|
Conventional sources of Energy have been used since a long time |
Non-Conventional sources of Energy are recently discovered sources of energy |
|
They are common and widely used sources |
They are relatively new and hence are not widely used. Example - Solar cells are still not widely used |
|
Most of these sources cause pollution when used |
Most of these sources do not cause pollution when used |
|
