Since 1995 Brazil has been applying its labeling program to increase the efficiency of application of many household appliances and equipment. From 2003 on inductions motors have also been receiving the PROCEL2 prize, which helped push motors efficiency over than those limits established by the labeling program. Therefore, this work presents the development of a […]

Potential of Sugarcane in Modern Energy Development in Southern Africa.

Posted Leave a commentPosted in Artigo, Excen, Luiz Horta Nogueira

Most of the population of Southern African lacks access to electricity and modern energy for cooking (FAO, 2012c; IEA, 2014a). Their heavy dependence on the traditional biomass for cooking direct affect the living conditions in this region. For example, charcoal and firewood supply more than 95% of the cooking energy consumption in Mozambique and Malawi. […]

Biodiesel program in Brazil: learning curve over ten years (2005-2015).

Posted Leave a commentPosted in Artigo, Excen, Luiz Horta Nogueira

The biodiesel blending mandate was launched at 2005 in Brazil, by a governmental program based mainly on sustainability concerns, especially toward social and environmental aspects. Since 2007, B7, i.e., 7% biodiesel in diesel, in volume terms, has been mandatory, and B10 is the next target. In this context, this paper aims to evaluate the biodiesel […]

Sugarcane: a way out of energy poverty.

Posted Leave a commentPosted in Artigo, Excen, Luiz Horta Nogueira

Universal access to modern energy is required if the world is to reduce poverty and enable sustainable development. Energy poverty is the lack of access to safe and efficient energy carriers. It affects more than 1.3 billion people without electricity and 2.7 billion without appropriate cooking facilities and fuels, particularly in sub-Saharan Africa (SSA). Under […]

Perspectives for Sustainable Aviation Biofuels in Brazil.

Posted Leave a commentPosted in Artigo, Excen, Luiz Horta Nogueira

The aviation industry has set ambitious goals to reduce carbon emissions in coming decades. The strategy involves the use of sustainable biofuels, aiming to achieve benefits from environmental, social, and economic perspectives. In this context, Brazilian conditions are favorable, with a mature agroindustry that regularly produces automotive biofuel largely adopted by Brazilian road vehicles, while […]

Avaliação da eficiência energética na iluminação pública: proposta de modelagem considerando a variabilidade climática.

Posted Leave a commentPosted in Artigo, Excen, Luiz Horta Nogueira

O objetivo deste artigo é propor uma metodologia para avaliar os impactos da variabilidade climática no consumo eficiente de energia elétrica na iluminação pública no Brasil. Foi aplicado o Método por Demanda Climática (MDC) e calculado a economia de energia das ações do Programa Nacional de Iluminação Pública Eficiente (ReLuz) em 2005, considerando a climatologia […]

Evaluation of the energy impacts of the Energy Efficiency Law in Brazil.

Posted Leave a commentPosted in Artigo, Excen, Luiz Horta Nogueira

Minimum energy performance standards (MEPSs) have been adopted in several countries to promote energy efficiency. This study evaluates the impacts of Law 10.295/2001 which regulates the efficiency of equipment in Brazil. This impact assessment was based on estimates of the amount of equipment in operation and the effect of MEPS on a representative model of […]

Life cycle assessment (LCA) for biofuels in Brazilian conditions: A meta-analysis.

Posted Leave a commentPosted in Artigo, Excen, Luiz Horta Nogueira

The key objective of this study is to evaluate and compare the main environmental life cycle impacts and energy balance of ethanol from sugarcane and biodiesel from soybean and palm oil, in the Brazilian conditions. The methodological tool used was the Life Cycle Assessment (LCA), in Well-To-Tank (WTT) perspective. A process based on cradle-to-gate attribution […]

The impact on electricity demand and emissions due to the introduction of electric cars in the São Paulo Power System.

Posted Leave a commentPosted in Edson da Costa Bortoni, Jamil Haddad, Luiz Horta Nogueira, Marcos Vinícius Xavier Dias, Roberto Akira Yamachita

Over the past years, the pursuit of using less polluting energy sources throughout society has been on the increase. In general, the transportation sector is responsible for most of the emissions of greenhouse gases. Therefore, in this article a methodological approach is applied in such a way that it is possible to quantify the impact […]
