I take this opportunity to express my profound gratitude and deep regards to my

guide Mrs Tan Gien Pei, for exemplary guidance, monitoring and constantencouragement throughout this assignment. The blessing, help and guidance given

from time to time had carried me a long way in the journey of completing this

assignment.

I also take this opportunity to express a deep sense of gratitude to my parents, Mr

and Mrs Arasu for their valuable information and guidance based on daily lifematters, which helped me in completing this task through various stages.

I am obliged to my lovely friends for their cordial-valuable information in their

respective views. I am grateful for their cooperation during the period of my

assignment.

Lastly, I thank almighty God, teacher, parents, and friends for their constant

encouragement without which this assignment would not be possible.

Sincely,

Introduction

Solar energy in one form or another is the source of nearly all energy on the earth. Humans,

like all other animals and plants, rely on the sun for warmth and food. However, people also

harness the sun's energy in many other different ways. For example, fossil fuels, plant matter

from a past geological age, is used for transportation and electricity generation and is

essentially just stored solar energy from millions of years ago. Similarly, biomass converts

the sun's energy into a fuel, which can then be used for heat, transport or electricity. Wind

energy, used for hundreds of years to provide mechanical energy or for transportation, uses

air currents that are created by solar heated air and the rotation of the earth. Today wind

turbines convert wind power into electricity as well as its traditional uses. Even

hydroelectricity is derived from the sun. Hydropower depends on the evaporation of water

by the sun, and its subsequent return to the Earth as rain to provide water in dams.

Photovoltaic (often abbreviated as PV) are a simple and elegant method of harnessing the

sun's energy. PV devices (solar cells) are unique in that they directly convert the incident

solar radiation into electricity, with no noise, pollution or moving parts, making them robust,

reliable and long lasting. Solar cells are based on the same principles and materials behind

the communications and computer revolutions, and this CDROM covers the operation, use

and applications of photovoltaic devices and systems.

PART A

Question 1

Answer:

According to my view, I think it is true that more sustainable, cleaner and saferworld can be created by making wiser energy choices. This is because nature

resources behind every technology are not realized by human. Energy here

meant is renewable energy such solar energy, wind power and etc. These

energies are trapped and applied in most of the developed countries in order

to reduce the amount of electricity (kW) used. By using renewable energy, we

can avoid pollutions as well as can manage to have a healthy-living

environment.

Question 2

Answer:

Types of renewable energy are:

Solar Energy- Is radiant light and heat from the sun.

- Widely used in Japan.

Hydropower

- Power derived from theenergy of falling water and running water.

- Widely practised in China.

Wind Power- is the conversion ofwindenergy into a useful form of energy, such as usingwind turbines to

produceelectrical power,windmills for mechanical power, wind pumps forwater

pumping ordrainage,orsails to propelships.

- Well known in Denmark.

Wave (Ocean) Power

- Is the transport of energy byocean surface waves,and the capture of that energy to do

usefulworkfor example,electricity generation,water desalination,or thepumping of water (into

reservoirs).

Geothermal Energy- Isthermal energy generated and stored in the Earth. Thermal energy is the energy that

determines thetemperature of matter.

- Well known renewable energy in Iceland.

Question 4 - b

(b) Based on the table, plot the curve of

your conjecture.

(Turn to next page to refer the graph I)

Conjecture: When

increase, then V increases too. A constant increment in the

value of

increases the value of V where the graph does not curve

downwards (negative value) and it maintains its positive curve

shape. Since, there is no negative values produced in V, hence the

graph formed is not a quadratic graph.

panel located at Kuala Lumpur at 12:00 (solar time) on the 31stof August

2010. The panel is tilted at 45from the horizontal and pointed at south.

[ The latitude of Kuala Lumpur is 3.13N ]

To find the angle of incidence, between the suns radiation on the solar panel

surface and the normal to the surface,

PART B

(a) What are the common renewably energy sources in Malaysia? Find out the

location of 3 renewable energy installations in Malaysia and how much

power each installation can generate? If an average family needs 3kW of

power, how many families can each renewable energy installation support?

Types of energy Location of installation Output current Number of families

Pulau Perhentian Kecil, Terengganu 650kW 650k 3k = 217Hybrid Energy - - -

- - -Temenggor, Perak 348 MW 348M 3k = 116 000

Hydroelectric Energy Tenom Pangi, Sabah 66 MW 66M 3k = 22 000Bakun Dam, Sarawak 2400 MW 2400M 3k = 800 0000Bumibiopower Sdn Bhd, Perak 6 MW 6M 3k = 2 000

Biomass Energy Recycle Energy Sdn Bhd, Selangor 9 MW 9M 3k = 3000Naluri Ventures Sdn Bhd, Johor 12 MW 12M 3k = 4 000

(b) State at least 3 applications of solar energy in daily life.

Generates electricity for home (lights, refrigerator)

Solar hot water heaters

Swimming Pools with Solar Heat

Ventilation Using Solar Power

(c) Malaysia aims to reduce carbon emissions from 187 million tons in 2005

to 74.8 million tons in 2020. In your opinion, what are the steps to betaken to achieve this goal in 2020?

According to my point of view, I think the increment in usage of renewable

energy could reduce the percentage of carbon emissions from 187 million tons

to 74.8 million tons by 2020. This can be proven when the transports which

releases ample amount of carbon monoxide, CO to the air can be overcome by

using palm oil as a form of Biomass energy. In fact, each house should fix a

solar panel in the future in order to reduce the carbon emissions as well as to

maintain a cost saving or budget daily life.

Conclusion

As a conclusion of this project, I would like to say that this project helped me in

thinking using various ways. For an instance, the answers obtained by us (my friends

and I who chose the same task Task 1; Solar Energy) is almost the same with

different solutions or methods. From this, I also learnt to strengthen the topics I am

weak at such as logarithms and trigonometric.

Besides that, I have learnt a new lesson while completing my project which

was doing graph using Microsoft Excel efficiently. Using the Microsoft Word, I was

also able to interpret data neatly. In fact, doing graphs using Microsoft Excel is way

smarter than drawing it by hand. Undeniable, it helps us to find certain values

accurately as how the examiner wants.

Finally, I highly appreciate and am thankful to those who helped me to

complete my assignment in a short period of time including my Additional

Mathematics teacherMrs. Tan Gien Pei, parents and also dearest friends.
