“…Other research analyzed the GHG emissions changes from road transport in Spain during the period from 1990 to 2010, showing that Spain's economic growth has been closely linked to the increase in GHG emissions, and only decreased during the economic crisis [52]. Moreover, changes in emission inventories for different production sectors (affected during financial crisis) has revealed some strategies to reduce future emissions [20,[51][52][53][54]. Other studies have revealed that emissions only decreased during financial crises, even if they increased after those financial crises [18,21,49,55].…”

This work studied the emission changes and their economic effects during the Argentina’s COVID-19 pandemic lockdown. We have analyzed the atmospheric emissions of the main greenhouse gases (GHG: CO2, CH4, and N2O) and other pollutants (NOx, CO, NMVOC, SO2, PM10, PM2.5, and BC) from various sectors such as private road transport, freight, public transport, agriculture machines, thermal power plants, residential, commercial, and governmental from January 2005 to April 2020. We focused on the months with the greatest restrictions of COVID-19 pandemic in Argentina (March and April 2020). The results show emissions reduction up to 37% for PM10, PM2.5, and BC, consistent with observed from satellite images and up to 160% for NOx, CO, NMVOC, and SOx. However, the residential sector has increased their emissions by 8% for the same period. As a consequence, 3337 Gg of CO2eq of GHG emissions were reduced, corresponding to a 20% reduction compared to the same period in 2019. Besides, a 26% reduction in gross domestic product (GDP) was observed due to the COVID-19 pandemic. Our results show that each Tg of GHG reduction was associated to a 0.16% reduction of the GDP from the analyzed sectors. Thus, without a voluntary reduction in consumption associated to significant cultural and technological changes, reduction in GHG would still be associated with deepening inequalities and asymmetries between high and low consumption sectors (i.e., with better (lesser) education, health, and job opportunities), even within countries and cities.

“…Current energy sources, including oil, gas, coal, and nuclear power, are exhaustible. Energy consumption increases at an alarming rate exacerbating the social and environmental impacts and accelerating depletion [1]. In the coming future, therefore, we are expected to focus more on renewable energy sources.…”

Advanced Study of the Parabolic Trough Collector Using Aluminum (III) Oxide Seal

Solar energy is the main source of all sorts of energy present in nature, i.e. all energy produced from it. So the direct use of solar energy as a useful energy is very important. There are numerous solar thermal projects in which the concentrated type collector heats up to 100 to 400 degrees Celsius. It is used in a wide range of applications, including power generation, industrial steam generation and hot water supply. Parabolic trough collector is chosen for steam production, since high temperatures can be achieved. The temperature of the inlet and outlet water, the mass flow rate, the usable heat gain and also the thermal efficiency of the collector are calculated. Theoretical values for heat loss of vacuum as the annulus gas is measured and compared with other values for heat loss of air as the annulus gas. In order to help preserve the vacuum within the annulus gap, a substitute glass-metal seal was created. The seal helped increased the heat loss and thereby improve the overall efficiency of the collector. It can be deduced from the band structure and density of the states of Al2O3 and is an outstanding insulator content. In addition, the assessment of the absorption coefficient showed a low energy range of 5.34 eV to 11.88 eV, with a median value of 11.50 eV and 11.88 eV respectively for parallel and perpendicular polarizations.

“…La demanda energética mundial depende actualmente en gran medida de los combustibles fósiles (petróleo, carbón y gas natural). La extracción y el consumo de estos combustibles tienen un impacto negativo en el medio ambiente, provocando un aumento en las emisiones de Gases de Efecto Invernadero (GEI) [1], [2], [3].…”

El impacto negativo al ambiente por la explotación y generación de energía a partir de combustibles fósiles impone la necesidad de búsquedas de nuevas fuentes de energías renovables y sustentables. Las Celdas de Combustible Microbianas de Sedimentos (CCM-S) son una tecnología en desarrollo para la producción de bioelectricidad. Se ha demostrado que algunos microorganismos presentes en sedimentos de ambientes fluviales son capaces de producir electrones durante las reacciones bioquímicas de su metabolismo. Uno de los aspectos fundamentales en la eficiencia de una CCM-S son los electrodos del biorreactor. La presente investigación se enfocó en el estudio y demostración estadística de la influencia del diseño del cátodo de una CCM-S sobre la producción de bioelectricidad a partir de sedimentos fluviales. Se diseñaron dos cátodos de una CCM-S no dividida. Los electrodos fueron fabricados de Fibra de Carbono Unidireccional (FCU). El área total del ánodo fue de 81 cm2, los cátodos evaluados tuvieron áreas de 81 cm2 y 40.5 cm2. Se colectaron muestras de sedimentos y agua del Río Culiacán. El volumen total de trabajo fue de 1500 ml. Se estudiaron dos CCM-S, en el primer biorreactor el cátodo fue colocado verticalmente y sumergido en el electrolito de trabajo, mientras el cátodo de la segunda celda fue colocado horizontal y parcialmente sumergido. Se determinó la diferencia de potencial eléctrico producido por ambas celdas durante 40 días y se monitorearon algunos parametros físicos. Los resultados de ambas CCM-S fueron comparados y las distribuciones de voltaje obtenidas fueron caracterizadas estadísticamente empleando el software R. Además se realizó un ANOVA mediante el test de Welch y comparaciones robustas mediante la función Lincon para comprobar la existencia de diferencias significativas entre ambos grupos. Los resultados demostraron que es posible obtener energía eléctrica a partir de los sedimentos fluviales. Se obtuvieron valores máximos de voltaje de 513 mV y 664.7 mV para las celdas 1 y 2, respectivamente, evidenciando que la disposición del cátodo en la celda influye en la energía producida. El estudio estadístico avanzado comprobó que existen diferencias significativas entre las medias de las distribuciones de voltaje de ambas celdas, con un p-value de 0.01 con un nivel de confianza de 95%.
