This paper studies the impact of age and reactor technology on safety in the French nuclear fleet between 1997 and 2015. We use a novel dataset encompassing over 19,000 nuclear safety events declared by plant managers to the French regulatory agency. A major problem for evaluating the effects of age and technology is that declarations of safety events are influenced by the plant managers’ level of transparency [...]

Using household-level data from the American Housing Survey, this paper assesses the cost of adapting housing to temperature increases. We account for both energy use adjustments and capital adjustments through investments in weatherization and heating and cooling equipment. Our best estimate of the present discounted value of the cost for adapting to the A2 "business-as-usual" climate scenario by the end of the century is $5,600 per housing unit, including both energy and investment costs [...]

Has patient experience or patient experiential knowledge the potential to constitute other means of doing science and technology? Does it represent an alternative to mainstream science? Has it the power to question it, to challenge it, to make it more “democratic”? To try to answer this question, I contrast two sets of configurations: the first one concerns patient groups and I will try to recap what we have learnt from what they do with experience; the second one is centred around activities of private actors as well as researchers or institutions who have decided to give patient experience an important role in research, promoting the notion of “patient centred care”, the involvement and the participation of concerned people to research and research drawing on what is called “patients’ reported outcomes” [...]

Assessing the risks of rare disasters due to the production of energy is paramount when making energy policy decisions.
