Renewable energy sources like biomass, wind, water and geothermal are always available and will not be depleted over time. Non-renewable sources such as fossil fuels and nuclear will eventually be used up if not replenished. Fossil fuels are burnt to produce steam that turns turbines and generators to produce electricity, while nuclear energy harnesses heat from splitting atoms for the same process. Biomass and geothermal also produce heat energy, and wind and hydroelectric use the motion of their respective resources - wind and water - to power generators.

1. Source Of
Energy

2. Type of Energy Source
• Renewable; Always available and will not
be used up
• Non-Renewable; Will be used up one day
if fail to replenish it

3. Source of Energy
• Fossil fuel are animal and plant’s long
dead remain
• Nuclear are energy in the nucleus of
certain metal
• Biomass are wood, rotting
animal, plant, matter, waste etc.
• Geothermal are natural heat energy within
the Earth
• Wind

4. Fossil fuels
• Coal, natural gas are burnt
• Crude oil must be separated by fractional
distillation into different type of fuel
• In power station, fuel is burnt and the heat
produced heat water up to steam. The steam
rotates the turbine blade and the kinetic
energy of the rotating blades are changed
into electrical energy by generators
• Produce large amount of energy
• Eveready
• Non-renewable
• Cause air pollution as it give out harmful gas

5. Nuclear Energy
• Energy released during the splitting of an atom or
combine of atom
• A cooling system removes the heat released
during the splitting of an atom
• The hot cooling system will be used as a heat
source for a boiler
• The pressured steam from that boiler will power
the steam turbine driven generators to produce
electricity
• It doesn’t pollute the environment
• It gives out lots of energy
• Eveready

6. Biomass
• The decay of organic waste produce gas
used for heating and cooking
• Renewable
• More Expensive to produce

7. Geothermal
• Water is pumped to the Earth to change it
into steam
• The steam collected power turbines which
turn generators to produce electricity
• Natural occurring
• Only available in places where the heat of
the Earth comes near the surface

8. Wind
• Wind turn windmill to generate the windmill
which produce electricity
• Renewable
• Only available when there is wind
• Not efficient and dependable

9. Water
• Water is stored in dam/reservoir to power
turbine blade . The moving blade is
changed to electrical energy by generators
• Renewable
• Construction of dam have impact on the
environment
• Require great difference in tidal level

10. Solar
• Solar panel absorb light to produce
electricity
• Non-polluting
• Not available when it is cloudy or at night

11. Energy storage
• Container like shed store coal
• Dams store large amount of water
• Electric storage cell store electric

12. Summary
Renewable energy like biomass, wind and
water is always available and will not be used
up.Non-renewable energy like fossil fuel and
nuclear will be used up one day if not
replenished. Fossil fuel boil water to generate
turbine. A cooling system that cool the split atom
will be used as a boiler which power the steam
turbine to produce electricity. Biomass produce
gas used for cooking and heating. Water boiled
in Earth to turn generators to produce electricity.
Wind generate windmill to produce electricity.
