Renewable energy sources
L.O to be able to explain and understand the five main types of renewable energy sources and to compare them.
Thinking Question – What does renewable energy mean?
ALL – Should be able to understand and recall the five main types of renewable energy sources.
MOST – Should be able to suggest advantages and disadvantages of the five main types of renewable energy.
SOME – Should be able to compare the five main types of renewable energy and evaluate ideas.

Renewable Energy:
Energy from a source that can be reused over again and does not add to the effects of global warming.(Please write this in your books)Slide3
What types of renewableEnergy do these pictures
Represent?
Discuss in your groups
E.G Water
Wind
Sunlight/Solar
Geothermal
Biomass
challengeSlide4
biomass
Wood, trimmings, non recyclable organics
decompose and are
combusted. The sun’s energy is trapped in
biofuel for a long time. This helps create electricity in a
power plant.

Please write a brief summary in your books.
It naturally decomposes.
Sun’s power is trapped in biofuel for a long time
Takes in Carbon Dioxide from the air.
Destroys habitats
Hard to transportSlide5
geothermal
Hot rock
can be used to generat
e electricity.Simply water is sent down to the hot rock bed, causing hot
steam to rise up, meaning
generators can turn…producing electricity!

Advantages?/
disadvantages?
Easy to Extract
Not weather dependant
Not all places have geothermal energy.

Please write a brief summary in your books.Slide6
waterWater can be used
to create energy in many different ways. The main two are either simply allowing water to pass through a
generator or by using a
wave machine.
Sea water generator

Advantages?/
disadvantages?
Free and reliable source
Renewable!
Villages and habitats can be destroyed and damaged by unnatural currents
1000 times heavier than air.
Please write a brief summary in your books.Slide7
Wind
Wind can be used to generate electricity via wind turbines
. When the wind blows, the propellers spin, turning the
generator which is generating electricity. They can be placed both on land or in the sea.
Think:pair

Advantages?/
disadvantages?
Generates lots of energy
Renewable!
Can be placed on both land and sea
Turbines are expensive
Weather dependant
Can’t be placed everywhere (not enough wind)
Please write a brief summary in your books.Slide8
solarSolar
energy takes in
light and heat from the sun. the
photodiode (or photovoltaic) inside
solar panels converts the sunlight into electricity (photodiodes generate considerable amounts of energy!) the most common example of this is a
solar panel, seen commonly on roofs, in a
solar farm or in small things like calculators! They are becoming increasingly popular.

Advantages?/
disadvantages?
No moving parts
Can be used to power homes too
Works anywhere with sunlight
Provide considerable amounts of energy
Can be expensive to manufacture and buy.
Needs frequent sunlight
Please write a brief summary in your books.Slide9
ALL – Should be able to understand and recall the five main types of renewable energy sources.MOST – Should be able to suggest
advantages and disadvantages of the five main types of renewable energy.
SOME – Should be able to compare the five main types of renewable energy and evaluate ideas.

Which type of renewable Energy source do you think is the
best?
Using keywords and your notes, explain which renewable energy source you believe is the best. Try to compare the five different renewable energy sources too (show their differences and similarities).
Keywords:
Wind, Water, Solar, Geothermal, Biomass, Renewable, Power Plant, Generator
Try to evaluate your ideas using advantages and disadvantages if you haven't already.E.G Although solar panels can generate lots of electricity, they will only perform when a good amount of sunlight is produced… The Water source however can perform when…

Peer assessment
Criteria:
*Have they used keywords?
*Have they compared the five sources?*Have they explained in detail?
*Have they evaluated their ideas?*Did they show a good understanding?
