Prelims Strategy

Focus on memorizing specific data points: PAT scheme covers 8 sectors, EESL distributed 370 million LEDs, ECBC applies to buildings with 100+ kW connected load, designated consumers threshold of 120 toe annually.

Master institutional roles - BEE for policy/standards, EESL for implementation/procurement, state agencies for local programs. Understand constitutional basis (Article 48A, 51A(g), concurrent list) and legal framework (Energy Conservation Act 2001, 2010 amendment).

Practice elimination techniques by identifying common traps: confusing BEE and EESL roles, mixing up sectoral coverage numbers, incorrect threshold values. Create mental maps linking schemes to implementing agencies, sectors to specific programs, and policies to outcomes.

Use acronyms for recall: PAT-STEEL (Power, Aluminum, Textiles - Steel, Thermal, Fertilizer, Cement, Paper) for sectoral coverage. Focus on recent developments: updated NDCs, PLI schemes, Green Hydrogen Mission integration.

Practice questions combining efficiency with other topics like renewable energy, climate policy, and industrial development.
