tidal as well as geothermal
energy tend to be yet to be tapped in a
commercial sense and need a lot of specialized development.
Other than these types of, more
and more companies ought to be given carbon credit,
so that they are encouraged to decrease pollution
The present day materials from
the existing essential oil sources shall final
only for 40 much more years. At this price,
and the present reliance by us around
the vehicles that use all of them, there is a dire
want to get to the alternate resources. The
current petrol as well as diesel engines run
at a maximum of 35% effectiveness. This technology has
achieved a saturation and incredibly little can
be done concerning the Internal combustion engines. Within
this scenario, the best we are able to do, at
the floor reality to conserve energy are-
