The document discusses different non-renewable energy sources including coal, petroleum, natural gas, and nuclear energy. It explains how each source is formed in nature and how it can be converted into electricity through various processes. Key methods mentioned include burning the sources to create steam that spins turbines and generators, as well as using uranium in nuclear power plants to produce heat. The document also briefly introduces steam engines, internal combustion engines, steam turbines, and gas engines as machines that can transform thermal energy from these sources into mechanical energy.

2. Non-renewable energy sources
Coal
Composed of carbon and hydrocarbons
Made of remains of ancient trees and plants
How is it converted into electricity?

3. Non-renewable energy sources
Petroleum
Composed of hydrocarbons
organic compounds
Find in underground areas (reservoirs)
How is it converted into electricity?
1. Oil is burnt in turbines in power stations extreme heat
high-pressure steam.
2. This steam spin a turbine very fast by pushing against metal
blades
3. The blades turn a generator produces electricity.

4. Non-renewable energy sources
Natural Gas
Colorless, shapeless and odorless
Clean burning
23.8% of the world’s energy
Comes in two main types:
Found in permeable sandstone resevoirs
Found in coal deposits or shale rock formations
How is it converted into electricity?
Natural Gas is burned pressirized gas spins the blades of
turbines metal coils and magnets in a generator electric
current.

5. Non-renwable energy sources
Nuclear energy
is energy in the nucleus (core) of
an atom
nuclear power plants use
uranium as fuel
in a form of: heavy metal,
naturally occurring in most rocks, soil,
and even in the ocean
it provides the main source of
heat inside the earth

6. Transformation of thermal energy into mechanical
energy
Machines
Steam engine
Using steam power to perform
mechanical work through the
agency of heat.
Internal Combustion Engine
engine where the combustion of a fuel
occurs with an oxidizer (usually air) in a
combustion chamber that is an integral
PART of the working fluid flow circuit.

7. Steam turbine
is powered by the energy in
hot, gaseous steam which spin
blades
Gas Engine
internal combustion engine which runs on
a gas fuel
