**Preface to "Sustainable Development Processes for Renewable Energy Technology"**

Currently, the production of energy from traditional fossil sources is beginning to give way to renewable energy technologies. New technological, economic, and environmental requirements raise the question of how to make renewable energy sources a driver of sustainable development for the coming decades. Solar and wind energy, the recycling of synthetic materials, and new methods for their utilization can not only significantly reduce the burden on the environment, but also give a new impetus to the development of modern industry and help find a new balance between the needs of people and the capabilities of nature.

One of the tools for achieving these goals is a multidisciplinary approach to solving key problems and an analogous approach to the related scientific research process.
