With the rapid development of Chinese economic, environmental pollution, energy shortages and other issues become increasingly prominent. Relying solely on the power construction is difficult to meet the country's rapidly increasing demand for electricity. Energy conservation, rational and efficient use of energy is the effective initiatives to protect the environment and ease the energy shortage. Efficiency Power Plant (EPP) can improve the energy utilization efficiency of the whole society. It is the most new energy-saving mode, many issues need to coordinate and handle during its implementation. Benefit sharing is a key prerequisite for enterprise to implement the EPP. In this paper, we integrate all aspects of EPP’s risk factors during its implementation to build a benefit sharing model of Efficiency Power Plant. And prove the feasibility and accuracy.

Discovery Algorithms

With the quick development of Internet of Things (IoT), one of its important supporting technologies, i.e., wireless sensor networks (WSNs), gets much more attention. Neighbor discovery is an indispensable procedure in WSNs. The existing deterministic neighbor discovery algorithms in WSNs ensure that successful discovery can be obtained within a given period of time, but the average discovery delay is long. It is difficult to meet the need for rapid discovery in mobile low duty cycle environments. In addition, with the rapid development of IoT, the node densities of many WSNs greatly increase. In such scenarios, existing neighbor discovery methods fail to satisfy the requirement in terms of discovery latency under the condition of the same energy consumption. This paper proposes a group-based fast neighbor discovery algorithm (GBFA) to address the issues. By carrying neighbor information in beacon packet, the node knows in advance some potential neighbors. It selects more energy efficient potential neighbors and proactively makes nodes wake up to verify whether these potential neighbors are true neighbors, thereby speeding up neighbor discovery, improving energy utilization efficiency and decreasing network communication load. The evaluation results indicate that, compared with other methods, GBFA decreases the average discovery latency up to 10 . 58 % at the same energy budget.

Increasing Demand

Agricultural greenhouses are commonly built around cities to supply residents with agricultural products or green plants. With an increasing demand for plants’ growing environment, the temperature and illumination inside the greenhouses are counted especially during cold winter. This paper proposes a new construction idea of an energy-saving agricultural greenhouse, by which a solar energy collector is added onto the agricultural greenhouse to improve the energy utilization efficiency. Besides, the solar collector does not occupy extra land resource and merely influence the illumination inside the greenhouse. The design and modeling of solar system are introduced in accordance with the actual parameters of agricultural greenhouse. Then the characteristics of energy collection and inner house’s illumination are elaborated by simulation. It shows that when the inclination incident angle of the sunlight ranges from -38° to 38°, the receiving efficiency of ray in receiver is more than 80%. This implies that the system can work about 5 hours in heat collection. The light environment and the thermal environment are both important. When scattered and direct light are set 40% and 60% of daylight, respectively, the illumination of ground is up to 8.38×105 Lux. The minimum illumination is not less than 4.22×105 Lux. In addition, the illumination of rear wall ranges from 3.05×105 Lux to 7.62×105 Lux. Thus, the light environment in the greenhouse is not influenced and all the indoor activities could be maintained. Finally, local meteorological data are combined with simulated solar collection results to evaluate the economy. It shows that the system could provide about 1887.8 MJ/m2 in six cold months, which approximately equals to 6153.9$ per year.

The energy performance certificate for buildings shall include reference values such as currant legal standards and benchmarks in order to make it possible for consumers to compare and assess the energy performance of the building. The certificate shall be accompanied by recommendations for cost-effective improvement of the energy performance…” The following steps shall be required for the energy certification: 1.

To solve the problem of rapid development of domestic water tourism and water pollution in scenic waters, windsurfing technology and solar photovoltaic technology are applied to small and medium-sized sightseeing cruise ships. While optimizing the hull design and component coordination, the application of automatic control technology further improves the utilization efficiency of wind and light energy, and achieves the adaptation of the sail angle of attack and the efficient coupling of the two energies. The ship mainly uses the natural resources of solar energy and wind energy. It will not burn fossil fuels during the ship’s travel, thus reducing the emission of toxic and harmful substances, which has positive significance for environmental protection. In short, the solar wind-assisted power generation ship studied in this project has remarkable features such as zero emission, high degree of intelligence, significant wind-assisted effect, high efficiency of light energy utilization, and low hull space occupation. Compared with the ordinary lake area cruise ship, the energy-saving and emission reduction effect of the power generation ship is very obvious[1].

Increasing Demand

Energy consumption in Indonesia is increasing every year, the fulfillment of the energy needed must be overcome. Energy is something that is really needed by anyone, from humans or animals to be able to do something or work. This energy is also abstract, its existence can be felt, but it is difficult to prove. Electricity needs of the community today are a basic need. Electricity usage is almost 24 hours nonstop. To cope with the increasing demand for electricity, it is necessary to utilize natural resources that can be used as new energy resources. The floating hydro power plant simulator is a hydroelectric power plant that utilizes the flow of water from a pump to drive a waterwheel, a device designed to make it easier for students to learn basic electrical engineering and fluid mechanics. The purpose of this design is to design and build a floating hydro power plant and test the tool. The design method used the VDI 2222 method approach, which includes planning, conceptualizing, designing, finishing. The results of the design were according to the method used, namely in the form of a waterwheel simulator design for power plants. The estimated production process time for the manufacture of a floating hydro simulator for cutting 3.9 hours; process of gurdi 3.08 hours; lathe process 1.3 hours; 1.58 hours assembly process; finishing process 2.75 hours = 1.2 days (1 day = 8 hours). The total cost of making the machine was Rp. 2.605,740.00. The driven pulley test results in 65.4 rpm and the driven pulley produced 304 rpm and the output was 12.3 volts.

Natural gas is a major type of distributed energy. In the current power system structure aging, environmental protection, energy utilization efficiency bottleneck and the user requirements for power quality standards increased the world's demand for new energy. So the development of distributed energy has become the common choice of the countries around the world and become the new direction of global energy development. Compared with the traditional energy supply distributed energy has many advantages, but because of its grid producing, feed-in tariffs, subsidies rules is not detailed, unclear development ideas led to the development of distributed energy slowly. How to develop effective policies to promote the development of natural gas distributed energy become the hot spot of attention.
