Question

Explain the difference between conventional and non-conventional sources of energy.

State two differences between conventional and non-conventional sources of energy.

Answer 1

	Conventional sources of energy	Non-conventional sources of energy
i)	Conventional sources of energy are the sources that are commonly in use since a long time.	Non-conventional sources of energy refer to the sources that are identified a few decades ago.
ii)	Conventional sources of energy are limited and exhaustible.	Non-conventional sources of energy are abundant and inexhaustible.
iii)	They cause pollution.	They cause little or no pollution.
iv)	Fuels produced from conventional sources are comparatively expensive.	Fuels produced from non-conventional sources are comparatively cheaper.
v)	Conventional sources do not produce green energy.	Non-conventional sources produce green energy.
vi)	They are primarily used for industrial and commercial purposes.	They are mainly used for domestic purposes.
vii)	Example: fossil fuels such as coal, natural gas, etc.	Example: wind energy, solar energy, etc.

Answer 2

Conventional sources of energy	Non-Conventional sources of energy
(i) These are those sources which have been in use from ages.	These sources have generally been identified in the recent past.
(ii) These are non-renewable sources of energy.	These are renewable sources of energy.
(iii) These will last long, just for 100-200 years.	These are going to last forever.
(iv) These cause air and water pollution.	These do not cause any pollution.
(v) These are very expensive to maintain, store, and transmit, e.g., coal, mineral oil, natural gas, atomic power, and water.	These are less expensive or cheap due to local used easy to be maintained e.g. solar energy, tidal energy, wind energy, geothermal energy
