Important Basis

Energy consumption in the world is mainly dependent on fossil energy, and oil is one of the main energy sources. Accurate prediction of oil consumption can provide an important basis for national energy security, which can provide reference and early warning for the implementation of the environmental strategy developed by the government. According to the nonlinearity of the energy system, this paper uses the principle of the grey nonlinear prediction model NGBM(1,1) to improve the background value of the model, and by the simulated annealing algorithm, we put forward the optimized grey nonlinear model ONGBM(1,1). At the same time, the model is applied to the oil consumption of China, Chile, Mexico, and Japan. Based on the validity analysis of the existing data of the four countries, the model ONGBM(1,1) is basically superior to the other six grey forecast models. Finally, ONGBM(1,1) is used to predict the oil consumption of the four countries in the next five years, which can provide effective information for energy economic policy.

Oil And Gas Sector

Energy sovereignty in Indonesia is experiencing problems with a decline in national energy security. Indonesia's energy system is currently facing serious challenges. The imbalance in the condition of energy supplies with national energy needs, especially the oil and gas sector and efforts to fulfill national energy needs in a sustainable manner are the main problems of this nation in the energy sector. It is absolutely necessary to have strategic efforts in the field of creating new and renewable energy. Although the government has issued various policies to catch up, but to realize national energy security, it is necessary to urgently regulate the development of renewable energy as a form of supporting national energy security. As for the formulation of the problems raised in this study are: support national energy security in Indonesia? 2) what is the urgency of regulating the development of renewable energy as a form of supporting national energy security? This research will use normative juridical research and supported by empirical juridical research so that it will be able to see the conditions of developing renewable energy as a form of supporting national energy security in Indonesia. To realize this, it is necessary to urgently regulate the development of renewable energy as a form of supporting national energy security.

This article reviews energy consumption in the Kyrgyz Republic economy, environmental indicators and strategies to further develop the national fuel and energy system to ensure energy efficiency and energy saving. An existing situation in energy efficiency of buildings in the country is described. Secondary legislation and by-laws approved by the Government of the Kyrgyz Republic as well as several technical standards, norms, methods and guidelines approved by the order of the State Construction Agency of the Kyrgyz Republic are presented. Applying modern insulating materials are suggested as possible solutions to increase energy efficiency and energy saving. The advantages of EPS-beton in comparison with other thermal insulation materials are discussed and foreign experience of use of EPS-beton products in increasing energy efficiency of buildings is presented.

Do So

The present paper is an attempt to get total minimum of trigonometric Functions by Simulated Annealing. To do so the researchers ran Simulated Annealing. Sample trigonometric functions and showed the results through Matlab software. According the Simulated Annealing Solves the problem of getting stuck in a local Maxterm and one can always get the best result through the Algorithm.
