“…despite the increased usage and demand of fossil energy caused by the epileptic power supply. Alternately, renewable energy sources are employed in addition to conventional energy sources; yet, even if they contribute significantly to the generation of energy in several developed countries, they still do not dominate the energy sector [3].…”

Fossil fuels (crude oil, natural gas, coal, and lignite) have historically been Nigeria's main energy source. Unfortunately, all of these factors combined with additional factors—including an increase in industrial activity, an increase in national population, and worldwide climate changes—could no longer support us. As a result, our houses and businesses now face significant energy demands. There must be a different source of energy that is not exhaustible in order to keep up with the rush. Given that Nigeria is a resource-rich nation, the article aims to provide an overview of renewable energy, list its benefits and drawbacks, and make recommendations for how to use it more effectively in order to compete favorably with other nations.

“…Основною перевагою використання подібних джерел являється значне скорочення викидів шкідливих речовин в атмосферу на відміну від традиційних джерел, які у процесі генерації використовують викопне паливо. Попри це ВДЕ мають значну кількість недоліків, серед яких: залежність вихідної потужності від погодних умов; низька щільність потоку енергії первинного носія; відносно висока вартість електроенергії [1].…”

The article considers the method of evaluating the parameters of equivalent schemes of solar panels using data provided by their manufacturers. The technique involves the use of a digitized volt-ampere characteristic of the solar panel and standard test conditions parameters (STC) to estimate the numerical derivatives at the points of short and open circuit. Digitizing the volt-ampere characteristic introduces some error, which significantly affects the accuracy of determining numerical derivatives. To solve this problem, it is advisable to average the values of the derivatives. It was found that it is sufficient to take 20-25% of the first points and 8-15% of the last points of the digitized curve. In this case, to estimate the value of the derivative at the point of short circuit, it is advisable to use linear fit, and at the point of open circuit – quadratic fit. The peculiarities of using the obtained formulas and the block diagram of the algorithm that implements this technique were also given. A fixed point algorithm is used to solve the transcendental equation of the external characteristic of the solar panel. It was found that in some cases this numerical method may not convergences near the open circuit point. To solve this problem, in the proposed to use the relaxation method. This increases the required number of iterations, but guarantees the convergence of numerical method. The block diagram of the simple iteration algorithm using the relaxation method is given. Modeling the developed technique, one- and two-diode solar panel replacement schemes were used on the example of KC200GT and ST40 solar panels. A comparative analysis of these schemes showed that a single-diode circuit is more relevant, because its use simplifies calculations and eliminates the need for a number of assumptions. The accuracy of the approximation provided by the single-diode circuit is proportional to the accuracy of the two-diode circuit. A comparative analysis of the developed methodology with other works was performed. The results indicate that the proposed algorithm provides the best approximation accuracy among the considered works. For monocrystalline solar panels, the average standard error is 7 times less and the modulus of relative error - 4 times. For polycrystalline panels, the average standard error is 1.5 times less, and the modulus of relative error is 1.75 times. For polycrystalline panels, the approximation error increases due to a non-unit value of the ideality factor for this manufacturing technology of the solar panels.

“…Therefore, the Agreement could lead to an increase in R&D expenses due to the need for competitive advantages over their direct competitors. The Agreement could affect the intensity of R&D through its imposition of limits on carbon dioxide emissions and its expansion renewable energy consumption, with more advantages than disadvantages (Maradin, 2021). According to Wei et al (2016), there should be 3.9 trillion dollars invested in renewable energy by 2030.…”

European Union countries signed the 2030 Climate and Energy Framework Agreement on October 24, 2014. This framework brings with it changes in the expectations of energy consumers and producers that has opened new avenues of research. Because the 2030 Agreement imposed targets to be achieved by 2030, energy companies could increase their R&D expenditures as they search for increased efficiency through a reduction of carbon dioxide emissions and stronger base in renewable sources that promotes innovation. In addition, the risks that arise from climate change can compromise the successful achievement of the targets, such as 27% renewable energy consumption, reduction in emissions of carbon dioxide by at least 40% and to improve energy efficiency. In this study, I conduct an evaluation of the behavior of R&D intensity in this sector. It analyze the behavior of companies related to the electricity sector in two different moments, before and after the 2030 Agreement, by using panel data and comparing the listed companies with headquarters in European Union countries with companies headquartered elsewhere in Europe. The results show that the 2030 Agreement had no effect on R&D intensity in companies in the electricity sector in the countries of the European Union.
