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.

This review focuses on how culture can complicate and impede attempts at promoting more efficient, more sustainable, and often more affordable forms of mobility as well as energy use in homes and buildings. In simpler terms: it illustrates the cultural barriers to a low-carbon, low-energy future across 28 countries. Rather than focus on energy supply, it deals intently with energy end-use, demand, and consumption.

Pathways towards a defossilated sustainable power system for West Africa within the time horizon of 2015–2050 is researched, by applying linear optimisation modelling to determine the cost optimal generation mix to meet the demand based on assumed costs and technologies in 5-year intervals. Six scenarios were developed, which aimed at examining the impact of various policy constraints such as cross-border electricity trade and greenhouse gas emissions costs.

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.

This paper attempts to investigate the impact of economic growth and CO2 emissions on energy consumption for a global panel of 58 countries using dynamic panel data model estimated by means of the Generalized Method of Moments (GMM) for the period 1990-2012. We also estimate this relationship for three regional panels; namely, from Europe and North Asia, Latin America and Caribbean, and Sub-Saharan, North African and Middle Eastern. The empirical evidence indicates significant positive impact of CO2 emissions on energy consumption for four global panels.

This article shows that research in the design of 100% renewable energy systems in scientific articles is fairly new but has gained increasing attention in recent years. In total, 180 articles published since 2004 have been identified and analysed. Many of these articles have a predominant focus on the electricity sector. However, an increasing number of studies apply a cross-sectoral holistic approach on the entire energy system.

Electricity systems based on renewables have an increasing demand for flexibility. This paper considers the potential of power-to-gas to provide flexibility and enhance system integration of renewables. Existing research on power-to-gas typically analyses the system effects of a predetermined power-to-gas unit without endogenising the investment decision. Moreover, insights related to market and portfolio effects of power-to-gas are rare. To this end this work presents a stochastic electricity market model.

Reductions in carbon emissions have been a focus of the power sector. However, the sector itself is vulnerable to the impacts of global warming. Extreme weather events and gradual changes in climate variables can affect the reliability, cost, and environmental impacts of the energy supply. This paper analyzed the interplay between CO2 mitigation attempts and adaptations to climate change in the power sector using the Long-range Energy Alternative Planning System (LEAP) model.

Global warming and the acute domestic air pollution in China have necessitated transition to a sustainable energy system away from coal-dominated energy production. Through a systematic review of the national policy documents, this study investigates the policy mix adopted by the Chinese government to facilitate its energy transition and how that policy mix has evolved between 1981 and 2020. The chronological analysis emphasizes two dimensions of temporal changes in the policy mix: (1) changes in the policy intensity and density, and (2) the shift in policy instrument combinations.

In this paper, an integrated blockchain-based energy management platform is proposed that optimizes energy flows in a microgrid whilst implementing a bilateral trading mechanism. Physical constraints in the microgrid are respected by formulating an Optimal Power Flow (OPF) problem, which is combined with a bilateral trading mechanism in a single optimization problem. The Alternating Direction Method of Multipliers (ADMM) is used to decompose the problem to enable distributed optimization and a smart contract is used as a virtual aggregator.
