It is possible to produce algae-based biofuels, but what is/are the likely limitation(s) of developing countries in promoting this industry?

1. Production of algae-based biofuels is possible in seas only and not on continents.
2. Setting up and engineering the algae-based biofuel production requires a high level of expertise/technology until the construction is completed.
3. Economically viable production necessitates the setting up of large-scale facilities which may raise ecological and social concerns.

Select the correct answer using the code given below:

1. 1 and 2 only
2. 2 and 3 only
3. 3 only
4. 1, 2 and 3

Explanation

Statement 1 is incorrect

• Algae cultivation does not need to be restricted to seas or marine environments; it can be grown in various water environments, including ponds, lakes, or artificial tanks on land.

Statement 2 is correct

• Setting up algae-based biofuel production requires sophisticated engineering and advanced technology, especially during the initial stages of construction. Expertise is essential for designing and constructing facilities that can efficiently cultivate and harvest algae for biofuel.

Statement 3 is correct

• Large algae farms can use significant amounts of water, energy, and land resources, potentially leading to environmental issues such as water scarcity, habitat disruption, or changes in land use.

Answer: (b) 2 and 3 only; Difficulty Level: Easy
