Renewable and sustainable energy has an evolving story as the ongoing trade war in the word is influencing crude oil prices. Moreover, the global warming is an inevitable consequence of the worldwide increasing rate of fossil fuel utilization which has persuaded the governments to invest on the clean and sustainable energy resources. In recent years, the cost of green energy has tumbled, making the price of renewables competitive to the fossil fuels. Although, the hydrogen fuel is still extremely expensive compared to the crude oil price, investigations about clean hydrogen fuel production and utilization has been developed significantly which demonstrate the importance of the hydrogen fuel in the future. This article aims to scrutinize the importance of green hydrogen fuel production from solar/wind energy.

To reduce reliance on fossil fuels and increase demands for clean energy technology worldwide, there is currently a growing interest in the use of fuel cells as energy-efficient and environmentally-friendly power generators. With this inevitable depletion, fossil fuels will not be able to respond to energy demand for future. Among all major types of fuel cells, hydrogen fuel cells (HFCs) are in the forefront stage and have gained substantial attention for vehicle and portable applications, which is composed of a cathode, an anode, and a PEM. The heart of the fuel cells is membrane electrode assembly (MEA). An electro-deposition technique for preparing the nano-catalyst layer in PEMFCs has been designed, which may enable an increase in the level of Pt utilization currently achieved in these systems. Functionalization process has been done using a mixture of concentrated nitric acid and sulfuric acid in refluxing condition. The hydrocarbon-based polymer membrane has been used as electrolyte part.

The Ontario Government passed the Ontario Green Energy and Green Economy Act in 2009. The Act promoted wind turbines and solar panels as a major component of the energy supply for the Province of Ontario as a replacement for coal-fired electricity generation plants. This article provides an economic assessment of the rationales that were offered for this policy, specifically, that the Act would help the Government of Ontario reduce the province’s reliance on fossil fuels, reduce carbon emissions, and stimulate the economy through the creation of jobs. The effects of the policy on the cost of electricity in the province are also considered. The analysis concludes that the Act will not reduce the Province of Ontario’s reliance on fossil fuels due to the inefficiency and unpredictability of wind turbines, ultimately leading to the need to use energy from more readily available sources of electricity such as gas. The need for fossil fuel backup also limits the potential to reduce the green house gas emissions. Keywords: Ontario Green Energy and Green Economy Act (2009); renewable energy; economic review

<p><em>The development of investment in the Islamic capital market, especially the Jakarta Islamic Index (JII) as a percentage, experienced significant development, and it is because the Islamic index uses Islamic principles and procedures. The phenomenon of the trade war between the United States and China has an impact on macro variable fluctuations, which can empirically influence the growth of the sharia index. For this reason, this study aims to analyze the impact of change due to the trade war sentiment. Macroeconomic variables used in this study are the USD / IDR exchange rate, the CNY / IDR exchange rate, inflation, Crude oil WTI, and ICP Crude oil. This study uses a vector autoregression analysis (VAR) technique. Stationarity test using the Augmented Dickey-Fuller test (ADF test) and the Philips-Perron Test. The analysis shows that there is an influence between changes in exchange rates and changes in crude oil prices on the return of the Jakarta Islamic Index (JII) in the range of research data periods used.</em></p>

The Cost

The increasing demand for energy threatens the earth with climate change due to emission of greenhouse gases from the burning of fossil fuels. This has been the major driver for green energy. Renewable energy has the potential to reduce the negative effects of energy production on the environment at a global scale. However, the technology to harness the energy from renewable sources have only been well developed for the electricity market. Expanding the scope to supply other markets and sectors would lead to increase in demand on rare earth minerals which will reciprocally create negative environmental and socio-economic impacts.  In order to mitigate such impacts, strong regulatory policies will be required to control different aspects of renewable energy sources, the scale of production and footprint on the environment. Recycling renewable energy technology is a step in the right direction. However, the cost of recycling is found to be 5 times the cost of mining. This would affect the price of energy generated from renewable energy sources on a long run. A shift from fossil fuel would imply at least 20 trillion dollars in stranded assets which would trigger a financial collapse. This collapse would possibly lead to the complete loss of the oil, gas and coal industries, power producers, insurance companies and banks that hold loans for these industries.

Human beings share the same community in which the usage of energy by fossil fuels leads to deterioration in the environment, typically global warming. When the temperature rises to the critical point and triggers the continual melting of permafrost, it can wreak havoc on the life of animals and humans. Solutions could include optimizing existing devices, systems, and platforms, as well as utilizing green energy as a replacement of non-renewable energy. In this special issue “Artificial Intelligence for Smart and Sustainable Energy Systems and Applications”, eleven (11) papers, including one review article, have been published as examples of recent developments. Guest editors also highlight other hot topics beyond the coverage of the published articles.

The aim of the work is to analyze targets on the transition to 100% renewable energy sources (RES) existing in different countries of the world as well as strategies for their achievement. The task of the work is to identify the most promising directions and develop appropriate recommendations for Ukraine. The global trend is setting targets for the transition to 100% RES, at least in some energy sectors, developing appropriate strategies and their implementation. Over the last decade, the cost of renewable energy has been steadily declining, making RES more competitive with fossil fuels in many parts of the world. Today, more than 50 countries, hundreds of cities and regions in one form or another have committed to switching to 100% RES. Most often it is about achieving 100% of renewable electricity. So far, at least 52 cities and regions have achieved their targets for the transition to 100% RES. Of these, 41 are located in Europe and 9 are located in the United States. About 2/3 of these targets relate only to renewable electricity. In Ukraine, the official targets for the development of RES are set out in the National Renewable Energy Action Plan until 2020 and in the Energy Strategy of Ukraine until 2035. Recently, a draft Concept of the “green” energy transition of Ukraine until 2050 was developed, which sets the goal of achieving a climate-neutral economy by 2070. One of the main directions of decarbonization of the economy is the development of RES in combination with increasing energy efficiency and energy saving. It is necessary to resume completing the document with the inclusion of reasonable long-term goals to achieve 100% RES in certain energy sectors and in the whole energy balance of Ukraine.

Increasing shares of variable renewable electricity (VRE) generation are necessary for achieving high renewable shares in all energy sectors. This results in increased excess renewable electricity (ERE) at times when supply exceeds demand. ERE can be utilized as a low-emission energy source for sectorcouplingthroughhydrogenproductionviaelectrolysis, whichcanbeuseddirectlyorcombined with a carbon source to produce electrofuels. Such fuels are crucial for the transport sector, where renewable alternatives are scarce. However, while ERE increases with raising VRE shares, carbon emissions decrease and may become a limited resource with several usage options, including carbon storage (CCS). These counteracting effects for the electrofuel production have not been analysed before. Here we perform a model based analysis for the German case until 2050, with a general analysis for regions with a high VRE reliance. Results indicate that ERE-based electrofuels can achieveagreenhousegas(GHG)abatementof74MtCO2eqyearly(46%ofcurrentGermantransport emissions) by displacing fossil fuels, at high fuel-cell electric vehicle (FCEV) shares, at a cost of 250320 € t CO2eq−1. The capital expenditure of electrolysers was found not to be crucial for the cost, despitelowcapacityfactorsduetovariableEREpatterns. Carbonwilllikelybecomealimitingfactor when aiming for stringent climate targets and renewable electricity-based hydrocarbon electrofuels replacing fossil fuels achieve up to 70% more GHG abatement than CCS. Given (1) an unsaturated demandforrenewablehydrocarbonfuels,(2)asaturatedrenewablehydrogendemandand(3)unused ERE capacities which would otherwise be curtailed, we find that carbon is better used for renewable fuel production than being stored.<br>
