Coal is a solid non-renewable energy source composed of carbon, nitrogen, oxygen, hydrogen, and sulfur, with anthracite being the most energy-rich type. Natural gas, primarily methane (CH4), is a cleaner and less polluting alternative used for power generation and transportation. Petroleum, formed from ancient sea organisms, is refined to produce various fuels like petrol and diesel.

NON-RENEWABLE SOURCE OF ENERGY

4. coal is the only one still in a solid state. It appears as chunks of
midnight black rock, which are harvested from the Earth by
workers in mining operations. Coal is composed of five different
elements: carbon, nitrogen, oxygen, hydrogen, and sulfur.
The highest in energy content is anthracite coal, which is harder and has a higher
distribution of carbon than the other varieties. The other two types of coal – lignite
and bituminous – aren’t quite as energy-rich, but still have their uses. Lignite is high
in oxygen and hydrogen instead of carbon, while bituminous occupies a sort of happy
medium between the two extremes. Coal is a dynamic fossil fuel in terms of how it is
used. Depending on the breakdown of coal uses that you look at, you might see the
top uses listed as a generic “electricity generation” any case, coal today is used for
everything from producing steel and cement to keeping the lights on in homes and
businesses

5. Natural gas is a mixture of hydrocarbons
with small molecules. These molecules
are made of atoms of carbon and
hydrogen. For example, natural gas used
in the home is mainly CH 4.
Natural gas is stored under high pressure as compressed
natural gas (CNG). CNG is used for power generation. it is now
being used as a fuel for transport vehicles because it is less
polluting. It is a cleaner fuel. The great advantage of CNG is that it
can be used directly for burning in home and factories where it can
be supplied through pipes.

6. petrol and diesel are obtained from a natural
resource called petroleum. Petroleum was
formed from organisms lived in sea. As these
organisms died, their bodies settled at the
bottom of the sea and got covered with layers
of sand and clay. Over millions of years,
absence of air, high pressure and high
temperature transformed the dead organisms
into petroleum and natural gas. Petroleum is a
dark oily liquid it has an unpleasant smell. It is
a mixture of various constituents such as
petroleum gas, petrol, diesel , lubricating oil,
paraffin wax , etc… the process of separating
various constituents of petroleum is known as
refining. It is carried out in the petroleum
refinery.
