Dear colleagues,

In recent times, a surge in human activity within the environment has been evident, propelled by extensive technological utilization, mining exploration, industrialization, and small-scale endeavors vital for human survival and leisure. These multifaceted forms of exploitation have led to detrimental environmental consequences, manifested through climate change, extreme weather events, and direct ramifications on human health, including the onset of diseases and pandemics. Key global initiatives, notably spearheaded by the United Nations such as the Intergovernmental Panel on Climate Change (IPCC), Conference of the Parties (COPs), and various summits, have been pivotal in formulating strategies to mitigate these environmental risks, resulting in landmark agreements like the Paris Accord and the 17th Sustainable Development Goal (SDG17). In the pursuit of continued survival and well-being, despite the abundance of resources, there persists an escalating demand for energy consumption. The challenge lies in energy conservation, particularly in the adoption of sustainable and efficient energy conservation technologies (SEECT). 

A myriad of technologies has been engineered for both energy generation and conservation. This spectrum encompasses advancements such as LED technology, solar energy systems, effective insulation, electric vehicles, cogeneration technologies, small-scale hydropower, sensors, infrastructural automation, intelligent energy management systems, and wind turbines. Concerning batteries for electrical energy conservation, innovations traverse through historical epochs to contemporary times, encompassing the development of sulfur-ion, sodium, lithium, iron-lithium, nickel-cadmium, nickel-metal-hydride, flow, lead-acid, and zinc-carbon batteries. Nonetheless, the focal point of this section revolves around the identification and mapping of research endeavors directed towards more efficient and sustainable energy conservation technologies, with a pronounced emphasis on green and nanotechnology-based solutions.

We are looking forward to your contributions.
