Short-Term Electricity Demand Forecasting
Electricity demand forecasting plays a significant role in energy markets. Accurate prediction of electricity demand is the key factor in optimizing power generation and consumption, saving energy resources, and determining energy prices. Integrating energy mix scenarios, including solar and wind power, which are highly nonlinear and seasonal, into an existing grid increases the uncertainty of generation, creating additional challenges for precise forecasting. Artificial Intelligence (AI)-based deep learning models can effectively handle the information of long time-series data. Based on patterns identified in datasets, various scenarios can be developed.

Triboelectric Nanogenerator Network for Harvesting Ocean Blue Energy
The utilization of abundant blue energy in the ocean could greatly contribute to achieving carbon neutrality. However, the unsolved economic and technical challenges of traditional technologies for harvesting blue energy have resulted in slow progress. Triboelectric nanogenerators (TENGs), as a new approach for converting mechanical energy into electricity, have great potential for blue energy harvesting, which can be connected as networks with different numbers of units for varying scales of energy harvesting. Anchoring strategies of devices and networks are also discussed. The development of TENG networks could provide an effective solution for large-scale ocean blue energy harvesting, which can also serve as an in-situ energy station or power source for self-powered systems, supporting various marine equipment and activities.

Stability and Thermal Conductivity of MWCNT-Based Nanofluid
A nanofluid consisting of 0.5% MWCNTs, water (base fluid), and CTAB (surfactant) was selected with a sonication time of three and quarter hours, considering that these preparation conditions were practically the best. This fluid was circulated in an installed outdoor, weather-exposed PVT system. Experiments were carried out in the harsh weather conditions of Baghdad, Iraq, to test the effectiveness of the PVT system and the nanofluid.

Preparing Public Opinion to Accept Distributed Energy Systems
Global energy consumption has reached unprecedented levels over the last century due to population growth and economic growth. There have been significant changes in the global energy economy to reduce greenhouse gas emissions and air pollutants. Due to this trend, many countries around the world are promoting electric technologies as fuel-saving alternatives. Israelis know too little about smart meters, energy storage systems, and other modern power grid technology, which enables a decentralized approach to energy management referred to as distributed energy systems (DES). Using distributed energy systems to generate energy on-site and manage loads can reduce costs, improve reliability, and secure revenue. An effective public education program can help prepare public opinion and reduce barriers to smart use and energy efficiency in the home.

Tin Halide Perovskite-Based Solar Cells
The excellent optoelectronic properties of tin halide perovskites (Sn-PVKs) have made them a promising candidate for replacing toxic Pb counterparts. Concurrently, their enormous potential in photon harvesting and thermoelectricity applications has attracted increasing attention. The optoelectronic properties of Sn-PVKs are governed by the flexible nature of SnI6 octahedra, and they exhibit extremely low thermal conductivity. Due to these two contradictory properties, they are equally explored in solar cell as well as thermoelectric devices.

Fuel Cell Products for Sustainable Transportation
Hydrogen and fuel cells have gained attention as a viable alternative energy system. In general, fuel cells work with fuels like hydrogen, methanol, or natural gas to convert the chemical energy in the fuel into direct current (DC) without intermediate combustion, as is the case with conventional engines. Their improved efficiency and minimal emissions make fuel cells a candidate for a sustainable source of energy technology for the future. The type of fuel cell, costs of raw materials, and methods of manufacturing determine the fuel cell market and hence the transition towards the hydrogen economy.

Identification of Challenges for Second-Life Battery Systems
Lithium-ion batteries (LIBs) have been proven to be increasingly popular and are the solution of choice for many companies and business models around the world. One major question for battery owners is how to deal with returning batteries if they still contain sufficient capacity for operation. In this case, those energy storages can still be used in different, less demanding second-life applications, such as stationary battery storage systems, contributing to increased product sustainability and economic benefits at the same time. However, the second-life business model is still at an early stage of development due to the young EV market in combination with long vehicle lifetimes. As a consequence, there are several barriers in various thematic fields, complicating the rededication process for LIBs.

Implementation of PV Technology in Smart Grids
Photovoltaic distributed generation (PVDG) corresponds to the PV technology with the final goal of self-consumption, and it is generally located near the loads. PVDG support is a central topic when it comes to climate and energy policies, not only because of the environmental benefits that this technology brings, but also due to its social benefits, including the creation of new jobs. In fact, from 2009 to 2017, the PV modules’ cost decreased by over 85%—as compared with the price in 2009—which resulted from support schemes and improvements in technological competitiveness.
