Introduction

Is it really environmentally
Green

?



Our energy is limited

1
st

law of thermodynamics says:

The energy of the universe is constant.

“Energy can be transferred and transformed, but it
cannot be created or destroyed.”

2
nd

law of thermodynamics says:

S
ome energy becomes unusable energy, unavailable to
do work.

“Every energy transfer or transformation increases the
entropy of t he universe.”






Entropy is unusable energy

Part of energy becomes un
-
usable, during its transfer or
transformation

Loss of usable energy is entropy and makes the universe more
disordered






Entropy to indicate environmental
problems


Disordered state represents such as:




Increase in waste





Climate change






H
uman activities in Entropy
concept

General:



Production of steels:

Entropy and Recycling

It
takes energy to reverse high entropy to
low entropy

Energy
goes in one
direction:


low entropy to high entropy


usable
to
unusable


ordered
to disordered




Recycling is in the opposite
direction:


Recycling is very difficult
:


-
> It takes energy


-
> 100 % recycling is not possible

Summary of Entropy concept


All the resources on the planet initially stays as low entropy
and goes to high entropy.


Human's intervene escalates this process, When the
escalation exceeds too much, our economics system cannot
handle it and the resources becomes "un
-
usable"

ICT and Environmental Problems


IT industries are causing more and more environmental
problems


IT does not exist without using energy to run but also to produce
it

“In contrast with many home appliances, life cycle
energy use of a computer is dominated by production
(81%) as opposed to operation (19%).”

(Eric Williams United Nations University, Environmental Science & Technology 38
)


Is E
-
waste Recycling Green?

Pros:

1.
Recycling materials from e‐waste uses a fraction of the
energy needed to make the products from raw materials

2.
It reduces land fill problems




Is E
-
waste Recycling Green?

Contra:

1.
A little of the original waste of materials can be retrieved
to be re
-
usable



Is E
-
waste Recycling Green?

Contra:

2.
Process of recycling is complicated as IT products are
high entropy holder.

Waste heat and Entropy

Data Center:

Data centers uses a lot of energy to operate but also creates a lot of waste
heat.

The management of energy is a very serious issue in Data Center business











Analysis
of a typical 5,000
-
square
-
foot data center shows that demand
-
side computing equipment accounts

for 52 percent of energy usage and supply
-
side systems account for 48 percent

* This represents the average power draw (kW). Daily energy consumption (kWh) can be captured by multiplying the
power draw by 24.

Q. Is Waste Heat Entropy?

Summary


E waste:


IT products are in high entropy state


E
-
Waste Recycling is less evil but not so green


Waste Heat:


IT industries do a lot of transfer of energy, therefore
are entropy maker.


Datacenters are hard to be green and should be more
keen on considering how to be really
green.




Conclusion:

Think of efficiency, feasibility, and Entropy


Most of
Solutions

for green have flaws.


Minimize the energy use in ICT
