Energy supply in Brazil relies heavily on renewable energy source. The production of energy from renewable sources, however, greatly depends on climatic conditions, which may be impacted in the future due to global climate change (GCC). This paper analyzes the vulnerabilities of renewable energy...

This study assesses the impacts of promoting, through auctions, centralized solar power generation (concentrated solar power – CSP, and photovoltaic solar panels – PV) on the Brazilian power system. Four types of CSP plants with parabolic troughs were simulated at two sites, Bom Jesus da...

Although the life cycle environmental impacts of biofuels have been recently reported, studies that focus on specific regions and use real fleet data for the use phase are still lacking. In Pennsylvania, the Penn Security Fuels Initiative required 2% biodiesel (B2), effective on January 1, 2010,...

With energy security, economic stabilization, and environmental sustainability being at the forefront of US policy making, the development of biodiesel production and use within the United States has been growing at an astonishing rate. According to the latest DOE energy report, biodiesel...

A large share of Brazil's current investments is concentrated in the development of petroleum resources in new frontiers. Perspectives for large offshore pre-salt fields are particularly good. However, challenges are also huge. On one hand, pre-salt resources development will draw vast amounts...

Carbon capture and storage (CCS) is an effective technology for the mitigation of greenhouse gas emissions from large-scale fossil fuel use. Nonetheless, it is not yet commercially viable on a large scale, and its inclusion into countries' energy planning agendas depends on realistic assessments...

This study shows how the assessment of emissions reductions from CO2 capture is critically dependent on the choice of multi-gas equivalency metric and climate impact time horizon. This has implications for time-sensitive mitigation policies, in particular when considering relative impact of...

The deepwater horizon accident may have shaken the sustainability ratings and indices credibility, but it also reinforced their importance. The objective of this article is to contribute to the improvement of corporate sustainability valuations by investigating if reserves profiles can affect...

This paper estimates the potential for energy-related greenhouse gas emission (GHG) reductions in Brazil, their abatement costs and proposes a number of policies to achieve these reductions. The Brazilian energy system is very peculiar as renewable energy accounts for some 45% of total primary...
