“…Following the second proposal, we should analyse more the situation of the states with the best performance. All in all, it is necessary to evaluate the effect of more factors on RES development: internal energy production, technological development, investment in research and development, foreign dependence, community policies, subsidy policy, industrial know-how, as well as citizens' openness to doing business and protecting environment [64][65][66][67][68][69][70][71][72][73][74][75][76][77][78][79][80].…”

Renewable Energy in Final Energy Consumption and Income in the EU-28 Countries

The deployment of renewable energy sources (RES) is considered to be an important objective for the energy sector in the European Union (EU). The EU Directive adapted in 2009 fixed mandatory national targets for the use of renewable energy in transport as well as for the share of RES in the gross final energy consumption. Contrary to previous studies, this paper does not examine the link between the RES and economic growth but rather focuses on real gross domestic product (GDP) and the implementation of national renewable energy targets. We employ panel data models for the case of the EU-28 countries covering the period between 2007 and 2017 that yield a low and positive relationship between the impact of GDP per capita and the share of RES in the final consumption. Our results show that there is a significant causality only from real GDP per capita to the share of renewable energy in final consumption, marking the potential of developed countries to consume more RES. We list some groups of countries according to these variables using a cluster analysis approach. Starting from the proposed panel data models, we constructed the scenarios for the 2020 for various shares of RES and different EU Member States. Overall, it appears that more attention should be attributed to policy proposals in which funding opportunities would be dependent on the achievements of national targets and economic benefits should be given to countries with very good performance in achieving high shares of renewable energy in their final energy consumption.

“…The massive growth in demand forecasts, estimated by various sources, puts the potentially largest and most significant energy market in the world on track for a massive increase in energy demand over the next few decades. Primary energy demand will rise to 2.1 billion tons by 2020, which will increase global electricity production to about one-third of total global energy consumption by 2030 [26,27]. This estimate has been confirmed to represent about one-fifth of total global spending and is at the forefront of potentially the most ambitious energy growth forecasts in recent years [28].…”

This research tackles effective and functional management practices in energy consumption using advanced technological solutions to mitigate unexpected events. This study specifically focuses on the recent COVID-19 pandemic that led to a reduction in energy consumption and therefore meddled with the project management’s status quo for the energy sources. Moreover, this research analyzes the role of information and communication technology (ICT) solutions in energy management before and after the recent coronavirus pandemic turmoil. This study also examined the role and place of sustainable energy resources in the effective management of energy consumption during the COVID-19 pandemic. The main purpose of this research is to demonstrate how the recent coronavirus pandemic affected energy consumption and energy prices in many countries and how it paved the way for the new ICT in managing energy consumption. This study elaborated a model to show how these changes evolved in selected European Union (EU) Member States. It turns out that adjusted electricity consumption, as well as the average daily spot electricity prices for the baseload power in the EU countries, declined, and this trend is likely to continue in the next years to come. Due to the COVID-19 pandemic, substantial changes in the economy led to reduced office space usage, cutting commuting and business trips, and bringing commercial travel almost to a halt, further shifting the energy balance towards renewable energy sources (RES). Besides, it becomes apparent that ICT solutions used in maintaining and superintending the energy balance are gaining popularity and wide recognition worldwide and will help pave the way towards modern and smart high-renewables grids.

“…gas emissions, noise pollution, risk of water contamination, and environmental pollution [4]. These problems have led to the use of renewable energies for water pumping applications, with solar photovoltaics identified as a reliable and sustainable solution in rural areas of the developing world with high levels of annual irradiation [5], [6]. Several challenges must be faced to maximize the energy utilization and efficiency of pumping systems for irrigation [7] and domestic use [8].…”

Photovoltaic Water Pumping: Comparison Between Direct and Lithium Battery Solutions

et al. 2021

This work presents the conversion of a photovoltaic water pumping system (PVWPS) to its corresponding battery-based solution, while maintaining the components of the PVWPS facility and adding the power converter needed to manage the operation of a lithium-ion battery. A complete analysis of the direct PVWPS is performed based on the values obtained by the monitoring system developed for the installation. The efficiencies and performance ratios of the various elements of the facility are calculated, as well as other relevant factors (such as irradiance thresholds). The dependence of some variables on the solar resource is analyzed to model the system. A similar study is carried out in the battery-based solution and a comparative analysis of the two modes of operation is then performed to find which aspects could be improved in the battery-based solution to increase the pumping time and total daily pumped volume. The results presented demonstrate the benefits of including a battery (reduction in start/stop cycles and improved performance on cloudy days). Aspects that can be improved to make the battery-based solution more efficient and achieve better results are suggested.INDEX TERMS Photovoltaic water pumping systems, lithium batteries, battery-based pumping, water pumping, stand-alone photovoltaic system, sustainable development goals.
