In Short : The clean energy revolution is not only about deploying solar panels, wind turbines, and batteries — it is equally about innovation and research. Globally, governments, corporations, and startups are investing billions into research and development (R&D) to improve efficiency, lower costs, and pioneer breakthrough technologies. A key measure of this innovation is the rise in patents, reflecting ownership of new ideas in clean energy. Together, R&D investments and patents are shaping the future competitiveness of nations and industries in the global energy transition.
R&D Investments in Clean Energy
Focus Areas
- Solar Photovoltaics (PV): Higher module efficiency, perovskite cells, bifacial designs.
- Wind Energy: Larger turbines, offshore technologies, lightweight composite materials.
- Energy Storage: Lithium-ion, solid-state, and flow batteries for longer, safer storage.
- Hydrogen: Green hydrogen production, storage, and applications in fuel cells.
- Grid Technologies: Smart grids, demand-response systems, AI-driven forecasting.
Public vs. Private Sector
- Governments: Fund fundamental research and pilot projects through missions and grants.
