… in Sweden uses 15 000 kWh for heating, 5000 kWh for tap water and 5000 kWh for electricity. These figures are based on each household using 14 000 kWh for heating, 5000 kWh for tap water and 8100 kWh for electricity. A wood furnace delivers the heat and the electricity is bought …
… 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 …
… is often one of the most efficient alternative when it comes totransport. An Electric bike is, and makes transportation more efficient than a regularbicycle. Electric bicycles do not affect the environment significantly and allows moreconvenient transportation than ordinary …
… hopefully can reduce parts of this need. They are currently testing their two electrical busses (with Hybrid backup) in city traffic on the roads of Umeå in cooperation with the county of Umeå. The busses are originally diesel-busses, but the diesel motor has been replaced with …
Vattenfall hedge its future electricity production in order to decrease fluctuations in theresult. Hedging can in a simplified way be described as selling the future electricity deliveriesin long-term contracts so that the future price of the delivery becomes fixed. The …
… in a business model which offers Svenska Kraftnät an increased volume of electricity production through free capacity in CHP plants. This stabilizes the national energy system when the electricity production from renewable energy sources is low. Free capacity occurs due to more …
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 …
… 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 …
… a lot of electronics that needs battery power to work. In addition to that electric propulsion systems have gotten more popular lately, which further increases the demand for high battery capacity. The batteries used are mostly lead-acid batteries and to get the most out of the …
En studie som undersöker möjligheter och hinder i utvecklingen av det svenska elsystemet
Distributed, renewable generation-units and more efficient use of electric power,demands a developed electric grid. This grid is often referred to as the ”Smart Grid”. This future electric system rise expectations among actors in the existing electricmarket. International …
… to use to produce energy as well as to store that energy. To produce heat and electricity to the house I decided to use a wind turbine and a solar water heater. The most difficult part of designing a house that is energy independent is that the produced energy must be stored …
Diesel electric propulsion is in many ways a good alternative to conventional shaft propulsion, both economically and environmentally. There are also many other good side effects which need to be considered, i.e. better manoeuvrability, more efficient use of space and less noise …
… consumption. The transition time for this change was due July 2009. Hence all electric companies had to find a solution to automatically collect meter data before that date. For those of you who earlier have not been involved in the business areas of electricity and power there …
Identifiering av för- och nackdelar med nätstationsmätning, Mälarenergi Elnät AB
Today’s electrical grid companies understand that better knowledge of and information about their grid can help realize a smart grid network. One way to gain better knowledge and information about the low voltage network is to install measuring equipment on the substation …
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 …
