Abstract Although crystalline silicon PV technology has been in use for more than 30 years, PV has remained a "cottage industry" until the recent expansion. This paper provides an introduction to the issues of reliability in the photovoltaic (PV) field, and the work the Department of Energy's Solar Energy Technologies Program is focused on to address these issues. In particular, the works of the Reliability Programs at both Sandia National Laboratories and the National Renewable Energy Laboratory are reviewed with several examples of results included and sited. Expanding reliability assessment and failure analysis techniques for components and systems can enhance the reliability of PV systems, which is necessary for large-scale deployment of PV as a power generation source.

The Impact

AbstractAs renewable energy supply chains have grown increasingly globalized, national clean energy transitions have become highly influenced by international dynamics. However, these dynamics are themselves collectively shaped by domestic policy that drives the deployment of renewables. While spatial spillovers of domestic renewable energy policies have been studied on an aggregate level regarding policy diffusion or the flows of technology across countries, implications on an actor-level have been largely neglected. This article addresses this gap by analyzing global patterns of market openings for wind, solar PV, and biomass, focusing on the role of private project developers in developing countries. We use a mixed method design, based on a newly merged dataset encompassing eighty countries, and on interviews with pioneering project developers. Results highlight how patterns in market openings are shaped considerably by technology characteristics. Further, empirical results show international private developers are a key first mover in many developing countries. We explore drivers for this internationalization trend, including the impact of international developers' home country policies and the accumulation of tacit knowledge from home country markets for market openings abroad. Finally, we discuss implications for industrial policy and argue for further research on global spillovers of national policies on the actor-level.

One of the most encouraging sorts of renewable energy is ocean wave energy. In spite of a large number of investigations in this field during the last decade, wave energy technologies are recognised as neither mature nor broadly commercialised compared to other renewable energy technologies. In this paper, we develop and optimise Power Take-off (PTO) configurations of a well-known wave energy converter (WEC) called a point absorber. This WEC is a fully submerged buoy with three tethers, which was proposed and developed by Carnegie Clean Energy Company in Australia. Optimising the WEC’s PTO parameters is a challenging engineering problem due to the high dimensionality and complexity of the search space. This research compares the performance of five state-of-the-art metaheuristics (including Covariance Matrix Adaptation Evolution Strategy, Gray Wolf optimiser, Harris Hawks optimisation, and Grasshopper Optimisation Algorithm) based on the real wave scenario in Sydney sea state. The experimental achievements show that the Multiverse optimisation (MVO) algorithm performs better than the other metaheuristics applied in this work.

The climate change, the global warming, the population growth and the continuous demand on energy and electricity in specific made renewable energy one of the most appropriate and fitting to answer all these changes of our environment. However, the vested interested groups belonging to the fossil fuel cartel continue working tirelessly to discourage the use of renewable energy and renewable energy solutions in the world. Despite the recusant efforts of the Oil Cartel, renewable energy use has grown much faster than anyone anticipated. This paper: defines green and renewable energy; highlights its benefits; and illustrates that clean energy technologies are prepared for accelerated and widespread expansion in the global power sector. The paper critically examines the recusant efforts of the Oil Cartel undermining green renewable energy sector by bankrolling the production of unconventional oil and gas; and demonstrates that over-reliance on fossil fuels for power generation has significant health, environmental, and economic risks and is not a long-term solution to our energy needs. The paper concludes that a global transition to renewable energy is already underway. Renewable Energy offers an alternative to conventional sources and grants us greater control over future energy prices and supply. The energy choices we make during this pivotal moment will have huge consequences for our health, our climate, and our economy for decades to come.

Improving energy efficiency is one of the main ways to reduce energy pollution that leads to economic development, increasing energy access and better life. That can result in reducing fossil fuel use and growing clean energy supplies. The Gulf countries have as many renewable resources as hydrocarbons like sunshine, considerable wind resources, and geothermal. The economy of the Middle east deeplydepends on fossil fuel export. Declining fossil fuel supplies and rising energy prices are driving global energy supplies to renewables energies. Although the Middle East region, due to its special geographical features, has significant potential for the growth of renewable energy sources, they have not been developed yet. It overviews the energy situation and sustainability, economic potential of renewable energy, policies for energy systems over the recent decades in six resource-rich countries in the middle east. In addition, along with renewable energy technologies, possible ways to solve current environmental problems are recognized. The methodology of this work is PESTLE analysis of these countries' energy status to develop a long-term mechanism for sustainable and secure energy for the Middle East based on Political, Economic, Social, Technological, Legal, Environmental. Also, it identifies challenges that restrict the development of renewable energy technologies in the Middle East. By analyzing the status of energy in recent decades, the importance of implementation of effective energy policies to develop sustainable energy can be realized. Key words: energy source, sustainable future, renewable, effective policy, resource-rich countries.

Renewable energy is the most rapidly growing discipline in today’s business world and is commonly viewed as the main arena for research and development in various fields. This article summarizes the work and efforts of an educational project conducted at Prairie View A&M University (PVAMU). A major goal of the project was to design renewable energy laboratories and expose engineering students to clean energy technologies. Through this project, the investigators engaged students in renewable energy applications through hands-on experiments, encouraged interdisciplinary collaboration, and better prepared students to enter the energy workforce. Meanwhile, the project also benefited engineering educators by exploring effective teaching methods in energy education.

Measurement And Control

The real-time measurement and control of clean-energy power parameters provides a reliable platform for the performance test, a working state simulation of clean-energy power system and effective supports for the reasonable design of clean-energy power system. The whole measurement and control system is controlled by PLC and monitored by Kingview software. While mainly controlling the voltage and electric quantity of storage battery and motor speed, PLC is responsible for Modbus communication between the storage battery management system, the motor controller, the dynamometer controller and the industrial personal computer, Kingview is used for the real-time measurement and the controlling of system power parameters. The test shows that the measurement and control system is stable and reliable.
