Hydropower as a renewable energy source is a serious future alternative to organic fuel power and environmental protection. Its use is least damaging to the environment in comparison to thermal and nuclear power. Hydropower is a constant generating source and a type of energy that yields most return. Based on this approach, the article assesses the hydropower development, reveals the reasons behind the hindrance of renewable energy source development, evaluates the tendencies and development prospects, draws the conclusions and presents the recommendations. This article reflects the concept of the latest findings of scientific research and practical interface. Planning, design, construction and operation of hydropower facilities, must be determined on how they may affect the natural state of water bodies, it is imperative to analyze and assess the environmental protection effectiveness. Natural water bodies should not be modified without an environmental impact assessment

Policy Incentives

The Great East Japan Earthquake (GEJE) and Fukushima nuclear disaster that occurred in 2011 gave a sharp reminder to Japan’s energy security to reconsider the reduction of nuclear power dependence with a better energy mix. We use a recursive CGE model based on Japan’s renewable energy input–output model to analyze the energy composite of power generation and consumption to investigate cost-effective policy incentives to achieve an optimal energy mix to reduce the nuclear power dependence to less than 5% within 10 years. Moreover, we create scenarios of: (1) nuclear power decommission, (2) renewable energy promotion and (3) virtual power plant (VPP) implementation with public R&D expenditure and power infrastructure investment. The simulation results show that renewable energy could gradually replace nuclear power with capital-use subsidies. Under the direction of nuclear power decommission, the VPP installation could reduce the fiscal cost of wind power by 13%, solar energy by 8% and the social cost by 36%. We provide empirical evidence that the implementation of VPP should be promoted in addition to the renewable policy promotion policy to facilitate power allocation and overcapacity problems better.

According to the Eurostat database, the percentage of renewable energy sources in the energy mix of the EU is increasing year after year (www.europa.eu/eurostat). In 2018, the values reached 73% in neighboring Austria (48% in Croatia, 42% in Romania, 32% in Slovenia and 21% in Slovakia), Hungary now stands at 8%. Wind energy is the leader in the renewable energy structure of the EU countries (35, 8% in 2018), since the construction of wind farms is prohibited in our country, one of the main objectives of research is to examine our energy structure. Our last position in renewable energy in 2020 prompted the government to develop a new climate strategy (mekh.hu/nemzetienergiastrategia2030). According to the new strategy, Hungary is estimated to be climate and carbon neutral by the end of the decade. Among the alternative sources of energy, solar energy is becoming the favorite, and our article points out why other forms of energy are being overshadowed. Analyzing the changes in the country’s future energy mix, it can be said that it will be based essentially on nuclear power and electricity from Russia’s electricity grid. However, due to the drastic drop in the cost of solar panels in the energy mix of households, solar energy has become a favorite of renewable energy sources. In the climate strategy, the government plans to create 8,000 MW of solar energy by 2050, which will be mainly used in households, municipal buildings, and tourism.

Abstract The interest in small modular reactors worldwide has been increasing due to flexibility in the power generation for more comprehensive users and applications. Small Modular Reactors or SMRs can be the primary choice for Indonesia provided with the geographical condition, which consists of many islands and is more flexible in construction compared to the conventional nuclear power plant. The main objective of this paper is to provide an overview projection of demand and energy mix of electrical in Indonesia 2030 with SMRs NPP in the energy mix referring to RUPTL or General Plan of Electricity Supply Indonesia. Using the end-use model, which is total electricity consumption for each electricity sector, it can be calculated how much electricity demand is from these sectors. The scenario uses RUPTL, roadmap from Energy and Mineral Resources Ministry references, and policy of no coal power plant added from 2020 onwards. The results show in 2030, Indonesia needs 577,016.2 GWh of electricity, where the household and industry sectors have the highest electricity needs, which is 44% for the household sector and 31% for the industry. The transformation projection in PLTGU or Combined Cycle Power Plants scenario also shows that without replacing the power plant, renewable along without SMRs only had ±7.49% of the total capacity mix, and the second scenario with SMRs shows that renewable energy share had 16.07%.

Diesel acts as a main energy source to complement human activities in Antarctica. However, the increased expedition in Antarctica has threatened the environment as well as its living organisms. While more efforts on the use of renewable energy are being done, most activities in Antarctica still depend heavily on the use of diesel. Diesel contaminants in their natural state are known to be persistent, complex and toxic. The low temperature in Antarctica worsens these issues, making pollutants more significantly toxic to their environment and indigenous organisms. A bibliometric analysis had demonstrated a gradual increase in the number of studies on the microbial hydrocarbon remediation in Antarctica over the year. It was also found that these studies were dominated by those that used bacteria as remediating agents, whereas very little focus was given on fungi and microalgae. This review presents a summary of the collective and past understanding to the current findings of Antarctic microbial enzymatic degradation of hydrocarbons as well as its genotypic adaptation to the extreme low temperature.

Taiwan intends to be nuclear free by 2025. This study employs the Lotka–Volterra competition model for sustainable development to analyze the emissions–energy–economy (3Es) issue to make appropriate policy suggestions for a nuclear-free transition. It also offers a new approach to naming the 3E relationship. The literature review shows that the environmental Kuznets curve accompanies the feedback and conservation hypotheses. In the 3E dynamics relationship analysis, the model shows a good mean absolute percentage error (<15%) for the model estimation. The key findings are as follows: 1) the fossil fuel-led economy exists; 2) CO2 emissions are reduced with nuclear energy consumption; 3) renewable energy is far from scale; 4) a complementary effect exists between fossil fuel and nuclear energy consumption; and 5) gas retrofitting and phasing out of nuclear seem imminent. In the energy transition, Taiwan drastically cuts nuclear energy without considering energy diversity due to which troubles might ensue. The priority issue for Taiwan’s energy mix is energy security. To deal with these concerns, this study suggests the government could improve energy efficiency, build a smart grid, develop carbon capture and storage, and reconsider putting nuclear energy back into the energy mix before renewable energy is scaled.
