In this chapter, Gerstlberger, da Mota Pedrosa and Atlason investigate how internal environmental goals affect the product innovation activities of manufacturing firms. Based on 150 surveys and additional qualitative interviews, the chapter highlights that focussing on strategic environmental goals also enhances the general product innovation activities of manufacturing firms. Managers responsible for areas such as corporate strategy, R&D, production and marketing can use this insight to identify and implement strategic environmental goals for their firms. These goals will, for example, lead to significant reductions in energy and/or material consumption in specific fields related to new product development, including production, product use, product refurbishment, maintenance of products and production facilities.

The Kano model for user satisfaction is a popular survey-based method used by product designers to prioritize the inclusion and implementation of product features based on users' requirements. Despite its overall simplicity, a current drawback of the Kano approach is that the data analysis and processing of users' responses is laborsome and rather prone to human error. To address this drawback, this paper provides and presents a complete code to conduct a rapid yet comprehensive computation and visualization of Kano data in R. A detailed walkthrough of the code is provided, together with a sample dataset to demonstrate its functionality. The code is encapsulated on a simple function that can substantially decrease the time for evaluating Kano results, speeding up its application in the context of product development.

In this paper, the societal Energy Return on Investment (EROIsocEROIsoc) is estimated for Iceland between 1960 and the present. The results indicate that the overall EROIsocEROIsoc was around 27:1 in the early 1960s, and was volatile for a period of time before stabilizing at around 45:1 in 1974 after establishing a strong mix of renewable energy. These findings further show that Icelanders have generally had access to energy sources with higher EROI than if they had relied on fossil fuels, except for the period between 1963 and 1967. If they had relied on fossil fuels alone, Icelanders would now have access to combined resources with an EROI of around 16:1, likely too low for prosperity, and an even lower EROI for long periods of time. Regarding policies, this paper shows that relying on an energy grid mix with an EROI higher than 20-30:1, especially for island nations, has the potential to raise the standard of living greatly. For policymakers in island nations, attention should be given to this relationship between high-EROI energy sources with low price volatility and the standard of living.

The Icelandic society is conveniently located where the Eurasian and North-American tectonic plates meet. This allows for relatively easy and cheap access to geothermal energy. Icelanders have benefited from this since settlement, first through direct use of the warm water but later on by co-producing electricity. The nation also benefits from large glacial rivers, offering potential for energy harvesting. This chapter explores the various benefits from utilising renewable energy, using Iceland as a case study. This is demonstrated by exploring the energy return on investment (EROI) for the Nesjavellir geothermal and Fljotsdalsstod hydro power plant and the CO2 mitigation provided by the resources as the Icelandic society no longer needs to rely on fossil fuels for electricity and heating. This chapter demonstrates systematically how societies may benefit ecologically but also energetically from access to renewable energy sources.

The Kano model of customer satisfaction provides product developers valuable information about if, and then how much a given functional requirement (FR) will impact customer satisfaction if implemented within a product, system or a service. A limitation of the Kano model is that it does not allow developers to visualize which combined sets of FRs would provide the highest satisfaction between different customer segments. In this paper, a stepwise method to address this shortcoming is presented. First, a traditional Kano analysis is conducted for the different segments of interest. Second, for each FR, relationship functions are integrated between x = 0 and x = 1. Third, integrals are inserted into a matrix crossing segments and FRs, where FRs with the highest sum across the chosen segments are identified. Finally, the functions of the chosen segments with the smallest interval, define the FRs appealing to the biggest target group. The proposed extension should assist product developers within to more effectively evaluate which FRs should be implemented when considering more than one combined customer segment. It shows which segments provide the highest possibility for high satisfaction of combined FRs. We demonstrate the approach in a case study involving customers’ preference for outdoor sports equipment.

Heat pumps use the temperature difference between inside and outside areas to modify a refrigerant, either for heating or cooling. Doing so can lower the need for external heating energy for a household to some extent. The eventual impact depends on various factors, such as the external source for heating or cooling and the temperature difference. The use of heat pumps, and eventual benefits has not been studied in the context of subarctic areas, such as in Iceland. In Iceland, only remote areas do not have access to district heating from geothermal energy where households may, therefore, benefit from using heat pumps. It is the intent of this study to explore the observed benefits of using heat pumps in Iceland, both financially and energetically. This study further elaborates on incentives provided by the Icelandic government. Real data were gathered from the Icelandic energy authority for the analysis. It was found for the study database of 128 households that the annual electricity use was reduced from 37.8 to 26.7 kWh (an average 29.3% reduction) after installation of heat pumps. Large pumps (9.0–14.4 kW) and small pumps (5.0–9.0 kW) saved an average of 31.4 and 26.0% (95% confidence intervals), respectively. On average, households used approximately 26 MWh after installing a heat pump. When installing a small pump (5–9 kW), the mean annual saving (and 95% confidence intervals) was 10.6 (\({\pm }\)2.7) MWh (approximately 26%). However, when installing a larger pump, mean annual savings were 11.3 (\({\pm }\)1.6) MWh (Approximately 31%).

Energy use in food production is linked to environmental impact, as most agricultural practices are reliant on fossil fuels. It is therefore of importance to locate food production methods that are less energy intensive than current methods and are also less polluting. Energy return on investment (EROI) is the ratio between the energy used to construct and maintain a given energy production system, against the energy that is provided by the system. Aquaponic systems have environmental benefits over conventional aquaculture systems as the waste is used within the system as fertilizer for plants. In this paper, we analyse the operational performance of three aquaponic systems. Two systems were located in Iceland, and one in northern Spain. We also analyse the energy output with respect to edible protein contents. After 10 years of partially simulated operation, the EROI of the Hondarribia, Sudarvogur and Akur systems was 0.055:1, 0.016:1 and 0.106:1, respectively. Our results indicate that aquaponic operations benefit from operating within a greenhouse and that direct electricity consumption is the largest energy input in the aquaponics systems. The aquaponics systems studied returned one half to one tenth the EROI as compared to conventional fisheries or aquaculture.

The challenges of sustainability are becoming more apparent and changes need to take place in how we organise collectively. This book stems from and builds on a collaboration and collective learning between the military and the civilian world in order to facilitate discussion of the current state of triple net zero and long-term and sustainable energy strategies. It is widely recognized that implementation of policies to benefit environmental sustainability, energy security, and preparedness at both military installations and small cities are imperative, since energy is intricately linked to the entire set of net zero goals and vision. Here the focus is especially on learning from best practices across these two domains.

As renewable energy sectors evolve and grow within a country, the need for expertise to maintain its infrastructure grows. Such expertise is often provided by foreign industries. It is in the global interest to facilitate expertise to grow domestically, eventually leading to widespread clusters of industries around a renewable energy sector and a global growth of expertise. This ultimately fast tracks the development in the renewable energy sector since more players become active in developing solutions. In this article the factors influencing domestic development are identified from previous studies conducted within the Icelandic geothermal sector. The cause and effect relationships between the identified factors are then mapped. A system dynamics causal loop diagram based on Icelandic case studies is presented to visualise how the formation of industrial clusters in the renewable energy sector can be initiated. This visualisation, based on the Icelandic geothermal sector, can be of use for other industries in the renewable energy sector who are attempting to conduct their maintenance procedures domestically and increase the rate of innovation within a country.

In a global context, the outlook for the Nordic region is relatively favourable, given its relatively stronger resiliency to climate change impacts in comparison to many other geo-political regions of the world. Overall, the projected climatic changes include increases in mean temperatures and in precipitation, although regional variations can be significant. The countries’ robust institutions and economies give them a strong capacity to adapt to these changes. Still, the need for adaptation to the changing climate has been and still is substantial, and in most of the region, there has been progress on the issue. This paper explores the potential for Nordic cooperation on adaptation; specifically, for the development of a regional adaptation strategy. In particular, it addresses two questions (1) What is the current state of adaptation in the Nordic countries? and (2) What are the potential benefits and weaknesses of a Nordic strategy for adaptation? In order to answer these two questions, this paper examines reviews the current national adaptation policies of each Nordic country and discusses the challenges facing a Nordic strategy and finally assesses the potential for common Nordic adaptation policy and further cooperation.

One of the most frequent problems in geothermal power plants is scaling. If scaling is allowed to build in the wellhead it can hinder the flow from the well. In this study we investigate how exactly that problem was solved at HS Energy in Iceland. We look at the problem, describe it and how it has been successfully solved. The solution, a valve called the Elli valve, which can be regarded a derivative of the Giffard’s injector, is then described. This valve has been shown to allow for a better flow control, less problems with regards to scaling removal and has economical advantages over other control valves. This solution should allow geothermal power plants dealing with scaling problems to use the presented solution to solve it effectively, in a cost efficient manner.

Iceland relies greatly on geothermal energy, for electricity, district heating and industrial activities. It is therefore of great importance that the maintenance on site is carried out quite successfully to minimize down time. Reykjavik Energy is the largest energy company in Iceland utilizing geothermal energy. The company operates two cogenerating geothermal power plants, Hellisheidi (303 MWe and 133 MWt) and Nesjavellir (120 MWe and 300 MWt). In this study we investigate the development of the wellhead maintenance at the Hellisheidi geothermal power plant. We look at the maintenance recommendations provided to on-site employees and how maintenance procedures have developed since the power plant began its operations. We investigate real data retrospectively and use it to calculate expected waiting times between repairs. The result is a maintenance model based on the observed and statistically analyzed data provided by the power company on the maintenance procedures. Such model should prove of great significance to other geothermal power plants in the early stages of planning the wellhead maintenance.
