In October 2008, the Brazilian Government announced plans to invest US$212 billion in the construction of nuclear power plants, totaling a joint capacity of 60,000 MW. Apart from this program, officials had already announced the completion of the construction of the nuclear plant Angra III; the construction of large-scale hydroelectric plans in the Amazon and the implantation of natural gas, biomass and coal thermoelectric plants in other regions throughout the country. Each of these projects has ...

The retaking of the ethanol program in the year 2003 as a fuel for light road transportation in Brazil through the introduction of flex fuel vehicles fleet was a good strategy to overcome the difficulties of the ethanol production sector and did work to increase its market share relative to gasoline. This process, however, may cause a future disequilibrium on the food production and on the refining oil derivates structure. In order to analyze the substitution process resultant of the competition ...

The substitution process resultant of the competition between two opponents fighting for the same resource or market is pointed out through a dynamic model derived from biomathematics. A brief description of the origin of the method based on coupled non-linear differential equations (NLDE) is presented. Numerical adherence of the proposed model to explain several substitution phenomena which have occurred in the past is examined. The proposed method is particularly suitable for prospective analysis ...

In recent years, Brazil has made public several oil discoveries located in deep waters, below the salt layer. Discoveries are steadily enhancing national reserves and have brought the country into a new role in the global oil industry. This paper aims at investigating the economic gains that could be expected from a Brazilian oil field in the pre-salt region. Analyses were conducted based on the Libra field, the largest oil discovery in Brazil until now, with approximately 10 billion barrels. The ...

Companies represent essential sources of data for Life Cycle Assessment (LCA). However, management systems and management approaches are rarely informed by LCA data developments, and vice-versa. The present paper focuses on the role of the company in the LCA data collection process. The objective is to investigate the adequacy of the current LCA data quality assessment approach from a management perspective. This is accomplished by applying the ecoinvent Data Quality System (DQS) to a primary LCA ...

Researchers and policymakers are seeking alternatives to oil products. Hydrogen and electricity could be the answer. This review compares both carriers and their technologies across the production chain. This study indicates electricity is more mature and advanced on a large scale. It also presents greater Energy Returns on Investment (EROI) over hydrogen, which portends a viable alternative to oil products. Hydrogen is not adaptable to traditional uses and comes with significant transportation losses, ...

While the short-term economic impacts of extreme weather events are well documented, little is known about their impacts and transmission channels on economic growth in the long run. Using panel data regressions and national shares of people exposed to tropical cyclones and fluvial floods as exogenous predictors, we find output growth losses from severe tropical cyclones and fluvial floods to accumulate to −6.5% and −5.0% over 15 years, respectively. We further observe a strongly non-linear increase ...

European and United States' (U.S.) regulatory schemes mandate the use of biofuels based on estimates of life cycle GHG emissions that indicate their environmental superiority compared with conventional fuels. This paper analyzes the quality of the activity data used in calculating these estimates for Brazilian sugarcane and U.S. corn ethanol, in terms of completeness, reliability, and transparency. The findings demonstrate that it is impossible to determine the completeness of the data because the ...

Such a situation is, from both environmental and economic points of view, neither desirable nor strategic for the country, a signatory to United Nations Framework Convention on Climate Change (UNFCCC). However, the current transition that the energy sector in Ecuador is undergoing may enable solutions based on demand-side management (DSM). The purpose of this work is to investigate the use of DSM measures that ...

Driven by the energy auctions system, wind power in Brazil is undergoing a phase of expansion within its electric energy mix. Due to wind’s stochastic nature and variability, the wind measurement campaign duration of a wind farm project is required to last for a minimum of 36 months in order for it to partake in energy auctions. In this respect, the influence of such duration on a measure-correlate-predict (MCP) based wind resource assessment was studied to assess the accuracy of generation forecasts. ...

This article develops an ecological economic interpretation of the Jevons effect. Moreover, it is argued that under the neoclassical paradigm there are no elements with which to foresee the long-term existence of this phenomenon. The objective of these arguments is to demonstrate that the Jevons effect can be used to compare the ability of neoclassical and ecological economics describing the social appropriation of nature. This is elaborated in two steps. First, we show the importance of the thesis ...

Slums are populated poor areas inside urban centers, mostly deprived of good-quality public services and exposed to inappropriate waste disposal and energy poverty. Using the organic fraction waste from these communities to generate high value-added products, including electricity, heat, and fertilizer, provides a circular bioeconomy with mitigation of greenhouse gas emissions, reducing environmental pollution and diseases. The present study aimed to demonstrate the feasibility of producing bioelectricity ...

This work presents an extensive study on methodologies to calibrate electric energy consumption in buildings. A comparison between several calibration methodologies shows different approaches addressing the same issue, suggesting a lack of a unique methodology that is reproducible for every building. Additionally, no methodology fits the Brazilian public context, such as the predominance of Unitary Air Conditioning Systems (UACS) and buildings which have operated for more than 30 years. A new calibration ...

The most robust methods to determine the capacity contribution from intermittent sources combine load curve, variable generation profile, and dispatchable generators’ data to calculate any new inserted variable source’s capacity value in the power system. However, these methods invariably adopt the premise that the system’s dispatchable generators’ capacity is constant. That is an unacceptable limitation when the energy mix has a large share of hydroelectric sources. Hydroelectric plants are dispatchable ...
