  • 독일은 환경 친화적이며 지구온난화현상에 직접적으로 영향을 미치는 이산화탄소 배출을 억제하는 방향으로 에너지정책을 실시하고 있다. 이를 기초로 환경 및 에너지 기술개발을 통한 지속가능한 성장정책을 실시하여 왔다. 따라서 독일의 에너지정책과 지속성장정책의 핵심을 이루는 요소는 재생에너지개발 보급제도, 생태적 에너지세, 배출권 거래제도 등이라고 할 수 있다. 특히 재생에너지 개발 및 보급을 통하여 화석연료 사용을 최소화하고 동시에 화석에너지 사용으로 인한 탄소배출비용을 지불하게 하는 탄소세 및 배출권거래 제도를 실시하여 재생에너지개발을 정책적으로 지원하고 있다. 본 논문은 재생에너지정책을 추진하면서 재생에너지 사용을 실질적으로 증가시키고 경제성장을 달성하여 환경에 미치는 부정적 영향을 최소화 하면서 지속가능한 발전이 현실적으로 가능한지에 대해 독일의 정책사례를 중심으로 한 조사 및 분석에 관한 연구이다. 실제로 경제성장을 위한 증가하는 에너지소비를 재생에너지로 대체할 수 있거나 경제성장을 달성하면서도 에너지소비가 증가하지 않는다면 환경에 부정적인 영향을 미치지 않고 지속가능한 성장을 달성할 수 있다. 이러한 전제조건을 충족시키는 모델사례가 독일의 에너지정책과 지속가능발전전략이며 이를 정책과 전략으로서 논리적으로 증명하는 것이 본 논문의 목적이다.

  • Cameroon is a lower middle-income country with a population of 25.87 million inhabitants distributed over a surface area of 475,442 ㎢. Cameroon has very rich potentials in renewable energy resources such as solar energy, wind energy, small hydropower, geothermal energy and biomass. However, renewable energy constitutes less than 0.1% of energy mix of the country. The energy generation mix of Cameroon is dominated by large hydropower and thermal power. Cameroon ratified the Paris Agreement in July 2016 with an ambitious 20% greenhouse gas (GHG) emission reduction. This study attempts to investigate some renewable energy deployment policy-instruments that could enable the country enhance renewable energy deployment, gain energy independence, fulfill Nationally Determined Contribution (NDC) and achieve Sustainable Development Goals. It begins with an analysis of the status of energy sector in Cameroon. It further highlights the importance of renewable energy in mitigating climate change by decarbonizing the energy mix of the country to fulfill NDC and SDGs. Moreover, this study proposes some renewable energy deployment policy-solutions to the government. Solar energy is the most feasible renewable energy source in Cameroon. Feed-in Tariffs (FiT), is the best renewable energy support policy for Cameroon. Finally, this study concludes with some recommendations such as the necessity of building an Energy Storage System as well a renewable energy information and statistics infrastructure.

  • 지난 세기 동안 무분별한 화석자원의 남용과 중국 등 개발도상국에서의 수요급증은 불안정한 유가문제를 야기하였고, 막대한 양의 비가역적 이산화탄소 배출은 지구온난화 문제를 발생시켰다. 이러한 문제를 해결하기 위하여 석유자원을 대체할 수 있는 재생 및 지속사용 가능 자원에 대한 관심이 커지고 있다. 본 논문에서는 재생 및 지속사용 가능 자원으로서 식물성 바이오매스 공급원을 활용하여 석유화학제품 대체하고자 하는 연구개발 동향을 접착소재의 관점에서 고찰하였다.

  • This paper aims to make a feasibility study and to propose a master plan for the development of "integrated ocean energy utilization system", which utilizes various renewable ocean energies. Fossils energy, as the most important energy resources which are inevitable for the living and industrial development, becomes exhausted and its consumption creates serious environmental problem. It is important to utilize renewable ocean energy for a sustainable and environmentally friendly development. We survey the integrated utilization of ocean energy based on surveyed energy density distribution and propose concepts of integrated ocean energy utilization plant for both onshore and offshore system. The results of this study can support national effort for renewable energy development utilizing integrated ocean energy and refer as a guideline for the technical development of sustainable integrated ocean energy.

  • This study explored the potential and implementation of renewable energy sources in Sri Lanka, focusing on the theoretical potential of solar and wind energy to develop self-reliant energy models. Using advanced climate data from the European Centre for Medium-Range Weather Forecasts and Global Solar/Wind Atlas provided by the World Bank, we assessed the renewable energy potential across Sri Lanka. This study proposes off-grid and minigrid systems as viable solutions for addressing energy poverty in rural regions. Rural villages were classified based on solar and wind resources, via which we proposed four distinct energy self-reliance models: Renewable-Dominant, Solar-Dominant, Wind-Dominant, and Diesel-Dominant. This study evaluates the economic viability of these models considering Sri Lanka's current energy market and technological environment. The outcomes highlight the necessity for employing diversified energy strategies to enhance the efficiency of the national power supply system and maximize the utilization of renewable resources, contributing to Sri Lanka's sustainable development and energy security.

  • In the recent modernized world, utilization of natural resources (renewable & non-renewable) is increasing drastically due to the sophisticated life style of the people. The over-consumption of non-renewable resources causes pollution which leads to global warming. Consequently, government agencies have been taking several initiatives to control the over-consumption of non-renewable natural resources and encourage the production of renewable energy resources. In this regard, we introduce an IoT powered integrated framework called as green home architecture (GHA) for green score calculation based on the usage of natural resources for household purpose. Green score is a credit point (i.e.,10 pts) of a family which can be calculated once in a month based on the utilization of energy, production of renewable energy and pollution caused. The green score can be improved by reducing the consumption of energy, generation of renewable energy and preventing the pollution. The main objective of GHA is to monitor the day-to-day usage of resources and calculate the green score using the proposed green score algorithm. This algorithm gives positive credits for economic consumption of resources and production of renewable energy and also it gives negative credits for pollution caused. Here, we recommend a green score based tax calculation system which gives tax exemption based on the green score value. This direct beneficiary model will appreciate and encourage the citizens to consume fewer natural resources and prevent pollution. Rather than simply giving subsidy, this proposed system allows monitoring the subsidy scheme periodically and encourages the proper working system with tax exemption rewards. Also, our GHA will be used to monitor all the household appliances, vehicles, wind mills, electricity meter, water re-treatment plant, pollution level to read the consumption/production in appropriate units by using the suitable sensors. These values will be stored in mass storage platform like cloud for the calculation of green score and also employed for billing purpose by the government agencies. This integrated platform can replace the manual billing and directly benefits the government.

  • A macroeconomic minimodel was simulatedto suggest the public for sustainable us of Nakdong River Basin. The minimodel for the simulation shows the interrelationships between natural environment and economic activity. Topsoil, water, economic assets, and money stock are plotted for 300 years, beginning with 1996 in each simulation. The computer simulation runs suggest that the Nakdong River Basin system in the near future may strongly be influenced by the favorable availability of outside resources, while the economic assets and money stock may be declined by indigenous environmental stock depletion. The simulation run made under the constant decrease in systems purchased inputs with investment ratio of developed country and for sustainable use. The results of simulation shows the recover of natural environment and decrease of economic activity under these condition. Therefore, the economic structure of Nakdong River Basin should be transformed from the present industrial structure to the social-economic structure based on an ecological-recycling concept which depend on renewable resources rather than industrial structural which depend on outside resources.

  • 본 논문은 수요 자원으로 활용이 가능한 조명제어 시스템을 연구하였다. 기존의 조명제어 알고리즘은 에너지수요에 관계 없이 에너지량을 절감하거나 수요자원으로 활용하기 위하여 수용가의 불편을 감수하면서 강제적으로 조명을 차단하는 알고리즘을 사용하고 있다 이 논문에서는 사용자의 근무 괘적성을 유지하면서도 수요자원으로서 활용이 가능한 새로운 조명제어 알고리즘을 제시하고, 시뮬레이션을 통하여 유용성을 검증하였다.

  • 육상식물 재배면적과 바이오매스 자원이 부족한 우리나라는 바이오 에너지 원료의 다변화가 시급하며, 3면이 바다로 싸여 자원이 풍부한 해양환경을 이용한 바이오 에너지 생산기술 및 이를 통한 $CO_2$ 저감 방안은 매우 효과적인 대안이 될 것이다. SSaM-GG를 통해 $CO_2$ 흡수율이 높고 해바라기의 30배 많은 양의 기름 추출이 가능한 해조류의 바이오 에너지화에 대한 지속가능한 발전을 기대한다.
