Fuel cells convert the chemical energy of reactants (hydrogen, air) into water and exhaust heat, thus providing clean energy generation for both stationary and transport uses. In transportation, fuel cells are particularly useful for long-haul heavy-duty vehicles thanks to the shorter re-fuel...

Anthropogenic environmental pollution has become a global concern due to its profound impact on Earth's ecosystems. This study examines the interrelation between energy resources (both renewable and non-renewable), economic growth, and CO2 emissions across G-20 countries, using historical data...

Hydrogen energy systems (HES) are increasingly recognized as pivotal in cutting global carbon dioxide (CO2) emissions, especially in transportation, power generation, and industrial sectors. This paper offers a comprehensive review of HES, emphasizing their diverse applications and economic...

The role of distributed energy resources (DERs) in future power systems is becoming increasingly important due to the ongoing transformation of the electricity sector towards carbon neutrality and higher decentralization. As changes in the demand side continue, such as the adoption of electric...

This article presents the results of the research on energy activities in Romania by highlighting the variants of the mix of energy resources, the mix of production alternatives, and ways of energy consumption. The uneven distribution of resource ownership in EU member states is a comparative...

Management commitment and perception of the need to adapt and adjust hotel operations in the face of the energy crisis on the path of reducing energy consumption under the REPowerEU plan have been little addressed in the literature, although it is a very topical issue. This research fills this...

Sustainable energy is paramount in advancing initiatives about energy conservation and transitioning towards clean, secure, and efficient energy sources. The research objective is to assess the impact of alterations in energy intensity on the socioeconomic development of a country. The study...

Klappentext: "Energy history is an approach to understanding the past that takes changes in the human exploitation of Earth's energies as its object of inquiry. This interdisciplinary field documents and analyzes how humans thought about, harnessed, stored, and exploited stocks and flows of...

Ideally, to reduce energy insecurity, a nation needs to deploy a range of renewable energy (RE) sources. For Central Asian economies, renewable sources appear to be a rational choice; yet, the deployment of renewables is limited and varies substantially by country. Conventional statistics for RE...

Energy return on investment (EROI) is a biophysical and ecological economics concept that is useful to think about how organisms, ecosystems and societies must obtain enough surplus energy returned from energy gathering activities to live, reproduce, and thrive. EROI can help us overcome the...

Policy changes that encourage non-fossil fuel energy means increased reliance on batteries and other technologies that must develop rapidly. This article focuses on batteries, noting that key inputs come from corrupt countries, so little of the benefits of exports flow to citizens, and many key...

The deployment of behind-the-meter energy resources is set to increase in the next decade. Yet, utilities are not ready to safely manage these resources owing to the lack of visibility into behind-the-meter installations. To address this problem, we propose an unsupervised method to decompose a...

Uncertainty in the energy sector of Pakistan has contributed to the necessity of effective electricity planning that can minimize given market risks and discourage the use of stand-alone generating costs. To this end, this paper leverages the mean-variance portfolio theory to design an efficient...

The continued development of distributed energy resources (DER), information and communications technologies is enabling a greater number of parties to participate in electricity markets. This review explores the various methods that DERs may utilize to participate in electricity markets, the...

Renewable energy (RE) is the key element of sustainable, environmentally friendly, and cost-effective electricity generation. An official report by International Energy Agency (IEA) states that the demand on fossil fuel usage to generate electricity has started to decrease since year 2019, along...

Ever-increasing coupling of energy and mobility sectors is under way in our cities. However, whether and how to use such coupling to optimize the portfolio and operations of urban energy assets has rarely been studied. We fill this gap by studying "omni-sharing,'' which is a novel business model...

Die Wirtschaftspolitik steht angesichts der Schwere der Energiepreiskrise vor großen Herausforderungen. Mit den drei Entlastungspaketen hat die Regierung zwar einige wichtige Impulse gesetzt, eine stringente Linie lässt die Wirtschaftspolitik jedoch vermissen. Sämtliche Maßnahmen sollten...

As the world's third-biggest emitter of greenhouse gases, India has pledged to achieve net-zero carbon emissions by 2070. The electricity sector is at the forefront of decarbonisation initiatives and distributed energy resources (DERs) are expected to play a key role in enabling the country to...

This study aims to stimulate discussion of the country’s policy framework for managing existing and potential energy resources. It argues that a well-designed Sovereign Wealth Fund (SWF) can positively transform the country’s management of proceeds from energy resources as well as bolster...

The Comprehensive Development Plan aims to create a sustainable development space and generate opportunities to improve the quality of life of the people of El Salvador, Guatemala, Honduras and south-southeast Mexico, thus making migration a choice rather than an obligation. This is an joined up...
