Energy systems can be vulnerable to climate change. This paper summarizes the contribution of their authors to a few strategic studies, research workshops, development forum and international conferences related to Climate and Energy. It presents a review of the impacts that climate change may...

This study evaluates the possibility of installing an offshore gas-to-liquids (GTL) plant in Brazil to reduce Natural Gas (NG) flaring, curb carbon dioxide equivalent (CO2e) emissions and produce premium diesel. CO2e emissions abatement costs were estimated by comparing two alternatives. The...

Several studies have proposed different tools for analyzing the integration of variable renewable energy into power grids. This study applies an optimization tool to model the expansion of the electric power system in northeastern Brazil, enabling the most efficient dispatch of the variable...

The more stringent environmental quality specifications for oil products worldwide are tending to step up energy use and, consequently, CO2 emissions at refineries. In Brazil, for example, the stipulated reduction in the sulfur content of diesel and gasoline between 2002 and 2009 should increase...

Several studies hypothetically assume that investors are increasingly using socio-environmental criteria to configure their portfolios. If this is true, oil companies should strive to achieve an environmentally correct image, especially by adhering to sustainability indexes in the capital...

In this viewpoint, we discuss the importance of consorting alternative energy sources with oil, and not of opposing them. That is why we introduce the concept of alternative energy systems, which we feel is broader-ranging and more effective than alternative energy sources, as this deals with...

Some Latin American policy-makers and analysts state that it would be better to hold oil reserves in place than to produce and cash it now, given the recent oil prices spikes and the fear related to future oil supply disruptions. This article evaluates the strategy of delaying the start-up of...

This paper assessed the economic impact of alternative depreciation methods on the development of combined heat-and-power (CHP) systems in the Brazilian industrial sector. Alternative depreciation methods were proposed and the case study of a Brazilian chemical plant showed that the most...

Integrated assessment models have been extensively used to examine long term energy and greenhouse emissions trajectories, but these models have rarely been examined with respect to their ability to capture historical dynamics. We evaluate the USA buildings component of the Global Change...

Buildings are an important contributor to China's energy consumption and attendant CO2 emissions. Measures to address energy consumption and associated emissions from the buildings sector will be an important part of strategy to reduce the country's CO2 emissions. This study presents a detailed,...
