UPSC Previous Year Question | Prelims GS | 2017

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 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

Answer

Correct Answer

2 and 3 only

Explanation

Algae biofuel production is possible on land (e.g., ponds, bioreactors), not restricted to seas only, so statement 1 is wrong. High-tech expertise requirements (statement 2) and large-scale facility concerns (statement 3) are genuine limitations for developing countries.
