This book explores international collaborations that promote ideas and discussions aimed at addressing climate change through research and development. It highlights clean energy innovations from renewable sources, including biomass, hydraulic, hydrogen, photovoltaic, and wind energy. The content includes chapters based on selected papers presented at the 2025 Congress on Research, Development, and Innovation in Renewable Energies (CIDiER 2025). These chapters contain both theoretical and practical research that will enhance the implementation of renewable energy projects among universities, research centers, and private companies in Ecuador and across the broader Latin American community.
