Abstract for: Understanding the dynamics of sustainable mobility and energy solutions and economic implications for their competitiveness

Electric vehicles, photovoltaic systems and battery storages are promising components of sustainable mobility and energy solutions for private households. A fast marked diffusion of these technologies requires their cost competitiveness against conventional technologies such as combustion vehicles and fossil-fired power plants. However, the economic benefit depends on the customer needs for mobility and energy, so a differentiated consideration of the mass market is needed to identify the most suitable target customers. Moreover, the cost advantage is affected by volatile factors such as electricity and fuel prices. Therefore, the cost competitiveness has to be checked regularly. Finally, a prudent technical design is essential if the economic benefits for the customers are to be fully leveraged. Based on System Dynamics, the technological synergies and the resulting mobility and energy costs can be investigated. By parameter variations, the model user can easily modify the customer needs and the technical design and thus gain an immediate feedback concerning the energy exchanged with the power grid. Exemplary simulation runs including customer segments and technical designs representative for the mass market within two economic scenarios for Germany provide insights regarding the share of photovoltaic traction current and the competitive situation.
