The document summarizes an investigation into an oil spill that occurred during the handling of an Intermediate Bulk Container (IBC) at an environmentally sensitive construction site in Australia. The root cause was determined to be an inadequate inspection process, as the inspection failed to identify a deformity in the metal base plate of the IBC that subsequently caught on the telehandler tynes during lifting and punctured the container. Contributing factors included the IBC design not anticipating such conditions, and the lack of a spotter to identify the deformity. Engineering and process controls were implemented to prevent future spills from similar piercings during lifting.
Energy Demand Analysis of Telecom Towers of Nepal with Strategic Scenario Dev...IJRES Journal
Telecom towers, technically known as BTS (Base Transceiver Stations) are the most energy intensive part of cellular network architecture and contribute up to 60 to 80% of total cellular power consumption and varies in response to the real traffic demand throughout the day and night. But, thelack of grid availability highlightsa potential barrier to telecom industry growth in Nepal. Nepal has approximately 5,222 telecom towers of which about 22% do operate on diesel generators (DGs) while the remaining by grid electricity with some shares of renewable energy technologies (RETs: solar and/or wind). Despite the large carbon imprint, the uncertainty in power availability has compelled telecom operators to use DGs to ensure continuous supply of power for the better network availability, which translates huge operating costs along with adverse environmental impact. So, it becomes an imperative solution for telecom operators to evaluate all alternatives in order to increase network reliability with reduced energy cost. This study report intentionally focus on current energy consumptionof such telecom towers and forecast thefuture energydemand with reference to growing subscriber trend up to 2025 using LEAP (Long Range Energy Alternative Planning System)withBusiness As Usual (BAU) scenario. A clean energy technology (CET) scenario with possible RET options is also developed and compared with base case scenario through some policy mechanics on behalf of environmental benefits and sustainable cellular communication. Furthermore, this study concludes a potential energy cum cost saving with RET adoption with basic cost economics analysis.

The utilization of conventional sources of energy releases harmful pollutants to the environment causing global warming and acid rain. For that reason, it becomes necessary to use a non-depletable, sustainable and eco-friendly renewable energy as a mean of producing electricity. Malaysia is tropical country rich in resources beneficial in electricity generation as it is in equatorial region therefore it has an abundance of solar irradiance of average annually. In addition, Malaysia’s demand in electricity is increasing to 124,677 GWh by 2020. Therefore, the electricity generation from renewable sources in Malaysia is anticipated to grow in the future alongside the government endorsement due to its clean, eco-friendly and free source of energy which can highly reduce the dependency on oil and gas that emits harmful pollutants to the environment. This paper gives a comprehensive review on the renewable projects and researches in Malaysia, challenges that affect popularity of renewable energy in Malaysia and available and successful renewable energy system in Malaysia.
Model for Evaluating CO2 Emissions and the Projection of the Transport Sector IJECEIAES
This document presents a system dynamics model to analyze carbon emissions from Bogota's transport sector under different policy scenarios from 2005 to 2050. The model considers population growth, private and public vehicle fleet growth, passenger trips, and resulting CO2 emissions. Four scenarios combine urban development and environmental policies. Scenario 1, with balanced development and environmental policies, shows the lowest emissions growth. Scenario 2, focused on development without environmental policies, shows the highest emissions and fleet growth. Implementing balanced and coordinated urban and environmental policies can effectively reduce transport sector emissions.

Transition of the Electricity System from conventional
generation to a dispersed and/or RES system
Currently electricity systems are facing a transition caused
by several different reasons, e.g. a growing trend in renewable
generation development which most of them have intermittent
nature, a change of transmission systems from pure AC to hybrid
AC/DC-Systems, the development of special protection schemes,
overhead lines with partial undergrounding and others. This
paper focuses on the transition of the electricity system caused
by the ongoing penetration of RES.
Performance analysis based on probabilistic modelling of Quaid-e-Azam Solar P...Power System Operation
The solar photovoltaic (PV) technology has gained global importance to overcome the global warming and meet
future energy needs. The performance of a solar PV plant depends on many factors such as solar irradiance,
weather conditions, various types of energy losses and system degradation over time. Although the deterministic
models nicely predict the PV performance at a single instant in time, however, they fail to account for the uncertainty
and randomness in the input parameters. Probabilistic models, in contrast, are more useful to predict
the system performance over a time span under real conditions. In this study, a probabilistic model has been
developed for the performance analysis of a recently commissioned 100 MW power plant at Bahawalpur,
Pakistan. The model is based on Monte-Carlo simulation method and uses the probable range of input data from
the site of the power plant. The performance of the power plant is presented in terms of monthly and seasonal
electricity generation. The associated energy losses are discussed in detailed. Furthermore, a comprehensive cost
analysis of the power plant has been provided. According to results from the model, the power produced in the
first year of operation of the plant is 136,700 MWh and the projected cumulative energy produced during a plant
lifetime of 25 years is 3,108,450 MWh. The levelized cost of energy (LCOE) estimated by the model is 0.0795
$/kWh, which is quite reasonable in comparison to the average 0.1 $/kWh cost of electricity to a domestic
customer in Pakistan.

Putting hydropower and renewables in contextCPWF Mekong
This document summarizes a project assessing the potential role of renewables in power supply in the Mekong region. It finds that renewables have significant technical potential, including over 90 GW from solar, wind, geothermal, small hydro and biomass. However, renewables face barriers to wider deployment. Hydropower currently plays a major role in centralized grid systems, while renewables are smaller-scale and connected to distribution networks. High renewable penetration will require technologies like gas or hydropower that can respond quickly to output variations. While not direct substitutes, hydropower and renewables could complement each other, with hydropower helping to integrate variable renewables. Realizing their synergies would require changes to institutional

Evaluation of the photovoltaic generation potential and real time analysis of...Arq Taciana Muller
This document summarizes a study that evaluated the photovoltaic generation potential and real-time analysis of a photovoltaic panel installed on a building in southern Brazil. The study found that the 16.5 m2 photovoltaic panel produced an average of 11.0 kWh per day and had a module efficiency of around 12.6%. Solar radiation and daylight data from 2007-2012 were used to analyze the solar potential and compare to the panel's power generation. The panel was installed at an angle of 24 degrees, which modeling software had indicated would provide the most uniform radiation throughout the year for that location.
Evaluating expected and comparing with observed risks on a large-scale solar ...Turlough Guerin GAICD FGIA
The overwhelming benefits of building solar power plants instead of fossil fuel powered sites for new generation
capacity outweigh the less significant risks, some of which are identified in this study on the construction stage
of a utility-scale solar energy (USSE) project. This project confirmed and clarified the nature of environmental
and community risks to be expected on Australian construction sites. Expected risks from desk top studies and
related planning requirements captured the majority of those risks actually experienced in the field during the
construction phase. The large number of approval conditions (set by the relevant regulatory authorities; state
and local) for the construction stage of the project, are arguably excessive compared with the risk profile of the
project, and the overall positive benefits to the environment, economy and local community. The environmental
and community risks of greatest concern (including dust control, optimising vegetation growth under the
panels, waste management, a lack of common understanding of expectations for local job opportunities), while
planned and eventually managed, could have been more efficiently addressed by further upfront investigations,
and questioning and enhancing the governance processes by the engineering procurement construction (EPC)
entity (or constructor). For example, managing the end-of-life packaging materials (EOLPMs) was a specific
unexpected risk on the project during the construction stage, which can be overcome on future remote location
projects by enhancing the design and execution of project-level contracts and securing partners such as resource
recovery companies or other end users (of EOLPMs) at the earlier, planning stage. Recommendations for
regulators include to reduce approval constraints on new low-emissions electricity developments, particularly at
the state and local government level. These should be considerably less onerous than building new fossil fuel
electricity generation infrastructure. A sharper focus on regulatory red tape reduction will enhance USSE project
adoption.

It also analyzes the system's net present value, internal rate of return, investment payback period, and energy payback time. The document concludes that while upfront costs are high, solar PV could ensure cleaner energy and reduce greenhouse
This document summarizes a case study on the operational performance of a 1 megawatt rooftop solar photovoltaic plant in India. The study monitored the plant's performance over 12 months and compared the real energy outputs to simulations from three tools: PVGIS, PV Watts, and PV Syst. On average, PVGIS predictions were most accurate with a 5.33% mean bias error, followed by PV Watts at 12.33% and PV Syst at 30.64% error compared to actual outputs. While simulations provided estimated performance, real-world monitoring showed deviations from predictions and is important for assessing solar projects.
The building integrated photovoltaic (BIPV) system have recently drawn interest and have demonstrated high potential to assist building owners supply both thermal and electrical loads. In this paper, the BIPV technology has been reviewed, in terms of its performance, efficiency and power generation capacity. Specifically, the applications of the BIPV in tropical climate regions have been discussed, together with its prospects and challenges. For these schemes to be implemented in a tropical climatic region, the following issues must be considered: 1) Certain studies must be done relating to electrical load demand, predicted PV output, location of the buildings and its integration and constraints associated with roof design; 2) For the highest energy production from solar PV, the solar collectors need to be with the right tilt depending on the location; 3) Design criteria such as safety, efficiency, durability, flexibility and constructive issues need to be considered; 4) The government of such countries must train electricians and carpenters on PV installations; 5) The BIPV roofing must perform same function as normal roofing materials, such as noise protection, water tightness, insulation and climate protection, and 6) As practiced around the world, these countries must establish design standards for the BIPV.

This document discusses renewable energy resources applied to zero energy houses and buildings. It provides examples of zero energy building projects in various countries and communities that have achieved high percentages of energy from renewable sources. It also analyzes the costs and payback times of different sized solar and wind power projects for residential and commercial buildings. While the upfront costs can be substantial, the analysis shows most projects achieve payback within 6-10 years and are cost effective over the long term as they provide free energy for 80% or more of the project lifetime. The document concludes zero energy buildings and greater use of renewable resources can help make the world more sustainable and reduce pollution from fossil fuel use.
This document summarizes a study that examines factors influencing the adoption of photovoltaic (PV) systems by households in rural areas of Poland. The study surveyed 521 participants without PV systems in rural Poland. It used structural equation modeling to analyze the relationships between environmental concerns, consumer innovativeness, subjective knowledge of PV, perceived economic benefits and risks of PV, perceived value of PV, and intention to purchase a PV system. The main findings were that consumer innovativeness had the strongest positive impact on purchase intention, while perceived value also positively impacted intention. Perceived economic benefits and subjective PV knowledge indirectly affected intention through perceived value. Surprisingly, environmental concerns negatively impacted purchase intention.

BUILDING AN EFFICIENT SOLAR CHARGER AND COMPARING ITS CHARGING SPEEDS WITH A ...SukhpreetSingh164
Abstract of the Research Paper
Energy sources using exhaustible energy at its input are being discouraged because they cause significant damage to the environment and human beings. Solar energy is considered one among the clean and green energy sources because it takes sunlight as its input which is a renewable energy source. There are many places in the world where electricity is not constant or not available. There are also cases where solar energy is neglected by people simply because of a lack of knowledge of its efficiency, and it is basically considered non-efficient. The purpose of this research is to build a solar charger, test its workability, and compare its efficiency with a regular wall charger to provide information for it to be used by both rural and urban people. Both quantitative and qualitative approaches were used appropriately, and most efficient circuit parts and appropriate testers were used in this research study to achieve the objectives. It was found that the solar charger was almost as efficient as a regular wall charger. There were some factors which decrease the efficiency of the solar charger which may be analyzed by future researchers on this concept. In conclusion, after being found that a solar charger is as efficient as a regular wall charger, its use must be encouraged by both rural and urban people.

This document summarizes the status of building integrated photovoltaic (BIPV) applications in Malaysia. It discusses that between 1998-2002, Malaysia successfully completed several pilot BIPV projects totaling over 400kWp installed across various buildings. Key lessons learned included addressing issues like roof leakage and lightning protection that are prevalent in the tropical climate. While BIPV system costs in Malaysia have decreased significantly, costs remain relatively high compared to other countries due to components still being imported and lack of local market. The government is now working to further develop BIPV through new programs and a national steering committee on renewable technologies.
Development of Smart Grid Interoperability for Energy Efficiency Systemsijtsrd
The power grid is at present undergoing a chronological transform of state from the conventional structure where a utility owns the generation, transmission and distribution services into an integrated smart grid in a monopolistic market which introduce consumers as active players in managing and controlling the power. This report provides development of smart grid interoperability for energy efficiency. A systematic approach for developing smart grid interoperability tests was adopted by analyzing two houses, two industries and two institutions while looking at the analysis of their active power. This analysis of active power gives the exact idea to know the range of maximum permissible loads that can be connected to their relevant bus bars. This project presents the change in the value of Active Power with varying load angle in context with small signal analysis using wind, solar and generator grid . The result obtained showed that, consumers can then choose the cheapest energy to be consumed at convenience with a major focus on the institutional results which showed that, with either solar or wind they can have constant supply for a period between 8am to 10pm on daily basis, since their major operations are done in the day.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
