Lokal energiförsörjning i Kjulaby : resurser och möjligheter
Färdal, Anna; Ilskog, Elisabeth
The main purpose of this survey is to investigate the possibility of a decrease in the dependency of electricity in the rural areas. The households wich are dependent on electricity as the basic source of energy will have problems at the time of the winding up of the nuclear-power stations. The aim of this investigation is to produce local energy for heating as a complement to the traditional food production. The investigation is carried out for the Department of agricultural engineering in Uppsala at the request of the State Department of energy. The village of Kjulaby, located some 10 km east of Eskilstuna, was selected as an object for the investigation. The district is dominated by cultivated land. The population of the village is about 40 people. The first part of the work was to research the attitudes held by the inhabitants of the village and by the municipality. Generally the attitudes was positiv to a local production of energy. However, half of the inhabitants were doubtful concerning the implementation of the idea. Most of them concidered straw to be the best source of energy. The possibilites for a municipal contribution was available as well. Due to the aspects described above we choosed to concentrate on straw and windpower. These energy sources were investigated in two alternatives. One of them also includes a sun-collector system. The conclusion we made was that a system using straw for heating was the most suitable. The households in the village were then connected to a central heater. This conclusions was made after concidering: * small amount of pollution origined from the burning of straw * increase of labour needed * grain grown in the area is concentrated close to the village * low alternative value of the straw * flexibility of the system, as other crops can be used as well. At present there is no system for transport of the heat so the investment costs would be high. According to the economical aspects, a local production of energy in Kjulaby can only become a reality if the price of electricity is highly increased. A decision of a more forceful energy price policy in the nearest future would be desirable. Until then no conclusions can be made. However, the energy taxes and fees can be used to give priority to energy produced from biomass. If that is the case, we think that Kjulaby has a good potential for a future production of energy.
