Our Earth, Our Home

Energy

Why need What the examples

Where to findWhat are the problems

What is energy ?

Energy is power.Example:• Walking• Running• Talking

Why do we need energy?Because we can do anything.Example :•Industry•Transportation•Home appliances•Cooking•Electricity requirement

Where do we find the energy ?

•Fossil fuel from earth•Coal from mine•Natural gas

What are the types of energy that we use now?The types of energy are : Nuclear Energy Fossil fuel Natural gasses Coal Solar power Water Energy Wind Energy

The problems we face in using energy now and future ?

Prod

Time

Yes, we have.Example: •Decreasing fossil fuel

•Getting expensive•Non Renewable resources

•Cause pollution and emission•Green house effect •Global warming

What is eco-energy?

Eco-energy is the alternative sources which is environmentally friendly. The reasons are:

Cheaper Unlimited Sources Easy to find and to produce Short time

Why eco-energy is the best solution for our world ?

Prod

Time

•Increasing•Eco environmentally friendly•Renewable resources•Easy to access•Cheap and low technology content

How can we get eco-energy ?

Plants Jathropa Curcas Coconut Olive Soy Bean Corn Sweet potatoes Switchgrass

Animal Meat Fat

What kind of eco-energy do we develop in Indonesia?

Gas fuel Jathropa’s oil Bio diesel

Why must Biodiesel from Jarak PagarJatropha Curcas L.- Jarak Pagar

The fruit The Seeds Tree

High oil content 30 – 50 % compared with others It can grow in critical land. Can grow 30 until 35 years The seed can be useful Low cost for harvesting The oil can be used for all type engine Soap and glicerol oil are other commercial products The waste contain N,P & K higher than other organic fertilizer Can also be used for animal food after detoxification process

Because

ECO ENERGY HELPS THE WORLD CLEANER

Grow in crisis landmark, start

producing in the sixth month until 50 years

25 million crisis landmark

Jathropa’s fruit.

Jathropa’s seed production until 10 ton

Allah is He Who has created the heavens and the earth and sends down water (rain) from the sky, and thereby brought forth fruits as provision for you; and He has made the ships to be of service to you, that they may sail through the sea by his command; and He has made rivers (also) to be of service to you.

Nuclear Energy

Believed to be the cleanest and most efficient way to create electricity

Harmful radioactive wastes takes thousands of years to decay.

Nuclear Energy

Problems of storing and re-processing nuclear wastes exist in advanced countries.

Generated through burning oils, coals, or natural gases to drive turbines

Fire Energy

Defects:1. Higher building cost 2. Noise pollution 3. Potential danger

Advantages: 1. Fast start-up

process 2. Simple equipment 3. Convenience in

adding fuels 4. Low requirement

on cooling water 5. High thermal

efficiency

Fire Energy

Solar Energy

Created through solar cells from the sun’s light and heat

Restrictions:1.Time of day light 2.Seasonal

changes3.Terrain

conditions

Solar Energy

Merits: 1. No pollution 2. Obtained as long

as there is sunlight

3. No harm to the environment

→ The solar energy created from the deserts can solve the global energy crisis.

Water Energy

Created from flowing water used to make electricity.

Defects:1.High building

cost of dams2.Potential

damage to the environment

Water Energy

Advantages:

1. No air pollution

2. Low upkeep costs

Wind Energy

Generated through turning windmill sails

Defect: Unstable energy sources

Wind Energy

Advantages: 1. No fuel

problems 2. No pollutants

such as radiation or CO2

3. No energy crisis of over consumption

4. Lowest building cost
