This document discusses renewable and non-renewable energy sources and their impact on climate change. It classifies various energy sources as renewable or non-renewable and notes that while non-renewable sources like coal and oil are limited and increase pollution, renewable sources can be replenished from natural sources but devices to collect and store this energy can impact the environment and be costly. It questions whether renewable energy can meet global energy demands and compares energy reserves of non-renewable sources to usage.

1. RENEWABLE AND
NON-RENEWABLE
SOURCES
Are we facing an energy crisis?

2. LEARNING OUTCOMES
 Compare the use of non-renewable and
renewable energy sources and their
impact on global climate change

3. CLASSIFY THE FOLLOWING:
 Biomass
 Coal
 Hydroelectricity
 Natural Gas
 Nuclear energy (fission)
 Oil
 Solar energy
 Wind energy

4. NON-RENEWABLE SOURCES
 Cannot be replenished
 Limited and will be used up after some
time
 Increase air pollution during consumption.
Gases and particulate matter emitted
into the atmosphere not only reduce air
quality but also cause harm to humans

5. NON-RENEWABLE SOURCES
 Do you think that these resources can
last us for a long time?
 How much energy reserves do we have
left?

6. RENEWABLE SOURCES
 Renewable energy sources can be
replenished continually as they are
abundantly found in nature
 All of them are non-polluting but the
devices used to collect the energy may
impact the environment adversely
 They are free but producing storage
equipment or converting them into
another form of energy may be costly

7. RENEWABLE SOURCES
 Do you think it is feasible to rely on
renewable energy sources to meet the
Earth’s energy demands?
