History

World Sustainable Energy Day (WSED) was first held in 1992 by the Austrian Energy Agency (AEA). The event focused on the role of renewable energy sources in the transition to a sustainable energy system and included presentations on wind power, solar energy, and biomass.

Theme

The theme for WSED varies each year, but it typically focuses on a particular aspect of sustainable energy. This year’s theme is "Energy transition = Energy security!". WSED 2023’s theme will focus on how transitioning to sustainable energy can help make countries energy independent. The theme comes in the backdrop of the last year’s European energy crisis that began due to rising tensions with Russia.

WSED features a range of events and activities, including conferences, workshops, and site visits to showcase sustainable energy technologies in action. The event also includes an international trade show that brings together companies and organisations from around the world to showcase their sustainable energy products and services.
