Lokal energiförsörjning i byn Vasselhyttan
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 which are dependent on electricitiy 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 estimate the possibilities for the farmers 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 Vasselhyttan, located 20 km north of Lindesberg, was selected as an object for the investigation. The district is dominated by forest. The population of the village is 200 people. The first part of the work was to establish the attitudes held by the inhabitants of the village and by the municipality. Generally the attitudes was positive to a local production of energy. Most of the inhabitants considered woodfuel to be the best source of energy. Some of them also suggested biogas as a good alternative. Due to the aspects described above and to the high potential of forest in the area we choosed to concentrate on fuelwood produced in forest and on cultivated land. We looked upon the possibilities to produce biogas from manure and silage as well. These energy sources were investigated in three different alternatives. Two of them also included. a sun-collector system, The conclusion we made, aming these alternatives, was that a system with a separate furgace for woodfuel in each house was the most suitable. This conclusion was made after considering; * the asset of fuelwood from the surrounding forest * the custom of the inhabitants and the structure of the village * the increase of the laboryeeds * the environmental effects sustained by the fuelwood According to the economical aspects, a local production of energy in Vasselhyttan 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 conclusion 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 Vasselhyttan has a good potential for a future local production of energy.
