Study Notes
Fossil Fuels and Their Consequences
- Burning fossil fuels leads to air pollution and global warming.
- Conservation of crude oil is crucial to avoid a shortage, impacting the availability of chemicals.
- Depletion of crude oil would significantly increase the production costs of plastics, drugs, and other essential chemicals.
Alternative Fuels - Biofuels
- Biofuels are renewable energy sources derived from plants, unlike finite fossil fuels.
- Palm oil is being explored in certain countries as a viable alternative fuel, requiring minor engine adjustments for diesel trucks.
- Ethanol, predominantly produced from sugarcane in Brazil, serves as an effective vehicle fuel.
Ethanol and Gasohol
- Ethanol mixed with petrol is known as gasohol, commonly used in Australia and the USA.
- Ethanol production employs the fermentation of sugars from plants, primarily sugarcane.
Environmental Sustainability of Biofuels
- Biofuels present a renewable alternative to natural gas and crude oil.
- When compared to fossil fuels, biofuels can reduce carbon dioxide emissions, making them more environmentally sustainable.
- Ethanol sourced from sugarcane is recognized as a biofuel and highlights the potential of using renewable resources.
Limitations of Biofuels
- The scalability of plant-based fuel production may not meet industrial energy requirements or electricity generation.
- Cultivating energy crops may compete for land better suited for food production, raising food security concerns.
- The assertion "Biofuels are not the fuels of the poor; they are the foods of the poor" emphasizes the socio-economic implications of biofuel usage.
