| Biofuels |
|
N Collins,
Catalyst:
GCSE Science Review,
2006, Vol 17, Issue 1,
pages 14-16.
|
| Summary:
Burning fossil fuels releases extra carbon dioxide into the atmosphere, which contributes to global warming. However, burning renewable biofuels is part of the normal carbon cycle and does not contribute to an increase in atmospheric carbon dioxide. Examine the ways in which the energy stored in biofuels can be released. |
