Four points of difference between conventional and non-conventional sources of energy are
Conventional Sources |
Non-conventional Sources |
Conventional sources of energy (e.g. coal, petroleum and natural gas) are non-renewable sources of energy. |
Non-conventional sources of energy (e.g. solar and wind energy) are 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. |
These sources have recently developed and are still developing. For example, the technology of producing electricity from solar panels has recently developed. |
Most of these energy sources (e.g. coal and firewood) cause pollution when used. |
They do not cause any pollution (e.g. solar energy, geothermal energy etc.) |
They are common and widely used sources (e.g. thermal power). |
They are comparatively new sources of energy and hence are not widely used. For example, solar panels and wind mills are not widely used. |
