1st of may 2003, a new energy system based on electricity certificates, was initiated in Sweden. The purpose with this system, is to stimulate an enlargement of energy production from renewable sources. The electricity system, ist built on that the producers of energy from …
… to and in between the four price areas in Sweden are included. Consumption of electricity, other electricity generation and wind power are in the form of time series. In practice, the hydro power’s ability to follow given variable net load is simulated. Different levels of …

… group can now buy the small wind turbines in order to cover their own usage of electricity. It could be farmers which want to produce their own energy in order to cover their high energy consumption. It could also be land owners who would like to make use of their land and …
Lönsamhetsanalys genom simulering av solcellsanläggningar och explorativ kundundersökning
This thesis is commissioned by the Swedish electricity trading company GodEl with the purpose of evaluate solar electricity in multi-family buildings in the Stockholm region. The prices of solar panels have dropped recently due to the advances in technology, but the installation …
Utredning av åtgärder för ventilation, värme och kyla
… for the different areas have been divided into two different parts, electricity- and heat consumption. Electricity consumption is roughly 500 MWh per year and the heat consumption is around 1020 MWh per year. This is only the consumption of the areas that have been investigated …
… 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 …
The main purpose of this project was to make a survey of the steam and electricity consumption at Akzo Nobel Functional Chemistry AB and give suggestions of how to minimize them. These three different areas were focused on. First to make a survey of all the most important …
… for this parameter in question. Parallel with the study of Energy Director electricity on the margin, calculations of carbon dioxide equivalents and also the Swedish trade of electricity have all been highlighted. Results indicate that when reductions in energy are made it is …
… result was that the metro based on the worst-case scenario (marginal electricity) had such good results. It had one result that was the highest of them all, SO x . In the overall standings (cost for the society, sek/pkm) though it was only beaten by the other electricity mixes …
Jämförelse mellan tre utvecklade versioner av ett vattenvärmedrivet torkskåp
Abstract Electricity consumption is a globally increasing problem caused by the high share of electricity produced in coal power plants. These contribute to high carbon emissions when only about 1/3 of the heat generate electricity and the remaining 2/3 of the heat cools off …
… of HPW Fresh & Dry Ltd., a fruit drying factory in Ghana. The factory produces electricity with diesel and biogas but also purchases electricity from the national electricity company. Heat for the drying process is produced from biogas, kerosene and solar panels. In the project …
Utveckling, implementering och utvärdering av visualiseringsverktyg för minskad elanvändning
This thesis examines the effects of electricity visualization in an office building. The subject was investigated through the creation of a web based visualization tool that was made accessible to the about 1500 employees in a large office building. The visualization was …
En studie som syftar till att identifiera utvecklingsmöjligheter för att uppnå ett mer hållbart energisystem år 2030
Feedback tools support electricity users within the Swedish residential sector to increase their knowledge of electricity and the electricity market as well as to become more aware of their electricity consumption, which in turn encourages a reduction and an increased …
