The bioeconomy aims at decreasing reliance on fossil fuels, preventing or reducing climate change, eliminating insecurity, and efficiently using resources; however, fierce controversy exists on conceivable pathways to accomplish these objectives. The transport sector alone, which encompasses all other industrial sectors, has grown with regard to its energy demand by 50% over the past 30 years. The aim of this paper is to promote a dialogue as to whether an economy based on biomass can be more sustainable than today’s existing economies, considering that the economy needs to expand and be boosted, while creating a cascading and recycling system. This semi-systematic review paper discusses four research questions based on findings from the last 20 years: (i) What are the crucial issues in the ongoing debate on the development of a sustainable bioeconomy concept? (ii) Where are the major conflicting points and focuses? (iii) How does the bioeconomy follow current urbanization and land-abandonment trends? (iv) How will the crisis linked to the COVID-19 pandemic change these previous scenarios? As it is not easy to currently predict which pathway will be the most effective, whether it be the one taken as of now or a specific novel pathway, this article recommends following a strategy that is diverse regarding its approaches to shaping the bioeconomy and further funding of renewable energy sources, along with the involvement of urban planning. In addition, conclusions are validated through a questionnaire completed by 51 experts in the field.

This paper is built on the following research questions: (i) What are the direct/indirect relationships between Sustainable Development Goal 11 (SDG11) and sustainability protocols? (ii) Could the sustainability protocols constitute a solution towards the achievement of SDG11? We underline that, on the one hand, the SDGs are guidelines to support the development of sustainable policies and thus address all elements that may affect them, and on the other hand, sustainability protocols are assessment tools to promote sustainability-conscious design while remaining focused on the built environment. In the Italian regulatory context, the paper highlights how this difference in terms of focus and scale means that they only overlap and mutually reinforce each other with regard to certain aspects, more related to energy and air pollution issues and less to the social aspects of sustainability. Even if there is not always a direct relationship between the evaluation criteria of the protocols and the indicators of SDG11, it is possible to conclude that the sustainability protocols can facilitate the achievement of the SDG11 targets, acting as a key for the implementation of sustainable cities and helping in structuring the process leading to sustainability in a broader framework.

World Concept

Present energy use - largely dependent on fossil fuels - is incompatible with the sustainable world concept. In a sustainable world, energy sources are renewable and used in a way that damage to the environment is minimalized. This study investigates the possibility of a sustainable world using renewable energy sources. It appears that - when strict energy conservation is applied - such a sustainable world seems to be attainable. This requires, however, drastic changes in most parts of society.

Abstract Today, the fossil fuels have dominant share of energy supply in order to respond to the high energy demand in the world. Norway is one of the countries with rich sources of fossil fuels and renewable energy sources. The current work is to investigate on the status of energy demand in Norway. First, energy and electricity consumption in various sectors, including industrial, residential are calculated. Then, energy demand in Norway is forecasted by using available tools. After that, the relationship between energy consumption in Norway with Basic economics parameters such as GDP, population and industry growth rate has determined by using linear regression model. Finally, the regression result shows a low correlation between variables.

Reality is complex, and often does not lend itself to generalization or simplifying explanations. Yet at the same time, explaining reality often requires the shaping of notions and concepts of it through generalization and the reduction of complexity. This tension between complexity and particularity on the one hand and generalization and the search for abstracting explanatory patterns on the other is beautifully illustrated by two recently released publications on precaution and risk regulation in the United States and Europe, namely “The Politics of Precaution” by David Vogel1 and “The Reality of Precaution” edited by Jonathan Wiener, Michael Rogers, James Hammitt, and Peter Sand.Both books together can be seen as the latest significant contribution to the ongoing debate on the role of the precautionary principle in risk regulation in a comparative EU-US perspective. Both contributions are significant in that they consolidate the trend towards an empirically informed analysis of the actual practice of the application of precaution in risk regulation.

Currently, most of the vehicles make use of fossil fuels for operations, resulting in one of the largest sources of carbon dioxide emissions. The need to cut our dependency on these fossil fuels has led to an increased use of renewable energy sources (RESs) for mobility purposes. A technical and economic analysis of a one-stop charging station for battery electric vehicles (BEV) and fuel cell electric vehicles (FCEV) is investigated in this paper. The hybrid optimization model for electric renewables (HOMER) software and the heavy-duty refueling station analysis model (HDRSAM) are used to conduct the case study for a one-stop charging station at Technical University of Denmark (DTU)-Risø campus. Using HOMER, a total of 42 charging station scenarios are analyzed by considering two systems (a grid-connected system and an off-grid connected system). For each system three different charging station designs (design A-hydrogen load; design B-an electrical load, and design C-an integrated system consisting of both hydrogen and electrical load) are set up for analysis. Furthermore, seven potential wind turbines with different capacity are selected from HOMER database for each system. Using HDRSAM, a total 18 scenarios are analyzed with variation in hydrogen delivery option, production volume, hydrogen dispensing option and hydrogen dispensing option. The optimal solution from HOMER for a lifespan of twenty-five years is integrated into design C with the grid-connected system whose cost was $986,065. For HDRSAM, the optimal solution design consists of tube trailer as hydrogen delivery with cascade dispensing option at 350 bar together with high production volume and the cost of the system was $452,148. The results from the two simulation tools are integrated and the overall cost of the one-stop charging station is achieved which was $2,833,465. The analysis demonstrated that the one-stop charging station with a grid connection is able to fulfil the charging demand cost-effectively and environmentally friendly for an integrated energy system with RESs in the investigated locations.

The current energy scenario in the world considering the overconsumption of fossil fuels as well as its disastrous impact on environment calls for the promotion of renewable resources to take part in the growth towards sustainable development. With the penetration of such intermittent renewable energy sources into the existing grid, it not only enhanced the capability of the grid but also posed challenges regarding system stability. A practical solution to these problems by means of a new technological concept called “electric springs” is presented in this paper which enhances the system stability and provides voltage regulation for the same. Reviewing the various analyses, control methodologies as well as applications regarding the electric spring provides the confidence to further analyze its scope in large-scale power distribution system.

The governments world-wide are deliberating to promote renewable energy sources such as wind to mitigate increasing demand of energy and to overcome effects of pollution due to to use of fossil fuels. Integration of wind turbine generators (WTG) with the diesel plants is pursued widely to reduce dependence on fossil-fuels and to reduce carbon emissions. Literature indicates that commercial/residential buildings in the Kingdom of Saudi Arabia (K.S.A) consume an estimated 10 - 40% of the total electric energy generated. The aim of this study is to analyze wind-speed data of Dhahran (East-Coast, K.S.A.) to assess the economic feasibility of utilizing hybrid wind-diesel power systems to meet the load requirements of a typical commercial building (with annual electrical energy demand of 620,000 kWh). The monthly average wind speeds range from 3.3 to 5.6 m/s. The hybrid systems simulated consist of different combinations of 100 kW commercial WTG supplemented with diesel generators. NREL?s (HOMER Energy?s) HOMER software has been employed to perform the techno-economic analysis. The simulation results indicate that for a hybrid system comprising of 100 kW wind capacity together with 175 kW diesel system, the wind penetration (at 37 m hub-height, with 0% annual capacity shortage) is 25%. The cost of generating energy (COE, $/kWh) from this hybrid wind-diesel system has been found to be 0.121 $/kWh (assuming diesel fuel price of 0.1$/liter). The study exhibits that for a given hybrid configuration, the number of operational hours of diesel gensets decreases with increase in wind farm capacity. Emphasis has also been placed on wind penetration, un-met load, energy production and COE, excess electricity generation, percentage fuel savings and reduction in carbon emissions (relative to diesel-only situation) of different hybrid systems, cost break-down of wind-diesel systems, COE of different hybrid systems, etc.

Abstract The need for wastewater treatment is progressively rising as the release of copious amounts of industrial wastewater is increasing. Likewise, there is an urgent requirement for renewable energy sources because of the growing energy demand and depletion of fossil fuels. The use of microalgae to convert toxic phenolic wastewater to lipid-enriched biofuel has recently been proposed. Here, we report a new strategy for coupling N-doped TiO2-coated photocatalytic optical fibers and a microalgal biofilm to degrade 4-chlorophenol (4-CP) and produce biomass. In the combined photocatalysis and biodegradation system, the photocatalytic products were directly biodegraded by the heterotroph-enriched (Salinarimonas and Pseudomonas) biofilm, promoting biomass production; O2 produced by the phototrophs (Scenedesmus obliquus) promoted the generation of hydroxyl free radicals using N-doped TiO2. Thus, the combined photocatalysis and biodegradation system rapidly and sustainably degraded 4-CP while maintaining the growth of the microalgal biomass. The 4-CP removal, dechlorination, and biofilm growth rates reached ~78 µM/h, ~41 µM/h, and 1.8 g/h/m2, respectively. Overall, we present a useful synergy between an optical catalyst and a bioreactor that has implications for both wastewater remediation and sustainable microalgal biomass production.

Industrial Revolutions

Our life, by its biological nature, is in an indestructible dependence on energy. At the same time, energy is an important criterion on which we report the progress of humanity. Historically, progress divides our world into distinct stages, called Industrial Revolutions. Each stage has encompassed more fuels, new technologies, inventions, humans behavioural changes and much more worrying environmental issues. Energy techniques, new extractions and transportation improved in nineteenth and during twenty-century energy consumption, especially electricity, rise significantly with, on the one hand, a continuous influx of fossil fuels and, on the other hand, continuous increase of the quantities of toxic waste, visible or not, from the other industrial branches and human activities, consequences of the energetical progress. The purpose of this paper is to point out some aspects regarding ecological footprints of electrical industry and energy industries during their development and to establish connections between the distinct role of energy in each period of industrialization and its impact on the environment, education, science, arts and cultural dimensions of life.

Administrative Elites

The paper is devoted to presentation of the one aspect of the research project dedicated to study of political administrative elite in contemporary Russia. It is based on the network analysis methodology that is not widely used by Russian scholars of elites. The authors establish their approach on the mapping of the social networks within elite groups. Although the explanatory power of the network approach is still comparatively weak it is applied as exploratory method for structuring of empirical data, find the trends and set the research questions and hypotheses. The study of networks based on the birthplace is presented in the paper. The key research question is the following: are there cohesive subgroups based on birthplace compatriotship in federal executive branch of power? Federal ministers, deputy ministers and heads of departments are included into sample. The authors find that regional compatriotship is not the important factor of the recruitment of the federal political administrative elite. However, in some cases the cohesive groups based on compatriotship ties appear within one ministry. For example, when the authors reduce the sample to those who were born after 1970, several cohesive subgroups of regional compatriots are found.
