Understand the three different scales for measuring primary energy and avoid errors

Lightfoot, H. Douglas - In: Energy 32 (2007) 8, pp. 1478-1483

Three quite different scales for measuring the amount of primary energy the world uses annually are currently in use. The Engineering Information Administration, the International Energy Agency and the Working Group III (WG III) of the Intergovernmental Panel on Climate Change (IPCC), each has...

The Divisia real energy intensity indices: Evolution and attribution of percent changes in 20 European countries from 1995 to 2010

Fernández González, P.; Landajo, M.; Presno, M.J. - In: Energy 58 (2013) C, pp. 340-349

This paper analyzes the evolution of real energy efficiency in the European Union and the attribution across countries of its percent change. Relying on a multiplicative energy intensity approach that is implemented through the Sato-Vartia Logarithmic Mean Divisia Index method, we decompose the...

Valuing the preferences for micro-generation of renewables by househoulds

van Putten, Marloes; Lijesen, Mark; Özel, Tanju; Vink, … - In: Energy 71 (2014) C, pp. 596-604

We study the valuation of preferences for small scale initiatives in renewable electricity generation. We analyse the results of a stated choice experiment among 507 respondents in The Netherlands and provide valuations of characteristics of small scale initiatives. Respondents prefer installing...

Investigating the energy-environmental Kuznets curve

Luzzati, T.; Orsini, M. - In: Energy 34 (2009) 3, pp. 291-300

This paper investigates the relationship between absolute energy consumption and gross domestic product (GDP) per capita for 113 countries over the period 1971–2004. Energy has been scarcely explored in the Environmental Kuznets curve (EKC) debate and is taken as the indicator of overall...

The impact of energy consumption and CO2 emission on the economic growth and financial development in the Sub Saharan African countries

Al-mulali, Usama; Sab, Binti Che; Normee, Che - In: Energy 39 (2012) 1, pp. 180-186

This study investigated the impact of energy consumption and CO2 emission on GDP (gross domestic product) growth and the financial development in thirty Sub Saharan African Countries. The panel model was used in this study from the period 1980 to 2008. The results showed that energy consumption...

Attribution of changes in the generalized Fisher index with application to embodied emission studies

Su, Bin; Ang, B.W. - In: Energy 69 (2014) C, pp. 778-786

The Fisher index and its extensions have been used in multiplicative decomposition analysis applied to energy and emissions. In this study, we extend the concept of “additive decomposition of the Fisher index” in the national accounts and propose an attribution analysis of the generalized...
