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

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.

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.

Speak about how we waste heat in our

homes.

Slide 22

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
