Lesson 8. Renewable Energy and Sustainable Technologies
Moving beyond traditional science, this topic is central to India’s development and environmental commitments. It requires understanding the science, potential, and challenges of various renewable sources: Solar (photovoltaic vs. thermal, grid-scale and rooftop, National Solar Mission), Wind (onshore and offshore potential), Hydropower (small vs. large, environmental concerns), Biomass & Biofuels (generations of biofuels, ethanol blending program, Gobar-Dhan scheme), and emerging areas like Green Hydrogen (production via electrolysis, National Green Hydrogen Mission). Related concepts include energy storage (battery technologies, pumped storage), smart grids, and energy efficiency (standards and labeling). This topic directly links to climate change mitigation, air pollution reduction, and energy security.
Additional Resources: The Ministry of New and Renewable Energy (MNRE) website is the primary source for schemes, targets, and policy documents. International Energy Agency (IEA) reports and IRENA (International Renewable Energy Agency) publications offer a global perspective and data. NITI Aayog reports on energy transitions are also highly relevant for the Indian context.
