Andy from GENI gives a short presentation about energy storage technologies and how renewable energies are becoming more and more of an important aspect of today's energy grid.

Some 32 social scientists and researchers from around the world, including a Senior Sustainability Scholar at Arizona State University, have concluded that fundamental reforms of global environmental governance are needed to avoid dangerous changes in the Earth system.

The 22-member Panel, established by the Secretary-General in August 2010 to formulate a new blueprint for sustainable development and low-carbon prosperity, was co-chaired by Finnish President Tarja Halonen and South African President Jacob Zuma. The Panel's final report, "Resilient People, Resilient Planet: A Future Worth Choosing", contains 56 recommendations to put sustainable development into practice and to mainstream it into economic policy as quickly as possible.
