उत्तर १
| Sr. No. | 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. |
उत्तर २
| Sr. No. | 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 |
