Momentum has been building for an EU-wide approach to energy policy in which energy end-use efficiency is regarded as one of the main planks. Member States are already obliged to plan for the achievement of energy savings targets in respect of the period 2008-2016 and they now face additional...

This paper assesses the impacts of a targeted policy designed to influence car purchasing trends towards lower CO2 emitting vehicles. Vehicle registration tax and annual motor tax rates in Ireland changed in July 2008 from being based on engine size to emissions performance of cars. This paper...

Several index decomposition methods are commonly employed to provide a top-down view of energy consumption trends in manufacturing industry. These approaches typically use value added data for an industrial sector to decompose energy trends into structural, intensity and activity effects....

Index decomposition analysis based on economic output is frequently employed to provide an indication of energy intensity trends in industry. Additionally, composite energy efficiency indicators, calculated using physical output, are used to give a more accurate view of energy efficiency...

One of the most notable outcomes of Ireland's recent spectacular rise in income was an apparent 140% increase in domestic passenger transport fuel use from 1990 to 2008, at the same time as the car stock has more than doubled in magnitude. However, there have been very few comparisons and...

Targeted measures influencing vehicle technology are increasingly a tool of energy policy makers within the EU as a means of meeting energy efficiency, renewable energy, climate change and energy security goals. This paper develops the modelling capacity for analysing and evaluating such...

In this paper we use a technological model of Ireland's future car stock to simulate the impact of a range of policy measures on the baseline trend in energy demand in the period to 2030. The policies and measures modelled comprise meeting deployment targets for electric vehicles and compressed...

To-date, decomposition analysis has been widely used at the macro-economic level and for in-depth analyses of the industry and transport sectors; however, its application in the residential sector has been rare. This paper uses the Log-Mean Divisia Index I (LMDI-I) methodology to decompose gas...

Freight transport is both significant and fast growing in terms of energy use but there are few papers that focus on modelling future freight transport energy use. This paper addresses this knowledge gap, focussing on Ireland, which is an interesting case study because it has witnessed a...
