The use of alternative fuels in diesel engines has been the subject of research that seeks new fuels to expand the energy matrix. The aim of this study was to evaluate the performance of the stationary engine with the use of mixtures of biodiesel from soybean and castor bean added to diesel (S500) in two proportions (25% and 40%), evaluating the torque, effective power observed and specific consumption. The five biodiesel mixtures of soybean (S) and castor bean (C) analyzed were: S100C0, S75C25, S50C50, S25C75 and S0C100, which were added to the diesel in proportions B25 and B40, totaling ten treatments, plus the control with diesel S500 (B7). The stationary engine was subjected to the rotations of 3000, 2700, 2400, 2100, 1800 and 1500 rpm. The performance of the engine was similar for all biodiesel mixtures of soybean and castor bean, and commercial diesel (B7). The B40 S100C0 and B40 S75C25 provide better performance in terms of effective power observed and torque at 2700 rpm. The highest effective maximum power (3000 rpm) was obtained with the use of B7 diesel. In the lower rotations, it was possible to identify a similar performance result of the biodiesel mixtures with the B7, in addition to providing better torque and consumption performance compared to the commercial diesel.

O segmento de papel e celulose é um dos mais importantes segmentos industriais eletrointensivos do país. As unidades industriais são intensivas tanto no uso de energia térmica quanto elétrica, nas diversas etapas da produção de celulose e posteriormente na fabricação de papel. Grande parte dessa demanda energética é suprida por combustíveis provenientes do próprio processo, como o licor negro e biomassa florestal, entretanto, em muitos casos as unidades não são autossuficientes em energia. A matriz energética dessa indústria se baseou, inicialmente, no suprimento através do óleo combustível, abundante e barato. Todavia, com as crises de petróleo e a recessão estabelecida no país na segunda metade da década de 70, ocorreram rápidas e significativas mudanças, motivadas pelo incentivo do uso do licor negro em caldeiras de recuperação química. O gás natural, com a exploração das bacias de Santos e Campos, bem como com a construção do Gasoduto Brasil-Bolívia, também se tornou uma boa opção energética para a substituição do óleo combustível. Nesse trabalho buscou-se analisar as possíveis trajetórias da matriz energética da indústria de papel e celulose brasileira, no horizonte de curto e médio prazo, assim como identificar os fatores de transformação no histórico da matriz e definir tendências para o mercado de combustíveis e para o desenvolvimento tecnológico associado ao uso dos produtos energéticos no setor. As principais mudanças na participação dos insumos energéticos dessa indústria se deveram não somente pela relação de preço, mas também associadas às políticas setoriais, como o incentivo à autoprodução de energia e aproveitamento de subprodutos para diminuir a dependência externa de combustíveis e energia elétrica. Investimentos no aumento de eficiência dos processos e a adoção de tecnologias avançadas na geração de energia levarão à menor dependência externa de combustíveis e energia elétrica. A elevação dos preços dos combustíveis fósseis, associada à formação pouco transparente do preço em mercados verticalizados, tem proporcionado um incentivo à ampliação do uso de biomassa na matriz energética. Além disso, diante das incertezas sobre a demanda futura de celulose,a competitividade da indústria de papel e celulose estará vinculada à diversidade nos produtos gerados, aplicando o conceito de biorrefinarias florestais e realizando os múltiplos aproveitamentos da biomassa em rotas tecnológicas distintas. Pulp and Paper is one of the most important energy intensity industries in Brazil. Industrial units are intensive in both use of thermal and electrical energy, in many processes during pulp and papermaking manufacturing. Much of this energy demand is supplied by fuel from process itself, such as black liquor and forest biomass; however, in many cases units are not self-sufficient in electricity. Initially, Pulp and Paper energy matrix was based on fuel oil supply, abundant and cheap. However, with oil crisis and Brazilian recession established in the second half of 70s, there were fast and significant changes, motivated by incentives of black liquor utilization in chemical recovery boilers. Natural gas, explored in Santos and Campos Basins, and also with the construction of Bolivia-Brazil gas pipeline, has become a good energy option for replacement of fuel oil supply. In this paper we have analyzed possible trajectories for Brazilian Pulp and Paper energy matrix, in a short and medium term, even as identified changing factors in matrix historical data and defined trends for fuel market and technological development associated with energy usage. Main changes in Pulp and Paper energy inputs share were explained not only by the price ratio, but also to sectorial policies, as self-generation incentives and utilization of byproducts to reduce dependence of external supply of fuel and electricity. Investments to increase process efficiency and adoption of advanced technologies in power generation will lead to less dependence on external supply. Rising fossil fuel prices, associated with anon-transparent price formation in vertical markets, has motivated an increase of biomass use in energy matrix. Moreover, given the uncertainty about pulp future demand and prices, Pulp and Paper competitiveness is related to products diversity, by applying forest biorefineries concept and performing biomass multiple utilizations in different technological routes.

The energy from sugarcane is one of the most important in Brazil’s energy matrix and the efficiency of extraction and processing is fully dependent on the quality of the raw material. The soil present in sugarcane was investigate here as a factor that can affect the production of energy. Chemical elements (Fe, Hf, Sc and Th) determined by instrumental neutron activation analysis were used for tracing soil in sugarcane and its derived bagasse. The lower calorific value (LCV) of bagasse demonstrated a good negative correlation (r = −0.9727) with the ash content of the bagasse, which in turn was positively correlated to the amount of soil in the sugarcane. Therefore, the presence of soil reduces the production of energy from burning bagasse. The proportion of loss in the LCV was just slightly higher than the soil content, i.e. for an soil content of 10 % a reduction of 12.7 % was observed in the LCV.

Considered the best substitute for diesel, biodiesel can be blended with diesel in any ratio, bringing lots of environmental, economic and social advantages. Brazilian law Nº 11097/2005, proposes the introduction of biodiesel in to the Brazilian energy matrix, mixed with diesel at a minimum percentage of 2%. For consumers and sellers to be sure that the commercialized mixture of biodiesel:diesel contains the correct percentage, it is necessary to develop analytical methodologies to quantify the amount of biodiesel added. This work presents a fast, low-cost and simple methodology to determine the biodiesel proportion in mixtures of biodiesel:diesel, based on infrared spectroscopy.

At present, just 40% of Nigeria’s populace is associated with the energy matrix, while power supply challenges are capable around 60% of the time. In the best-case scenario, the regular everyday power supply in Nigeria is assessed at four hours, albeit a few days can pass by with no force by any means. Neither force cuts nor reclamations are reported; prompting requires a heap shedding plan during the COVID-19 lockdowns to help reasonable conveyance and consistency. To address this issue, this paper proposes energy harvesting technologies to the epileptics power supply in Nigeria. The technology was chosen as proven efficient and reliable in many studies as an alternative and reliable power generation source. It is also largely maintenance-free and environmentally friendly, and powers hardware where there are no ordinary force sources, and ultimately, it wipes out the requirement for continuous battery substitutions and running wires to end applications. The paper was written in sections: Introduction; Power Supply in Nigeria; Current Situation in the Power Sector; Overview of Energy Harvesting Technology; Application Area of Energy Harvesting; and Solution to Epileptic Power Supply in Nigeria. Lastly, a concise conclusion and a list of relevant references were presented.

This paper explores how Turkey’s politics and economy are affected by changes in global energy. To define which are the most relevant developments, the paper opens with an overview of the country's economic landscape. This analysis illustrates that energy, being the key driver behind its large current account deficit, represents a major point of vulnerability for the country. On this basis, the paper illustrates Turkey's energy matrix, an analysis that outlines the rising role of gas in the country's energy sector, both under the internal (i.e. growing share of the mix) and external (i.e. the country's potential role as regional gas hub) points of view. Finally, these issues are discussed with the aim of assessing the prospects for Turkey to turn gas into a geopolitical and economic asset for the country.

It has been very significant to visualize time series big data. In the paper we shall discuss a new analysis method called "statistical shape analysis" or "geometry driven statistics" on time series statistical data in economics. In the paper, we analyse the agriculture, value added and industry, value added (percentage of GDP) changes from 2000 to 2010 in Asia. We handle the data as a set of landmarks on a two-dimensional image to see the deformation using the principal components. The point of the analysis method is the principal components of the given formation which are eigenvectors of its bending energy matrix. The local deformation can be expressed as the set of non-Affine transformations. The transformations give us information about the local differences between in 2000 and in 2010. Because the non-Affine transformation can be decomposed into a set of partial warps, we present the partial warps visually. The statistical shape analysis is widely used in biology but, in economics, no application can be found. In the paper, we investigate its potential to analyse the economic data.

The global energy production reflects an excessive percentage of non-renewable energy. Therefore, a great volume of investment on renewable energy became a serious matter in order to mitigate the damage caused by the consumption of energy from fossil sources. On the other hand, Brazil’s oil companies are living a decisive moment in terms of investments in energy bases, because there is a great demand for capital resources to develop the latest discoveries of enormous non-renewable supplies. In this context, this paper describes the impact of the projects announced by the oil and gas industries in the Brazilian energy matrix. The data comes from the plans presented by the major oil companies that operate in Brazil basins, mainly in pre-salt region, and from reports published by EPE (Energy Research Company – Government of Brazil). This work involves projections from 2011 to 2020 and it was made assuming three global economic scenarios: recession, stability and economic growth. Projections are treated in a comprehensive knowledge by a simple econometric model and based on the investments announced by the oil industry of the country. Studies take into account the fossil and renewable energy projections under assumptions from the Ten Year Plan for Energy Expansion in 2020 produced by the National Council for Energy Policy (CNPE, in the Portuguese-language acronym). The results indicate viable economic projects in the renewable energy for the Brazilian oil and gas companies (energy corporations), primarily biofuels, wind and solar power, in the expense of some oil production projects in their portfolios. Brazil is experiencing a great time to develop the renewable energy sources that is made by other countries and if these changes accelerate, it will be the potential to improve its economy by creating millions of jobs. As main conclusion, the decisions on investment in renewable energy with capital acquired from the pre-salt projects will determine the future of the Brazilian energy matrix. The main goal of this paper is to indicate a transition to a cleaner energy matrix considering an alternative investment plan, and show some fundamental concepts to illustrate how the renewable energy can be important for the oil and gas companies’ subsistence in the next generations.

This paper reports a theoretical calculation of spin-Hamiltonian parameters ( g factors g // , g ⊥ and hyperfine structure constants 147 A // , 147 A ⊥ , 149 A // , 149 A ⊥ ) for 147 Sm 3+ and 149 Sm 3+ isotopes in the trigonal La 3+ site of La 2 Mg 3 (NO 3 ) 12 ·24H 2 O crystal from a diagonalization (of energy matrix) method. In the method, the Hamiltonian concerning the energy matrix includes the Zeeman and hyperfine interaction terms and so there is no perturbation calculation in it. The crystal-field parameters in the energy matrix are calculated using the superposition model, in which the structural data of 12-fold coordinated site rather than those of the incorrect 6-fold coordinated site given in the previous paper are applied. The calculated results are in reasonable agreement with the experimental results. The results are discussed.

Este artigo discute a realidade energética no âmbito dos BRICS, com especial atenção às energias renováveis. Sob tal perspectiva, o Brasil emerge com papel destacado na coalizão, sendo considerado um dos países mais descarbonizados do mundo, pioneiro em bioenergia e um dos líderes globais em geração eólica e hidrelétrica. Por outro lado, o carvão ocupa um espaço considerável na matriz energética da Áfri ca do Su l, China e Índia. Ademais, o bloco ainda conta com o maior produtor de petróleo cru do mundo: a Rússia. Levando em consideração as potencialidades e os desafios de cada país no tocante ao assunto, esta pesquisa se estrutura em torno de dois eixos principais: avaliar como as fontes renováveis permeiam os acordos bilaterais firmados pelo Brasil na área de energia com os “RICS”; e entender como o debate está caracterizado nas declarações conjuntas das cúpulas do bloco. A metodologia utilizada envolveu a construção de um banco de dados original, bem como a aplicação de técnicas de estatística descritiva e análise de conteúdo. Os resultados apontam que China e Rússia dominam, de longe, a pauta ene rg&eacut e;tica bilateral do Brasil com os RICS e que o governo Lula foi, desde a redemocratização, o mais ativo em termos de quantidades de atos internacionais referentes à energia firmados com esses parceiros. Os achados também indicam alguns pontos de intersecção entre as pautas bilaterais e as posições conjuntas adotadas nas declarações de cúpula, a despeito de não ter havido um aumento dos acordos sobre energia após o estabelecimento dos BRICS., This paper discusses the energy reality within the BRICS, with special attention to renewable energies. From this perspective, Brazil emerges with a prominent role in the coalition, being considered one of the most decarbonized countries in the world, a pioneer in bioenergy and one of the global leaders in wind andhydroelectric generation. On the other hand, coal occupies a considerable space in the energy matrix of South Africa, China and India. In addition, the has the largest crude oil producer in the world: Russia. Taking into consideration the potential and challenges of each country regarding this matter, this research is structured around two main axes: to evaluate how renewable sources permeate the bilateral agreements signed by Brazil in the area of energy with the “RICS”; and understand how the debate is characterized in the summits joint declarations. The methodology used involved the construction of an original database, as well as the application of descriptive statistics and content analysis techniques. The results indicate that China and Russia dominate Brazil's bilateral energy agenda with the RICS and that the Lula administration has been, since the redemocratization, the most active in terms of the number of International energy acts signed with these partners. The findings also indicate some points of intersection between the bilateral agenda and the joint positions adopted in the summit declarations, although there was no increase in energy agreements after the establishment of the BRICS.

An on-load tap changer (OLTC) is one of the most error-prone parts in the transformer. The stability of the entire power system will be greatly threatened if the OLTC fails. It is necessary to diagnose the mechanical fault of OLTCs. At the same time, the mechanical fault signals are not easy to collect during practical application. It is desirable to have indicators that help to access the condition of the OLTC with a small number of fault samples. This paper describes a strategy for distinguishing different mechanical diagnostics of OLTCs based on dynamic time warping. By synchronization, framing, and Fourier transform, the signal can be represented by an energy matrix, which can be used to distinguish different conditions of the OLTCs and shows the severities of the fault. Some simulated experiments are designed and in order to make the simulations close to reality, all experiments are taken in a tank which is filled with transformer oil. These experiments demonstrate that the proposed approach can effectively diagnose different OLTC faults under different fault severities.

Energy is a fundamental element for the development of societies, with energy transformation from renewable sources a challenging theme throughout the world. In Brazil, the energy matrix is composed mainly of non-renewable sources such as petroleum and its derivatives, but the transformation for electricity supply is carried out mainly by hydroelectric plants. This paper presents data from the National Energy Balance between the years 2011 to 2016, regarding the internal supply of energy, as well as the sectors that use it as their main source of electricity, allowing a better visualization of the national scenario. In view of the problem, the main objective is to present possibilities for the production of energy by ocean waves, a concept already studied in developed countries. For example, three tested converter devices are considered: one in Norway and two in Denmark. Considering this possibility from the power of the ocean waves in the world, as well as the climatic, geographical and wave characteristics of Brazil, this work indicates the possibility of a significant increase in the Brazilian energy matrix through the use of the energy of the ocean waves. However, there is a growing need to foster research and development projects in this area, so that this alternative source of energy will become viable.

The improvement energy conservation system has been challenging and interesting for small and medium enterprises (SME) of Thailand. This paper presents energy conservation in the knife industry used energy management and brainstorming workshop. Methodology applied energy matrix management and collaboration with community. The results show that this research can be reduce the energy consumption and enhancement of machinery. Moreover, the participant community induced to sustainable development.

This paper proposes as a principal objective shows that the situation of oil prices in the initial four months of 2020 in Colombia and in general in medium oil producing countries implies the opportunity to rethink the production structure and the energy matrix too. The causes of this drop in oil prices are presented and discussed, such as world demand, pressured in the months of March and April by the COVID-19 situation, the self-sufficiency of the United States and the energy transition in China. Some statistical data are then presented to reinforce the opportunity argument represented by the drop in prices of both fossil and alternative energy. At the same time, the environmental implications of exploiting unconventional oil reserves are questioned for the need of exploitation with non-conventional techniques such as fracking. In the end, a return to development banks is proposed to promote both economic diversification and the energy transition. &nbsp

Fossil fuels still prevail over other energy sources in the world’s consumption energy matrix. Thus, oil transportation and operations over maritime routes have been in high demand for a long time. Although oil spill accidents caused by these activities have reduced significantly over the last few decades, they still cause great concern. From this perspective, this paper presents simulation analyses of oil spill case studies using TELEMAC-3D hydrodynamic model coupled with an oil model. Hence a location susceptible to such accidents was selected and three real oil spills were simulated, for each of which there were official technical monitoring reports available. The obtained results contribute to the knowledge of oil pollution susceptibility in environmentally sensitive areas, as well as provide information concerning oil slick behaviour. Additionally, similarities between the modelled results and the technical reports were confirmed. These findings are useful for contingency planning and responding to these probable accidents.

This paper aims to address the necessity of the international community regarding the reformulation of energy policies after the oil shock (70's) to enable the diversification of its energy matrix and foster prosperous relations in this area. Thus, will approach the Brazilian energy policy through the concept of energy security that, although is often confused with energy independence, has a broader scope of analysis that overflows to a wide variety of sectors and dimensions beyond energy itself.

This paper reports the unified calculations of the optical band positions and spin-Hamiltonian parameters (g factors g//, g⊥ and zero-field splitting D) for two trigonal Cr3+ centers in Cs2NaGaF6: Cr3+ crystals. The calculations use the complete diagonalization of energy matrix method based on the two-spin-orbit-parameter model which takes account of the contributions from both the spin-orbit parameter of central dn ion (in the conventional crystal-field theory) and that of ligands. The calculated results are rationally coincident with the experimental values. The slight local lattice distortions in both Cr3+ centers are also estimated from the calculations and the causes are discussed.

Concentrated Solar Energy (CSP) has been gaining ground in the world's energy matrix, given that it is a source clean, renewable and safe. Considering the potential of the Brazilian Northeast in heliothermic energy generation, this paper presents the main factors for the feasibility study of a CSP plant of central tower in three cities of the state of Rio Grande do Norte: Apodi, Caico and Mossoro. Using System Advisor Model (SAM) software as the main tool and the Gemasolar plant as a reference to for the initial design parameters, the results showed that Apodi was the most favorable for the plant's implementation of 19.9 MW, with solar multiple of 2.1, generating an optimized Levelized Cost of Electricity of 15.28 ¢/kWh and capacity factor of 61.5 %.

In the last few years there has been an increasing incorporation of solar photovoltaic generation in the Uruguayan energy matrix. This paper focuses on the subject of photovoltaic microgeneration connected in the low-voltage network. The aim of this work is to establish an adequate methodology to estimate microgeneration potential in Uruguay. Towards that end, simulations were carried out in softwares Power Factory and SimSEE in order to evaluate the impact this form of generation has on the Uruguayan Electrical System, regarding both technical and economical aspects.

Renewable energy sources have a key role in the energy mix because of their impact on Greenhouse Gases emissions, national energy security, among others. In this context, this paper examines comparatively, under a systemic and multidimensional approach, the policies that have introduced renewable energy in the electric power generation in Argentina, Brazil and Uruguay. The results show that Argentina has had a low performance in these policies in comparison to Brazil and Uruguay, due to failures in the promotion mechanisms and institutional designs., Las fuentes renovables de energía poseen un rol esencial en el mix energético de un país, por su impacto en las emisiones de gases de efecto invernadero, la seguridad energética, entre otros. En este contexto, el objetivo de este artículo es analizar comparativamente, bajo un abordaje sistémico y multidimensional, las políticas que se han desarrollado para promover las energías renovables en la generación eléctrica en la región sudamericana, en particular en Argentina, Brasil, y Uruguay. Los resultados muestran que Argentina ha tenido un desempeño muy pobre comparado con Brasil y Uruguay, debido a la existencia de fallas en los marcos de promoción y en los diseños institucionales.

This paper provides empirical evidence of a long-run environmental Kuznets curve (EKC) for Ecuador from 1971 to 2011. Using the autoregressive distributed lag bounds testing approach, we do not just estimate the effect of economic growth on CO2 emissions but also the effect of energy consumption on this one. The effects of all variables have the expected signs. In addition, we test for Granger causality among the variables using an error correction model. Only GDP granger causes energy consumption in the short-run. The results have several policy implications that are consistent with the recent environmental policy of the government

This paper aims to show the current context of Small Hydro Power Plants (SHPs) in Brazil, presenting and discussing the institutional acts, regulations for growth of the SHP, public and private policies for the sector and growth prospects. After the restructuring of the Brazilian electricity sector, a series of laws, decrees and resolutions were developed with the purpose of regulating the sector in favor of SHPs. In 2001, the number of SHPs in Brazil was 303 with an installed capacity of 855 MW. Over the years, with the changes in the sector and, in 2010, the number of buildings has reached 387, with an installed capacity of 3428 MW. Today, they are 475 SHPs in operation with the generation capacity in the country, around 4799 MW, representing 3.49% of all Brazilian energy matrix. It is estimated that in 2020 the installed capacity will be approximately 6500 MW, but there is more potential available in the country for SHPs, that has great technical and environmental characteristics. It is concluded that more attention must be given by the government policies of the electricity sector to reach in the future the full the potential of SHPs available in Brazil.

Wireless sensor networks have become ubiquitous in the present world of smart technology. With increasing popularity of WSNs in a number of applications brings the major responsibility of making these networks secure. Thus, providing energy efficient security solutions is the need of the hour. In this paper, we propose an energy efficient key pre distribution approach to establish trust among the nodes. This approach takes into account the energy of the nodes and their relative distances from each other while establishing the keys. Moreover, the existing key pre distribution techniques provide very limited or negligible protection against node compromise attack. The proposed scheme can detect node compromise attack without having the need to share a key ring.

In this last decade, the wind energy has achieved a great expansion in the Brazilian energy matrix. Hence, the study and technology development in this area has become essential for academic community and industry. The aim of this paper is to describe the design, construction and commissioning of a 10(kVA) wind energy system (WECS) prototype converter, using permanent magnet synchronous machine. The design of the main components will be described. The first experimental results are shown and briefly analyzed.

At present, the planning agencies define the percentage objectives of renewable generation with the sense of diversifying the energy matrix and achieving technical and economic sustainability. The objectives in the background may pursue different approaches when determining the optimum or mostly recommended percentage. In this sense, the work is focused on determining relevant technical and economic criteria that allow the definition of adequate percentages of large-scale wind generation. In the work, a methodology is developed that considers the construction of electrical studies scenario, including static, dynamic, voltage stability and contingency analysis, and future scenarios of economic operation. The methodology considers different degrees of wind energy input that allows in each case to assess the degree of technical vulnerability of the system and the cost of planning the long-term operation. In particular, to determine the degree of admissibility of wind power input, relevant operational factors of the operation of power systems are identified and valued. Finally, it recognizes the percentage of wind generation that locates the recommended percentage of additional income. The present article is the first of two papers that analyze the “Criteria for determining the percentage of large-scale wind energy to interconnected systems — Part I: Proposal of Methodology”. Additionally, a second article is presented, which uses the methodology applying it for a real case, Part II: Analysis of the Argentine case.

Brazil is recognized for possessing a low carbon-intensive energy matrix, with most of its power being generated from hydroelectricity. Its greenhouse gas emissions profile is dominated by deforestation and land-use change. Despite this characteristic, the country has been committed to the development of carbon capture and geological storage (CCS) research since this technology started to be recognized as a relevant solution for greenhouse gas emission reductions. This development has gained attention recently owing to the beginning of the production of pre-salt reservoirs, which may contain significant amounts of CO2 in the produced fluids. The work has been carried out mostly through the efforts of the academia and industrial enterprises. This paper presents a summary and a brief description of the recent activities being carried out by these sectors, aiming to develop and promote CCS in Brazil.

The complete diagonalisation (of energy matrix) method is applied in this paper to calculate together the optical and electron paramagnetic resonance (EPR) spectral data for Cr3+ ion at the trigonal Ga3+ site of Y3Ga5O12 crystal. The method is founded on the two-spin-orbit-parameter model where in addition to the contributions from the spin-orbit parameter of central dn ion (i.e., one-spin-orbit-parameter model) in the traditional crystal field theory, those from the spin-orbit parameter of ligand ion via covalence effect is also considered. The calculated results propose that by using only four adjustable parameters, the 12 observed spectral data (nine optical band positions and three EPR parameters g//, g⊥ and D) in Y3Ga5O12: Cr3+ are reasonably explained. The impurity-induced local lattice distortion of Cr3+ in Y3Ga5O12 crystal is also estimated through the calculations. The results are discussed.

This work tries to determine whether it is possible to stabilize CO2 emissions under a rapid increase of Gross Domestic Product in a medium term. The paper is an effort to study in detail how changes in the driving forces of the economy affect CO2 emissions. We study the case of Venezuela for the period 1980–2025, using the methodology proposed by Robalino-Lopez et al. (2014, 2013) [1] , [2] , which is based on an extension of the Kaya identity and on a GDP formation approach that includes the effect of renewable energies. We test the environmental Kuznets curve (EKC) [3] hypothesis in a coming future under different economic scenarios considering, therefore, not only past data but also projections for the coming years. We use cointegration techniques [4] and the Jaunky (2011) [5] specification to test the fulfillment of the EKC hypothesis in Venezuela. Our predictions show that Venezuela does not fulfill the EKC hypothesis, but however, the country could be on the way to achieve environmental stabilization in the medium term. This stabilization could be accomplished combining economic growth with increasing use of renewable energy, appropriated changes in the energy matrix, and in the productive sectoral structure.
