- Deepwater Horizon oil spill : stock performance effects on the energy industryPublication . Pereira, Pedro Miguel da Fonseca; Stahl, JörgThis dissertation investigates the financial implications of the largest marine oil spill in history (Deepwater Horizon oil spill) on the Oil and Gas and Alternative Energy industries. Employing event study and regression methodologies, the analysis spans US and European markets to assess intra-industry and cross-industry effects, with a focus on the role of Gulf of Mexico exposure in driving abnormal stock returns. Findings confirm significant negative market reactions for BP and its partners, with severe negative cumulative abnormal returns reflecting strong intra-industry contagion. The research further highlights the disproportionate impact of negative news on market reactions compared to positive developments, suggesting investors tend to overreact to adverse events. Additionally, exposure to the Gulf of Mexico during the spill was identified as a key driver of abnormal returns. The study provides key insights for stakeholders in assessing financial risks associated with environmental disasters and offers a foundation for further exploration into long-term industry ramifications, such as regulatory impacts and shifts in energy policy.
- Education : the key factor in developing Livo’s customer journeyPublication . Cintra, Teresa Vaz de; Xavier, RuteThis dissertation Education: The Key Factor in Developing Livo’s Customer Journey under Professor Rute Xavier’s supervision, explores how education can enhance Livo’s customer journey in integrating energy-efficient solutions into Ageas Portugal's insurance offerings. A mixed-methods approach was used to evaluate strategies, understand barriers, and uncover cross-selling opportunities. The research highlights the need to address two primary barriers: lack of consumer knowledge and financial constraints. Educational campaigns and clear communication can bridge awareness gaps, encouraging informed decisions. Moreover, emphasizing long-term cost savings and offering financing options could mitigate financial challenges. Key findings show that integrating Livo’s sustainable solutions with multi-risk insurance packages can elevate customer satisfaction and loyalty. Recommendations are structured around three phases of the customer journey, in the pre-purchase phase to build awareness through targeted campaigns, educational materials, and modular solutions tailored to diverse customer profiles. In the purchase phase to simplify decision-making with transparent pricing, and bundled incentives emphasizing long-term savings. In the post-purchase phase to reinforce trust with follow-up protocols, performance reports, and personalized service updates. The study concludes that aligning sustainability with insurance offerings presents significant opportunities for value creation. By addressing informational and financial barriers, Livo and Ageas can redefine the customer experience, enhancing loyalty and contributing to a sustainable future.
- Logotype change and perceived quality : an analysis of the new EDP brand imagePublication . Oliveira, Maria Francisca Tavares de; Fernandes, Anna Carolina Boechat ChavesEDP, a major Portuguese energy company, recently underwent a rebranding process and unveiled a new logo. The new logo represents a change in the company's visual identity, with the aim of reflecting the evolution of its values and strategic focus on sustainability and innovation. The updated design features a more modern and simplified aesthetic compared to the previous logo, which had a more traditional appearance and was red. In the context of brand strategy, a strong brand identity is very important for establishing a distinctive brand image and improving customers' perception of quality and reliability. Given the importance of these elements for business success, this research aimed to assess the impact of EDP's new logo on perceived brand quality. The study collected opinions from a sample of 242 Portuguese participants to assess how the rebranding influenced the perceived quality of the EDP brand. For this purpose, quantitative methods were used, collected through an online survey. The conclusion is that the change of logo is generally evaluated positively, establishing an association with sustainability and the energy transition. However, it is important to note that a significant proportion of the sample was not fully aware of aspects of the new logo, suggesting the need for marketing efforts to bridge this gap. It was also observed that the brand was already perceived with high levels of perceived quality, positive image, reputation, association with sustainability, quality of service and overall positive opinion. Based on these results, it was clear that the new logo has no impact on perceived quality, since this variable remained at the same high level with both the new and old logos.
- A managerial perspective on generative AI’s role in digital twin- enabled positive energy districtsPublication . Schmidt, Vanessa; Bohnsack, RenéAs cities worldwide strive toward more sustainable energy systems, Positive Energy Districts (PEDs) have emerged as a promising approach to achieving net-positive annual energy balances. However, the complexity and variability of urban energy supply and demand pose significant challenges for effective energy management. This thesis investigates how the integration of Generative Artificial Intelligence (GenAI) with Digital Twin (DT) technologies can enhance PEDs. Based on a comprehensive literature review, project proposals, and qualitative interviews with industry experts, the research explores how GenAI can strengthen DT capabilities by improving forecasting accuracy, scenario testing and resource allocation. Key findings show that GenAI can fill data gaps, support adaptive modelling and facilitate proactive energy distribution decisions. In addition, the research identifies organisational and regulatory barriers - such as privacy, interoperability standards and the need for capacity building - that must be overcome to realise these benefits. By providing actionable insights into how GenAI can augment DTs, this work contributes to the theoretical and practical knowledge of sustainable urban energy systems. It highlights the importance of strategic planning, stakeholder collaboration and robust governance mechanisms to guide managers and policy makers towards more efficient, equitable and forward-looking energy solutions in DTs.
