“…The analysis on energy potential in this study has taken an average national holding and specific household holdings. The energy potential from biomass is divided into four types as theoretical energy, technical energy, economic energy and achievable energy potentials [15,48]. Theoretical (gross) potential refers to the amount of energy produced from available biomass resources (land and cows) taking their gross heating value into account.…”

Abstract:Up to the present day, wood has been used to supply the needs for cooking in rural Africa. Due to the ongoing deforestation, households need to change to other energy sources. To cover this need, a large amount of people are using residues from agriculture (straw, manure) instead. However, both straw and manure also have a function in agriculture for soil improvement. Using all the straw and manure will seriously affect the food production. In this paper we first determine the amount of energy that households need for cooking (about 7 GJ per year). Then we estimate the amount of residues that can be obtained from the agricultural system and the amount of energy for cooking that can be derived from this amount when different conversion techniques are used. The amount of residues needed is strongly affected by the technology used. The traditional three stone fires require at least two times as much resource than the more advanced technologies. Up to 4 ha of land or 15 cows are needed to provide enough straw and manure to cook on the traditional three stone fires. When more efficient techniques are used (briquetting, biogas) this can be reduced to 2 ha and six cows. Due to large variation in resource availability between households, about 80% of the households own less than 2 ha and 70% holds less than four cows. This means that even when modern, energy efficient techniques are used the largest share of the population is not able to generate enough energy for cooking from their own land and/or cattle. Most rural households in Sub-Saharan Africa may share similar resource holding characteristics for which the results from the current findings on Ethiopia can be relevant.

“…In Macedonia (Kanevce et al 2016) the biomass accounted for 6.6% of the primary energy consumption in 2012, and 10.4% in the final energy consumption. The biomass residues potential were calculated on similar way in Albania (Karaj et al 2009) Turkey (Elicin et al 2014, Italy (Chinnici et al 2015) etc. and shows importance of studies for assessment of biomass potential and availability.…”

SUMMARYThis paper gave an overview of the energy potential of organic remains from agricultural primary production and waste from livestock production in Montenegro. It has been estimated that approximately 9490 tons of dry mater of agricultural plant production residue is available. Intensive livestock farming results in production of 107.675 tonnes of waste.The estimation of technical energy potential of crop residues amounts about 142.283 GJ (39,56 GWh). The technical potential calculated on the basis of the availability and total animal fund results in total of 298.552 GJ (82,93 GWh) of energy potential. Technical energy potential of agricultural waste is about 440.835 GJ (122,49 GWh) per year. This potential is significantly lower than the theoretical potential.

“…Potential of energy generation from processing residues was 511946175 kWh/year (52.80% of total potential) while from field residues was 457643230 kWh/year (47.20% of total potential). Base on the CO2 emission from electrical energy production in Iran that is 0.572 kg/kWh [21,22], mitigation potential of CO 2 emission, as a result of using crop residues energy in Shodirwan, was 554605 tonnes/year. Spatial potential of energy generation from crop residues in Shodirwan are illustrated in Figure 4.…”

“…A number of technologies with different efficiency exist for power generation from biomass. Agriculture biomass energy potential of wheat, corn, barley, rye, paddy, bagasse and other crops was estimated with combustion processes as direct fuel [1,8,[19][20][21]. An overall efficiency of 30% was chosen, which a reachable level under current available technology is [21].…”
