Hydropower generated systems are one of the common source to generate energy. The renewable energy generation system is designed to use the water flow from an overhead tank during normal consumption of water for domestic use. The system produces electricity from the potential energy of water flow through water pipelines by changing the kinetic energy of water into electricity. The electrical energy is stored in batteries for domestic purposes like lighting and other electrical applications. The system has two turbines coupled with generator, placed at the inlet and outlet pipe of the water tank. The status of water level is detected with the help of float sensor. The motor performs automatically according to the level of water. The generated power is informed to the user and then stored in a battery storage unit. When the energy saved within the battery is sufficient an inverter is switched ON for domestic use. During the normal time of working load receives power from the ordinary commercial line. The system is simulated with Proteus software and analysed.

With the rising demand for energy, the forest-based circular bioeconomy is gaining recognition as a strategy for sustainable production and consumption of forest resources. However, the forest-based bioeconomy remains underexplored from the perspective of deadwood conservation in public forests. While conducting a literature review and examining the case of Kenya, this study fills a gap in the literature to provide policy suggestions for sustainable forest resource utilization. The results from global literature indicate that deadwood performs essential social, economic, and environmental functions in the circular bioeconomy and sustainable development. Similarly, in Kenya, deadwood resources provide many socially beneficial bioproducts and services. However, the absence of scientific research and detailed guidelines for deadwood conservation may lead to the distortion of the ecological balance in public forests because of the legally sanctioned removal of deadwood, particularly firewood. Moreover, if the status quo remains, with approximately 70% of the growing population consuming deadwood for domestic use and the demand increasing, as shown by the current wood deficit in the country, there will be a major dilemma concerning whether to conserve deadwood for biodiversity or energy. Therefore, averting crisis and providing maximum deadwood value to society requires guidelines and comprehensive research in addition to a cultural and behavioral shift in energy consumption in a manner that embraces the forest-based circular bioeconomy of deadwood.

The supply of electrical energy in Tarakan City, North Kalimantan, still relies on diesel power which uses a limited number of petroleum energy sources. There is a need for research related to renewable energy sources that have the potential to become alternative energy for the people of Tarakan City. Water is an energy source that has great potential to generate electricity. The energy source that should be taken into account is micro-hydro which can be used as a Micro-hydro Power Plant (PLTMH). A survey of micro-hydro sources in Tarakan City, precisely in the Karungan area, East Mamburungan Village, has been carried out with the direct measurement method of water discharge and the relationship with the power generated. The result shows the water source has a discharge 0.00034 m3/ s, the water velocity of 0.035 m/s and generates power only up to 1.1 watts. Based on the power obtained, the water source in this place cannot be used as a source of micro-hydro energy, but has the potential as a source of pico-hydro energy.

The Future

The goal of power sector in Nigeria is to efficiently and reliably transmit electrical power to all parts of the country which are made up of thirty-six states of the federation and the federal capital territory. The constituents of electrical power system are the generation, transmission, distribution and the utilization of electrical energy. There is gross power imbalance between the generation and the required power demand which has culminated into a defective economy in the last three decades. This paper therefore examines the power imbalance between the generation and power demand by the consumers and therefore stresses the need to harness the opportunity of renewable energy generation close to the gap between the power generation and power demand. This will help in transmitting and distributing efficient, effective, reliable power to consumers and improve both human and capital development. The availability of renewable energy sources such as sun, wind and small hydro power will be explored for the future of power generation in the country to fill in the gap between power generation and demand in Nigeria

Voltage and frequency stability of a micro hydro power plant requires a simple, reliable and efficient control system. This study aims to design a control system using planetary gear which is known to provide fast speed adjustments to respond to the changing rate of water flow. In this study the system design will be created using matlab simulink. The system will then be simulated with various turbine rotation conditions to see the reliability and stability of the frequency and voltage produced by the permanent magnet generator used in micro hydro power plant. The results obtained are the control system seems can stabilize the generator rotor rotation so that the resulting voltage frequency remains constant even though the input load and water flow rate are dynamic. From the simulation results it is also found that the efficiency of the control system is directly proportional to the difference in mechanical input and electric power output of the system.

H2o2 System

Sulfolane is an emerging contaminant in the groundwater and soil nearby gas plants, which has attracted much attention from many researchers and regulatory agencies in the past ten years. In this paper, a field pilot-scale ultraviolet (UV)/hydrogen peroxide (H2O2) system was investigated for treating sulfolane contaminated groundwater. Different groundwater, as well as different operational parameters such as influent sulfolane concentration, H2O2 dosage, and water flow rates, were studied. The results showed that a pilot-scale UV/H2O2 system can successfully treat sulfolane contaminated groundwater in the field, although the presence of iron and other groundwater limited the process efficiency. The lowest electrical energy per order of reduction for treating sulfolane in groundwater by using the pilot-scale UV/H2O2 system was 1.4 kWh m−3 order−1. The investigated sulfolane initial concentrations and the water flow rates did not impact the sulfolane degradation. The enhancement of sulfolane degradation in an open reservoir by adding ozone was not observed in this study. Furthermore, an operational cost model was formulated to optimize the dosage of H2O2, and a stepwise procedure was developed to determine the power necessary of the UV unit.

Save Energy

In cold climate regions, the energy associated with indoor heating constitutes a large portion of energy consumption. Increasing energy utilization efficiency is critically important for both economic and environmental reasons. Directly converting electrical energy to thermal energy using joule heating construction elements can save energy and investment to the water pipelines which have been extensively used for indoor heating in China. The fired brick has been extensively used to make pavements, walls and other masonry. Taking advantage of the high dispersion quality of graphene oxide (GO) in water, as well as the firing process used to make fired bricks, graphene nanocomposite bricks with excellent electrical properties and improved mechanical performance were prepared in China. The compressive strength of the bricks showed a substantial increase from 3.15 MPa to 7.21 MPa when GO concentration was 0.1 wt.%. Through applying 5 volts of electrical field within 5 minutes, the nanocomposites can be heated from room temperature to 60 °C, 110 °C and 160 °C for the nanocomposite bricks with graphene concentration of 3 wt.%, 4 wt.% and 5 wt.%, respectively, due to the extremely low percolation threshold (~0.5 wt.%) and high conductivity (10 Ω·cm at 1 wt.%). The sheets were connected more tightly when the GO content was increased. The thermal efficiency can reach up to 88% based on the applied voltage, measured resistance and temperature rise curves.
