0 INTRODUCTION
Manufacturing is defined as the transformation
of materials and information into goods for the
satisfaction of human needs. Turning raw materials
into consumer products is also a major source
of environmental pollution. Waste coming from
manufacturing activities is an environmental threat
originating in several regions around the world [1].
Therefore, in recent years, mostly in response to
increasing pressure from environmental regulations,
many manufacturing firms have made significant
efforts to use cleaner production methods [2] to [4].
Industrial energy efficiency plays a central role
as the manufacturing industry accounts for about 75%
of the world’s yearly coal consumption, 44% of the
world’s natural gas consumption, and 20% of global
oil consumption. In addition, these manufacturing
firms also use 42% of all the electricity generated
[5]. Although renewable energy technologies, such
as photovoltaic technology, might be a long-term
solution, more efficient energy use can make the
greatest and most economic contribution towards
solving these problems in the short run. Using the
available energy more efficiently is an effective
countermeasure to rising energy needs and insecure
energy supplies [6] and[7]. Bunse et al. [8] argue that
examples in the literature and in real world practice
show that although the manufacturing sector has made
continuous improvements in energy efficiency, the
economically beneficial energy efficiency potential
has not yet been fully exploited [8] to [10].
This paper is based on an empirical study in the
field of energy and material efficiency technologies.
The objective of this paper is firstly to map the
adoption of technologies for the reduction of energy
and resource consumption in production and, second,
to contribute to the identification and understanding of
the characteristics of the manufacturing firms that use
these kinds of innovative technologies.
The paper is organized as follows. The
introduction comprises a background and literature
review of energy efficiency in production. Next,
the research methodology and methods used to
analyse the characteristics of energy and material
saving technologies’ adoption and their adopters are
presented. The results and findings are presented for
the manufacturing firms with the use of descriptive
statistics and simple correlation tests. Finally, we
discuss our results and present some implications.
1 LITERATURE REVIEW
The energy efficiency of manufacturing processes is
becoming increasingly important due to rising energy
costs and climate altering greenhouse gas emissions
[11]. Improving energy efficiency is regarded as one
of the most important options for reducing greenhouse
gas emissions and for reducing the dependency
of countries on energy imports [12]. Measuring
energy efficiency is the basis for controlling energy
consumption in the production processes and for
deciding on improvement measures, as well as
for tracking changes and improvements in energy
efficiency [8]. Studies on the energy consumption of
manufacturing processes have provided fundamental
information for improving energy efficiency and
building a comprehensive foundation aimed at
Analysing Energy and Material Saving Technologies’
Adoption and Adopters

The main objective of this paper is to map the adoption of technologies for energy reduction and resources consumption in production.
The aim is also to contribute to the identification and understanding of the characteristics of the manufacturing firms that use these kinds
of energy and material saving technologies. Our research is based on data from the largest European manufacturing survey to date and it
includes data from Spain and Slovenia. The results show that the use of specific energy saving technologies and material saving technologies
in manufacturing firms is still modest. Dividing manufacturing firms based on technology intensity sectors and based on their relative energy
efficiency we have concluded that firms in high technology industries focus less on energy efficiency than low technology firms. Some other
specific relationships between the use of energy efficient technologies and adopters’ characteristics (e. g. use of environmental management
systems) are presented in this paper.
