1. 31. Greenhouse Gas Emissions Reduction in the Heavy-Duty Transport Sector - A Case Study of Renewable Energy Carriers in Sweden

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Karolina André; William Degerstedt; [2021]
   Keywords : Battery electric vehicle; Biofuels; Greenhouse gas; Heavy-duty vehicles; LCA; Renewable energy carriers; Renewable fuels; TCO; Transport sector; Well-to-wheel; Technology and Engineering;

   Abstract : Den svenska transportsektorn står för ungefär en tredjedel av landets totala utsläpp av växthusgaser och släppte 2019 ut 16,4 Mt CO2-ekvivalenter. Av dessa står den tunga vägtrafiken för cirka 20 % och är efter passagerarfordonen den största källan till utsläpp av växthusgaser inom sektorn. READ MORE

3. 32. Horses vs. Machines: A Comparative Energy Analysis between Eighteenth Century- and Modern Copper Mining

   University essay from Lunds universitet/Humanekologi

   Author : Amos Strömberg; [2021]
   Keywords : Copper mining; embodied energy; small-scale mining; degrowth; copper ore grade; Podolinsky’s principle; large-scale mining; 18th century mining; mining; Social Sciences;

   Abstract : This study shows the positive benefits of early 18th century copper mining in terms of energy efficiency due to the utilization of animate power, pre-industrial machinery, biofuels and a small-scale of organization. Based on the concept of embodied energy, this study calculates the inputs in early 18th century Falun Coppermine in Sweden and compares it with present-day Chibuluma Coppermine in Zambia. READ MORE
