“…Using state-of-the-art methods is key in science, especially in modelling 100% RE scenarios, which has seen several hundreds of studies in the last years (for example each of these reviews [16][17][18][19][20][21][22] have dealt with dozens of studies). One of the drawbacks of the study in question, is its low temporal resolution: eight typical days corresponding to weekday and weekend of the four seasons.…”

This paper is a commentary on ‘Decarbonizing the Chilean Electric Power System: A Prospective Analysis of Alternative Carbon Emissions Policies’ –an article published by Babonneau et al. in the Energies Journal. On the one hand, our aim is to point out and discuss some issues detected in the article regarding the literature review, modelling methods and cost assumptions, and, on the other hand, to provide suggestions about the use of state-of-the-art methods in the field, transparent and updated cost assumptions, key technologies to consider, and the importance of designing 100% renewable multi-energy systems. Furthermore, we end by highlighting suggestions that are key to modelling 100% renewable energy systems in the scientific context to contribute to expanding the knowledge in the field.

“…In very general terms, there are three non-exclusive approaches to stopping climate change: 1) Reduce human GHG emissions, 2) Protect ecosystems to sustain natural GHG sinks, and 3) Attempt to control the Earth's energy balance through geoengineering. The first two approaches are feasible, cost-effective, and come with a wide array of co-benefits (Foley et al, 2011;Breyer et al, 2021;Chapin et al, 2022). For example, eliminating fossil fuel burning could prevent 10.2 million premature deaths each year and add US$10 trillion annually in economic benefits from improved air quality (Errigo et al, 2020;Shindell et al, 2021;Vohra et al, 2021;Abbott B., 2022).…”

“…Thankfully, recent breakthroughs in renewable energy production, transmission, and storage now allow much faster decarbonization than previously believed possible (Bogdanov et al, 2021;Victoria et al, 2021;Jacobson et al, 2022). The costs of solar photovoltaics and wind turbine have plummeted 91 and 71%, respectively since 2009, now providing the cheapest and cleanest electricity ever available to humankind (Abbott et al, 2021a;Breyer et al, 2021;Abbott B., 2022). Global markets have already responded, with renewables constituting 90% of all new electricity capacity built in 2021 (IEA, 2021a) and 95% of all projected growth through 2025 (IEA, 2021b).…”

“…Mature technologies now allow electrification of nearly the entire economy (transportation, manufacturing, agriculture, etc. ), with developing technologies on track to allow full decarbonization before 2040 (Breyer et al, 2021;Jacobson et al, 2022). If the global community commits to sustaining this ongoing transition, the clean and abundant energy will also bring down costs of direct air carbon capture and storage (DACCS), one of the few scalable and sustainable geoengineering approaches (Breyer et al, 2020).…”

“…If the global community commits to sustaining this ongoing transition, the clean and abundant energy will also bring down costs of direct air carbon capture and storage (DACCS), one of the few scalable and sustainable geoengineering approaches (Breyer et al, 2020). The combination of abrupt global decarbonization and renewable DACCS could enable a return to Holocene-like conditions by the end of the century (Breyer et al, 2021;Abbott B., 2022). Now that the technology and economics for rapid decarbonization and atmospheric drawdown of CO 2 are in place, meeting our moral responsibility to restore the Earth's climate is in reach.…”

Climate change is an existential threat to the vast global permafrost domain. The diverse human cultures, ecological communities, and biogeochemical cycles of this tenth of the planet depend on the persistence of frozen conditions. The complexity, immensity, and remoteness of permafrost ecosystems make it difficult to grasp how quickly things are changing and what can be done about it. Here, we summarize terrestrial and marine changes in the permafrost domain with an eye toward global policy. While many questions remain, we know that continued fossil fuel burning is incompatible with the continued existence of the permafrost domain as we know it. If we fail to protect permafrost ecosystems, the consequences for human rights, biosphere integrity, and global climate will be severe. The policy implications are clear: the faster we reduce human emissions and draw down atmospheric CO2, the more of the permafrost domain we can save. Emissions reduction targets must be strengthened and accompanied by support for local peoples to protect intact ecological communities and natural carbon sinks within the permafrost domain. Some proposed geoengineering interventions such as solar shading, surface albedo modification, and vegetation manipulations are unproven and may exacerbate environmental injustice without providing lasting protection. Conversely, astounding advances in renewable energy have reopened viable pathways to halve human greenhouse gas emissions by 2030 and effectively stop them well before 2050. We call on leaders, corporations, researchers, and citizens everywhere to acknowledge the global importance of the permafrost domain and work towards climate restoration and empowerment of Indigenous and immigrant communities in these regions.

Multiple energy‐related crises require a fast transition towards a sustainable energy system. The European Green Deal aims for zero CO2 emission by 2050, while accelerating climate change impacts obligate a faster phase‐out of fossil fuels. Energy transition studies for Europe at and near 100% renewable energy are used as a benchmark for two newly introduced scenarios for Europe reaching zero CO2 emissions by 2050 and 2040. A technology‐rich energy system model was applied in hourly resolution for Europe in 20 interconnected regions and in full sector coupling covering all energy demands. The results reveal a cost‐neutral energy transition towards 2050 based on declining levelised cost of electricity and a pathway with 9% higher energy costs leading to 17% lower total CO2 emissions with an accelerated energy transition by 2040. The two scenarios find shares of solar photovoltaic (PV) in total generation of 61%–63% by 2050, the highest ever estimated for Europe, still below the highest global average shares ranging between 75% and 77% form three independent studies. The central energy system components are solar PV, wind power, batteries, electrolysers and CO2 direct air capture for carbon capture and utilisation. The core characteristic of the European energy future may be best described by a power‐to‐X economy, which may evolve on the global scale to a solar‐to‐X economy.
