The purpose of this presentation is to provide a brief introduction to measurement uncertainty analysis, outline how it is done, and illustrate uncertainty analysis with examples drawn from the PV field, with particular emphasis toward its use in PV performance measurements. The uncertainty...

Petrol consumption has become one of the most important sustainability issues forAustralia. The central contention in this article is whether Australia's current FringeBenefits Tax (FBT) regime is promoting unnecessary mileage (and use of petrol) insalary packaged vehicles to obtain tax...

This paper explores the potential of utility-scale PV power, and, specifically, the opportunity that may arise for concentrating photovoltaics (CPV). In the 1990s, sales of PV modules were dominated by small-size applications such as PV-powered water pumping, emergency telephones, and...

A expansão dos níveis de produção perseguidos atualmente com vistas à elevação dos níveis de emprego e renda gerados pela economia e a manutenção dos padrões de consumo demandados pela sociedade fazem com que haja uma crescente pressão sobre os recursos naturais. A análise dos...

Life cycle analysis (LCA) is the standard approach used to evaluate the greenhouse gas (GHG) benefits of biofuels. However, it is increasingly recognized that LCA results do not account for some impacts including land use changes that have important implications on GHGs. Thus, an alternative...

In the following decades there will be a fundamental structural change in the European power supply system. This structural change is forced by several factors, e.g. the European Union Greenhouse Gas Emission Trading Scheme, the strategic goal for the European Union of a more sustainable...

If geothermal heat pumps (GHPs) are to make a significant mark in the market, we believe that it will be through energy service pricing contracts offered by retailcos. The benefits of GHPs are ideally suited to energy service pricing (ESP) contractual arrangements; however, few retailcos are...

The Depleted Uranium Hexafluoride (DUF{sub 6}) Management System (DMS) is being developed as a decision tool to provide cost and risk data for evaluation of short-and long-term management strategies for depleted uranium. It can be used to assist decision makers on a programmatic or site-specific...

Analyses of alternative futures often present results for a limited set of scenarios, with little if any sensitivity analysis to identify the factors affecting the scenario results. This approach creates an artificial impression of certainty associated with the scenarios considered, and inhibits...

This report describes methods for prioritizing the risk importances of maintenances using a Probabilistic Risk Assessment (PRA). Approaches then are described for quantifying their reliability and risk effects. Two different PRA importance measures, minimal cutset importances and risk reduction...
