... These entities can accelerate the pace and support the more aggressive path that the United States has begun to take, that is, the path to a new energy economy. But it is not immediately possible (Ross et al., 2016). Azzopardi T pointed out that Chile's economic slowdown in the past three years may inhibit the prosperity of energy investment, but after ten years of repeated crises, the future of the country's energy supply looks safe, thanks to its huge renewable energy resources and new the links with natural gas-rich Argentina (Baiman, 2021). ...
The advent of the era of big data not only enables us to have more information that we can use, but also creates conditions for us to create and disseminate information in a timely manner. This article systematically sorts out and analyzes the overall development and investment of new energy in China, as well as the current new energy incentive policies implemented, and points out the problems in the development of new energy. On this basis, the technical risks, policy risks, and market risks faced by this new energy investment are analyzed, and a risk evaluation model based on DHGF and entropy technology is established. It can help investors identify potential investment opportunities. Investors can use the option of investment projects granted by real options to reduce the impact of uncertainty, thereby increasing the value of the company, and making more scientific and reasonable investment decisions. The experimental results of this article show that since 2009, stock market financing has become a financing channel favored by developers.
... Concerns regarding negative environmental impacts of human activities, energy security and sustainability for future generations have been at the forefront of the agenda of many countries and organizations around the world. Such is the case of the European Union (EU) [1][2][3][4] and other major players in the global energy market, including China [5][6][7] and the United States [8,9]. The policies and development directives established by them are driving an energy transition process characterized by the need for cleaner and renewable energy sources (RES). ...
Within the scope of a changing energy market, wave energy has yet to reach a level of commercial viability that enables it to become competitive with alternative energy sources, both renewable and non-renewable. Despite the well-known advantages inherent to the resource, there are several challenges that must be overcome before wave energy gains a relevant share of the global energy market. While near-commercial stages of development
are still outside the reach of most wave energy converters, it is important to find new perspectives that facilitate the development process and improve the chances of a successful deployment and operation. In this paper, a review of synergetic technologies with the potential for hybridization and/or co-location with wave energy converters
is presented. Potential applications of wave energy conversion devices, within the context of nearshore and offshore niche markets that minimize/eliminate, respectively, mainland grid connection and inherent costs are also discussed. It is found that mutual gains can be attained from this complementary approach, namely in terms of infrastructure sharing, critical component protection, introduction of a beneficial shielding effect, energy storage upgrading, coastal erosion mitigation and electricity supply to various marine mobile platforms for different offshore and nearshore activities, amongst others.
... Governments are actively leading the development of alternative energy sources; energy problem is increasingly becoming the focus of international attention [2]. In the past decade, England have achieved the largest increases in renewable energy share [3], the usage of renewable energy resources is increasing in U.S. energy production, and reductions in coal usage through cheaper, cleanerburning natural gas assuming its share of energy production, and it's in the process of meeting energy efficiency targets to reduce CO2 emissions by 30 percent utility sector by 2030 [4]. ...
... For this reason, potential users of electric vehicles often ask for public charging facilities before buying vehicles, so it should increase attentions on battery sizes and power rates in the future [32], developing new business models of charging infrastructures, and the charging price should be considered more carefully at the same time [33]. Thirdly, cities are responsible for more than 60 percent of the total global energy consumption and approximately 70 percent of greenhouse gas emissions [4]. Faced with energy contradictions caused by increasing need for resources but with severe deficiency, the use of clean resources should be upgraded within the national security strategies. ...
... Moving towards this goal, European countries face market barriers, and also barriers related to behavioral and social aspects of energy efficient policy ( Kern, Kivimaa, & Martiskainen, 2017;Bukarica & Tomšić, 2017;Gooding & Gul, 2017). The United States declared the goal of 50% reducing greenhouse gas emissions by 2030, but some institutional barriers nowadays are challenging in achieving this goal ( Romanov, 2014;Hargadon & Kenney, 2012;Lee, Kim, & Chong, 2015;Ross, Sperling, & Guhathakurta, 2016). The task of increasing the energy efficiency in the regions of Russia is important due to widespread wasteful use of energy resources in production, maintenance and consumption spheres. ...
Nowadays budgetary funds still prevail among sources of financing of the projects in the area of increasing the energy efficiency of the regional economy in the Russian Federation. For example, in the Tver region in 2016, 82% of the projects for the modernization of the heat supply infrastructure and 100% for the modernization of the electricity supply infrastructure were implemented at the expense of the budget. At the same time, there is a decrease in the total amount of state financing of energy efficiency projects due to a high proportion of the budget deficit of the subjects of the Russian Federation. According to the agency ACRA (information dated April, 12, 2017 at www. acra-ratings.ru), 58 out of 85 regional budgets for 2017 were accepted with a total deficit of 193 billion rubles. At the same time, the urgency of applying organizational and financial mechanisms for the implementation of energy efficient projects involving alternative financing is growing. The article systematizes the views on the perspective mechanisms for implementing projects in the field of increasing the energy efficiency of the regional economy, including taking into account the analysis of problems of their application in the example of the Tver region. The authors studied existing organizational and financial mechanisms for energy-efficient projects, including public private and municipal private partnerships, and the Local Initiatives Support Program. © Marina Tsurkan, Svetlana Andreeva, Maria Lyubarskaya, Vadim Chekalin, Galina Lapushinskaya, 2017.
... As shown in Fig. 3, the USA currently has the highest amount of non-hydro RE-based generation in the world (as at 2013), however total energy generation is still dominated by coal and gas with RE making up just 13% [36]. In order to increase the deployment of RE, the Environmental Protection Agency (EPA) Clean Power Plan aims to achieve a 30% reduction in GHG emissions in the utility sector by 2030 [37]. ...
... In order to increase the deployment of RE, the Environmental Protection Agency (EPA) Clean Power Plan aims to achieve a 30% reduction in GHG emissions in the utility sector by 2030 [37]. US energy policy is developed and implemented independently at both state and federal levels [38], and the new Final Rule for the EPA Clean Power Plan will allow each state to tailor their response according to their own energy profiles [36]. Additionally, some states have their own energy targets which meet or exceed the EPA requirements [39]. ...
... Additionally, some states have their own energy targets which meet or exceed the EPA requirements [39]. US policy recognizes that approximately 60% of energy consumption and 70% of GHG emissions are occurring in cities, and is developing a 'megaregion' based response to reducing these emissions and innovating within the energy space [36]. One of the RE growth areas in the US is distributed generation solar (electricity that is produced at or near the point where it is used, rooftop or groundmounted [40]), predominantly rooftop PV. ...
This paper investigates the precedents, policies and factors relevant to a successful energy regime transition which may be applied in the Japanese case, through a review of national leaders in renewable energy deployment. The examples of Germany, Italy and Spain are of particular note for their progress along the transition pathway toward a low carbon energy regime. Transition theory is used as a framework to enable this assessment, and exogenous impacts specific to Japan such as recent and ongoing market liberalization and the Fukushima nuclear incident are considered as pertinent factors which impact upon the transition landscape. Through a comparative assessment of policy approaches, technologies deployed, and social factors impacting upon deployment, lessons are drawn for comparison with current Japanese transition progress, identifying factors critical to the future estimation of the Japanese transition pathway. Future energy transition pathway projections will need to incorporate policy approaches and mechanisms as well as being cognizant of Japan's geographic and cost-competitive RE resource deployment limitations. These limitations alongside existing generation assets (including nuclear energy) are expected to have a significant impact upon Japan's transition from the current pre-development phase toward take-off, acceleration and the stabilization of a new, low-carbon energy regime.
The Korean government announced a new energy transition policy that emphasizes phasing out nuclear and coal energy and increasing renewable energy sources. However, a lack of quantitative research has resulted in dis-agreements about the most suitable energy transition strategy for Korea. To evaluate the policy, we designed a quantitative analysis that simulates generation scheduling and settlement processes in the Korean power market.
We then analyze the economic impacts, conflicts of interest, greenhouse gas (GHG) emissions, and the power system’s market price sensitivity to the price of imported liquefied natural gas (LNG) in four energy transition scenarios: i) the government’s new energy transition policy, ii) phase-out of nuclear energy, iii) phase-out of coal energy, and iv) simultaneous phase-out of nuclear and coal energy. Additionally, we evaluated the effects of coal taxation. Based on the power market simulation results, we conclude that phasing out nuclear energy with increasing taxation of coal, or only phasing out coal energy are two reasonable scenarios for energy transition in Korea. The simultaneous phase-out of nuclear and coal energy, which was originally pursued by the government, is inferior to the recommended scenarios in the aspects evaluated. Policymakers should consider these results when developing feasible energy transition scenarios.
This research investigates precedents, policies and factors relevant to a successful energy regime transition relevant to the Japanese case, through a review of national leaders in renewable energy deployment. Germany, Italy and Spain are of particular note for their progress in energy transition toward a low-carbon energy regime. The transition theory framework is utilized in this assessment, and exogenous impacts specific to Japan such as recent, ongoing market liberalization and the Fukushima nuclear indecent are considered as pertinent factors impacting upon the transition landscape. Through a comparative assessment of policy, technology and social factors which affect transitions, lessons are drawn for an evaluation Japanese transition progress, identifying factors critical to the future estimation of the energy transition pathway. Future energy transition projections will need to incorporate policy approaches and mechanisms while recognizing Japan's geographic and cost-competitive energy generation deployment limitations. These limitations and utilization of existing generation assets are expected to have a significant impact upon Japan's transition from the current pre-development phase toward take-off, acceleration and the stabilization of a new, low-carbon energy regime.
This paper attempts to explore the effect of energy construction adjustment on the energy-saving and emission-reduction (ESER) dynamical evolution system. Based on the nonlinear dynamics theory, the dynamic behavior of the novel system is discussed. The quantitative coefficients of the actual system are identified with the aid of genetic algorithm-back propagation neural network. Scenario analysis results show that, energy construction adjustment could effectively control energy intensity. To clarify this further, an example of 4D ESER system with new energy constraints is demonstrated. Investigation results show that, government control can effectively control energy intensity, while brings inhibiting impact on economic growth and people’s livelihood. Economic investment is the key variable affecting energy construction adjustment and ESER, the ESER system will crash when the investment is too low. Energy construction adjustment could effectively reduce energy intensity. However, the ESER system will also crash if the development of energy construction adjustment is too fast. The interesting thing is that the ESER system should be pulled back to steady state as the investment getting bigger. Energy intensity could be controlled in expected range by taking adequate measures. Full use of the role of energy structure adjustment should be made to promote the development of new energy, while government control is used only when necessary.
