Reduction of greenhouse gas emissions from renewable energy technologies in agricultural sectors of Uzbekistan

Abstract

This paper presents the results of calculations to reduce greenhouse gas emissions in agricultural sectors of the Republic of Uzbekistan within the framework of the project: “Sustainable Agriculture Development and Climate Change Mitigation”. The initial data were the characteristics of the implemented installations based on renewable energy sources for the period of 2014-2018. Most of these installations were biogas settings based on the principle of anaerobic fermentation, as well as solar water heating and photovoltaic stations. The calculations were performed according to the “AMS-III.D” and “AMS-I.J” methods by the “Global Environmental Fund” experts. The developed computer programs were applied to calculate the arrival of radiation and the duration of sunshine during the year on the territory of Uzbekistan. According to the calculations, the reduction of greenhouse gas emissions was 1338840.5 tons of CO2 for the indicated period during the operation of installations based on renewable energy sources. Within the framework of this project, the total potential of generating electric energy from biogas settings and solar photovoltaic stations at the amount of 10,424 MWh was estimated.

Study on the effective use of solar and hydro energy for powering agriculture and water management

“…the expression is called the differential equation of rotation of a rigid body around a fixed axis. In equation (17), the moment of inertia Bz is an analogue of the mass m determined from the formula (6), is the effect F acts as the main vector of forces. Usually the turbine is affected by several forces determined by the formula (11), so…”

“…On the other hand, due to their self-sufficiency and low energy prices, solar energy applications in agriculture are expanding for irrigation, lighting, heating, cooling, and drying, which eventually lowers production costs and saves a sizeable amount of investment [15,16]. Solar energy is also getting more cost-effective and efficient, which effectively lowers global warming and makes it a practical answer for climate change issues [17][18][19][20][21]. The inverters are also contained in soundproof casing, and the solar 1142 (2023) 012029 IOP Publishing doi:10.1088/1755-1315/1142/1/012029 2 module has no moving parts.…”

Development of an experimental facility for cooling circulated water of industrial plants

“…The maximum disarrangement was 14 %, which is within the experimental inaccuracy. The elaboration of experimental data to identify the dependence of the height of the three-phase fluidized bed on the air velocity revealed that and is stated by the equation (3) The maximum discrepancy between the experimental and calculated data is . An equation was obtained for the dependence of the dynamic layer height on the rate and density of irrigation, which has the following form:…”

“…In the Republic of Uzbekistan, one of the main areas of the economy is currently receiving a lot of attention: the development of technological equipment for the energy industry that meets modern standards, such as the modernization of cooling systems for circulating water and air conditioning [1,2]. The 2017-2021 Strategy of Actions for the Further Development of the Republic of Uzbekistan emphasized the necessity of reducing the economy's energy and resource intensity through widespread use of energy-saving technologies [3][4][5][6]. To some extent, this research aids in the completion of the regulations' tasks.…”

The role of renewable energy on life expectancy: evidence from method of moments quantile regression based on G-7 countries data

“…Diminishing the effects of climate change and minimizing CO 2 emissions by using alternative energy have positive impacts on the health of humans and have benefits for the surrounding ecosystem. As a result, shifting from fossil fuel consumption to renewable energy increases life expectancy and decreases the expenditure on the treatment of diseases (Anarbaev et al , 2019). On the other, various studies have investigated that health expenditure can promote health indices, such as life expectancy.…”
