Renewable Energy Adoption and Economic Growth: A State-Level Correlation Analysis of India, 2015-2026

This research examines the relationship between renewable energy adoption and economic growth across Indian states and Union Territories from 2015 to 2026. It looks at differences in renewable energy deployment across states and assesses whether higher population-adjusted renewable energy capacity is associated with stronger economic performance.

Using data from the Ministry of New and Renewable Energy (MNRE), NITI Aayog, and the Census of India, the study compares renewable energy capacity per million population with average real GSDP growth across 33 states and Union Territories. The analysis finds a very weak positive correlation (r = 0.139) that is not statistically significant, indicating that renewable energy capacity alone does not explain differences in state-level economic growth.

The research also examines the geographical and technological differences in India’s renewable energy expansion and draws lessons from international examples including Germany, Denmark, California, and Ireland. It highlights how renewable energy can generate broader economic value when supported by predictable investment frameworks, integrated energy planning, storage and grid infrastructure, employment, and community participation.

The full research provides the methodology, state-level findings, international best practices, and policy recommendations for connecting India’s renewable energy transition with more inclusive, geographically balanced economic development.
