Question
Describe how bio-fuels are used for transport and discuss one advantage and one disadvantage of using them.
Answer
Bio-fuels are used in transport primarily as an alternative to petrol and diesel, often blended with traditional fuels to reduce emissions. One advantage of bio-fuels is that they can be produced from renewable resources, which can help reduce reliance on fossil fuels. However, a disadvantage is that their production can compete with food supply, potentially leading to higher food prices.
Explanation
This question assesses the student's ability to describe the application of bio-fuels in transport while also evaluating their understanding of the associated advantages and disadvantages. It encourages critical thinking about the implications of energy resource choices.
Common mistake
Confusing Energy Resource Uses
Students often confuse the uses of different energy resources for transport, electricity generation, and heating, leading to incorrect comparisons.
To fix this, create a table that clearly outlines the specific uses of each energy resource in transport, electricity generation, and heating, and refer to it when making comparisons.
