Some countries produce more sustainable energy than they need. New technologies help distribute surplus power efficiently.

Sun, wind and water can supply sufficient energy to cover the worldwide demand. An efficient global power grid is an important key of innovation to achieving this goal.

A large high-voltage battery like the one in the Audi e-tron stores up to 95 kWh of energy. Theoretically, this is enough for operating various appliances around the clock

In his thriller “Blackout,” Marc Elsberg describes the collapse of civilization within just a few days due to catastrophic failure of the power grids. How vulnerable are modern societies?

The development of humanity is inseparably tied to the amount of energy we’re able to generate and consume. A brief history of human energy consumption in five chapters.
