TU Delft's education as a driver for Photovoltaic Deployment to achieve Climate Neutrality by 2050

TU Delft’s education as a driver for Photovoltaic Deployment to achieve Climate Neutrality by 2050 A research paper by experts Arno Smets and René van Swaaij from the Delft University of Technology (TU Delft) focusses on the acceleration of photovoltaic (PV) deployment and the impact of education in attaining climate neutrality. Featured in the Renewable Energy and Energy Storage Systems collection of the Multidisciplinary Digital Publishing Institute (MDPI), the study underscores the pivotal role of education in realising the UN Climate goal of achieving net zero emissions by 2050. The research, which addresses key concepts discussed at a side event during COP27 on PV resources towards climate neutrality, explores the potential barriers to the transition, emphasising the need for comprehensive educational initiatives to empower stakeholders across various sectors. Portfolio for impact Among those examined, the portfolio of Energy Transition courses from the TU Delft Extension School of Continuing Education could provide valuable solutions to existing barriers. In particular, the paper recognises the impact of the first Massive Open Online Course (MOOC) on Solar Energy, launched in 2013. Its high popularity indicates a continuing strong demand for education in the field, particularly as the solar PV sector continues to expand, generating both direct and indirect employment opportunities. The online, self-paced format of the Energy Transition portfolio MOOCs (accessible for free to anyone with an internet connection), ensures the potential for widespread dissemination of knowledge, which is of added value to learners in low- to middle-income countries. The research also sheds light on the MicroMasters® programme by Arno Smets (TU Delft’s Research Group Photovoltaic Materials and Devices), which is designed for individuals with relevant engineering backgrounds. With 75% of its participants being professionals seeking to enhance their expertise in the field, it attracts diverse age groups and an increasing number of female participants. Image credit: Moritz Kindler on Unsplash Empowered to act It is remarkable how some learners, empowered by the acquired knowledge, translate this into applicable solutions, such as building PV systems in their homes or villages. The game-changing impact of the online courses is further illustrated by participants establishing solar businesses or making career changes within the energy transition sector. The courses are shown to equip individuals with technical skills and to also empower them to influence policy changes, overcome regulatory barriers, secure permits, and raise funding. The study concludes by remarking on how such education is already building awareness of other key energy transition concepts around public acceptance, energy communities, and land limitation – an understanding which is vital to a successful pursuit of the net-zero emissions goal by 2050. About the Authors Arno Smets is Professor of Solar Energy in the Photovoltaics Material and Devices group at the TU Delft Faculty of Electrical Engineering, Mathematics and Computer Science. He is also Director of Education at the Extension School for Continuing Education and instructor of the Solar Energy MOOC, which has already attracted over 150.000 students worldwide. René van Swaaij is Associate Professor in the Photovoltaics Material and Devices group at the TU Delft Faculty of Electrical Engineering, Mathematics and Computer Science. He is Programme Director of the MSc in Sustainable Energy Technology, and Academic Portfolio Director for the Energy Transition educational offer by the Extension School for Continuing Education Arno Smets Rene van Swaaij TU Delft Extension School for Continuing Education Founded in 2014, it is an innovation-oriented organisation focussed on actualising the University’s Lifelong Learning Strategy.

VOX Movie Night: Hannah & Her Sisters (1986)

VOX Movie Night: Hannah & Her Sisters (1986) 15 February 2024 19:00 till 22:00 - Location: TU Delft Library, Blue Room | Add to my calendar Register For the last film in our 'Joie de Vivre' theme, we will be showing a suggestion from one of our members: Hannah & Her Sisters (1986), written and directed by American cinematic institution Woody Allen. This movie was made during one of Allen's many creative peaks - one of the most prolific American directors of all time, he has managed to churn out a new film every year since 1982. Hannah & Her Sisters did not escape praise, it won three Oscar's upon its release (including Best Original Screenplay) and ranks as one of Allen’s most successful films at the box office. It boasts an ensemble cast including British icon Sir Michael Caine, Mia Farrow, and Woody himself in a minor-ish role, among other stars. The plot follows three successive family Thanksgiving dinners marking time for Hannah (Mia Farrow), her younger sisters Lee (Barbara Hershey) and Holly (Dianne Wiest) and the men in their lives. Lee is having an affair with Hannah's husband, Elliot (Michael Caine), and trying to end her Svengali-like romance with artist Frederick (Max von Sydow). Holly is frustrated by her lack of career fulfillment and her increasing dependence on Hannah's largesse, while being courted by the hypochondriac Mickey (Woody Allen). This film borrows a lot from one of Allen's greatest influences, the cinematic humanist Ingmar Bergman, featuring a narrative setup that is an homage to Bergman's Fanny & Alexander - only 'Woodified', one might say. It explores typical themes in Allen's oeuvre: The unpredictability of love and romance, taboo relationships, family, neuroses, religion, & the meaning of life. And, of course, it features his classic writing style, his wit comes at the viewer like a flurry of jabs from an agile boxer. Free! Themed drinks & snacks will be provided! Movie enthusiasts take note! TU Delft now has a film club that will meet every Thursday night outside of exam periods.

Tracing ancient settlements in Colombia with remote sensing

A team of the LDE alliance (Leiden University, TU Delft, and Erasmus University Rotterdam) asked whether it might be possible to search for signs of ancient settlements in the jungle with affordable remote sensing techniques. For an expedition in a Colombian dense forest, the team, including remote sensing expert Felix Dahle of TU Delft, joined forces with archaeologists and drone experts from Colombia. In mountainous forests, drones provide affordable access to areas that would otherwise be unreachable from the ground. A LiDAR laser scanner already proved its value in coastal observation . The big question was whether LiDAR could bypass the many treetops. Trees reflect the laser, so it was crucial to fly close so it found its way through the foliage. The team mounted a highly portable LiDAR laser scanner to a drone and went on expedition nearby ancient terraces of the Tairona culture in the Sierra Nevada of Santa Marta. “We had to find the sweet spot. Close to the archaeological sites and still secure above the canopy”, says Felix Dahle. And it passed the test. The LiDAR laser scanner create a point cloud and a detailed 3D model of the landscape. “We were able to detect ancient terraces in the jungle. We discovered that we can scan through the forest when it is not too dense, but some areas remained unfathomable. We could also distinguish several types of vegetation, which might be of great use too to find undiscovered archaeological sites.”
