11. Energy Efficiency Versus Gains in Consumer Amenities
Sammanfattning : This thesis, consisting of five papers, addresses the question of what share of technological development results in increased energy efficiency rather than offsetting improved consumer services in the form of gains in consumer amenities? In the first paper economic and organizational explanations are given for stagnating energy efficiency trends in the Swedish residential building sector. The results show that changes in energy prices to a large extent explain the observed stagnation. LÄS MER
12. The Role of Plug-in Hybrid Electric Vehicles in Electrifying Personal Transport
Sammanfattning : The Paris Agreement emphasizes the importance of greenhouse gas mitigation in the transport sector to address climate change and create a sustainable future with lower carbon emissions. Plug-in hybrid electric vehicles (PHEVs) can be helpful in reducing greenhouse gas emissions in transportation when combined with efforts to decarbonize the electricity sector. LÄS MER
13. Energy Efficiency in Winter Road Maintenance - A Road Climatological Perspective
Sammanfattning : Practices in winter road maintenance are dependent on the climate and weather impacting roads and the road users’ requirements. As in many other fields of transportation, it is of interest to investigate fuel efficiency potentials in the different aspects of the road maintenance area. LÄS MER
14. Challenges for end-use energy efficiency
Sammanfattning : The scientific community has reached close to a consensus that anthropogenic emissions of greenhouse gases are causing a change of the global climate. These emissions arise foremost from the burning of fossil fuels, and secondly from land use change. LÄS MER
15. Alternative Combustion Strategies for Gasoline Engines
Sammanfattning : Due to increasingly strict legislative demands and customer concerns regarding CO2emissions, there is a need to develop and implement new combustion strategies forgasoline (Otto) engines. In attempts to meet this need, most attention is focusing onthe low load/speed range where the classic spark ignition strategy (SI) has poorefficiency, mainly due to the throttling of the intake air causing pumping losses.
