| Primarily derived from plants, bio fuels are fuels that | | | | - Fourth generation: are derived by a method in which |
| are formed when biological matter decomposes. | | | | micro-organisms are raised to work with carbon |
| There are three forms or states of matter that they | | | | dioxide to generate fuel. |

| Comparisons between bio fuels and fossil fuels | | | | Pros: |
| - Bios can be made in a matter of days, unlike fossil | | | | - They provide us with an alternative to fossil fuel. |
| fuels which can take a million years to develop. | | | | - Environmentally friendly, bio fuels help reduce |
| - In terms of pollution, bio fuels are comparatively | | | | carbon emissions. |
| safer. | | | | - They can be cost effective for consumers. |
| - Unlike fossil fuels, bio's are renewable sources of | | | | Cons: |
