I would like to know whether this center only focus research on hydro-related renewable energy? Is there any focus on any other renewable energy sources, or even in the non-hydro storage systems?
No, as far as I know the center deals with other renewable energy sources as well. They studies wind and solar energy among other types of energy sources. The center is an Interdisciplinary research centre for technical and environmental development of hydropower, wind power, power line rights-of-way and implementation of environment and energy policy among other.
