The integration of renewable energy (RE) into the overall energy mix of Caribbean nations has been increasing in recent times. The volatile nature of the carbon-based industry through fluctuations in prices of fossil fuel based-products renders it necessary to promote an aggressive energy profile transition to renewable energy, as this is crucial to energy security in these vulnerable Small Island Developing States (SIDS). The nation of Barbados has notably understood this reality and, as such, its government has endorsed the approach of 100% RE implementation by 2030. This paper explores three distinctive annual growth rate (AGR) scenarios to assess the impact on the expected power generation, economic and environmental parameters through the period of 2019-2030. Notable findings at a high case scenario for 2030 (at an AGR of 3%) projects a power generation of 1.343 Tera-watts-hour (TWh), which will displace 790,500 barrels of oil equivalent (boe), resulting in an abatement of approximately 0.95 million tons of carbon dioxide into the atmosphere.

Renewable Energy Generation

Renewable energy generation is no more an alternative rather it becomes a choice for the power generation to meet the upcoming energy demand. Considering the non- renewable energy unavailability, as well as, the environmental impact, renewable energy should be the first choice. Most of the power generation in Bangladesh comes from nonrenewable energy and a noticeable amount of energy is imported from abroad. As a developing country, it is not cost-efficient and never ensures energy security. To ensure long-term energy security, it is time to shift power generation from nonrenewable to renewable energy generation. This paper presents an approximate calculation for the renewable power generating plant cost and returning year. The cost calculation is done in the context of Bangladesh.

Introduction. The topic of renewable energy today is one of the most relevant and requires consideration from the point of view of all components of this process, namely economic, financial, environmental, technological, and others. The transition to renewable energy is already irreversible today since natural resources are depleted, fuel prices are the subject to significant fluctuations, and the stable growth of the national economy is ensured by energy security. The purpose. The purpose of the article is to analyze the volume of global energy consumption, to analyze the impact of the introduction of renewable energy sources on the development of the national economy, to ensure energy security with the depletion of hydrocarbon resources and a slight diversification of their suppliers. Results. Today the Ukrainian economy is the most energy-intensive. Unstable energy prices are a threat both to the global economy and to each country separately. Therefore, in the event of a decrease in the supply of traditional energy resources, the importing countries experience the greatest difficulties. The existing tendency in Ukraine to increase the consumption of traditional energy sources, combined with the absence of a targeted policy aimed at reducing the volume of environmental pollution, will lead to an increase in negative economic consequences. The advantage of renewable energy sources is their equal distribution throughout the country (with the exception of water resources). This feature leads to the formation of one of the main characteristics of power systems based on renewable energy sources, namely, their decentralization. It should be borne in mind that the world energy market is made up of state and non-state participants. Non-state participants are showing an upward trend. However, the state should have the greatest influence on the national energy sector. Renewable energy is an area that, in the Ukrainian context, depends on state support, namely economic and administrative incentives. The dynamics of the development of renewable energy should be combined with the balanced development of the fuel and energy sector in Ukraine. Conclusions. The process of development and transition to renewable energy needs a systematic approach. Both qualitative and quantitative approaches are needed to assess the transition to renewable energy. An effective strategy for the transition to the introduction of renewable energy technologies should be justified by economic feasibility. The transition from traditional energy to renewable sources should lead to energy security, which contributes to stable economic growth, political independence, and improving the quality of the environmental component.

Feed In Tariff

Although most countries in the world have been trying to introduce renewable energy into their power supplies to address issues related to the environment and energy security, the Middle East has the lowest overall renewable energy capacity in the world. However, there is currently a trend of accelerating renewable energy deployment with increased investment in the region for the purposes of improving energy security and independence and promoting long-term social and economic benefits. This study aims to examine the impact of implementing a feed-in tariff (FiT) in Abu Dhabi, United Arab Emirates. After a simulated test, it was found that the levelized cost of electricity (LCOE) and the current average unit cost of electricity were considerably divergent. That is to say, a large extra cost is incurred in order to deploy renewable energy in Abu Dhabi. In this context, the effectiveness of implementing a FiT in Abu Dhabi is confirmed. Furthermore, an estimation of the size of the renewable energy surcharge indicated that the impact of implementing a FiT would be enormous. For example, if the target rate of deploying renewable energy is set at 7%, a renewable energy surcharge equivalent to approximately one third of the total turnover of the electricity sector should be additionally imposed. It follows that the electricity rate will be raised by about thirty percent on average, unless subsidies are provided by the government.

The Impact

In an era of energy transition involving an increase in renewable energy and a reduction in coal-fired power generation and nuclear power generation, the role of combined heat and power (CHP) as a bridging energy is highly emphasized. This article attempts to look empirically into the impact of increasing the share of renewable energy in total electricity generation on CHP share in total electricity generation in a cross-country context. Data from 35 countries during the period 2009–2015 were used, and the least absolute deviations estimator was applied to obtain a more robust parameter estimate. The results showed that a 1%p increase in the share of renewable energy significantly increased the CHP share by 0.87%p. Therefore, the hypothesis that CHP serves as bridge energy in the process of energy transition was established.

Technology roadmaps are critical for decisions pertaining to technology development. They have been utilised in the renewable energy sector to assist in filtering alternative technology options in order to support energy policy formulation, energy security and energy independence, among others. However, solar aided power generation is a recent concept and no roadmap has been developed for the technology as yet. This paper thus reviewed the literature related to roadmapping with the aim of understanding the methods and tools that have been utilised in other settings. Informed by the literature, a conceptual framework was developed, which was further utilised for the initial analysis for developing a roadmap for solar aided power generation in South Africa. Generally, it would be beneficial for South Africa to integrate solar aided power generation within its current Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) or the National Treasury Public-Private Partnership (PPP) programme. However, it should be noted that this is only feasible in the short- and medium-term. In the long-term, there is a need to support stand-alone solar thermal technologies.

The Antarctica Showa Base has been powered primarily by diesel power generation. However, heavy oil fossil fuel is used for power generation by diesel generators. The Showa base is located in Antarctica, so there is heat demand throughout the year. Therefore, the capacity of transportation of fuel and emissions of carbon dioxide has become an issue. For these reasons, the construction of clean energy systems using renewable energy in order to locally produce energy for local consumption is being planned. In this study, we will design a microgrid based on the introduction of renewable energy (photovoltaics generation and wind power generators) and solid oxide fuel cell (SOFC), which does not emit carbon dioxide during power generation and can use heat cascades. However, there is a risk of a power failure because the power quality decreases with the introduction of renewable energy. In this paper, we clarified the introduction rate of renewable energy with the lowest frequency fluctuation and clarified the introduction limit of renewable energy in summer and winter.

The Impact

AbstractIn recent years China's national oil companies (NOCs) have proactively ventured abroad to look for more fossil fuel supply. Despite the divided views on their foreign energy quest, previous studies tend to consider the Chinese government and its NOCs to be a monolithic organism, and explicitly or implicitly presuppose that the Chinese NOCs' foreign energy quest could enhance China's energy security. This is, however, an untested hypothesis. To fill the gap, this article assesses the impact of Chinese NOCs' foreign energy quest on the country's energy security. Findings show that the Chinese NOCs have made some progress in their foreign energy quest, which contributes to their coffers and reserves, but that does not mean that China's energy security is greatly enhanced; in particular, the diversity and reliability of China's foreign oil sources are questionable.

The Impact

Since the turn of the century, gas has been highlighted as the transition fuel to a lower emissions world, and, in 2011, the International Energy Agency published a special report entitled ‘Are we entering the golden age of gas’, which indicated that gas use could rise by over 50% to provide more than 25% of world energy demand by 2035. Even though gas use has risen in tandem with the increase in renewable energy, over the past decade, coal has been the fastest growing fuel because developing countries choose cheap power to provide their growing energy needs. Gas has been, and continues to be, subject to a green, cheap squeeze; squeezed by cleaner renewables on the one hand, and cheaper coal on the other. This paper will look at the impact that increasing amounts of renewable energy has on existing power generation and supply systems, and provide insights into the potential range of outcomes in emission levels, and the need to not only discuss renewable energy target, but to also understand the total energy mix, and the need to reposition gas from a transition fuel to the natural long-term companion of renewables.
