Both the European and the Hungarian rural areas suffer multi dimensional problems. Beside infrastructural under development the most important difficulty is employment. Unemployment is significant in the rural areas, while other structural characteristics like education, profession, work circumstances and seasonality worsen this unfavourable si...tuation. It can be stated that the challenge with the highest priority in rural and spatial
development is to create jobs and to strengthen local employment. The authors examine the job generating possibilities of energetic biomass of agricultural origin in a structural point of view. The aim is to develop spatial biomass product line models that permanently support the raise of employment by utilizing the possibilities of the European Union support policy and the popularity of this branch.
Energy plays an important role in everyday life and in the economy. The use of fossil energy sources greatly damages the environment. Besides this, the quantity of these energy sources is limited. Therefore, it is important to increase the share of renewable energy sources (solar, wind, water, biomass) in energy generation. Huge amounts of ener...gy (1150-1300 kWh/m2) arrive at the earth from the sun, which utilized in passive and active ways. One of the active applications is photovoltaic current production, in the course of which electricity is produced directly with PV-Panels. This can be fed into the grid.
The guiding principle for our research is that decentralized energy supply systems should be located near local consumers. One big, local market for energy from biogas plants in Hajdú-Bihar county is Debrecen. In the course of the investigation of biomass suitable for biogas production in the area of Debrecen, this study determines the quantit...y of biogas producible from animal manure. Municipalities around Debrecen were examined in circles with 40, 20 and 5 km radius. Livestock data of these settlements stem from the Agricultural Census in year 2000, actualized by the county trend of livestock changes. Manure quantity and biogas potential in these places are estimated with coefficients from the literature and our calculations. In the largest circle, about 1.4 million tons of manure is produced, from which round 94 million m3 biogas can be produced. Biomass produced in the settlements and producible biogas shows a remarkable trend of concentration, which supports our recommendation on the system of energy supply.
By joining the European Union, Hungary made a commitment to increasingly utilize renewable energy sources. Keeping in view the agricultural circumstances of Hungary, we can state that biomass utilization has, overall, the greatest range of possibilities to use its products as ‘energy sources’. Biomass raw materials are useful in meeting emi...ssion control regulations for environment protection and to reduce climate change. The role of biomass production in spatial and rural development and in rural employment, and also in the decrease of Hungary’s energy dependence, supports development in biomass energy use. My aim in studying biomass utilization is the creation of a micro-regional level, decentralised, agro-energetic system-model for the use of plant and animal biomass for energy purposes, whether naturally or by anthropogenic activity, on agro- and sylvicultural areas, and on animal breeding farms. This model simulation method serves as a planning base for policy-makers during the spatial planning processes. The examination is presently in the stage of data collection. The collection of the basic data of the examination area and the purchase of the necessary equipment, materials and maps has already started. Contact has been made with local stakeholders, municipalities, municipality associations and micro-region managers.
