The future of electromobility

Renewable energies will constitute an important component in future energy policy. In recent years, use of them has increased constantly, including in traffic. Scientists and researchers have already laid the foundation stones for future usage scenarios - scenarios which will soon form part of the everyday reality of electromobility.

New mobility concepts

Electromobility doesn't simply mean swapping a car equipped with an internal combustion engine for one equipped with an electric motor. Just as important is to respond to people's changing behaviour in terms of mobility – through better traffic planning and the intelligent linking of various means of transport. The way people already combine different means of transport – using public transport, rental bicycles and electric cars in their everyday life, for example, or renting a car once a year to go on holiday in – show that in the future, flexible mobility concepts will be called for.

Distribution grids of the future: Smart Grid

Electromobility constitutes a key building block in achievingGermany's new energy policy aims and can accelerate the integration of renewable energies. Electric vehicles have the potential to serve as decentralised energy storage devices – thus making an important contribution to stabilising the distribution grid. Capable of accumulating energy, they can be charged at times when more renewable energy is available than is being used. Should the flow of energy from renewable sources drop, electric cars can then feed electricity back into the grid, helping to avoid bottlenecks – a technique similar to that currently used in pumped storage power plants. Use of "smart grids" of this type calls for an intelligent charging infrastructure network, such as the one already offered by RWE.
