The German Aerospace Center (DLR) in Stuttgart consists of six research institutes conducting research into the areas of aeronautics, space, energy, transport and security. It currently employs more than 600 people. Today's DLR site goes back to the Research Institute of Jet Propulsion Physics, which was founded at the Stuttgart Airport in 1954.

Switzerland will be able to obtain 98 percent of its electricity needs from renewable energy sources by the year 2050, while the corresponding figure for Poland reaches nearly 90 percent. In the long term, a sustainable energy supply is possible in both countries. These figures are shown by energy scenarios that DLR researchers have prepared on behalf of Greenpeace.
The range and performance of electric vehicles depends directly on the batteries used. Lithium-ion batteries are currently considered very promising for use in alternative vehicle propulsion systems due to their high energy density and low capacity loss when frequently, but incompletely, charged and discharged.
How many electric cars will be using Germany's roads in 2020? None of us have a crystal ball and this will depend on a wide variety of factors.
