concept Authors: ['Tessa Dunlop'] Energy efficiency is a popular policy strategy to reduce energy consumption and greenhouse gas emissions. The concept of energy efficiency is relatively simple - to use less energy for the same level of output. However, complexities emerge when applying efficiency concepts to real…

Improving energy efficiency is a critical way to solve energy shortage and environmental problems and achieve the goal of “double carbon”. As China expands imports and integrates into global value chains, can import trade improve energy efficiency? This topic is extremely important for solving current energy problems…

With the rapid growth rate of China’s economy, the extensive pattern of economic growth of “high energy consumption and low output” has magnified the constraints of energy issues on China’s economic development and environmental protection, which highlights the importance of improving energy efficiency. As one of the…

The energy transition is also about switching to electricity-based technologies such as heat pumps and electric mobility. They avoid heat as an intermediate step and are therefore much more efficient. This can significantly reduce the demand for primary energy in the future, which can then be fully covered by the…

The demand for energy has been increasing significantly worldwide. Consequently, carbon emissions have accelerated, since energy usage involves carbon dioxide. Given that the available energy has quantitative restriction feature, efficient usage of energy becomes crucial. Energy efficiency is expected to improve over…

Energy-poor households often compromise their thermal comfort and refrain from operating mechanical cooling devices to avoid high electricity bills. This is compounded by certain behavioral practices like retention of older, less efficient appliances, resulting in missed energy savings. Thus, the need to enhance…

Exergy efficiency is viewed as the degree of approaching reversible operation, with a value of 100 percent for a reversible process characterized by zero entropy generation or equivalently zero exergy destruction since Xdestroyed = T0Sgen. As such, exergy efficiency becomes a measure of thermodynamic perfection. There…

In this study, we conducted the conceptual design of a system aimed at delivering constant energy supply for a decarbonised urban mobility setting. To this scope, we designed two systems based on battery electrical vehicles (BEV) and fuel cell electric vehicles (FCEV). The supply is primarily provided by renewable…

Despite the growing emphasis on intelligent buildings as a cornerstone of sustainable urban development, significant energy inefficiencies persist due to suboptimal design, material choices, and user behavior. The applicability of integrated Building Information Modeling (BIM) and solarpowered environmental monitoring…

Most people don't know how much energy they are spending for different purposes and also they are unaware of potential electrical consumption reduction level they could make by changing their consumption behaviors or investing in new efficient technology products. Providing electrical consumption information to…

Recent and ongoing discoveries in the field of extracellular electron transport offer the potential to electrically power highly flexible, carbon-fixing microbial metabolisms and generate a rich variety of chemicals and fuels. This process, electrosynthesis, creates the opportunity to use biology for the low cost…

Second, we assess the energy efficiency of each state. By looking up scholarly resource, we decide to use the DEA model to evaluate energy efficiency. During the 50 years from 1960 to 2009, the average energy efficiency of Arizona, California, New Mexico and Texas are 0.997, 0.984, 0.983 and 0.987 respectively. The…

The highest intensity of photosynthesis is obtained under red light, but plants die or their growth gets disrupted if only red light is used. For example, Korean researchers [1] have shown that under pure red light the amount of the grown lettuce is greater than under a combination of red and blue light, but the leaves…

Agonists are classified by the strength at which they bind to their target sites (affinity) and their ability to activate receptors once bound to those sites (efficacy). Efficiency is a third fundamental agonist property that is a measure of the correlation between affinity and efficacy. Efficiency is the percent of…

Microbes which participate in extracellular electron uptake or H_2_ oxidation have an extraordinary ability to manufacture organic compounds using electricity as the primary source of metabolic energy. So-called electromicrobial production could be of particular value in the efficient production of hydrocarbon blends…

This paper addresses the challenge of decarbonizing global energy systems by proposing the Shibah Integrated Bio-Electro-AI CCUS-H2 Framework, a multidisciplinary approach that combines hydrogen production, storage, and utilization with carbon capture, utilization, and storage (CCUS). The framework tackles high costs…

Every ten years the photovoltaic market grows tenfold, driven by increasing cell efficiencies and lower manufacturing and installation costs. If the next decade maintains this trend it must be via a technological transformation: The first commercial silicon-based devices that exceed the 29.4% efficiency limit of…

The uphill energy transfer in photosystems implies input energy at higher wavelength leading to energy output at lower wavelength. Briefly, energy is uphill transported from photosystem I (PSI) to photosystem II (PSII), the latter having a lower wavelength emission. This uphill energy transport involves absorption of…
