“…Stream 2: Saturated liquid solution with a higher concentration of LiBr in water. (7) Due to the extensive design possibilities, there are many considerations regarding the steam state in which the refrigerant exits the generator. For this model, we adopt the consideration presented by Wonchala et al [28], where the generator refrigerant outlet temperature is considered to be equal to the equilibrium temperature of the weak solution:…”

“…Solar thermal cooling systems using absorption cooling are so far relatively small technologies, but the market is growing as costs come down. By the end of 2015, an estimated 1350 solar thermal cooling systems had been installed worldwide, of which about 80% were in Europe, mainly in Spain, Germany, and Italy [1,[6][7][8]. Costs for air conditioning by absorption with solar collectors have been reduced by more than half since 2007, largely due to the standardization of equipment, although they have not decreased as rapidly as solar photovoltaics [9,10].…”

A single effect LiBr–H2O absorption refrigeration system coupled with a solar collector and a storage tank was studied to develop an assessment tool using the built-in App Designer in MATLAB®. The model is developed using balances of mass, energy, and species conservation in the components of the absorption cooling system, taking into account the effect of external streams through temperature and pressure drop. The whole system, coupled with the solar energy harvesting arrangement, is modeled for 24 h of operation with changes on an hourly basis based on ambient temperature, cooling system load demand, and hourly solar irradiation, which is measured and recorded by national weather institutes sources. Test through simulations and validation procedures are carried out with acknowledged scientific articles. These show 2.65% of maximum relative error on the energy analysis with respect to cited authors. The environmental conditions used in the study were evaluated in Barranquilla, Colombia, with datasets of the Institute of Hydrology, Meteorology and Environmental Studies (IDEAM), considering multiannual average hourly basis solar irradiation. This allowed the authors to obtain the behavior of the surface temperature of the water in the tank, COP, and exergy efficiency of the system. The simulations also stated the generator as the biggest source of irreversibility with around 45.53% of total exergy destruction in the inner cycle without considering the solar array, in which case the solar array would present the most exergy destruction.

“…In addition, the release of greenhouse gases and other pollutants from these fuels pollutes the atmosphere. Around the world, efforts are being undertaken to lessen this issue and to focus more on generating energy from renewable sources [1][2][3]. Nowadays, wind-energy is widely regarded as a financially feasible way to boost energy production while lowering air pollution and global warming.…”

Energy is essential to the nation's economic growth and to raising the standard of living for its citizens. Following its independence, India invested a great deal of resources in expanding its energy potential. As a result, the nation's capacity for generation has grown significantly. Everyone is aware of the environmental risks associated with traditional energy generating. India has thus been planning the development of environmentally friendly renewable-energy generation via solar, hydroelectric, and wind-energy sources. Renewable-energy has received particular attention, even though the nation primarily generates its energy from natural gas and coal. India ranks fourth among the nations that produce wind power this essay has honestly attempted to provide a brief synopsis of the global and Indian developments in wind-energy from the late 20th century to the present. It also examines the results of some global studies conducted on a range of topics related to this industry. One can get a sense of the current state of the wind-energy development project after reading this document.

“…Having quality, economical, and ecological electrical energy is a current challenge for many countries since it can solve some of humanity's problems and the environment [1]. The expansion of renewable energy sources is a step forward in the sustainable use of available natural resources in different countries [2], [3]. Internationally, several programs have been established as tools to encourage countries to use the potential of renewable natural resources to diversify their energy matrix.…”

<span lang="EN-US">The research analyzes the influence of the average temperature on the performance of specific photovoltaic solar modules under the environmental conditions of the city of Portoviejo, province of Manabí, Ecuador. The research is carried out using the qualitative methodology. Its main objective is to determine the influence of temperature on the energy performance of photovoltaic modules under the region's environmental conditions. Two electrical diagrams with different configurations were designed, which were analyzed and simulated using the MATLAB Simulink software. The results obtained show the direct relationship between the electrical parameters of voltage, current intensity, and power with the temperature value on the surface of the modules. It is concluded that the modules generate a higher value of voltage, electric current intensity, and electric power at a lower temperature, regardless of the level of solar irradiation they receive.</span>
