Quartiles

The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Country	United Kingdom	22 H Index
Subject Area and Category	Energy Energy Engineering and Power Technology Energy (miscellaneous) Renewable Energy, Sustainability and the Environment Environmental Science Environmental Engineering
Publisher	Multi-Science Publishing Co Ltd.
Publication type	Journals
ISSN	0958305X
Coverage	1981, 1995-ongoing
Scope	Energy use and supply is of fundamental importance to society and, with the possible exception of agriculture and forestry, has made the greatest impact on the environment of any human activity - a result of the large scale and pervasive nature of energy related activities. Although energy and environment concerns were originally local in character - for example, problems associated with extraction, transport or noxious emissions - they have now widened to cover regional and global issues such as acid rain and the greenhouse effect. Such problems have now become major political issues and the subject of international debate and regulation. It is for this reason that there is a need for a journal dedicated to energy and environment issues. (source)
