| + | By distributing control capabilities to each component in the electrical grid and enabling the exchange of information between components, the grid gains a higher degree of control and flexibility | ||
| + | This allows for better risk management and higher resilience in the event of sudden peak loads or other stressors. | ||
| + | However, even though Smart Grids are intended to reduce risks to power grids, their own future is exposed to significant uncertainties. Thus, the development and expansion of these systems depend on a number of factors that make quantitative risk calculations difficult: the magnitude of the required investment, uncertainty regarding technological developments, | ||

| - | Science is undergoing a profound transformation, | + | - Similar to Resiliance, how to mitigate risk, Risk manegement (how would that look like in the case of Critical infrastructure like power grids) |
| - | According to Funtowicz and Ravetz, the interaction between decision-making stakes and system uncertainties determines which problem-solving strategy is appropriate. They distinguish three distinct types of science: applied science, professional consultancy, | + | - Risk analysis |
| - | Applied Science: This operates when both system uncertainties and decision-making stakes are low. Here, problems are managed using routine, standardized procedures; the uncertainties are purely technical, and the outcomes do not carry immediate, high-stakes political or societal risks. | + | |
| - | Professional Consultancy: | + | |
| - | Post-Normal Science: This strategy becomes essential when both system uncertainties and decision stakes are high, conditions common to environmental and public health crises. In this realm, urgent decisions must be made despite severe data gaps, and the conflicting values of diverse groups mean that traditional scientific consensus is impossible. | + | |

| + | - New Risks like the rise in the Frequency of natural disasters due to climate change raises questions about the need to insure critical infrastructure aswell as the potential rise of the cost of the insurence. Furthermore the rising need to ensure and the rise in costs of insurence, will have consequences for future investments for the expansion and modernisation of critical infrastructure as well as consequences on the cost for the end user | ||
