“…From 2021 to 2022, crops are expected to expand at a 6.58% annual rate, compared to a 5.96% growth rate in the previous year (GOP 2020). Wheat production is reduced when insufficient water is available for its cultivation (Han et al, 2018;Khan et al, 2019;Jiang et al, 2020;Xiong et al, 2020;Bouzidi and Campana, 2021;Hoppert and Einfalt, 2021). Micro-water shed management may assist in dealing with such water shortages (Korai et al, 2021;Chakraborty et al, 2022;Wang et al, 2020).…”

Recently, it has been observed that fossil fuel utilization increased to manage the issue of food insecurity; however, it has increased the risk of environmental degradation and land availability. Therefore, the role of a farmer is to ensure food security (FS). With the assistance of the green revolution (GR), green finance (GF) and green energy have increased manifold. For this purpose, the current study utilized a time-series dataset between 2071 and 2019 to evaluate the relationship between green finance, green energy, and the green revolution with food security. This objective has been considered with modern econometric methods, including the Johansen cointegration model and impulse response. As a result, the Johansen model affirmed cointegration between the green revolution, green finance, and green energy with food security. According to the results, food security will rise by 0.17%, 2.05%, 0.006%, and 0.023%, with a 1% increase in fossil fuel utilization, green finance, improved seeds, and water availability, respectively. Furthermore, based on the diagnostic statistics, the Johansen model’s credibility, stability, and reliability were corrected. In light of these findings and the impulse response function, all relevant factors will favor future food security. Finally, this study suggested that the public and commercial sectors should invest significantly in R&D to produce organic chemicals and agricultural methods that preserve soil fertility and reduce environmental degradation.

“…Photovoltaic water lifting technology has been widely used in pastoral areas, but the differences in solar energy resources and water resources at the construction sites of photovoltaic water lifting have led to poor matching of photovoltaic water lifting power systems, high failure rate, poor stability, and low efficiency of water lifting [2]. This study uses solar energy as water lifting power in pastoral areas, and analyzes the matching characteristics of water pumping flow, photovoltaic system, and the flow characteristics of different operation modes of photovoltaic system, in order to improve the efficiency [3], water output, and reliability of photovoltaic water lifting system, and to improve the assurance rate of water supply in pastoral areas, improve drinking water facilities in pastures, increase the output value of animal husbandry. Also, it aims to provide a technical basis for the flow characteristics of photovoltaic water lifting systems in pastoral areas.…”

In order to clarify the problems of high failure rate, low efficiency, and low outflow rate of PV water pumping stations in pastoral areas due to large differences in resource conditions and poor equipment matching, this study uses the PV water supply model, establishes a pilot site for PV human storage water supply in pastoral areas, carries out research on the relationship between solar energy resources, water supply demand and power system of PV water pumping stations based on group observation tests in the field, and analyzes the PV system. We analyzed the relationship between different tracking operation modes and the amount of solar radiation and water supply flow, and compared the outflow characteristics of fixed type, single-axis tracking type, and double-tracking axis type, in order to explore a kind of PV water pumping station technology suitable for human storage and drinking water in pastoral areas, which can meet the water demand of pastoral water users. The research results show that the single-axis and dual-axis water lifting systems are significantly more efficient than the fixed-support water lifting system, receiving solar radiation at more than 80% of the maximum radiation throughout the day, and lifting water flow at more than 90% of the maximum discharge flow. Compared with the fixed-support PV water lifting system, the radiation of the single-axis PV water lifting system increases by 28.9%, and the daily water output increases by 43%; for the dual-axis PV water lifting system, compared with the single-axis PV water lifting system, the daily radiation of the dual-axis PV water lifting system increased by 4.8% and the daily water output increased by 3.2%; the starting radiation of the PV water lifting system was 256 W/m2.

“…As the share of renewables grows, researchers are beginning to investigate their characteristics in more depth [3]. Of particular interest is their spatial and temporal behavior, as these qualities heavily impact the performance of energy systems [4]-both large-scale, interconnected ones as in Europe [5] and small-scale, off-grid systems supplying power to local communities or, for example, water pumping devices [6].…”

Complementarity and ‘Resource Droughts’ of Solar and Wind Energy in Poland: An ERA5-Based Analysis

et al. 2021

In recent years, Poland has experienced a significant increase in the installed capacity of solar and wind power plants. Renewables are gaining increasing interest not only because of Poland’s obligations to European Union policies, but also because they are becoming cheaper. Wind and solar energy are fairly-well investigated technologies in Poland and new reports are quite frequently added to the existing research works documenting their potential and the issues related to their use. In this article, we analyze the spatial and temporal behavior of solar and wind resources based on reanalysis datasets from ERA5. This reanalysis has been selected because it has appropriate spatial and temporal resolution and fits the field measurements well. The presented analysis focuses only on the availability of energy potential/resources, so characteristics intrinsic to energy conversion (like wind turbine power curve) were not considered. The analysis considered the last 40 years (1980–2019) of available data. The Spearman coefficient of correlation was considered as a complementarity metric, and the Mann–Kendal test was used to assess the statistical significance of trends. The results revealed that: The temporal complementarity between solar and wind resources exists mostly on a seasonal scale and is almost negligible for daily and hourly observations. Moreover, solar and wind resources in joint operation exhibit a smoother availability pattern (assessed based on coefficient of variation). Further findings show that the probability of ‘resource droughts’ (periods when cumulative generation was less than arbitrary threshold) lasting one day is 11.5% for solar resources, 21.3% for wind resources and only 6.2% if both resources are considered in a joint resource evaluation. This situation strongly favors the growth of local hybrid systems, as their combined power output would exhibit lower variability and intermittency, thus decreasing storage demand and/or smoothing power system operation.
