The Cost

Solar energy is the most abundant, useful, efficient, and environmentally friendly source of renewable energy. In addition, in recent years, the capacity of photovoltaic electricity generation systems has increased exponentially throughout the world given an increase in the economic viability and reliability of photovoltaic systems. Moreover, many studies state that photovoltaic power systems will play a key role in electricity generation in the future. When first produced, photovoltaic systems had short lifetimes. Currently, through development, the technology lifecycle of photovoltaic systems has increased to 20–25 years. Studies showed that photovoltaic systems would be broadly used in the future, a conclusion reached by considering the rapidly decreasing cost of photovoltaic systems. Because price analysis is very important for energy marketing, in this study, a review of the cost potential factors on photovoltaic panels is realized and the expected cost potential of photovoltaic systems is examined considering numerous studies.

Combining Information

Pests and diseases introduced from other countries are known to pose a threat to trees, woods and forests in many locations throughout the world. Once introduced they can be spread inadvertently by countryside visitors hiking, biking or riding along paths and trails through wooded areas. Engaging and communicating with these groups of countryside users to encourage and facilitate positive biosecurity behaviours is crucial for the future resilience of trees, woods and forests. This review draws on literature outlining principles for stakeholder engagement in forestry as well as evaluations of biosecurity campaigns from around the world. Key points are briefly presented for communicators aiming to encourage better biosecurity in the countryside. These include, the need to design campaigns based on the values and motivations of recreationists, using trusted information sources and understanding the importance of combining information with facilities so as to reduce the cost (in terms of effort and inconvenience) to hikers and other countryside users.

Substantial Rise

The abundance of the worldwide resources of natural gas and its qualities as a “clean” fuel make it a major energy option for the future. However, the increasing distance of resources in relation to the major consuming zones should bring about a considerable development of international gas trade and also a very substantial rise in the cost of future supplies to major markets. Will these markets accept a new scale of value for natural gas in relation to other fossil fuels in order to ensure the economic viability of the formidable investments required in the coming decades is the most critical question of the gas industry, among many other technical, economic and political issues.

The Impact

The market for electric vehicles (EVs) has grown with each year, and EVs are considered to be a proper solution for the mitigation of urban pollution. So far, not much attention has been devoted to the use of EVs for public transportation, such as taxis and buses. However, a massive introduction of electric taxis (ETs) and electric buses (EBs) could generate issues in the grid. The challenges are different from those of private EVs, as their required load is much higher and the related time constraints must be considered with much more attention. These issues have begun to be studied within the last few years. This paper presents a review of the different approaches that have been proposed by various authors, to mitigate the impact of EBs and ETs on the future smart grid. Furthermore, some projects with regard to the integration of ETs and EBs around the world are presented. Some guidelines for future works are also proposed.

Electrical power is a resource humans heavily rely on, and it has become a basic human need. Today, the major sources of electricity generation are fossil fuels, renewable energy, and nuclear power. This paper concentrates on electricity generated through nuclear power and compares it to the other electricity generation technologies. The objective behind this paper is to discover the impact that nuclear power has on the total electricity generated in Canada, and in addition on a global scale. The paper presents the current role that nuclear power plays in the global electricity generation, and also the expansions that need to be made in the nuclear power industry to fulfill the future electrical power demands. A number of projections have been made based on the current rate of nuclear reactors being put into operation, which is approximately 4 reactors per year, and current term of reactor operation, which is 45 years. These projections were made for the nuclear power in the world. A major outcome of this analysis projects that between 2030 and 2035, the number of operating nuclear reactors in the world can drop by 50%. If this dangerous trend is not addressed, we can lose a viable, and reliable source of energy. The datasets that were analyzed during the process were taken from multiple open literature sources such as journals, reports, and online databases. The paper presents a comparison between nuclear power and other energy sources, and the positive impact nuclear power can have on the world if needed advancements were made in building new nuclear power plants.

Economic Boom

ABSTRACT Despite the global setbacks, in recent times Africa's economy has generally managed to grow, with an average GDP increase of about 5%. Africa's economic growth prospects have been the talking point in recent economic fora. This growth however, has been inhibited due to the insufficient access to reliable electricity for most of Africa. The future outlook for this yet looks set to change dramatically, with African countries diversifying their energy portfolio. A good case in point is in Kenya. As of March 2015, Kenya's effective installed electricity capacity was 2177.1 MW, with supply primarily being sourced from hydroelectric and thermal sources. With connectivity to the national grid at just 28%. As of 8th June 2016, Kenya was the 4th largest geothermal energy developer in the world, possessing the largest geothermal plant in the world, capable of providing almost 20% of the nation's total power capacity (280MW Olkaria plant). Geothermal is just the tip of the iceberg, for years wind energy has contributed just 5.1MW to the national grid, but with the construction of the lake Turkana power project set to come online by July 2017 injecting 310MW or about 18% of current installed electricity generating capacity, a different ball game is about to commence. With Kenya's innovation and IT scene making waves worldwide, the incorporation of this into the energy scene has been quite successful with the M-Kopa model the latest crown jewel. Solar century and London distillers have held engagements to build the largest solar roof project in East Africa, almost 1 MWp. Kenya is currently the world leader in number of solar power systems installed per capita. With the Lamu coal power plant set to add 981.5 MW to the grid and Kenya aiming to replace some fossil fuel, electricity capacity, with nuclear energy (it is currently evaluating its grid system before considering the generation options). These are key stepping stones for an energy boom with an unequivocal industrial and economic boom. Considering the major infrastructural projects of rail, road and pipeline being undertaken with these energy prospects, the future is only brighter. The fact that most of the developed world economies are slowing down only serves to fuel the fact that Kenya and Africa's economic revolution is inevitable. A key indication that the next decades belong to Africa, at least from an economic stand point.

Significance With populations growing by 3-4% annually, physical infrastructure requires significant expansion. Mobile telephony has been a major success, but there is much to be done to improve urban transport, long-distance roads and electricity generation. Rising insecurity compounds these challenges. Impacts With populations rising fast, there is a continual need to build more schools, health clinics and other key service premises. Efficient ports and modern transport links can bolster the cost-competitiveness and economic viability of industrial activity inland. Rising insecurity will prevent maintenance of infrastructure in affected areas.

Stimulus Package

The economic crisis erupting from inadequate regulation of reckless banking practices in 2008 was correctly met by Keynesian-style stimulus packages in governments around the world. These measures were successful when they were sufficiently large, properly focused, and implemented promptly. Where these conditions were not met, as in the case of Thailand, the results were unimpressive and the problems not dealt with properly. However, the Thai version of the second part of the stimulus package, Thai Khem Kaeng, had in fact quite a different purpose and appears to have been intended to boost the popularity of the government at the cost of making unsustainable and uncosted deficits for the future. The lack of coherence at the economic planning centre of government and its questionable methods suggest that Thailand has continued the longstanding policy of making economic decisions for non-economic reasons.

Abstract. This research took place just after the end of the protests following the killing of a 16-year-old boy by a policeman in Greece in December 2008. Participants (N = 224) were 16-year-olds in different schools in Attiki. Informed by the Politicized Collective Identity Model ( Simon & Klandermans, 2001 ), a questionnaire measuring grievances, adversarial attributions, emotions, vulnerability, identifications with students and activists, and questions about justice and Greek society in the future, as well as about youngsters’ participation in different actions, was completed. Four profiles of the participants emerged from a cluster analysis using representations of the conflict, emotions, and identifications with activists and students. These profiles differed on beliefs about the future of Greece, participants’ economic vulnerability, and forms of participation. Importantly, the clusters corresponded to students from schools of different socioeconomic areas. The results indicate that the way young people interpret the events and the context, their levels of identification, and the way they represent society are important factors of their political socialization that impacts on their forms of participation. Political socialization seems to be related to youngsters’ position in society which probably constitutes an important anchoring point of their interpretation of the world.

Second Wave

With signs of normalization seemingly in place in the world economy, a number of problems show the possibility of aggravation in the future. The volume of derivatives in American banks grows significantly, high risk instruments are back in place and their use becomes more active, global imbalances increase. All of the above requires thorough approaches when creating mechanisms which can neutralize external shocks for the Russian economy and make it possible to develop in the new post-crisis environment.
