Research in solar energy is taking big steps in both solar heating and solar electricity. It´s not only the technologies alone, but also the combination of both solar electricity and solar heating which is what is called a solar hybrid. The idea of a solar hybrid is that a solar …

The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. The use of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere. This is the main motive but also a wish of higher safety, that is a higher rate of …
… solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in …
jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala
… other with non-pasteurized substrate. For the present pasteurization system, electricity and heat demand was surveyed. For the integrated thermophilic sanitation, a process design was developed and dimensioned and the electricity and heat demand was calculated. Thereafter, the …
… when the supply of renewable energy is minimal. A large part of the needed electricity may be covered by electricity from solar cells mounted on the roof, balcony fronts and facades. A reduction of purchased electricity has a major impact on the building's stress on the …

… hall, laboratories and storage areas. The energy audit showed that the electricity use is far greater in hus A, compared to the an average office and administration building. This is mainly due to production processes. A breakdown of the highest electricity consumers are …
… use in the biogas production. The energy survey was divided into two parts: electricity and heat. Each part was treated separately and with somewhat different approach. To estimate the electricity usage during the projcet the rated power of each selected unit operation was noted …

… profitable, while the NPV is a more accurate method. CHP plants produce both electricity and heat for consumption. They have a high efficiency between 80-90%. Previous studies show that Sweden is in a situation where they need to install more CHP to expand the district heating …
The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue …
En fallstudie på SSAB EMEA i Borlänge
… cooling, which may increase the need for waste heat in the summer and in-house electricity production, which can accommodate some of the steel company's electricity need. A few threats to a continued use of waste heat have also been identified, which the first consists of …
… of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner. The purpose with this rapport was to do a basic study for the specific system at Arvika where it’s possible to see the potential production of electricity that …
