Slide 1
Energy &Efficiency
Slide 2
43%
We could save as much as 43% of all
the energy we use by improving energy
efficiency.
We’ll be discussing a few ways.
Slide 3
Makes sense…somehow
This is what happens during natural and
artificial power production.
Slide 4
ReplaceRecycleGet REAL
Replace energy-wasting electric motors
Recycling materials
Switch (real :P) from low-efficiency
incandescent lighting to higher-
efficiency fluorescent and LED lighting
In future most of us will go ahead and
get real jobs but of course some of us
will become a scientist. Just kidding.
What we need to invent today has to
be a discovery.

powerNet Energy Loss
Every form of energy used by us commonly
comes down to this- heat and electricity.
Combining heat and power generation
makes it more efficient preventing net
energy loss
Net energy loss involves the total energy
lost due to inefficiency

Introduce the most commonly used
inefficient devices- the threatening 4
Slide 13
The shall fall on our headsAnd maybe even ANGELS
So what do we do?
We don’t have ready solutions yet. Till
we invent something ground-breaking,
we need something efficient.
Slide 14
Insulation
Elimination of air leaks
Heat exchangers
Efficient electric motors
Increased fuel economy
So how do we go about it? Here’s how
Insulation Prevent loss of heat or intake
of cold air leading to higher heat
requirements
Air leaks More energy
Heat exchangers This involves reuse of
heat. Air to air heat exchangers like in
modern air conditioners maximise
utilization of heat produced
Motors Energy produced in individual
motors in small appliances is what is
used ultimately. Even without efficient
machine parts, an efficient motor can
save a heck lot of energy.
Fuel economy Internal combustion
engines- the ones we use today are no
good. Our distant goal is vehicles which
use energy prepared elsewhere. What
we can do till then is make internal
combustion as efficient as possible by
tweaking fuels, machine parts and even
the process of their injection.
Slide 15
Decentralized
Explain what decentralized and micro
power-systems mean
Slide 16
Give examples of what a decentralized
power system shall be like. Innovate.
Slide 17
for the best fuel for your
vehicle
The HUNT
Slide 18
““““Recently I filled my bike with Speed petrol. I calculated the difference for the
same price I get 3.6 liters petrol (Ordinary) where as for Speed© I get only 3.3 litres. So I am getting 300ml
less which is approximately 15km of ride I am missing using Speed©.”
Talk about speed and normal fuel and
their octane rates:
1.Speed which has 90 octane
content
2. Unleaded fuel (petrol) has 85
octane
Slide 19
Octane helps in compression of fuel
during injection. The point is that
Speed or any other treated fuel may
not necessarily be better than unleaded
fuel as compression ratios of vehicles
vary. Using treated fuel for a vehicle
which does not support it will only
make it inefficient.

Slide 21 Scary Movie ©
Speak about how we waste heat in our
homes.

Slide 23
• Today apts are mostly facing
north so it is sensible to have
windows in the south so as the
sun moves from east to west, so
the sun shines in the house all
thru d day
• Huge houses today. So it’s good
to have them painted in light
colors{name of any two light
colors} so the rooms of the
house looks bright
• Have plain transparent glass
windows instead of dark and
designer ones as then the house
remains bright
• In a bedroom if possible have a
big mirror on a dresser as it
reflects light and makes the
room bright
• For a ac [split] have the machine
fixed somewhere in the open like
a balcony or terrace this helps to
cool your room faster
