In the search for appropriate
solutions, architects and stakeholders need ways to reason about
concepts and their impact. The understanding, communication, and
reasoning facilitates decision making. In this keynote, we explore
conceptual models as the means to achieve all of these needs. We will
make the abstract notion of conceptual models concrete by using future
energy systems as an application area. Renewable energy systems have to
help in solving the global sustainability development goals, especially
the energy transition. The dynamics of both supply and demand of energy
increases the complexity of the future energy systems.
