Temptations TodayAn iPhone, among other
smart phones are one of
the affluent products in
todays market. These will
be seen in hands of justabout anyone these days.
The multiple apps this can
hold entertains anyone of
any age and any
background. Its useful,
sufficient and easy to use,
but do you really need to
have one of them? Is there
a more greener, alternative
choice for everything thats
in the energy consumer?

LEND A HAND BEFORE ITS TOO LATE
Global Warming, Climate Change, Pollution, sound
familiar? It should, because as the human impact on this
planet increases so do these appalling effects.A vital and immense part of daily human life consists of electricity. Humans today depend
on electricity vastly, life feels so much easier and just better with electronic products. The worldtoday is confined with all kinds of electrical products. From the traffic light to your eBooks,
almost all of things are connected with electricity. Life has gotten better, and more advanced,
but the effects on Earth of all the Green House Gas remains unnoticed by many. Practically all
of these electrical goods come from non-renewable energy sources like fossil fuel. Extra carbon
dioxide builds up in the atmosphere from creating electricity and also using electricity. The
additional carbon dioxide produced in the atmosphere generates the damaging effects to the
planet. Earth is warming up rapidly, so the polar caps are melting, extensive droughts, and
drastic weather changes are occurring around the world. There is still some time left to prevent
further damage, but it is only possible if everyone participates. One of the major dilemma's we
are faced with is the constant need to use a phone, laptop or other electrical
device. Instead of taking a walk or reading, people are starting to use
massive amounts unnecessary electricity. Not only is it affecting the
human body, but the usage of these devices produce even more
additional carbon dioxide. If people become more aware of
how much they are using, and cut down to using only essentials,
we will see a positive impact. Nonetheless, profiting from our
renewable resources such as the sun, water, wind and ect. is the
best solution so far. Its very obvious that we cannot just cease to
using electricity, but it is extremely important we try.

Every Hand Counts
Every small thing that you can contribute to helping the
environment. That is the most important skill that the students
in Zarafshas 2013 class had learned. No change is small,
everything and anything can help on the larger scale. Simple
things like turning off your lights, or just not using the laptop
for too long can some how help the planet.
Because you never know, there might be a
million other people around the world doing
the exact same thing, and that would
create a large positive impact. But its
important to remember, every hand counts.
We are forgetting to take care of
the only home we truly have.
The Promising Results
A New LeafZarafsha, an eight grader at ISKL, has dedicated this year
to be the start of a new, green life style at home. After a month
of observing the electricity habits of her family, she saw to it to
make some changes around the household to reduce their
footprint.
The Old LeafDuring the month of August, Zarafsha noticed that
compared to many of the other families at her school, her
families monthly electrical consumption wasnt that faulty.
Looking around her house, she also began to see that herfamily did many things that were environmental friendly
without even realizing it. The cause for the precautions taken
by her family was probably the electricity bill that comes every
month. The expenses for electricity has grown over the past
few years. The Ahmed family were already using minimal
lighting during the night, preferring to use small table over
large wall lights. They used to only use 1 air conditioner at
night, because the father did not live in Malaysia during that
time period. Overall the family did have the basics, but there
was still room for improvement.
Vines of A New LeafZarafsha carefully crafted a detailed plan to help the environment by reducing her
electricity usage. During her month of observation, she looked into many tiny details of
her house to find ways of decreasing her consumption, but still be able to live normally
in the modern age. Then for the next few months she kept track of her monthly
consumption.
Things she changed:
While she was looking around, Zarafsha noticed that almost all the plugs in her house
was constantly on. And there were a lot of plugs in her house, so she decided upon
turning off all the plugs points that werent being used at the very moment, also
reminding her parents that if need be they were allowed to turn on the plug but only if
they could also turn it off when they were done. These sockets, she had seen sucked out a
lot of energy invisibly, without anyone being aware of it. Another she had changed
around the house, was the amount of time laptops and T.Vs were on. Gradually, using
unnecessary technology decreased.
Things she planned to, but did not:
Zarafsha had planned on putting a timer on air conditioners, but failed to do so,because she found out that it was difficult for me to sleep with the air conditioner on, as
the air grew warmer very quickly after it turned off.

So Close, But Not Yet ThereAnalyzing the graph, it is evident to
Zarafsha and her family that maybe they
have not tried hard enough. Although inthe graph, the fitted line has a negative
slope, its not very steep. Also the Ahmed
familys general usage
had increased by a lot
since August. This
might be due to them
moving to a larger
house during the
middle of the year. It
was during that time
period that the family
experienced a high
leap in their
consumption. Though
they slowly came down
to a lower energy consumption, in the end
the consumption was still more than it was
in August. At the beginning of the project,
in August, the familys monthly
consumption was 787 kWh, but in
November is rose to 1035 kWh, which wasa 248 kWh increase. Fortunately though,
the family slowly came down to a monthly
consumption of 987 kWh by April. The
Ahmed family doesnt seem to have a
consistence change pattern, as some
months they would consume more than
the previous, but then they would also
consume less on other
months. But overall, the
family decreased their usage
more often than they
increased, which shows that
there is still hope in changing,
just not very fast. During
these months, the Ahmeds
had began to wake up fromreality and grasp just how bad
the situation was getting. The
saw how difficult it was too let
of some things like too much
T.V, but they also became aware of larger
and worse impact all these electricity was
creating. Time is vital here, because the
way things are going, it wont be long
before theres no going back, there wont
be anything to reduce when there is
nothing.

ETHICAL
A Goal is SetWe thought that being able to use only
300 kWh as a monthly was a good goal for
families like the Ahmeds. To find the exact
time it will take the Ahmeds to get there, we
are going to have to find the equation for
the graph. All we have right now it the fitted
line, which we are going to use.
The equation we are using is;
y = mx + b
The SlopeFirst, we are going to find the slope,
which we are going to get using two pointson the line. To make things easy, we will
pick whole numbers from the x-axis;
(6, 900) and (8, 850)
Using the rise over run method, we find
the difference of the rise and the run
(separately);
900-850 = 50 = -25
6-8 -2
Now we have a part of the equation,
which looks like this now;
y = -25x + b
To be able to solve the problem, we still
have to find out b.
Vertical InterceptThis is the part where we use
substitution, because the two coordinates we
used earlier are a part of the line and will
have the same equation if the equation is
correct.We will use the coordinate
(6, 900)
and substitute them fory and x in the
equation;y = -25x + b
Which would turn out like this;
900 = 6(-25) + b
Now we just solve the equation
backwards.
900 = 6(-25) + b
First you simplify;
900 = -150 + b
Then you add 150 from both sides,
because that is the opposite function
900 +150 = -150 + b
+150
And that is b1050 = b
Which mean, 1050 is my vertical
intercept (y-intercept)
At 300 kWhThe equation we figured out is;
y = -25x + 1050
Now we can plug in the 300 by
replacingy with it, because if you look at
the graph, the the kWh are on the y-axis.
300 = -25x + 1050
And we solved backwards again, but
this time look for x.
300 = -25x + 1050
We subtract 1050 from both sides first,
300 -1050 = -25x + 1050
-1050
Then, we do the opposite of
multiplication and divide 25 from both
sides,
-750 = -25x
-25 -25
And then I have my answer,
30 = x
To check to see if the equation makes
sense, we will put in all the numbers we
found out into one equation like this;
300 = -25(30) + 1050
Multiply first,
300 = -750 + 1050
Then add,
300 = 300
So my answer makes sense because my
equation equals to the number that I
wanted, which is 300.
So this means that it will be taking the
Ahmed family 30 (wow..) months to reach
about 300 kWh as their monthly
consumption, that is if they continue their
monthly electrical consumption as the trend
in the above graph.
