NON-RENEWABLE
ENERGY SOURCES
WHAT IS NON-RENEWABLE ENERGY
A non-renewable resource (also known
as a finite resource) is a resource that
does not renew itself at a sufficient rate
for sustainable economic extraction in
meaningful human timeframes.
The original organic material, with the
aid of heat and pressure, becomes a
fuel such as oil or gas.
FOSSIL FUELS
Natural resources such
as coal, petroleum (crude oil) and natural
gas take thousands of years to form naturally
and cannot be replaced as fast as they are being
consumed.
Eventually it is considered that fossil-based
resources will become too costly to harvest and
humanity will need to shift its reliance to other
sources of energy.
At present, the main energy source used by
humans is non-renewable fossil fuels.
RADIOACTIVE FUEL
The use of nuclear technology requires
radioactive fuels.
Mined uranium is used to fuel energy-generating
nuclear reactors with fissionable uranium235 which generates heat, that is ultimately used
to power turbines to generate electricity.
Nuclear power provides about 6% of the world's
energy and 13–14% of the world's electricity.
The use of nuclear fuel and the high-level
radioactive waste, the nuclear industry generates,
is highly hazardous to people and wildlife.
