Current intensive grain crops production is often associated with environmental burdens. However, very few studies deal with the environmental performance of both current and alternative systems of barley production. This study was undertaken to evaluate energy consumption and environmental impacts of irrigated and rain-fed barley production. Additionally, three alternative scenarios were examined for irrigated barley fields including conservation tillage and biomass utilization policies. The findings showed that around 25 GJ/ha energy is needed in order to produce 2300 kg/ha irrigated barley and 13 GJ/ha for 1100 kg/ha rain-fed barley. Life cycle assessment (LCA) results indicated that irrigated farms had more environmental impacts than rain-fed farms. Electricity generation and consumption had the highest effect on the abiotic depletion potential, human toxicity potential, freshwater and marine aquatic ecotoxicity potential. However, alternative scenarios revealed that using soil conservation tillage systems and biomass consumption vs. gas for electricity generation at power plants can significantly mitigate environmental impacts of irrigated barley production similar to the rain-fed conditions while higher yield is obtained.

Los procesos de generación de electricidad a partir de combustibles fósiles son fuentes de contaminación ambiental, siendo una preocupación actual de los países en desarrollo. El objetivo del presente trabajo fue evaluar el impacto ambiental de la generación distribuida de electricidad en una central de 110 kV por medio del Análisis del Ciclo de Vida para la determinación de mejoras en el proceso. El Análisis del Ciclo de Vida (ACV) se realiza de acuerdo con los requisitos establecidos en la NC ISO 14040: 2009, utilizando el Eco-indicador 99 del software Sima Pro 7.1. Los impactos ambientales se evalúan a partir de un análisis de inventario en cada una de las etapas del proceso, contabilizando las entradas y salidas de materias primas, energía y emisiones al aire, agua y suelo, para lo cual se realiza un diagrama de flujo del proceso. A partir del análisis de los flujos, se determinó que los parámetros condenatorios en el caso de los efluentes, sólo se cumple para el pH y la conductividad eléctrica, en el caso de las emisiones al aire se viola con el NO2 y SO2. Los resultados muestran que la etapa de mayor contribución se concentra en el área de generación y los productos más agresivos al ambiente son el consumo de fuel oil (80 % para la salud humana, 53 % para el ecosistema y para los recursos naturales 95 %) y el producto residual de la limpieza de los materiales de explotación (en el caso del ecosistema 35 %). Abstract The electricity generation process from fossil fuels its source of environmental pollution, being a current concern at developing countries. The objective of the present work was to evaluate the environmental impact of the distributed electricity generation in an 110 kV oil fuel power station using the Life Cycle Assessment method to determinate improvements in the process. The Life Cycle Assessment (LCA) was perform according to the requirements established in the NC ISO 14040: 2009, using Eco-indicator 99 with software Sima Pro 7.1. The environmental impacts were evaluate starting from an inventory analysis in each stage of the process, accounting the inputs and outputs of raw materials, energy and emissions to the air, water and soil; a flow diagram of the process was generated for the assessment.  From the analysis of the flows, it was determined that the condemnatory parameters in the case of effluents, is only met for the pH and electrical conductivity, in the case of air emissions is violated with on the NO2 and SO2. The results, show that the stage with the greatest contribution is concentrated in the generation area, and the most aggressive products to the environment are the consumption of fuel oil (human health 80 %, ecosystem 53 % and natural resources 95 %) and the residual product of the cleaning of the exploitation materials (35 % in the case of the ecosystem).

SummaryThe article presents an assessment of the Life Cycle Assessment (LCA) and pointed out its advantages in the analysis of the environmental impact of electricity generation. The article also points to the direction of development of the Polish energy sector and pointed out the need to determine the environmental risks associated with the production of electricity. The use of coal and lignite as the primary fuel causes a significant burden on the environment. An analysis by the method of LCA based on data obtained from two Polish power plants. The results were compared and identified the cause of the existing differences in the results obtained. The article sets out the actions that contributed to reduce the negative impact on the environment, taking place during the production of electricity.

Decarbonization of electricity generation can support climate-change mitigation and presents an opportunity to address pollution resulting from fossil-fuel combustion. Generally, renewable technologies require higher initial investments in infrastructure than fossil-based power systems. To assess the tradeoffs of increased up-front emissions and reduced operational emissions, we present, to our knowledge, the first global, integrated life-cycle assessment (LCA) of long-term, wide-scale implementation of electricity generation from renewable sources (i.e., photovoltaic and solar thermal, wind, and hydropower) and of carbon dioxide capture and storage for fossil power generation. We compare emissions causing particulate matter exposure, freshwater ecotoxicity, freshwater eutrophication, and climate change for the climate-change-mitigation (BLUE Map) and business-as-usual (Baseline) scenarios of the International Energy Agency up to 2050. We use a vintage stock model to conduct an LCA of newly installed capacity year-by-year for each region, thus accounting for changes in the energy mix used to manufacture future power plants. Under the Baseline scenario, emissions of air and water pollutants more than double whereas the low-carbon technologies introduced in the BLUE Map scenario allow a doubling of electricity supply while stabilizing or even reducing pollution. Material requirements per unit generation for low-carbon technologies can be higher than for conventional fossil generation: 11–40 times more copper for photovoltaic systems and 6–14 times more iron for wind power plants. However, only two years of current global copper and one year of iron production will suffice to build a low-carbon energy system capable of supplying the world's electricity needs in 2050.

Abstract Purpose: This study evaluates the environmental efficiency of coal-based electricity generation in India. The study further proposes a new paradigm of life cycle assessment model named CEEPA - Coal Electricity Environmental Performance Assessment (CEEPA). Methods: Life cycle assessment methodology has been used to quantify the impacts of electricity generation from coal. An emission revision model based on pollution and waste produced and its effect categories were proposed after an analytical comparison between three coal-fired thermal power plants in different regions of the country.ReCiPe method was used to conduct the assessment in this study. Software SimaPro was used for LCA analysis. The study was carried out “from cradle to gate” and the functional unit was 1 KWh electricity at the consumer levelResults: The total Global Warming Potential (GWP) values for the three power plants (PP1, PP2 & PP3) are 1,100 g CO2eq/kWh, 1,287 g CO2eq/kWh and 898 g CO2eq/kWh respectively. PP1, PP2 uses Indian coal for electricity generation which is supplied domestically and later sent to the grid, whereas PP3 uses Indonesian coal.Conclusion: The evaluation performed in this study illustrate the latest environmental assessment situation for various technologies in power generation. It also provides an opportunity to suggest areas for possible improvements in the existing electricity generation system based on the quality and quantity of coal used. The empirical findings indicate that the production of coal-based electricity generation has a substantial effect on the use of natural resources, the environment and human health. The implementation of high-efficiency low emission coal-fired power plants is the first step along a pathway to near-zero emissions from coal with carbon capture, use, and storage.
