  3. 22. Improving Ship Energy Efficiency through a Systems Perspective

    Författare :Francesco Baldi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; shipping; exergy analysis; energy systems; energy efficiency; energy analysis; systems analysis;

    Sammanfattning : The last years have been particularly challenging for the shipping industry. Fuel prices have increased to levels only seen during the oil crisis in the 70's, and environmental regulations have grown much stricter than in the past. Climate change, at a global level, is going to become a major threat to society. LÄS MER

  4. 23. Efficiency Analysis of Drive-train for an Electrified Vehicle

    Författare :Ali Rabiei; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drive cycles; Current vector control; Vehicle applications; Silicon carbide; Power electronics; Energy efficiency; Loss calculation; Electric machines;

    Sammanfattning : In this PhD thesis, various solutions to improve the energy efficiency in the electrical drive-train of an electrified vehicle such as modifications of the propulsioninverter or control of the electric machine, are proposed and their benefits arequantified from an energy efficiency point of view. The efficiency analysis isbased on modeling of a power electronics inverter, an electric machine and a battery in various drive cycles for an electrified vehicle. LÄS MER

  5. 24. Essays on energy efficiency, environmental regulation and labor demand in Swedish industry

    Författare :Golnaz Amjadi; Lars Persson; Tommy Lundgren; Luis Orea; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Energy efficiency improvement; rebound effect; stochastic frontier analysis; data envelopment analysis; stochastic energy demand frontier model; persistent and transient energy inefficiency; energy inefficiency; environmental expenditure and environmental investment costs; output demand elasticity; Economics; nationalekonomi;

    Sammanfattning : Paper [I] Energy efficiency improvement (EEI) benefits the climate and matters for energy security. The potential emission and energy savings due to EEI may however not fully materialize due to the rebound effect. LÄS MER
