The need for new plants is needed to balance the demand for high electricity. To anticipate this, it is necessary to accelerate the achievement of the level of utilization of new and renewable energy (EBT) in the energy mix for electricity supply by encouraging the use of energy from water, biomass, solar, wind to electricity. The Biomass Power Plant (PLTBm) is one of the environmentally friendly alternative power plants that produce electricity and heat by burning biomass in boilers in this case from wood waste from furniture and old rubber trees. The Interconnection System will be implemented in this PLTBm, where interconnection with the existing 20 kV system will be carried out. Research carried out includes power flow, voltage drop, losses, and short circuit. By conducting this study, it can be seen the profile of the overall system operation before and after this interconnection. The simulation results show that the PLTBm connected to the nearest feeder point from the generator is the best choice in terms of making the system voltage better between 19.1 kV and 20.17 kV. Power losses range from 439 kW and 5005.4 Kvar as well as short circuit currents, namely 13.73 KA.

Additional Reduction

In the last 20 years, automotive engineers in the United States have made considerable progress in emission control. Hydrocarbons, carbon monoxide and nitrogen oxides have been reduced substantially. Despite this, new legislation passed in 1970 requires an additional reduction below the present levels by 1975–1976, and this lecture discusses this new engineering challenge. General Motors’ latest progress with alternative power plants and their relative feasibility in both the near and more distant future is discussed.

The article summarizes the experience of risk neutralization arising due to the power generation from the alternative sources solar, wind, hydraulic power engineering on the basis of ebbs and flows, the use of biomass power plants, etc. At the same time, the tool for blitz diagnostics of risks of the alternative power engineering is proposed in order to substantiate the economic feasibility of investments. The results of the risk assessment application of alternative power engineering reduce the level of information uncertainty relating to the transition to new energy sources or diversification of energy supply.

Problem. There was a need to expand the well-known concept of vehicle operational properties – fuel efficiency arose in connection with the advent of new alternative power plants (electric motors, flywheel engines, hybrid power plants, etc.), which requires the inclusion of not only the thermal energy of the fuel, but also other types of energy (electrical and mechanical). In the paper the research of choice and justification of the vehicle energy efficiency indicators by assessing the energy costs of the engine for its movement was made. The analysis of the relationship between energy characteristics of dynamics and vehicle efficiency was made. Goal. The aim of the study is to analyze methods for assessing the vehicle energy efficiency. To achieve this goal, it is necessary to determine indicators that will allow a comparative analysis of energy efficiency indicators of various vehicles. Methodology. The approaches taken in the work to solve this goal are based on substantiating the indicators of the energy efficiency of the car by assessing the energy consumption of the engine for its movement. Results. In our opinion, in projecting and evaluating the dynamic properties of vehicles, it is rational to use the energy indicators of the vehicle, for which it is necessary to develop appropriate assessment criteria. Analysis of the results of indicators calculation and, in table 1, has shown that the indicator in comparison with has less dispersion. Originality. The obtained results of the influence of the parameters of vehicles on the level of their energy load shows that the indicator has less dispersion than. In addition, the value does not correlate with the year of manufacture of the vehicle, which allows the use of this indicator at the design stage of vehicles. It is only necessary to set the rational normative value of this indicator. Practical value. The results obtained can be recommended to specialists for use in the design, production, certification and operation of automotive vehicles, vehicle energy efficiency, combined power plant.

The renewable energy has a very important role in meeting energy needs. This is because the use of fuel for conventional power plants in the long term will deplete the dwindling resources of oil, gas and coal and can also cause environmental pollution. Solar panels based on 2N3055 transistors and Thermoelectric Cooler (TEC) are the basic materials for designing alternative power plants. In the manufacturing process, this solar panel utilizes electronic components that are capable of generating electrical energy (emf), so that it can be used as an appropriate technology to produce a solar panel that utilizes solar energy in the form of heat and solar radiation. The use of transistors 2N3055 and TEC proved to be more efficient in generating electrical energy, there was no significant decrease in voltage and current even though the weather was suddenly cloudy. The average voltage and current generated in this solar panel are 24.58 VDC and 2.72 Ampere DC.

Alternative Power

The erratic power supply has been a growing cause for concern in developing countries. It becomes more challenging to supply adequate energy in countries with a high population due to the increased demand and this has led to load shedding and spreading in Nigeria. Also, emissions from power plants, impacts of hydroelectric development, and risks associated with nuclear energy use have been targets for political action due to the recent pursuit of sustainability development. Also, evidence of depletion of the protective ozone layer and its impact on the environment have urged the need for rapid development of alternative power generation method void of causing adverse environmental impact. This paper, therefore, discusses the design and evaluation of a self-starting fuel less power generator using DC motor as the prime mover to generate electrical energy from an alternator. The alternator armature shaft was coupled directly with DC motor powered by a rechargeable battery. The DC motor rotates the armature of the alternator in the field coil at high speed when activated from the starting switch, which results in alternating current output voltages of 220V.
