In an era characterised by unprecedented environmental challenges and the devastating impacts of climate change, our drive towards finding sustainable energy solutions is of paramount importance. There is a need to rapidly move away from fossil fuel use and a radical departure from conventional energy sources. The utilisation of renewable energy from solar, wind, marine and geothermal sources, and the exploitation of sustainable fuels, offer potential benefits from an environmental, societal, and economic perspective.

The urgency of this transition is increasingly acknowledged and cannot be realised without further research and innovation along the value chain, from conversion, storage, distribution, and end-use. The displacement of fossil fuels is extremely difficult because of their excellent volumetric and gravimetric energy density and their ease of use. The current renewable energy sources and alternatives fuels have challenges, for example with respect to cost, safety, security of supply and contribution to a resilient energy system. It is also clear that we need to strive to use our energy resources in the most efficient and effective ways possible, reducing energy demand in transport, industry, commerce, buildings, and every aspect of our activity.

Green Energy and Sustainability (GES; ISSN 2771-1641) is a peer-reviewed, Open Access journal which provides a comprehensive dissemination platform for the global energy research community. This free platform is dedicated to critical review, challenging existing knowledge and understanding. It strives to showcase cutting-edge research and analysis, facilitate the exchange of new insights and expert views, and emphasise crucial aspects relating to a transition towards a green energy economy. All review and original research articles, case studies, communications, and short notes have no length or colour restrictions, and undergo a rigorous peer-review process so that GES remains a trusted and authoritative research publication and a valued academic resource for researchers, technology developers, policy makers and all those who have a stake in green energy and its impact on sustainability.

GES enthusiastically encourages submissions on relevant topics from the research community worldwide and supports a multidisciplinary approach to sustainable energy challenges. Committing to inclusivity and diversity, the journal aims to create an open environment for critical thinking and collaborative research. It will publish, freely available articles, highlighting different approaches and novel ideas, state-of-the-art knowledge, best practice and experiences.

We are focussed on stimulating debate and discussion, promoting meaningful change, and achieving global impact. Please join us on the journey towards Green Energy and Sustainability.
