years. Another relatively small group of articles (22) was classified as research about
behaviour with reference to the energy context. The main focus areas in this group
of articles are about the role of individuals and their engagement regarding energy
conservation attitudes and knowledge, behaviour changes and consumption habits,
pro-environmental and energy behaviour (Fernández et al. 2016; Kaplowitz et al.
2012; Pothitou et al. 2017). Both bibliometric and behaviour studies had their first
publications after 2010 (Fig. 7b).
A larger number of articles were observed in the category of energy efficiency
research in the building sector. In total 73 articles focused on matters related to
energy performance in buildings, LEED certification, green buildings, framework
assessment of energy efficiency or energy use (Agdas et al. 2015; Asdrubali et al.
2013; Chokor et al. 2015). Between 2012 and 2016, the number of articles of this
kind increased noticeably.
Renewable energy and energy efficiency are the research areas with the largest
number of articles in the whole analysis: 151 and 155, respectively. They stand out
in Fig. 7b, with their significant increase in number of published articles over the
past ten years. When it comes to renewable energy, the articles present many different approaches, including wind, solar, ocean and thermal energy, biomass and
biofuels production and hydrogen energy systems, amongst others. Most of these are
experimental studies, seeking to improve the use of renewable energy resources or
their performance evaluation (Cotana et al. 2016; Lee et al. 2016; Salem et al. 2017).
