A multi-period mixed-integer linear programming model has been developed to help explore future pathways for electricity supply where costs and carbon reduction are a priority. The model follows a life cycle approach and can optimise on costs and on a number of environmental objectives. To...

Since the end of 1993, when a new administration took the lead of the city of Palermo, the energy and environmental issues started to rank quite high in the priority list.

The main purpose of this paper was to carry out a systematic analysis of the particularities and trends pertaining to the development of biofuels in Brazil—a country which has demonstrated its leadership in this field during the last 40 years. The Brazilian experiences with biofuels are often...

This article analyzes the thermal energy options available in the country to support the expansion of Brazil's electricity grid capacity. The country's electricity mix consists primarily of renewable sources of energy and this configuration will be maintained throughout the 21st century....

The State of Paraná contributes significantly for the Brazilian production of sugar cane, ethanol, soybeans and pigs. In addition to the current production of ethanol, the State has a huge potential for electricity, biodiesel and biogas production. This paper presents an overview of the current...

There are increasing numbers of annual and periodical energy studies that look into future energy demand and sustainability issues. Among these the World Energy Outlook stands out as the most important futuristic energy study and analysis. The 2011 Outlook is in four parts and gives a full...

An energy-system model incorporating generation, transmission and integrated management of hydroelectric reservoirs in British Columbia (BC) is used to explore approaches to meeting load projections to 2040. The model includes electricity trade between BC, Alberta and the US, the influence of a...

This paper proposes a new approach to deal with the problem of building national energy efficiency (EE) plans, considering multiple objectives instead of only energy savings. The objectives considered are minimizing the influence of energy use on climate change, minimizing the financial risk...

This work seeks to identify the fundamental objectives behind the development of energy efficiency (EE) plans for countries. It also presents a method to quantify the degree of achievement of each objective, through the identification and operationalization of attributes. This was achieved by...

The prevalence of energy resources on American Indian lands, the links between energy management and tribal sovereignty, and recent federal government incentives make tribal energy planning an interesting case study for community energy planning in the US. This paper studies the strategic energy...
