• fuels as they are formed from fossils.

CONVENTIONAL SOURCES

• the sources that have been in common use for a long time are called conventional sources of
• energy..
• EG. are firewood, coal, petroleum
• and natural gas.

eg. of conventional sources

• FIREWOOD
• Firewood is primarily used for cooking and heating.
• it is not a
• very convenient and eco-friendly source of energy.
• Collecting firewood
• and cooking with it is time consuming and also burning firewood releases
• carbon monoxide in the air. This results in air pollution and higher

• The major petroleum
• producing countries in the world are Iran, Iraq, Saudi Arabia and Qatar.
• NATURAL GAS
• it is traditionally used as a
• source of energy. It is found with petroleum deposits and is released
• when the crude oil is brought to the surface.
• HYDEL POWER
• Electricity is generated from the energy of flowing water & The
• energy derived from flowing water is called hydro power.
• The electricity
• generated from hydro power is called hydroelectricity.
• Norway was the
• first country in the world to develop hydroelectricity.
• The leading
• producers of hydro power in the world are Paraguay, Norway, Brazil, and
