Shifting to clean energy—An editorial essay

Abstract

Interdisciplinary Reviews Energy and Environment is a well-regarded forum for publishing interdisciplinary science in energy and environment with 30 full issues published by now. Though these fields are by definition very broad in scope, the journal has succeeded to create a solid profile, which is both timely and relevant. Since its inaugural in 2012, the journal has consistently addressed solutions for mitigating the climate change, both in terms of technologies and policies. The journal has also succeeded in framing the interdisciplinarity in energy-environment by including perspectives from fields such as climate, technology, economy, geopolitics, policy analysis, planning, among others.Since the first issue was published, mitigation of climate change has been recognized by Wiley Interdisciplinary Reviews Energy and Environment as the key global challenge, which will affect the future of the modern society. We have addressed this quest through numerous reviews and in each of the previous editorials (Byrne & Lund, 2017;Lund & Byrne, 2014, 2016. Cutting emissions more strongly is timelier than ever.Though the path to meet the climate goals set in the Paris Climate Accord in December 2015 seems to be very challenging and nations will need to make much stronger commitments to reduce their greenhouse-gas emissions than so far, we also witness some positive signals. The International Energy Agency (IEA) (2017) reports that global emissions have stayed at about the same level for the last 3 years, but now these need quickly to be brought to a declining path to close the gap between the trend and the goal in emissions. It is also becoming evident that just cutting emissions will not be enough to keep global warming within the required limits, as noted by the Intergovernmental Panel on Climate Change (IPCC) during its COP 23 meeting in Bonn in November 2017. Regarding to the Bonn summit, The Economist (2017) reported on "negative emission technologies," which could help in extracting CO 2 from the atmosphere, and referred in this context to a recent paper in Wiley Interdisciplinary Reviews Energy and Environment by Wilcox and coworkers (2017). This demonstrates the importance of high-level science analysis in supporting the formulation of policies to cut emissions, which the journal can evoke. We find in the journal issues from 2017, a range of other interesting papers that relate to extracting CO 2 from the atmosphere or turning CO 2 into fuel, such as electrochemical reduction of CO 2 (Malik, Singh, Base, & Verma, 2017), or use of low-grade residual biomass from agriculture and forestry into synthetic fuels and chemicals (Dahmen et al., 2017) (the carbon neutrality of bioenergy is debated, but it seems that bioresiduals from industrial processes may be one of the most sustainable bioenergy alternatives).We positively notice the increasing market penetration of clean energy technologies. New energy technologies such as solar and wind power are becoming the mainstream technologies of the future power system, as noted ...

Competitive cross‐voltage level procurement of reactive power considering reliable capacity from wind and photovoltaics

“…Systems with high shares of VRPP as analyzed in Holttinen () are a consequence of the shift toward clean energy (Lund & Byrne, , see also Hasanuzzaman, Zubir, Ilham, & Seng Che, ; Smith et al, ). Most VRPP installed today can provide controllable Q only at times exceeding a certain minimum feed‐in threshold.…”

“…1.1 | Relevance of reliable Q procurement for systems with high shares of VRPP Systems with high shares of VRPP as analyzed in Holttinen (2012) are a consequence of the shift toward clean energy (Lund & Byrne, 2018, see also Hasanuzzaman, Zubir, Ilham, & Seng Che, 2017;Smith et al, 2013 (24/7) Q provision from VRPP is technically feasible and commercially available. Owing to the resulting benefits of 24/7 Q provision to the system, Holttinen et al (2016) suggest to investigate whether this capability should become a mandatory requirement of network connection codes.…”
