Nowadays, establishing clean energy sources is an undeniable need for all territories to reconcile energy and competitiveness objectives with those of security and sustainability. This article shows the main advantages of implementing clean energy sources in the long-term Chilean electrical network. The clean energy considered in this work is based on Renewable Energy (Conventional and Non-Conventional) with the backup of gas or nuclear. Thus, four scenarios are proposed and were simulated for the year 2050, the year assumed for the decommissioning of all coal plants in the country. These scenarios contemplate a high or low penetration of Renewable Energy. Additionally, a reference and realistic scenario for the year 2018 has also been considered to compare to the clean scenarios proposed. The results obtained coincide with the goals of reducing environmental impacts such as global warming emissions and fossil fuel dependence. However, the backup that was chosen for supporting the intermittence of renewable energy may have an important role in the main system considering the expected growth of energy demands in the near future.

Low Carbon Economy

To meet new energy demands and climate targets for 2030, the EU member states and West Balkans countries are requested to introduce the National Energy and Climate Plans (NECP) for the period from 2021 to 2030. That implies implementing clean, affordable and renewable energies to reach a climate-neutral economy by 2050. This will require moving towards the long-term goals set by Power agreements, which means to perform economic transformations to reach broader sustainable development goals. To achieve those goals national long-term strategies in Western Balkan countries jointly with EU strategies have to cover, at least, the following in the coming 30 years: total greenhouse emission reduction, even elimination, to extend feasible socio-economic effects of the decarburization measures, to enable links to other national long-term objectives, to make progress on a low greenhouse gas emission economy by encouraging the use of renewable energy sources to approach the European green plan. All those measures will lead the energy sector in the Western Balkans (WB6) to be organized to function with diversified sources of energy, secure fully functional integrated energy market, the free flow of energy, improve efficiency by reducing needs for energy imports; move to low carbon economy by promoting research and innovations in low carbon and clean energy technologies, which will all lead to extensive implantation of renewable energy sources and control of climate change in the region.

Over 90% of Uganda's power is generated from renewable sources. Standardised Implementation Agreements and Power Purchase Agreements create a long-term relationship between Generating Companies and the state-owned off-taker guaranteed by Government. The COVID-19 pandemic and measures to curb the spread of the virus have triggered the scrutiny and application of force majeure (FM) clauses in these agreements. This article reviews the FM clauses and considers their relevance. The authors submit that FM clauses are a useful commercial tool for achieving energy justice by ensuring the continuity of the project, despite the dire effects of the pandemic. Proposals are made for practical considerations for a post-COVID-19 future which provides the continued pursuit of policy goals of promoting renewable energy sources and increasing access to clean energy, thus accelerating just energy transitions.

To mitigate the problems associated with climate change, the low-carbon economy concept is now being championed around the world in an effort to reduce greenhouse gas emissions and ensure sustainable economic growth. Therefore, to reduce the dependence on traditional energy sources, the Organization for Economic Co-operation and Development (OECD) has been actively promoting the use of renewable energy. Past research has tended to neglect the influence of other pollutants such as fine particulate matter (PM2.5) and sulfur dioxide (SO2) and have mainly been based on static analyses. To make up for these research gaps, this study examined OECD country data from 2010–2014, with labor, fixed assets, new energy, and traditional energy as the inputs, and Gross Domestic Product (GDP), carbon dioxide (CO2), and PM2.5 as the outputs, from which it was found: (1) the overall efficiency of the individual countries varied significantly, with nine countries being found to have efficiencies of 1 for all five years, but many others having efficiencies below 0.2; (2) in countries where there was a need for improvements in traditional energy (which here refers to coal, petroleum and other fossil energy sources), there was also a significant need for improvement in new energy sources (which here refers to clean energy which will produce pollutant emissions and can be directly used for production and life, including resources like nuclear energy and “renewable energy”); (3) countries with poor traditional energy and new energy efficiencies also had poor CO2 and PM2.5 efficiencies; (4) many OECD countries have made progress towards sustainable new energy developments

In addition to the examination of electric power from local renewables, this study has sought the answer to the question of what proportion of vehicles are fueled by environmentally friendly energy saving technologies in the vehicle fleets of Hungarian settlements. Further, the study attempts to shed light on the self-sufficiency of Hungarian settlements with respect to the electricity and transport segments. In our assessments, the performance of small-scale household power plants (SSHPPs) utilizing local renewable energy sources, and small-scale power plants with installed capacities under 0.5 MW, was taken into account, as were the proportions of vehicles operating with partly or completely clean energy sources in the vehicle fleets of the individual settlements. Finally, the composition of the vehicle fleet has been examined in the light of the quantities of renewable electricity generated in the individual settlements, in order to consider whether these settlements are capable of covering the energy needs of their vehicle stocks from local sources. In the light of the results, the changes generated by the incentives and investments introduced over the past ten years can be established and subsequently, the energy policy needs in the future can be assessed. Our study has incorporated energy geography and settlement geography aspects.

The article focuses on the economic and statistical analysis of industries associated with the use of renewable energy sources in several countries. The dynamic development and implementation of technologies based on renewable energy sources (hereinafter RES) is the defining trend of world energy development. The uneven distribution of hydrocarbon reserves, increasing demand of developing countries and environmental risks associated with the production and consumption of fossil resources has led to an increasing interest of many states to this field. Creating low-carbon economies involves the implementation of plans to increase the proportion of clean energy through renewable energy sources, energy efficiency, reduce greenhouse gas emissions. The priority of this sector is a characteristic feature of modern development of developed (USA, EU, Japan) and emerging economies (China, India, Brazil, etc.), as evidenced by the inclusion of the development of this segment in the state energy strategies and the revision of existing approaches to energy security. The analysis of the use of renewable energy, its contribution to value added of countries-producers is of a particular interest. Over the last decade, the share of energy produced from renewable sources in the energy balances of the world's largest economies increased significantly. Every year the number of power generating capacity based on renewable energy is growing, especially, this trend is apparent in China, USA and European Union countries. There is a significant increase in direct investment in renewable energy. The total investment over the past ten years increased by 5.6 times. The most rapidly developing kinds are solar energy and wind power.

The aim of the work is to develop recommendations for Ukraine on setting long-term integrated climate and energy goals and identifying ways to achieve them. The preconditions, main goals and objectives of the European Green Deal, which was presented by the European Commission in December 2019, are analyzed. The European Green Deal is a comprehensive strategy for the transition to a sustainable economy, clean energy and climate neutrality, i.e., zero greenhouse gas emissions, in Europe by 2050. The adoption of this Deal was preceded by several stages of a coherent EU policy in the relevant sectors. Possibilities for renewable energy development within the framework of the European Green Deal are considered. It is determined that preference is given to the production of green electricity, mobilization of the potential of offshore renewable energy, production of biogas and biofuels from biomass of agricultural origin, sustainable use of low-carbon and renewable fuels, including biomass and hydrogen, in hard-to-electricity sectors. In Ukraine, the document that is closest by its contents to the European Green Deal is the draft Concept of green energy transition until 2050 presented in January 2020. The draft Concept states the goal of achieving 70% of renewable energy sources in electricity generation by 2050 and the climate-neutral economy of Ukraine by 2070. It is recommended that this document should be finalized and adopted formally as soon as possible.

The Impact

Abstract BackgroundThe characteristic feature of modern energy sector in the EU is the development of environmentally friendly technologies based on renewable energy sources (RES). The use of alternative and RES contributes to resolving not only energy efficiency issues, but many of the environmental, economic and social problems. RES are also one of the priorities of the world's low carbon policy and reducing CO2 emissions into the atmosphere. Growing electrical energy consumption and increasing integration of RES in power systems have led to new challenges, thus it is required to investigate and properly analyze the impact of integrated RES on the power system as a substitute for fossil fuel resources.ResultsThe aim of the article is to show the possibilities of developing RES in Poland in the context of environmental protection, energy self-sufficiency and international obligations. The depletion of primary energy sources and the increase in emissions of greenhouse gases to the atmosphere forces undertaking certain activities, aimed at seeking substitutes for fossil fuels. According to the author’s analysis, RES are the best and safest substitutes for traditional energy resources such as fossil fuel.ConclusionsThe author examines electricity production mix in EU counties and compares it to Polish energy sector. Taking into consideration the transmission network density in Poland, while energy sector changes its structure and expands, the mix of technologies deployed to produce electricity determines the associated burden on transmission networks. Polish energy sector development in the context of modernization of transmission grid provides an opportunity for investors to prepare the energy system for increasing the share of renewable energy sources. In the process of implementing the appropriate solution, the experiences of other countries that have significantly increased the share of renewable energy in the past could be used. This article presents the main areas of action that may facilitate the further integration of different energy sources in the specific context of Poland's changing energy system. Not all integration options will be important for Poland at the same time.

Energy Mix

AbstractThis paper studies the relationship between the energy mix and the environment using a theoretical framework in which two alternative energy sources are considered: fossil fuels (dirty energy) and renewable energy (clean energy). We find that a positive aggregate productivity shock increases energy consumption and emissions but reduces energy intensity and emissions per unit of output as renewable energy consumption increases, that is, carbon emissions are procyclical but emissions per unit of output are countercyclical. Second, an energy efficiency improvement provokes a “rebound effect” above 100% (the backfire effect), resulting in a rise of pollutant emissions by increasing energy use. Third, a technological improvement in emissions leads to a reduction in emissions per unit of fossil fuel, but also implies a slow-down in the adoption of renewable energy sources. Finally, we consider the case of a decentralized economy in which the government chooses an optimal specific tax on fossil fuel to maximize social welfare. We show that the “second-best” policy is highly effective in correcting the negative effects of the environmental externality and able to almost achive the centralized economy outcome.

Abstract: Electricity production using conventional energy sources is associated with serious environmental problems like emission of pollutants, global warming and social problems. The world’s CO2 emissions are projected to rise from 29.0 billion MT in 2006 to 33.1 billion MT in 2015 and 40.4 billion MT in 2030. This increase in emissions indicates more global warming. The Indian Ministry of New and Renewable Energy (MNRE) has been supporting programs for the development of renewable energy sources which are not only unlimited but environmentally friendly — like biomass, solar, small hydro, wind, etc. If biomass is used sustainably, there is no net carbon emission over the time of a cycle of biomass production.Waste management is an important issue today. To handle the ever growing problem of waste, residents and companies are constantly looking for the best and least expensive methods. Types of waste generated by the Indian Institute of Technology Roorkee (IITR) include kitchen waste, municipal solid waste, sewage waste, and waste cooking oil. By utilizing biodegradable waste out of total waste clean energy can be generated and waste disposal problems solved.DOI: http://dx.doi.org/10.3126/hn.v9i0.7071 Hydro Nepal Vol.9 July 2011 38-43
