Renewables Working Together: Renewable Energy Systems and Synergies

The International Solar Energy Society webinar:

Renewables Working Together: Renewable Energy Systems and Synergies

Friday 30 October 2015 at 15:00 CET

Achieving the goal of a world supplied by 100% renewable energy will require a clear understanding of how different renewable energy technologies can work together to provide reliable energy systems. This webinar brought together five renewable energy technology organisations, representing solar, wind, geothermal, hydro, and bioenergy, to provide case studies and best practices of cities, regions, and countries where various high-penetration combinations of renewable energy technologies are working together.

Five expert panelist speakers presented during the webinar:
