2.

*All resources in nature divide into
renewable and non-renewable.
*Renewable resources can be
replenished through natural processes
or be replaced through biological
processes. But even renewable
resources are not unlimited.
*Non-renewable resources cannot be
replaced

4. Energy sources

Renewable :
Non-renewable:
• Solar energy
• Wind energy
• Tidal energy
• Hydropower
• Biomass
• Geothermal energy
• Coal
• Crude oil and
petroleum
• Natural gas
• Nuclear power

5. Non-renewable energy sources

* Fossil fuels have a high
percentage of carbon. That
is why burning fuels we
also release carbon
dioxide, which contributes
to global warming.
* Nuclear power does not
Nuclear power does not
pollute the air. However,
there are many risks that a
small mistake at power
plants can cause a
catastrophe.

6.

* Fossil fuels and
nuclear power are
quite dangerous for
our environment.
* Our global use of
energy increases every
year.
* The challenging
question is how we
can satisfy our
demands.
* One way is using
renewable energies.
They are more
distributed and have
minimal amount of
drawbacks.

7. Water

* One of the cheapest alternative energy source is
water
* To get electricity from water people build
hydropower plants
* China, Canada, Brazil, the United States, and
Russia are the largest producers of hydropower.

Types of Hydropower Plants

10. Advantages of Hydropower

* It’s a clean fuel source and doesn’t pollute the air
* Hydroelectric power is a domestic source of energy,
so each state can produce its own energy
* The energy generated through hydropower relies on
the water cycle. It is a renewable power source,
more reliable and affordable than fossil fuels
* Some hydropower facilities can quickly go from zero
power to maximum output. They provide essential
back-up power during electricity disruptions
