Example for waste of Energy in
Electric Iron
The wattage of an electric iron lies
between 500 watts to 2000 watts, so
let’s take the average value of electric
iron is 1200 watt.
Let’s assume we will use this electric
iron for 15 minutes every day for 2
months (Peak month of winter session)
Hence, we can calculate the daily,
monthly, and annual power consump-
tion of this 1200 watts clothes iron.
In our case, wattage is 1200 watts and
operational hours are 15 minutes (0.25
hours) in a day, 7.5 hours in a month.
• Daily power consumption of a
1200watts electric iron (15 mins) =
1200 watts X 0.25 hours = 0.3 kWh
•
Similarly,
the
Monthly
power
consumption of a 1200 watts electric
iron (15 mins/day for 30 days) = 1200
watts X 7.5 hours = 9 kWh (9 Unit).
As you can see, 9 unit/month is wasted
in using electric iron for ironing our
clothes.
We should always use gadgets with
appropriate manner in which we feel
comfort. I have seen many people use
blanket while using the AC, AC has
thermostat setting through which we
can control their temperature. We have
to use AC at our comfortable zone. We
have to keep our thermostat setting at
26°C, which is our comfortable zone. It
is not necessary to run your AC at 21°C
& wear blanket Always use gadgets in
smart way, it will help you to reduce
your electricity bills. All small changes
in the usage will definitely make your
pocket happy and help the society in
reducing the global warming contribu-
tion .
3. Replacement of Gadgets with
Energy Efficient Gadgets
With the advancement of new technolo-
gy, most of the energy efficient appli-
ances are available in the market.
Replace your old appliances with more
efficient appliances which consume less
power but will give you same or more
energy.
Energy efficient appliances like replace
60-watt standard incandescent bulb
with 15-watt LED bulb (reduce electric-
ity consumption by 75%)

REPLACED WITH LED BULB
We can reduce energy consumption by
40-60% by using efficient appliances.
4. Use of Renewable Energy (Solar
Energy)
We can reduce our energy consumption
by ARE (Avoid, Reduce & Energy
Efficient) through which we can reduce
our electricity bills but next “R”of
thumb rule is totally different from
these. Fourth alphabet “R” means Use
of Renewable Energy (Solar Energy)
i.e. solar PV at rooftop of our house

TO
RENEWABLE
ENERGY (SOLAR ENERGY)
As we know very well, most of energy
is generated by coal burning process
which generates energy as well as CO2
also which is harmful for our mother
earth. As coal is limited, definitely it
will get empty in future. If every family
become generator of their own energy
means every family generate their own
energy by itself, then our mother earth
can be saved easily as well as save
electricity bill.
Advantages of Solar Energy
1. Solar energy has become Viable
solution
2. Cost-Effective
3. All
its
components
are
easily
available in the market
4) Low Maintenance
5) With battery storage, we can give
away our electricity connection (No
Bills)
6) Can be installed on rooftop of any
building
7) Can be used independently even for a
household
8) Sunlight can be found everywhere on
earth, no need to move on.
Due to these all advantages, we should
adopt solar energy as soon as possible.
3.0 CONCLUSION (RECOMMEN-
DATIONS & SAFETY TIPS)
1. THUMB RULE OF ARE-R TO
REDUCE ELECTRICITY BILL
First alphabet “A” means Avoid use of
electricity when not needed/ when not
in use.
Second alphabet “R” means Reduce Use
of Electricity (Use Gadgets Smartly)
Third alphabet “E” means Energy
Efficient (Replacement of Gadgets with
Energy Efficient Gadgets)
Fourth alphabet “R” means Use of
Renewable Energy (Solar Energy).
