This document discusses different types of energy resources. It categorizes energy resources as renewable and non-renewable, and provides examples of each. Non-renewable resources like coal, oil, and natural gas were formed over millions of years from decayed plant and animal remains. These are finite and will eventually run out. Renewable resources like wind, solar, and hydropower can be replenished and will not run out. The document also discusses the formation and uses of key fossil fuels like coal and petroleum, as well as nuclear energy from uranium.

2. • Energy resources are the main sources of energy
from which the energy can be extracted and
utilized for mankind.
• All forms of energy are stored in different ways, in
the energy sources we use every day.
• Energy is a key input in economic growth.
• The growth of a nation largely depends on the
availability of energy resources.

3. The energy resources can be classified on the basis
of:
Usability of energy resources,
Traditional usage of energy resources,
Long-term availability of energy resources,
Commercial application of energy resources, and
Origin of energy resources.

4. Renewable Nonrenewable

5. Non-renewable energy sources
Oil, coal and natural gas are examples of fossil fuels.
They were formed from biological deposits over the
course of millions of years.
There is a finite amount of these materials on the Earth
so they will run out eventually.
Once they are used up they cannot be regenerated and
used again.
Oil Coal Natural gas

6. Renewable energy sources
These will not run out
because they can easily be
regenerated.
Examples are wind power,
solar power, tidal power and
biomass.

7. Fuels may be solid, liquid or gaseous
Fossil fuels may be coal, petroleum-
crude derived or natural gas.

8. Fuels are substances which, when
heated, undergo chemical reaction
with an oxidizer, typically oxygen, to
liberate heat.
Commercially important fuels contain
carbon and hydrogen and their
compounds, which provide heating
value

9. These fuels were dug out of the ground. They had taken millions
of years to make and so are called FOSSIL FUELS and are
NON-RENEWABLE.
COAL
Made from the remains of plants which
died millions of years ago

10.  Coal is a solid fossil fuel that is formed in
several stages as the buried remains of land
plants that lived 300-400 million years ago.

15.  When isotopes of uranium and plutonium
undergo controlled nuclear fission, the
resulting heat produces steam that spins
turbines to generate electricity.
 The uranium oxide consists of about 97%
nonfissionable uranium-238 and 3% fissionable
uranium-235.
 The concentration of uranium-235 is increased
through an enrichment process.
