Special Issue Information

Dear Colleagues,

Recently we have observed an impetuous revolution in the field of the generation of electrical energy. Until some years ago, electrical energy was generated in large quantity in large centralized power units (typical power in the order of MWs and much higher) and successively distributed. The developing of several technologies (PV systems, small hydro power unit, small wind turbines, etc.) has allowed, in the last decade, the economical possibility to produce smaller quantity of energy in more distributed power units (typical power in the order of kWs), starting the ongoing revolution in the field of distributed energies. These technologies have opened the field to the general application of otherwise unaffordable technical solutions; however, other fields are still limited by the fact that the generation of energy in the range of watts and subwatts is still difficult and expensive. The typical solution that is adopted in order to supply power in the order of the watts or subwatts is based on the use of batteries, with all the related issues and problems (in terms of safety, reliability, maintenance, etc.) that this solution causes. This approach strongly limits several other fields: a full development of Internet of Things has as enabling technology the possibility to have energy in the same place where the myriads of sensors will be installed; the development of a new battery free generation of reliable, safe, and installable medical devices is based on the use of energy harvesting technologies; and the installation of distributed networks of sensors in large structures requires a simple approach to supply the needed energy,  just to mention a few examples. A key factor in the full development of energy harvesting technology is related to the maximization of the efficiency of the usage of the produced energy to maximize the performance of the overall system. 

Fortunately, nowadays several technologies that are able to extract energy from the surrounding environment are being studied and becoming available. As a result, this Special Issue intends to stimulate a discussion of the available and nearly-available technologies in the field of the energy harvesting systems whose power is lower than few kWs (up to micro watts or less). Papers on both the power units and the typical applications will be considered, and special attention will be given to the studies on energy saving in energy harvesting applications.

The aim of this paper is to investigate households’ willingness to adopt technological and behavioral energy savings measures, in their dwellings and for daily mobility. Based on the evidence that occupants’ behavior has a major impact on energy uses at home and on the road, this paper aims at investigating which determinants influence household preferences for energy-saving measures, both technical as well as behavioral ones, as well as highlighting the key determinants for adopting energy-savings measures, at the household scale. This paper will attempt to shed more light on the factors that may bridge the intention–behavior gap. The analysis is based on an empirical survey carried out in the Netherlands. Main results show that (1) behavioral energy saving measures are more acceptable than technical ones; (2) the adoption of energy savings measures at home is more likely than on the road; (3) there is a relatively small market for technical energy measures, especially through the initial investment and the low return on investment; (4) environmental aspects seem to be more important for relatively expensive technical energy measures; (5) the reason for taking technological energy measures is rather to be found in differences among socio-demographic background than in environmental concerns; and (6) comfort at home and on the road is an important explanatory variable that many respondents used to justify not implementing energy savings measures and should be investigated in further research.
