Clean Energy Technologies — Prelims Strategy

Prelims Strategy

For Prelims, the strategy for Clean Energy Technologies should focus on meticulous factual recall and conceptual clarity. Firstly, create a concise table for each major technology (Solar, Wind, Hydro, Nuclear, Biomass, Hydrogen, Ocean, Storage) detailing: its core working principle, typical efficiency/capacity factor ranges, key Indian projects/locations (e.

g., Bhadla Solar Park, Muppandal Wind Farm, Puga Valley), associated government missions/policies (e.g., National Solar Mission, Green Hydrogen Mission, National Policy on Biofuels), and any unique features (e.

g., thorium in nuclear, pumped storage hydro as storage). Secondly, pay close attention to numbers and targets: India's renewable energy capacity targets (e.g., 500 GW by 2030), ethanol blending targets (20% by 2025), green hydrogen production targets (5 MMTPA by 2030).

Thirdly, understand the basic definitions and distinctions, such as between clean and renewable energy, or green vs. grey hydrogen. Fourthly, be aware of recent current affairs related to new projects, policy announcements, and international collaborations (e.

g., COP outcomes, new PLI schemes). Finally, practice MCQs that test comparative analysis (e.g., Solar PV vs. CSP, Onshore vs. Offshore Wind) and identify common traps like confusing different types of hydrogen or misattributing policy objectives.

A strong foundation in these areas will ensure high scores in this dynamic section.
