GCSE Geography · key term
A fuel made from biological material, such as crops.
Used by AQA and Edexcel
Specification 3.2.3.4 · Paper 2
Fuel made from biological material, such as crops, which can be used to provide energy.
Revise: Global Energy Distribution, Demand and InsecurityIf farmland is used to grow biofuel crops, less land may be available for food crops, putting upward pressure on food prices. Farmers may respond through more intensive production, which itself requires energy and can add to demand.
Specification 3.2 · Paper 1
Do not assume a renewable resource is always used sustainably: trees can be felled faster than they regrow, and biofuel crops can compete with food crops for land.
For this Edexcel course, classify nuclear and biofuels as recyclable. Nuclear fuel is still finite; recyclable does not mean inexhaustible.

Fuel made from recently living biological material, such as bioethanol produced from sugar cane.
Crops such as sugar cane can be fermented to produce bioethanol, a biofuel.
Paper 3
Revise: Threats to rainforestsBiofuel demand can encourage agricultural expansion. For example, growing sugar cane for fuel requires land; clearing rainforest to establish these crops turns energy demand into a cause of deforestation. In Indonesia, oil-palm plantations producing biofuels for export have contributed to clearance on Borneo and Sumatra.
Fuel made from biological material, such as crops or plant waste.
Fuel made from biological material, including crops and organic waste.
