Biofuels — Prelims Strategy
Prelims Strategy
For Prelims, the focus on Biofuels should be primarily factual and policy-oriented. Memorize key government policies like the National Policy on Biofuels 2018 (and its 2022 amendments), including specific targets (e.
g., E20 by 2025-26), permitted feedstocks, and the distinction between 1G, 2G, and 3G biofuels. Understand the objectives and functioning of schemes like the Ethanol Blending Programme (EBP) and SATAT.
Pay close attention to the types of feedstocks used for different biofuel generations (e.g., sugarcane/corn for 1G ethanol, rice straw for 2G ethanol, algae for 3G). Be aware of the primary production processes (e.
g., transesterification for biodiesel, anaerobic digestion for biogas). Current affairs related to new biofuel plants, policy updates, and international collaborations (like the Global Biofuel Alliance) are high-probability questions.
Practice MCQs that test your understanding of these facts, policy provisions, and the differences between various biofuel types and their environmental implications. Vyyuha's advice is to create concise tables for quick recall of generations, feedstocks, and key policy targets.
