Feasibility of a 100% Global Renewable Energy System
Controversy exists as to whether renewable energy (RE) can provide for all the world’s energy needs. It is found that the energy that could be delivered by these two sources is much less than often assumed, for several reasons: The declining quality of inputs; the need for inclusion of uncounted environmental costs; the need for energy conversion and storage; and the removal of existing fossil fuel energy subsidies.

Large-Scale Hydrogen Production Systems Using Marine Renewable Energies
The electrochemical dissociation of water using renewable energies allows the production of green hydrogen and oxygen. The behavioral aging dynamics of the electrolyzer and fuel cell (FC) devices must be considered to increase the effectiveness and sustainability of the power-to-hydrogen and hydrogen-to-power systems. Their operation is greatly influenced by factors such as the temperature, dynamic current profiles imposed by the renewable energy sources (RESs), and gas pressure (in electrolyzers and FCs), which accelerate their degradation.

Energy Efficiency in a Global Context
Energy efficiency is, in principle, a simple idea: an output of human value, for example, vehicle-km traveled, divided by the needed input energy. Efficiency improvements are regarded as an important means of mitigating not only climate change, but also other environmental problems. Much has been written about energy efficiency, but it is mainly concerned with means for improving efficiency, or barriers to implementing higher energy efficiency. In contrast, this entry argues that the concept of energy efficiency needs to be broadened, both conceptually to include ethical considerations, and spatially, to include distant as well as local impacts.

Recycling and Reuse ECOSYSTEM
Daikin Europe N.V. (DENV), Daikin Central Europe (DACE), the National Technical University of Athens (NTUA) and the Society for Materials and Energy Applications (MAT4NRG GmbH) are the four partners of the consortium behind the Retradeables project that receives EU funding. The key objective of the ongoing project is to realise the first circular economy ecosystem to strongly promote the efficient management of used gases, offering sustainability and accountability to the HVAC-R industry and reducing environmental pollution stemming from F-gas emissions. This is exactly the mission of the so-called “3R ECOSYSTEM” that is currently under development to bring total innovation to the HVAC-R industry, adding value to used refrigerants that will be treated as an asset instead of a waste to be destroyed.

Overview of Metal-Ion Battery Recycling Methods
Metal-ion batteries (MIBs), particularly lithium- and sodium-ion ones (LIBs and SIBs, respectively), are an essential part of portable and stationary electronics due to their energy density characteristics and long-term cycling ability. The expected growth of the MIBs market unavoidably leads to the generation of tons of spent batteries, this in turn dictates the necessity of a proper life cycle management of used cells and packs.

Energy Accounting for a Renewable Energy Future
For millennia, humans relied almost entirely on renewable energy (RE), largely biomass, for their energy needs. Fossil fuels (FFs) have not only largely replaced RE, but have enabled a many-fold rise in total energy use. This FF dominance changed the way we think about and accounted for energy use. If (as at present) the world essentially continues to ignore climate change, eventual resource depletion will force conversion to RE and, perhaps, nuclear energy will once again have to provide most of the world’s energy use.

Urban Building Energy Modeling Using a Place-Based Approach
Urban building energy models present a valuable tool for promoting energy efficiency in building design and control, as well as for managing urban energy systems. However, the current models often overlook the importance of site-specific characteristics, as well as the spatial attributes and variations within a specific area of a city. This approach allows for a more in-depth understanding of the interactions behind spatial patterns and an increase in the number and quality of energy-related variables.

Bio-Swales in Hydrology, Water Quality, and Biodiversity
Bio-swales have gained significant attention as an effective means of stormwater management in urban areas, reducing the burden on conventional rainwater management systems. Bio-swales have the capacity to mitigate flood risk, reduce nonpoint source pollution, and enhance biodiversity. The performance of bio-swales is influenced by factors such as water quality, vegetation characteristics, substrate heterogeneity, and age, as identified by existing research. Nevertheless, critical knowledge gaps remain that need to be addressed in future research.

Integrated Approaches for Effective Utility Management
Water distribution systems are challenging to manage because they comprise complex networks with large numbers of interacting pipes, pumps, valves, and controls. These components are mostly hidden, usually of mixed ages and conditions, and management programs for maintenance and renewal are often inadequate. Despite these challenges and complexities, distribution systems are expected to deliver pressurized safe drinking water to households and other sites on a reliable basis. Comprehensive and integrated approaches to managing distribution systems are needed, but they face barriers due to the realities of variable management capacities in utility organizations around the world. The variation in these capacities to manage water utilities is a great barrier to improved management of all water subsystems, and it poses challenges to distribution system management because of their greater complexity. Another issue is posed by the difficulty of recruiting and equipping a capable workforce for the multiplexed problems of managing distribution systems.

Algae Biomass as Source of Liquid Fuels
Algae biomass is perceived as a prospective source of many types of biofuels, including biogas and biomethane produced in the anaerobic digestion process, ethanol from alcoholic fermentation, biodiesel synthesized from lipid reserve substances, and biohydrogen generated in photobiological transformations. Environmental and economic analyses as well as technological considerations indicate that methane fermentation integrated with bio-oil recovery is one of the most justified directions of energy use of microalgae biomass for energy purposes. A promising direction in the development of bioenergy systems based on the use of microalgae is their integration with waste and pollution neutralization technologies.

Barriers and Enables in Demand Response Performance Chain
The role of demand response increases considerably with a higher share of renewable energy sources in the energy mix, characterized with more frequent energy market price fluctuations due to mismatch between uncontrollable weather-dependent production and currently relatively inflexible energy consumption. Reallocation of energy consumption from high-price hours to lower price hours helps to avoid extra costs to the entire economy and ensures the possibility to minimize fossil-based energy generation, therefore contributing to the achievement of zero-emission goals.

Wind Turbines Operating under Hazard Environmental Conditions
Renewable energy use has accelerated due to global warming, depleting fossil fuel reserves, and stricter environmental regulations. Among renewable options, solar and wind energy have shown economic viability and global growth. Horizontal axis wind turbines offer promising solutions for sustainable energy demand. Since wind turbines operate in an open environment, their efficiency depends on environmental conditions. Hazard environmental conditions, such as icing, rainfall, hailstorms, dust or sand, insects’ collisions, increased humidity, and sea spray, result in degraded aerodynamic characteristics.
