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.

Analysis of energy consumption in Finland based on the selected economics indicators

ABSTRACT Energy is one of the main inputs of productions. Therefore, national policies have emphasised on accessibility, availability, and affordability of energy supply. This is very important for energy importers, in particular countries with high dependency on industrial products. Finland is one of such countries that has high-energy consumption due to its cold climate, energy-intensive industries, and low population density. Therefore, security of energy supply to respond domestic consumption is one of the main concerns of the Finnish government. To have a resilience energy supply, it is necessary to understand the energy system in Finland. Energy modelling is a tool that helps policy-makers and researchers to understand the fluctuations and changes in the energy system. This research is to investigate the relationship between energy consumption and selected macro-economic factors in Finland. Therefore, energy consumption in each sector is analysed and the importance of renewable energies is also considered. Finally, a regression model is presented to predict energy consumption.

ABSTRACTUtilization of renewable energy technologies is one of the strategies of the governments in order to increase the level of energy security. One of the main renewable energy resources with fast utilization growth is wind power. However, development of wind power is highly depended on its related technologies. Therefore, wind power technology forecasting is an indispensable requirement to understand how each of the wind energy domains will improve in the future. This research is to focus on the analysis of wind power technologies based on the technology life cycle approach. The contributions can help researchers, technology futurists, and policy makers to focus better on the related R&D and utilization policies.

Social Acceptance of Renewable Energy in Developing Countries: Challenges and Opportunities

ABSTRACTUtilization of renewable energy technologies has short-term, middle-term and long term interests. Since the portion of renewable energies have to increase 10% till 2025, legislating relevant policies for increasing the portion of these energies is essential. This article reports studies about the social acceptance level of renewable energies in a selected developing country by using social acceptance pyramid. First, the identified indicators are weighted based on the circumstances of renewable energies. After that, the selected renewable sources, wind, solar, and geothermal, are ranked based on the indicators and analytical hierarchy process. The research results indicate that wind energy has the better social acceptance position than solar and geothermal energies. Finally, some polices are suggested for increasing the acceptance level of all renewable energies in developing countries.

Strategic Analysis of Iran's Energy System

ABSTRACTDue to the importance of energy to societies, analysis of local, regional and national energy systems at different levels is salient for researchers and policy makers. This article considers Irans extraction, processing, conversion, transmission, distribution, and consumption of energy. Iran is one of the worlds fastest growing energy consumers and its economy is highly dependent on energy exports. The patterns of Irans present energy system impact its economy and development. Our research assesses the energy system in Iran by identifying and analyzing its strengths, weaknesses, opportunities and threats (SWOT). The article considers these from internal and external perspectives and concludes that energy plays an important role in policy and development. This assessment can help policy makers and researchers identify challenges and create suitable and robust strategies.

Science and technology diplomacy: a framework at the national level

Purpose Science and technology diplomacy (STD) is an emerging area in the field of public policy and technology management. The purpose of this study is to overview the concept of STD based on the two approaches “Science and Technology” and “Diplomacy” to explain its necessity for Non-Aligned Movement member countries. Design/methodology/approach To design the work, principal domains and sub-domains of STD are identified based on the thematic analysis. By using MAXQDA software, the initial codes are analyzed and validated for the case study. Then, six areas and 29 sub-areas are identified based on the fuzzy Delphi and the framework is designed. Findings STD is defined from six scopes, including political, economics, law and legal issues, social sciences, philosophy and science and technology. Each scope has its own mechanism that is discussed in the article. Originality/value This work is one of the first in the literature of science and technology policy making.
