This chapter presents in a consolidated manner the step-by-step methodology to estimate the electrical energy potential of industrial wood residues considering the dependency of the efficiency of the power plants with their size. A function of the overall efficiency with power was obtained from a best curve fit of real data both taken from the literature and from Brazilian biomass-fired power plants. The methodology was applied to the determination of the electrical energy potential of wood industry residues in the State of Pará (data collected in 2004). Two cases were analyzed: one where a constant electrical efficiency of 25% was considered (independently of the amount of residues generated) and another where the proposed function of efficiency with power was used. Results show that in the State of Pará, the existent 675 sawmills generated 2.95 × 106 t in dry basis. When the dependency of efficiency with plant size is not considered, the electrical energy potential and average installed power (3140.4 GWh and 2 MWe) are overestimated in comparison to the herein proposed methodology (1868.8 GWh and 1 MWe). The present methodology, considering the efficiency as a function of the power, results in an average efficiency of 12.3% (lower than 25%).

Sawdust is often used as fuel for basic domestic needs like cooking, heating etc, with the application of the right technological procedure, the chemical energy in sawdust can be converted to electrical energy. sawdust is a usually a waste from timber processing industries and can pollute the environment if not properly disposed or utilized. Electricity can be generated from sawdust directly and sawdust can be processed into other products such as sawdust briquettes, pyrolysis oil, bioethanol and producer gas which can all be used to produce electricity using either a coal based thermal plant, oil based thermal plant and gas depending on the most suitable and efficient. As the calorific value of sawdust is dependent on the moisture content of the wood and the type of wood used, hence average calorific value of sawdust was used for this research work. In this study, the heat contents of sawdust and its various products were considered as fuels for divers power plants that is most suitable accordingly. This paper uses mathematical analysis to determine the amount of electrical energy produced from sawdust and it’s products. Sawdust briquettes was found to be the most efficient in terms of output power when a coal based thermal plant is utilized, the next being the utilization of a plain sawdust as fuel for a coal based thermal plant, the most optimal for the generation of electrical energy among the derivative of sawdust was pyrolysis oil being used as fuel in an oil based thermal plant.

The need for electrical energy in Indonesia continues to increase every year. In line with the increase in the electrification ratio to 100% in 2050, the demand for electrical energy is projected to reach 7 times, namely 1,611 TWh. To meet electricity needs, the government has created a 35 GW program, but one of the largest contributors to power generation fuel is coal with a share of 58% or around 50 GW which is estimated to be exhausted within the next 68 years. For this reason, innovations are needed in terms of fulfilling electrical energy by utilizing renewable energy potential, one of which is hydro energy, which is 45,379 MW from a total resource of 75,091 MW. Therefore, from this potential, innovations related to renewable energy have been created, namely the Hybrid Portable Underwater Turbine Hydro and Solar Energy hybrid power plant. This power plant uses an undersea current as a propulsion which is hybridized with solar power to increase the production of electrical energy. This power plant has the advantage that there is an Underwater turbine design that is resistant to underwater flow and a water flow direction to increase the work efficiency of the underwater turbine. From the test results, the portable Underwater turbine hydro produces 950 W in a day. Solar panels produce 65.6 Watts a day. The total hybrid that can be produced is 1.02 kW a day. In its implementation it can supply loads of up to 900 (VA) such as lamps, fans, TV, etc. This hybrid power plant can be a solution to help meet electricity needs in the area around Dusun Dongol, Sidoarjo through alternative electrical energy innovations.

Investments in energy sector are usually long term processes both in construction and exploitation phase, and therefore require many conditions to be satisfied, mostly from legislative and technical sector. While the legislative can change in accordance with economy activities in the country, technical data (on-site measurements) which are the main base for energy facility design, need to be reliable as much as possible. Wind energy has a significant global potential which exceeds the world?s electrical energy consumptions. This paper presents the estimation of wind energy potentials in Montenegro, based on all previous available studies in this field. The wind energy potential in Montenegro is based on a combination of 3-D numerical simulations of wind fields on the entire territory, and comprehensive on-site measurements. The preliminary studies show that there is a potential of areas with high and mean values of a capacity factor about 400 MW, and annual production of 900 GWh of electric energy. The share of wind parks in the total installed power in Montenegro is planned to be about 8%, while an adequate ratio of wind parks in an annual production from renewable sources (large hydro power plants are included here) is estimated to be 11.4%. The paper presents the current state of art in the field of building of wind parks in Montenegro. A particular attention was paid to the legislation framework and strategic documents in the energy area in Montenegro.

Nowadays, Indonesian government is focusing on build up infrastructures, especially power plant infrastructures to fulfil electrical energy needs. One of the power plants that will be built up is Waai power plant which located on Waai village, Maluku Province. Waai power plant had been postponed since 2014. In order to build this power plant, the advisability of the building needed to be checked from its verticality level. This level was determined by Terrestrial Laser Scanner (TLS). The TLS’s point clouds were registered using two methods, there are target to target and cloud to cloud methods. There are 65 beams on the power plant boiler building, but only 31 beams that used as the samples to assign the verticality of the boiler construction. The verticality level was set on the X-axis, Y-axis, and the resultant of the X and Y axis by using Pythagoras theorem after the bottom and top coordinates from each beam was determined. The Queensland Building and Construction Admission Standards and Tolerances Guide 2016 was used as tolerance of verticality level. The result of the verticality calculation presented on the X-axis consisted from -0ᵒ 1’ 26,678” to 0ᵒ 4’ 11,778” with the average was 0ᵒ 1’ 40,820” and major direction pointed the positive axis. On the Y-axis, the average was -0ᵒ 0’ 45,772” with -0ᵒ 3’ 33,345” as minimum and 0ᵒ 1’ 25,319” as the maximum and the major direction went to the negative axis. The verticality on the resultant of X and Y axis was from 0ᵒ 0’ 45,225” until 0ᵒ 4’ 15,674” with the average was 0ᵒ 2’ 27,057” and the direction was to the southeast. After the verticality number was compared with the tolerance, the verticality level was smaller than the standard on each beam. From the result, we can conclude that the boiler building on the Waai power plant can be categorized safe to reconstruct.
