you know that housewives can save
upto 30% of cooking gas or kerosene
by following a few simple ‘fuel–saving
below are a few tips on how to minimize
losses and get value for the money
you spend on cooking gas or kerosene
A few minutes of planning
ensures a big fuel saving
time, you can avoid an idle flame
if you prepare and keep all materials
required for cooking within reach,
before lighting the stove.
Experiments here revealed
that keeping the flame of the
larger burner burning unnecessarily
in a gas stove, results in a waste
of 135gs. of gas or 130
paise per hour.
Even a few paise saved
everyday will amount to a sizeable
saving by the end of a month.
Light your stove only after you have
kept all the ingredients within
your reach and ready for cooking.
Put off an idle flame at once.
cooking is one of the fastest and
most economical ways of cooking. Experiments have
shown fuel (kerosene or cooking
gas) savings of 20% on rice, 46%
on soaked gram dal and 41.5% on
meat, as compared to ordinary cooking. The savings in
cooking time were equally high. To obtain further
savings from a pressure cooker,
use the separators of the cooker
to cook different items such as
rice, vegetable and dal, all at
the same time. Just think of the
fuel and money you will save! And
have your entire meal ready quickly.

quantity of water used differs
for various dishes. And even for the
same dish, different housewives
use varying quantities of water.
Since water is extensively
used in cooking, you should remember
that surplus water wastes fuel. Besides, when
the excess water is drained subsequently,
precious nutrients are lost. An experiment
on cooking rice with double the
required quantity of water has
revealed that fuel consumption
increased by 65% So use only the
optimum quantity of water for
Surplus water consumes additional
which could otherwise be saved.
when boiling starts
a vessel’s contents reach boiling
point, a low flame is enough to
keep them boiling. Addition of more
heat at the boiling stage causes
further evaporation of the liquid
without serving any useful purpose. Hence, when water
or any other liquid is boiling,
reduction in the flame will reduce
wastage. This is possible
in a gas stove by turning the knob
to ‘simmer’ position or in a kerosene
stove by lowering the wicks. Experiments conducted
have revealed a saving of 25% fuel
when the flame was reduced after
boiling had started. Try it yourself.
You will find that the time taken
to cook is just the same.
Always reduce the flame once
Soak before cooking
have shown that soaking ingredients
such as dal and rice for various
intervals of time before cooking
saves fuel. 250 gms of kabuli
chana (chick peas) when soaked overnight
in water consumed 22% less fuel
as compared to the fuel required
for the same quantity of unsoaked
Sizeable savings in fuel are

wide vessels save fuel
visible flame touching the sides
of vessel wastes fuel since it gives
out heat to the surroundings.
But if you cover the flame as much
as possible by using a broad vessel,
you will save fuel.
Our tests have established
that for most stoves, a vessel of
25 cm diameter is ideal for cooking. A vessel of this
diameter tends to cover the flame
completely. Where a narrower
vessel cannot be avoided, try and
reduce the flame so that it does
not creep up on the sides of the

vessel. Do not use vessels which
are narrow as they allow the flame
creep up on the sides.

vessel of 100sq.cm. opening, containing
hot water at 96°C would waste 7.2 gms of gas
The heat loss would increase
by 2-1/2 times if there is wind
blowing through the kitchen. If the vessel is covered
by a lid, the heat loss would drop
appreciably to 1.45 gm of gas per
hour as heat is retained within
Always place a lid on an open
vessel or pan.
small burner saves fuel
cooking gas stove has a big burner
and a small burner. The small burner consumes
6% to 10% less gas than the big
burner! An experiment on cooking
250 gms of potatoes revealed that
the small burner consumed 6.5% less
gas but look 7 minutes more than
the big burner. Similarly in a
kerosene stove, by cooking at lower
flame you will use less fuel.
You can now imagine how much
fuel is being avoidably wasted.
True, the small burner of
the lower flame takes a little more
time to complete cooking, but then
you are not always in such a hurry
that you can afford to waste fuel.
Use the small burner or lower flame
more often, as the case may be
especially when you have time to
A clean burner helps
is important to clean the burner
of your gas range regularly and
trim or replace the wicks of the

food to reach room temperature before
milk, frozen meal or any other cold
foodstuff from the refrigerator
should not be taken straight to
the cooking pot. Keep it out of the refrigerator
for some time before putting it
on the stove.
Very cold food consumes a
larger amount of fuel.
Plan your meal
all members of the family eat together,
which signifies togetherness and
increases joy, frequent reheating
of food before serving can be avoided.
If eating together is not
possible, store cooked, hot food
in insulated containers to serve
it hot later.
