We are delighted to welcome all researchers, industry professionals, and thought leaders in the energy sector to the 4th International Summit on Non-Renewable and Renewable Energy (ISNRE2026), which will be held in Venice, Italy on August 24–25, 2026. Following the successful completion of our previous editions- ISNRE2023 in UK, ISNRE2024 in Spain and ISNRE2025 in Germany, we are thrilled to announce that ISNRE2026 is set to be even more impactful. Building on the strong foundation of these past summits, ISNRE2026 will continue to serve as a premier global platform to advance discussions on the transition from non-renewable to renewable energy sources, the integration of sustainable technologies, and the development of innovative strategies to address the world’s evolving energy challenges.
