Difference between conservational and non-conservational sources of energy
Answers
Answer:
Conventional Sources
Conventional sources of energy (e.g. coal, petroleum and natural gas) are non-renewable sources of energy.
They have been in use since a long time. For example, firewood and coal have been in use since a long time.
Most of these energy sources (e.g. coal and firewood) cause pollution when used.
They are common and widely used sources (e.g. thermal power).
Non-conventional Sources
Non-conventional sources of energy (e.g. solar and wind energy) are renewable sources of energy.
These sources have recently developed and are still developing. For example, the technology of producing electricity from solar panels has recently developed.
They do not cause any pollution (e.g. solar energy, geothermal energy etc.)
They are comparatively new sources of energy and hence are not widely used. For example, solar panels and wind mills are not widely used.
