This paper cautions that the adoption of electric vehicles with the aim of reducing greenhouse gas emissions must balance that beneficial effect against increased water consumption. It recommends battery electric vehicles charged by solar energy as the best solution.

Assessment of the food-water-energy nexus suitability of rooftops. A methodological remote sensing approach in an urban Mediterranean area
This work established a framework to identify and analyze the technical feasibility of roofs for integrating urban agriculture, rainwater harvesting, and photovoltaic systems using various remote sensing. The framework was applied to a region north of Barcelona. Three levels of solar access requirements for tomatoes, leafy crops, strawberries, and microgreens were established. The case study included compact and disperse urban forms, residential and nonresidential building uses and various building typologies.

Background: Africa is undergoing both an environmental and an epidemiological transition. Household air pollution is the predominant form of air pollution, but it is declining, whereas ambient air pollution is increasing. We aimed to quantify how air pollution is affecting health, human capital, and the economy across Africa, with a particular focus on Ethiopia, Ghana, and Rwanda. Methods: Data on household and ambient air pollution were from WHO Global Health Observatory, and data on morbidity and mortality were from the 2019 Global Burden of Disease Study.

Healthcare-associated infections cause a massive burden for the health care system and the patients. Although the standard sterilization protocol with saturated steam (>121°C and >205 kPa) is effective, generating high-temperature and high-pressure steam is challenging without reliable access to electricity or fuel. While abundant solar energy is readily available, utilizing sunlight to generate steam beyond 100°C requires costly and bulky optomechanical components. In this work, we developed a stationary solar thermal device capable of providing the required saturated steam.

The new European Commission plans to raise the greenhouse gas (GHG) emissions reduction target from 40% towards 55% by 2030 and make Europe the first climate-neutral continent by 2050. Achieving this will require accelerated energy efficiency measures, deeper electrification of sectors currently consuming conventional fuels and the deployment of more renewables, faster. This opinion article looks specifically at the role of photovoltaics (PV), based on scenarios from the Commission's 2018 long-term strategy (LTS) for energy and climate.

A possibility of developing an environmental-friendly photovoltaic/thermal (PV/T) solar panel, which can shut high temperature radiation within a panel box, was experimentally confirmed. The panel has a decompression-boiling heat collector, which can absorb heat from the PV module and can keep the air and the cover glass inside the panel box at lower temperature by using lower boiling temperature of working fluid under vacuum condition. The panel also has an emboss-processed cover glass, which can totally reflect the high temperature heat radiation from the PV module within the panel box.

Soiling consists of the deposition of contaminants onto photovoltaic (PV) modules or mirrors and tubes of concentrated solar power systems (CSPs). It often results in a drastic reduction of power generation, which potentially renders an installation economically unviable and therefore must be mitigated. On the other hand, the corresponding costs for cleaning can significantly increase the price of energy generated. In this work, the importance of soiling is assessed for the global PV and CSP key markets.

21st Century Climate Change Impacts on Key Properties of a Large-Scale Renewable-Based Electricity System
Falling prices and significant technology developments currently drive an increased weather-dependent electricity production from renewables. In light of the changing climate, it is relevant to investigate to what extent climate change directly impacts future highly weather-dependent electricity systems. Here, we use three IPCC CO 2 concentration pathways for the period 2006–2100 with six high-resolution climate experiments for the European domain.

Toward supplying food, energy, and water demand: Integrated solar desalination process synthesis with power and hydrogen coproduction
The increase in population coupled with rising per capita income and associated change in consumption habits will put unprecedented stress on food, energy and water (FEW) resources. Sustainable and reliable fresh water supply is central for life and also for all sectors that support our existence. Uncertainty on water security prompted interest in investigation of renewable energy driven desalination processes. One particularly promising option is to produce fresh water from the two most abundant resources on earth: solar energy and seawater.

Progressing towards the development of sustainable energy: A critical review on the current status, applications, developmental barriers and prospects of solar photovoltaic systems in India
Equality between economic progress and environmental sustainability is essential for a developing country like India. In the present time, the economy of India is growing rapidly in a vibrant mode and an efficient way, which in turn demands huge uninterrupted energy supplies. The country's energy needs are met mostly by the usage of fossil fuels and nearly 70% of electricity is generated from coal based power plants. In India, nearly 840 million people depend on traditional biomass to satisfy their energy necessities.
