- Biofuels
- Ethanol
- Fermentation
- Oil substitute from **** seed oil.
- Biogas (methane) is used on a small scale to power generators
- Bio-ethanol is an alcohol mixed with petrol
- Any fuel from a biological origin
- Can be as polluting as petroleum-based fuels due to the energy used in farming and processing the crops
- Brazil leads the world production of ethanol
- Makes 16 million litres per year from sugar cane
- 60% of new cars can run on a fuel mix containing 80% ethanol
- Reduce in biodiversity as forests are cleared for monocultures
- Palm oil plantations in Asian countries
- Food prices may go up as more land is used to grow crops for fuel
- Technical problems limit production
- Only specific parts of the plants can be used
- The tough cellulose in the plant cell walls has to be pre-treated before fermentation
- Hoped that second generation of bio fuels will process the cellulose found in many plants making wastage less and production more effiecient
- Ethanol
