Abstract:

Climate scientists have shown convincingly that the world is heading rapidly towards a cliff, a point-of-no-return, if we do not succeed to quickly reduce our emissions of green-house gases susbstantially. The two parts of the 44th Heidelberg Physics Graduate Days 2020 will offer a detailed discussion of the climate problem and the possible solution, increased energy efficiency and rapid introduction of renewable energy (RE). In this part, we will discuss in detail what is needed to have a chance of success in this challenging task. We will start with an overview on what is needed for a transformation of the global energy system, and how an energy system approaching more and more efficient use of ultimately 100% RE can provide secure and reliable energy supply for all sectors of the economy. On the second day, we will discuss the available RE, with a special focus on solar photovoltaics. The third session will focus on the role of energy storage, battery technologies and especially the central role of hydrogen. In the last session, the individual components presented in the first sessions will be put together, for a discussion of decarbonized transporation, the future power grid and, finally, try to give an answer on the key question: Will those technologies and Innovations allow to avoid the most catastrophic consequences of global climate change?
