  1. 1. Are renewable sources displacing fossil fuels in electricity generation? : A panel data investigation on global data

    Kandidat-uppsats, Högskolan Dalarna/Nationalekonomi

    Författare :Andreas Sörling; [2023]
    Nyckelord :Climate change; Energy transitions; Green Growth; Displacement Paradox; Jevons Paradox; Panel Data;

    Sammanfattning : As the consequences of climate change is increasing the need of replacing fossil fuels with renewable energy globally is becoming more urgent. A central question that has been questioned in the literature is that if the world is on track on a transition away from fossil fuels or if we are only adding renewable energy to the energy mix in a world that continues to grow and consume more energy.

  7. 5. Developing an innovative unit of power supply to improve the sustainability of data centers : A techno economic analysis of replacing diesel generators with fuel cells as backup power generation for data centers

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Filip Agrell; Agit Ablay; [2022]
    Nyckelord :Fuel Cells; Hydrogen; UPS;

    Sammanfattning : As the amount of data centers continues to increase, their electricity consumption and emissions are being reviewed. The current backup solution is a conventional diesel generator running on fossil fuels. As part of climate goals to reduce carbon emissions, renewable energy sources like fuel cells running on hydrogen are being considered. LÄS MER
