Energy is pivotal to the human and capital development of any nation; hence, the ever growing quest to discover reliable and sustainable energy sources. Researches on renewable energy sources ranging from wind, tidal, hydro power and solar energy is on-going; all geared towards providing better electrical energy source. Solar energy, however, holds a very promising future as far as sustainable energy solution is concerned. It is silent, green, with zero negative impact to the globe and no pollution. Unlike the conventional energy sources from fossil fuel, it reduces greatly the impact of global warming and remains endless. The developed solar tracker has two automatic tracking axis for both the zenith daily and the azimuth annually as well as displaying in real-time solar irradiation and tilt angles on the mounted LCD. The self-controlled tracking is achieved by using a MEGA2560 microcontroller board, programmed to read analog values from an array of LDRs, convert them to digital values, compare them and drive the stepper motors in the desired direction until equal light is sensed by alternate LDRs. At this point, the panel is aligned perpendicular to the sun rays to capture the maximum possible energy. A working prototype is successfully designed and constructed. The testing revealed very precise tracking made possible by using micro-stepping modes of the stepper motors. This also gave a very high tracking accuracy of about ±0.0560.

This paper focuses on the use of renewable energy sources in Serbia and the Republic of Srpska and their impact on the environment and climate change. Renewable energy sources used in Serbia are hydropower, solar energy, wind energy, biomass, and biogas. Renewable energy sources used in the Republic of Srpska are hydropower, solar energy, biomass, and biogas. When using hydropower, the formed reservoirs often impact the microclimate of the environment in which they are located. Photothermal and photovoltaic solar radiation conversion installations are mostly stationary, do not emit harmful substances into the environment, and have no impact on climate change. The use of wind turbines has a certain influence on the flow of ambient air. When using biomass and biogas, combustion gases are released into the atmosphere, which has slightly negative impact on climate change. The paper concludes that the use of renewable energy sources in Serbia and the Republic of Srpska has a negligible negative impact on the environment and climate change.

Energy is one of the most important drivers of economic growth, but as the population is increasing, in normal circumstances, in all countries of the world, there is a demand for energy produced from conventional resources. Increasing prices of conventional energy and the negative impact on the environment are two of the main reasons for switching to renewable energy sources (RESs). The aim of the paper is to quantify the impact of the RESs, by type, on the sustainable economic growth at the European Union (EU) level. The research was performed for all 28 EU member states, for a time frame from 2004 to 2017, through a panel autoregressive distributed lag (ARDL) approach and causality analysis. Furthermore, Hausman test was performed on the regression model. By estimating the panel data regression model with random effects, we reveal through our results that RESs, namely wind, solar, biomass, geothermal, and hydropower energy, have a positive influence on economic growth at EU level. Moreover, biomass has the highest impact on economic growth among all RES. In fact, a 1% increase in biomass primary production would impact the economic growth by 0.15%. Based on econometric analysis, our findings suggest that public policies at the EU level should be focused on investment in RESs.

The reliance on non-renewable energy sources is the influence scheming international energy markets and macroeconomic dynamics. Developing economies remain volatile to energy markets due to their heavy reliance on non-renewable energy sources and their low capability to maintain stable energy stock and expensive energy mix, such as Pakistan. The application of autoregressive distributed lag shows that the impact of the energy mix has a significant positive impact on the energy crisis of Pakistan in the long run. Which means that at the macroeconomic perspective only increasing prices of energy have adverse effects, whereas in the short run energy mix shows a significant negative impact on the energy crisis, implying artificial and unsuitable short term ad-hoc adjustments. Therefore, the reluctance in transforming towards the renewable energy sources and ad-hoc adjustments in the formation of the energy mix is a factor of energy crisis in the country.

The Impact

The development of rural electrification is aimed at distributed energy, i.e. availability of autonomous sources of electricity and heat generation. Generation sources can use coal, fuel oil, gas, local and alternative energy sources as fuel and energy resources. This causes additional emissions of pollutants. Prediction of negative impact on the environment depends on the quantity and quality of emissions during the operation of various types of installations that generate electric and thermal energy. The purpose of the study is to select and substantiate the most attractive method for predicting the impact on the environment of generating sources in agricultural production. The widespread introduction of distributed energy using local and renewable energy sources will significantly reduce emissions of pollutants due to a decrease in energy intensity, matching the required load with the capacity of generation sources, using the most energy efficient sources, and widespread introduction of renewable energy sources. In this regard, it is advisable to forecast the impacts by the scenario method considering the implementation of the proposed distributed power supply system. The implementation of measures developed considering the analysis of the forecast of the negative impact on the environment of generating plants in agricultural enterprises will reduce the negative impact on the environment by introducing energy-efficient technologies into the energy balance of the enterprise, as well as increase production by up to 20% and increase sustainability. rural areas.

Environmental pollution, in particular atmospheric pollution, is largely associated with the production of thermal energy. Suspended dusts and chemically aggressive gases generate a significant danger for as well human health as biosphere. In recent years there has been a growing conviction about decisive impact of greenhouse gasses emission generated by the economic and civilizational activity of humanity on global climate changes. Hopes of breaking these adverse trends is connected with the mass use of renewable energy sources or rather so called ecological energy sources, that are relatively less environmentally aggressive. The quantitative comparative assessment of their negative impact on the environment is important in the proper classification of energy sources. Comparing of quantities of emitted suspended dusts and aggressive gases including greenhouse gases is good parameter for evaluation of air pollution. In Polish conditions, atmospheric pollutions are predominated by products of coal combustion. A good indicator of the ecological quality of energy sources is therefore the reduction of emitted harmful substances as a result of coal substitution. In this work examples of ecological effects of geothermal installations have been presented. Geothermal energy is generally considered to be renewable and ecological, while the substitution of coal fuels by hydrocarbons, including natural gas, is more problematic. The comparative analysis performed for a single-family house shows a radical reduction in the emission of suspended dust and chemically aggressive gases associated with replacing the coal furnace by natural gas-fired boiler and reducing the emission of carbon dioxide by half.
