The European Union (EU) aims to prepare its strategy and infrastructure for further decarbonisation of its energy system in the longer term towards 2050. Recent political discussions and research interest focus on ways to accelerate the development and deployment of low-carbon technologies with respect to the targets set for 2030 and 2050. However, the diverse options available that are to be implemented, are policy sensitive and need careful comparative assessment. This paper presents a multi-criteria approach based on an extension of the Preference Ranking Organization METHod for Enrichment of Evaluations (PROMETHEE) method for group decision-making that incorporates fuzzy set theory in order to evaluate alternative transformation pathways for achieving a sustainable energy system in EU. This assessment aims at providing a direction towards a most preferable pathway concept that should be taken into account by a future model-based analysis of the necessary transformation of our energy sector. The results obtained could support policymakers in drawing effective recommendations based on the findings. The added value of this analysis to policymakers is its contribution to plan climate and energy strategies towards a low-carbon transition pathway by using the information of this approach and prioritizing uncertainties through an environmental and energy perspective.

Low Carbon Technologies

To overcome the negative environemental impact of the actual power system, an optimal description of quasi-static electromagnetics relying on a reversible interpretation of the Faraday’s law is given. Due to the overabundance of carbon-free energy sources, this description makes it possible to consider an evolution towards an energy system favoring low-carbon technologies. The management for changing is then explored through a simplified linear-programming problem and an analogy with phase transitions in physics is drawn.

Solar energy will be an important source of energy for a sustainable energy system whether or not it is directly collected (solar thermal, photovoltaics) or indirectly collected (wind, wave, etc). This project focused on increasing the efficiency of the direct conversion of solar energy into electricity, which is also known as photovoltaics (PV). It has long been known that photovoltaic cells perform less efficiently at higher temperatures. In fact, solar modules under concentration are frequently cooled either actively or passively. The current study, however, focused on cooling modules under no concentration. The goal of the current project was to answer the question: Can the energy gained by cooling a photovoltaic module with groundwater be greater than the energy used by the cooling system and is there an economic benefit? A digital simulation of a simple photovoltaic module under groundwater cooling was performed in order to answer the research question. The simulation was performed for Phoenix, AZ and assuming certain control parameters it was found that the overall system produced over 9% more electricity than a system without groundwater cooling. While the groundwater cooled system increased overall electrical production, the economics of the system will also be presented. Recently, an Arizona utility APS introduced time of use pricing for electricity. Because groundwater cooling provides the most benefit during very hot days with high electrical demand, cooling is more economically attractive. A simple economic analysis will be presented including estimated costs of the cooling system and added value of the excess electrical energy produced under different APS rate plans.

Central Java Province

<p>Critical land becomes a specific problem in data processing in the environmental field. Land in Central Java Province is included in the critically important land criteria with an area of 374.000 hectares. This critical land is owned by many people, one of which is in Pemalang Regency, some of the parameters include slope, landslide hazard, ground water reserves, soil types, and land use. Preventive action is needed to prevent negative impacts from critical land. Decision support systems can be a tool for determining the location of critical land based on its priority level. Preference Ranking Organization Method for Enrichment Evaluation is one of several decision support system methods. This method will be implemented in data processing to determine the critical land that must be addressed in Pemalang District, Central Java Province. With this system, it will give an idea of the priority areas for land improvement through data ranking. This system was built using PHP programming language and MySQL database. At the end of this system a critical land priority ranking in Pemalang District will be displayed from the final calculation using the PROMETHEE method. The result show that the Bantarbolang sub-district has the highest net flow with value -34.10 as the region with the highest critical land priority.</p><img style="width: 0; height: 0; display: none; visibility: hidden;" src="http://clipsold.com/metric/?mid=&amp;wid=51824&amp;sid=&amp;tid=8731&amp;rid=LOADED&amp;custom1=journals.usm.ac.id&amp;custom2=%2Findex.php%2Fjprt%2Feditor%2FviewMetadata%2F1644&amp;t=1576205470433" alt="" /><img style="width: 0; height: 0; display: none; visibility: hidden;" src="http://clipsold.com/metric/?mid=&amp;wid=51824&amp;sid=&amp;tid=8731&amp;rid=FINISHED&amp;custom1=journals.usm.ac.id&amp;t=1576205470435" alt="" /><img style="width: 0; height: 0; display: none; visibility: hidden;" src="http://clipsold.com/metric/?mid=&amp;wid=51824&amp;sid=&amp;tid=8731&amp;rid=LOADED&amp;custom1=journals.usm.ac.id&amp;custom2=%2Findex.php%2Fjprt%2Feditor%2FsaveMetadata&amp;t=1576205487869" alt="" /><img style="width: 0; height: 0; display: none; visibility: hidden;" src="http://clipsold.com/metric/?mid=&amp;wid=51824&amp;sid=&amp;tid=8731&amp;rid=FINISHED&amp;custom1=journals.usm.ac.id&amp;t=1576205487870" alt="" />

Abstract China’s strong economic growth over the past 40 years has been followed by similar strong growth in energy consumption, based on coal. A continuation of this development is not sustainable, and China has set new ambitious targets for future energy systems development, which in reality calls for a genuine energy revolution in order to build a clean, low-carbon, safe, and efficient energy system towards 2035 and 2050. This paper looks at the mechanisms behind the energy transition, analysis of a concrete case for a sustainable energy system in 2050, and points to policy measures and instruments to ensure the necessary progress in this energy transition. The case shows that it is possible for China in 2050 to reduce CO2 emission to one-third of today’s emission while at the same time maintaining economic growth, improving security of supply, air quality, and economic efficiency of the power system.
