2. distinguish between the conventional sources of energy derived from coal and water. *
Answers
Answer:
Always surround yourself with positive energy’. You must have heard this phrase quite a lot; what is this energy we’re talking about? Do things have energy in them? And are these things conventional sources of energy? But, before that what are conventional sources of energy? How do we obtain this energy? Since all living beings use energy for various vital activities inside as well as outside their body. So, let us study about various conventional sources of energy below.
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.
