comparing biogas production to incineration
… for utilization of the biogas werealso compared through LCA, generation of electricity and the use of thebiogas in heavy vehicles.From an environmental perspective production of biogas is a better way totreat OFMSW than incineration. When biogas is used for electricitygeneration …
-Ur ett tekniskt och ekonomiskt perspektiv
… property-investments. The unusually cold winters along with extreme prices of electricity in Sweden in recent years has also contributed to increased interest in energy-efficient buildings. The process of developing a modern family home in Kiruna, Sweden is presented the first …
… parts are emissions of green house gases from the farming and the use of electricity from the machines in the processes which also gives emissions of green house gases. When the shirt is laundered by the user, he or she is contributing to the use of energy, but this depends on …
En utvärdering av värdeflödesanalys och miljövärdeflödesanalys
… in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines.
… of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer. The company Minesto has developed a technology that is called Deep Green …
En undersökning av huruvida solceller är ett fördelaktigt energisystem med avseende på tekniska och ekonomiska aspekter
… that have been considered are heating, ventilation, sanitation and electricity. Construction calculations and material selection are also discussed. Furthermore, a study about photovoltaic cells has been done. The purpose of the study is to decide whether photovoltaic cells are …
… inhabitants, a great number of different heating/cooling customers and 40,000 electricity customers.In the future, it will be required by HEM to integrate intelligent energy solutions, where energy consumers are increasingly micro generation and able to control their energy …
… main areas is made. Primarily the photovoltaic system is sized based on the electricity consumption in the buildings. Furthermore an assessment is made whether or not the photovoltaic system is a profitable investment. Lastly a comparison between the output of the analysis and …
Electricity production from renewable energy resources such as wind energy and photovoltaics is variable. Integration of these intermittent resources into the electricity system leads to new challenges in how to manage imbalance between supply and demand on the grid. One way to …
