| The objective of this study was to determine the relationship between farm size and energy productivity of wheat production in west Azerbaijan province, Iran. Farmers with different farm sizes (less than two hectares, between two and five hectares and more than five hectares) were randomly selected. Questionnaires were filled by 61 farmers. Then total used energy, produced energy, energy productivity and energy ratio were calculated for each farm. Also the relationship between energy indexes and three methods of tillage and planting (combination machine, seed drill and seed spreader) and three harvesting methods (combine harvester, mower and hand tools) were calculated. The data were analyzed by SPSS software. The results showed that fertilizers... |

| The amount of energy and food consumed in Puerto Rico is more indicative of a developed nation than one than is underdeveloped. All the energy consumed in Puerto Rico is from fossil fuels, while the agricultural sector marginally provides the needs of the consumer. In addition, the animal production sectors rely exclusively on imported feedstock for the preparation of feeds. There is a potential to develop an ethanol industry based initially on sugarcane, as the main feedstock and then turn to biomass from energy cane and or organic solid waste in the future. In order to move to the second generation of ethanol production, the cellulosic ethanol industry has to become economically viable. A limiting factor in the use of sugarcane is that only 40,000 ha are... |

| The external costs of electricity generation can be characterised by the resulting social and environmental impacts. The most significant impacts are the air pollutions impact on health, built in environment, crops, forests, agricultural areas and on global warming. The primary impact considered is the air pollution’s effect on human health. The monetised value of the health impact, the external costs are calculated for two regional coal power plants, the effects are examined on the EU level with the ExternE methodology. |
