Turning clock backwards
LankaBuzz
Friends,
I fully endorse what Dr. Jagath V has mentioned below.
I consider the only major sensible thing done by Chandrika (who
virtually devastated the whole country during her tenor as President),
to be the adjusting of time, to save "DAYTIME", thereby reducing
electrical energy consumption.
Dr. Vasanthathilaka has enumerated below some of the issues which need
immediate attention and thorough analysis, before embarking on a
"Stupid" venture.
Saving "Half hour" of Daytime is at least, a saving of 6 % to 12 %
to the consumer of electricity and some saving for Ceylon Electricity
Board, because it is incurring a loss of Rs. 45 Millions daily.
Please scrutinize the calculations I have given below and figure out
each of you, what is the increase in your "Electricity Bill", if
the "Envisaged" change is implemented.
In an "Average" house in an urban area there may be " Seven
Lights" being used daily, regularly.
Assume the following.
1 ) For Kitchen, Toilet and Pantry - 25 Watt Bulbs
2 ) For 2 Bed rooms - 40 Watt Bulbs
3 ) For Sitting room and Dining room - 60 Watt Bulbs
Suppose "Cooking" starts at 5 am and the light is on from 5 am to
6.30 am, ( 1.5 Hrs.)
the amount of energy consumed = 25 X 1.5 = 37.5 (Kitchen )
Assume Pantry and Toilet lights are on from 5.30 am to 6.30 am. ( 1
Hr.)
Energy consumed = 25 x 2 x 1 = 50
Two bed room lights are on for 0.5 Hr.
Energy consumed = 40 x 2 x 0.5 = 40
In the morning total "Energy" consumed = 37.5 + 50 + 40 = 127.5
Suppose in the evening if the lights are switched on at 7 pm
Assume Kitchen and Pantry lights are switched on by 7 pm and off by
9.30 pm ( 2.5 Hrs. )
Energy consumed = 25 x 2 x 2.5 = 125
Assume Toilet light is on for 1 Hr.
Energy consumed = 25 x 1 = 25
Assume bed room lights are on for 2 Hrs. each
Energy consumed = 40 x 2 x 2 = 160
Assume Dinning Room and Sitting Room lights are on for 3 Hrs. each
Energy consumed = 60 x 2 x 3 = 360
Total energy consumed in the evening = 125 + 25 + 160 + 360 = 670
Total per day = 127.5 + 670 = 797.5
With " RE-ADJUSTING OF TIME "
In the morning, Lights are switched on by 5 am and switched off by 6
am.
Kitchen, Energy consumed = 25 x 1 = 25
Pantry and Toilet, Energy consumed = 25 x 2 x 1 = 50 ( Lights on for 1
Hr.)
Bed Rooms, Energy consumed = 40 x 2 x 0.5 = 40 ( Lights on for 0.5 Hrs.
)
Total energy consumed in the morning = 25 + 50 + 40 = 115
In the evening, lights are switched on by 6.30 pm.
Kitchen and Pantry lights are on for 2.5 Hrs.
Energy consumed = 25 x 2 x 2.5 = 112.5
Bed Rooms, lights are on for 2.5 Hrs. each
Energy consumed = 40 x 2 x 2.5 = 200
Toilet, Energy consumed = 25 x 1.5 = 37.5 ( Light on for 1.5 Hr. )
Sitting Room and Dining room, lights are on for 3.5 Hrs. each
Energy consumed = 60 x 2 x 3.5 = 420
Total energy consumed in the evening = 112.5 + 200 + 37.5 + 420 = 770
Total energy consumed = 115 + 770 = 885
Increase in energy consumption = 885 -797.5 = 87.5
Percentage increase = 87.5 x 100 = 11 % ( Approx. )
797.5
Please note that the energy consumed by TV is high but it has been
ignored because all houses do not possess TV's. Also Fans have been
ignored.
In the villages the electrical consumption is much less, which means
the increase may not be felt.
Reliable sources have informed me that the increase in CEB Loss, may
range from 1.5 % to 2.5 %.
Considering 2 % increase in "Loss",
Additional loss to CEB = 45 x 2 = 0.9 Million ( Assume 1 Million )
100
For 1 year additonal loss = 1 x 365 = 365 Million.
I have performed some simple arithmetic and shown, the "unwanted
loss", which is considerable in the long run.
Those who are really interested can follow the simple pattern of
calculations, indicated above, and figure out the best way to reduce
Energy Consumption.
SUGGESTIONS TO CEB
Purchase 10 million worth of "Energy Saving Bulbs" and distribute
these freely among consumers.
Suppose this reduces the CEB Loss per day from Rs. 45 Million to Rs. 40
Million, which means a saving of Rs. 5 Million a day, which is
"SUBSTANTIAL."
CEB Engineers can give serious consideration to what I have suggested
after working out the Cost / Benefit
Ratio.
The Prudent Consumers can evaluate the "Energy Consumption " by
performing the simple calculations and cut the Electricity Bill by
using "Energy Saving Bulbs"

Dear Sir / Madam
Sri Lanka is planning to put back its clocks by half an hour in order
to revert to the earlier time zone of having the same standard time as
in India after using this schedule for 10 years, which was introduced
in 1996 in order to save daytime, there by planned to improve the
productivity and efficiency in all activities related to the general
public.
Putting the clock back in half an hour is not going to help a generally
lazy nation like that of Sri Lanka very much. Now, of course people
wake up early and start working early in the morning and finish their
work very early before it is too dark, in order to go back home and
attend their family responsibilities. This was beneficial for the work
place, transport services as well as for the family.
Most of the employed individuals are using the public transport in
order to go back home early; unlike in the city of Colombo, the public
transport facilities are scanty and grossly inadequate in all most all
the other cities, towards the evening. Even in Colombo, it is difficult
to catch a bus when it is dark. Presently the employees are used to the
currently existing working hours for a decade or so without
interruption.
Unlike in the year 1996, the technological advances used nowadays that
is in the year 2006 are extensive and widespread, and the use of
computers presently in each and every field would make it difficult to
readjust the new time changes without loss of productivity and
efficiency.
Unless we advance the office working hours from present time starting
from 9 AM to 5PM, to that of 8Am to 4 PM, and the school hours from
that of 8AM to 2PM to that of 7.30 AM to 1.30 PM as it was the case
earlier in our time tables in the schools, changing the time in the
clock alone will not have any advantage to the nation. Some
institutions like the hospitals which now start at 8 AM and finish at
4PM may have to be rescheduled to 7AM to 3PM. The shops could be opened
at 8.30 AM according to the planned new time adjustment.
All our pets are working according to their internal clocks; the pets
will find it extremely hard to readjust to the new working hours unless
the working hours of the human beings (Masters) also readjusted
according to the new clock. That is not only applicable to our pets,
most of us who are punctual at work, function according to our internal
clocks. We, as human beings would also find it difficult to adjust to
the new clock, unless there are simultaneous changes in all other
fields of activities in the working environment. Computers and
technological adjustments would also be extremely difficult unless we
plan all these changes meticulously. Most of us are highly dependent on
technological advances nowadays. Savings on energy and electricity is
another factor needs attention when we consider the productivity as
well as the costs and the benefits.
Advancing or delaying the clock alone is not going to serve any purpose
unless this process is accompanied with simultaneous and parrallal
readjustment of working hours in different institutions. Presently, all
the children are used to wake up early and go to school early. If the
schools start late there is no added advantage for the children by new
time adjustments. The time they spend with the parents at home is an
essential part of their personality and mental development when we
consider a growing child. There are many aspects which need extensive
planning ad careful attention prior to implementing any changes to the
standard time used in our country.
Thanking You
Dr V. W. Jagath
