Evidence shows that global climate change is increasing over time, and requires the adoption of a variety of coping methods. As an alternative for conventional electricity systems, renewable energies are considered to be an important policy tool for reducing greenhouse gas emissions, and therefore, they play an important role in climate change mitigation strategies. Renewable energies, however, may also play a crucial role in climate change adaptation strategies because they can reduce the vulnerability of energy systems to extreme events. The paper examines whether policy-makers in Israel tend to focus on mitigation strategies or on adaptation strategies in renewable energy policy discourse. The results indicate that despite Israel’s minor impact on global greenhouse gas emissions, policy-makers focus more on promoting renewable energies as a climate change mitigation strategy rather than an adaptation strategy. These findings shed light on the important role of international influence—which tends to emphasize mitigation over adaptation—in motivating the domestic policy discourse on renewable energy as a coping method with climate change.

Economic crisis has raised the topic of whether governments should control the economy in order to promote prosperity and create jobs. This idea has specially sprung in relation to the promotion of entire productive sectors which are considered strategic or high-value by planners, one of which is renewable energies. This article analyzes the Spanish experience on subsidizing wind, mini-hydroelectric and photovoltaic energies in order to foster growth and create so-called «green jobs». Results suggest that more jobs are destroyed than those that initially were intended to be created. Key words: Renewable energies, subsidies, job destruction, economic planning, spending stimulus. JEL Classification: E24; E32; H25; H44; O13; Q42; Q43; Q48. Resumen: La crisis económica ha planteado la cuestión de si los gobiernos deberían controlar la economía para promover la prosperidad y crear empleo. Esta idea ha surgido especialmente en relación a la promoción de sectores productivos enteros que se consideran estratégicos o de alto valor por los planificadores, como el sector de las energías renovables. Este artículo analiza la experiencia española en relación con la subvención de las energías eólica, hidroeléctrica y fotovoltaica para impulsar el crecimiento y crear los llamados «empleos verdes». Los resultados sugieren que se destruyen más empleos de los que inicialmente se pretendía crear. Palabras clave: Energías renovables, subvenciones, destrucción de empleos, planificación económica, estímulos de gasto. Clasificación JEL: E24; E32; H25; H44; O13; Q42; Q43; Q48.

Technology parks are considered innovative environments for the development of new technologies, in a dynamic that can be explained by the micro level of multilevel analysis of the theory of sociotechnical transition, by contributing to explain the actors responsible for the process of development and dissemination of technology. The cases analyzed were composed of companies and eco-innovative projects in the renewable energy area of the Itaipu Technological Park. The methodology was based on a study of multiple cases of qualitative nature, supported by content analysis and triangulation of information. The main results showed that the ITP, with the support of its maintainer Itaipu Binacional, created an environment conducive to the development of eco-innovative companies in renewable energies, stimulating the exchange of knowledge between companies and favoring partnerships with national and international companies for technological development.

Hybrid Renewable Energy

This paper presents the modeling and simulation of a hybrid renewable-energy system. The sizing, availability, and contribution of solar photovoltaic, wind energy and hydro energy can be simulated to determine the viability, stability, and cost effectiveness of such systems. The model allows the user to enter site specific data (hourly, daily, monthly, and annually) such as solar radiation, wind speed and precipitation. Users can select the type and size of wind turbine, hydroelectric turbine, photovoltaic panel and the electrical load placed on the hybrid renewable system. The simulation will determine the total power that can be produced on an hourly, daily, monthly and annual basis, the optimum combination of renewable energies, and usage/storage of each type of renewable energies, given the specified system and the collected data. With the help of HyRES, the model, one can determine which hybrid renewable energy system would best suit a specific site, and also help to determine which type of wind turbine, hydroelectric turbine, or photovoltaic panels would best complement each other for that site.

The Relationship

This article provides a critical review of the literature on the relationship between renewable energies and sustainability considering the three dimensions of sustainability: economic, social, and environmental. First, a bibliometric tool is used and then a more in-depth analysis of selected literature is performed, focusing on the type of renewable energy analyzed and the level of development of countries, the dimension of sustainability focused on and the country’s development level, and the type of renewable energies focused on and the dimension of sustainability analyzed. It represents a milestone in the topic giving insights on the state of the art of the research on this research area, enhancing empirical evidence on the kind of relationships and developing a discussion on how closely aligned the political and institutional discourses are with the research concerns. We conclude that, while studies on lower-income countries focus on lower-rung energies, studies on higher-income countries focus on the study of more diversified sources. Moreover, wind–solar energy is the most reported in the articles concerned with environmental sustainability. Our main recommendation is to further investigate the implementation of modern renewable energies in developing countries, to help those countries to climb the energy ladder toward cleaner energy supply.

Positive Results

Renewable energies have great potential to improve agricultural activities and rural development. Positive results are already being achieved with these relatively benign energies in many countries. In Nigeria, there is need to improve agricultural production for the increasing population and to conserve the fossil fuel reserves. Although renewable energy sources such as solar radiation and biomass are abundant, harnessing them for agricultural and rural development needs is very slow. This article extols the virtues of these energy sources, analyses the progress made so far in renewable energy technologies in Nigeria, identifies the major obstacles and suggests some solutions to overcome them.

Technological Challenge

Batteries are a major technological challenge in this new century as they are a key method to make more efficient use of energy. Although today’s Li-ion technology has conquered the portable electronic markets and is still improving, it falls short of meeting the demands dictated by the powering of both hybrid electric vehicles and electric vehicles or by the storage of renewable energies (wind, solar). There is room for optimism as long as we pursue paradigm shifts while keeping in mind the concept of materials sustainability. Some of these concepts, relying on new ways to prepare electrode materials via eco-efficient processes, on the use of organic rather than inorganic materials or new chemistries will be discussed. Achieving these concepts will require the inputs of multiple disciplines.

This research examines the relationship between renewable energy consumption and electricity prices in six South American countries (Argentina, Bolivia, Colombia, Chile, Ecuador and Peru). The methodology used is a panel econometric model with annual data for the period 1990–2015. The results show that the consumption of renewable energies influences the price of electricity paid by households, although its influence is very moderate. On the other hand, it was observed that the consumption of renewable energies has no relationship with the energy prices of the industrial sector and the commercial and services sector. In the countries analyzed, an increase in GDP causes an increase in the price of energy in the industrial sector. With more CO2 emissions and a rise in the international price of oil, the annual average price of the industrial sector decreases.
