In the context of the recent agreement at COP28 in Dubai and the current state of play of urban power systems – from G7 countries to emerging markets and developing economies – this report analyses the steps needed to achieve net zero emissions from electricity, and considers the wider implications for energy security, sustainability and affordability.
This conclusion comes from Chile: Leading the world to a 100% zero carbon power system, a new white paper from Wärtsilä. The study used advanced Plexos modelling to examine a variety of scenarios for Chile to affordably transition to
The carbon peak and carbon neutrality goals for China signify a critical time of energy transition in which energy resilience is a vital issue. Therefore, a comprehensive evaluation of urban energy system resilience

The findings show that Chilean carbon neutrality goals can be achieved with a smart energy system approach and that a 100% renewable energy system is feasible. Similarly, Osorio-Aravena et al. [35] analyzed the impact of renewable energy and sector coupling on the pathway towards a sustainable energy system in Chile. Authors find that
This paper presents recent accomplishments and gaps, mostly from an environmental perspective, on issues related to air pollution, the urban water cycle, and soil contamination, in the path being followed by Chile toward urban sustainability and resilience.
Urban areas currently accommodate over half of the world''s population and over 70% of global energy-related CO 2 emissions, with these statistics expected to be even higher by 2050 [1].As such, cities play a vital role in the global transition towards a low-carbon emission and sustainable energy future.
The aim of this study was to provide a systematic description of the narratives behind the resistance to the adoption of sustainable heating systems in two cities in southern Chile Air pollution is a major environmental risk in the urban environments and the widespread adoption of clean electricity and heating systems can have a significant
The FlexSUS project develops a decision-making tool to support smart urban energy systems based on digital solutions which enable municipalities and city planners to optimize their energy systems while implementing climate change mitigation efforts. The project builds on optimization of existing and planned energy systems and develops bridges across them in the form of data
Urban planning system of Chile In Chile, there are several instruments and mechanisms to organize and plan the urban and rural territory. Urban infrastructure and basic services, including energy. View List of Urban Themes. ECLAC participates in the launching event of the study "Circular Cities in Latin America and the Caribbean. Towards a
Urban energy system modeling frameworks (UESM), aiming at supporting decision making processes in formulating such strategies, should consequently reflect these outlooks in their modeling methods to provide strategic knowledge and insights to relevant stakeholders [13]. Several UESMs have already implemented modeling methods addressing
According to the latest report of the Intergovernmental Panel on Climate Change [1], sustainability and resilience have become crucial in today''s era, especially in the context of global change (e.g. temperature rise and climate change, biodiversity loss, environmental pollution, migration from rural to urban areas).For instance, sustainability practices such as
Unlock the potential of urban energy solutions to power sustainable cities. Discover innovative approaches for efficient and clean energy in urban environments. Through our comprehensive understanding of urban energy
Chile has experienced some of the world''s largest earthquakes, and has responded by creating an effective building code and seismic activity monitoring system. However, flooding and landslides disproportionately affect poorer communities, and segregation of resources limits available interventions.

Urban energy systems are pivotal in the global shift towards a climate-neutral future. Given the need for these systems to adapt to local conditions, designing them remains complex without standardized solutions. To address this, numerous software tools for energy system planning have been developed. Despite many scientific reviews on these
Climate change and increased urban population are two major concerns for society. Moving towards more sustainable energy solutions in the urban context by integrating renewable energy technologies
Cities consume over two-thirds of the world''s energy and have a unique role to play in the global energy transition across buildings, transport, heating/cooling, industry, and power grids (IEA, 2021). Cities can and must play a key role in the transition from a linear, centralized, fossil-fuel energy system to a hybrid model of centralized and decentralized, renewable, smarter, and
The challenge is to establish a hydroelectric axis that provides energy both to the Central Interconnected System and to the nearby communities, which channels sustainable community development, mitigates the effects caused by forest plantations and enables a road, a bridge and pedestrian and tourist connection to be built between the city of
The carbon peak and carbon neutrality goals for China signify a critical time of energy transition in which energy resilience is a vital issue. Therefore, a comprehensive evaluation of urban energy system resilience (UESR) is important for establishing a theoretical foundation. To this end, in this paper, 309 Chinese cities were evaluated using a

Cities contribute around 80% of global GDP and their associated emissions were responsible for a record 29 billion tonnes of CO 2 in 2023.; More than half of the 8 billion people alive today live in urban areas, and urbanisation is on an upward trend, with parts of Asia and Africa expected to continue to drive the proportion of the global population that is urbanised to around 70% by
Disruptions in energy supply, as a vital component of economic systems at different levels of economic activity, may cost "up to 1–2%" of the annual development potential of nations and cause serious damage to the effective functioning of their economies [43], [44].A list of some of climate and non-climate induced threats and challenges associated with the
By Fernando Saka, Executive Director of the Metropolitan Public Transport Authority in Santiago de Chile. When I was appointed as Executive Director of Santiago de Chile''s Metropolitan Public Transport Authority in 2018, I was entrusted with the mission to change the face of a bus system that serves three million trips a day.
The world''s increasing level of urbanization and the continuing restructuring of industry have resulted in great reliance on energy in cities. Different from the traditional energy system, urban energy systems present the complex characteristics of multi-mechanism coexistence, multi-dynamic intertwining, and multi-process coupling. Building an urban energy system that
UN-Habitat lead the urban energy sector by providing advices, policy reforms and energy solution for sustainable urbanization. UN-Habitat works with civil society organizations to reach out to the urban poor and address their energy concerns. We conduct joint training on affordable and clean energy system for lighting and cooking.
The PV potential is assed using spatio-temporal analysis of an urban area in Chile. In Concepción buildings can produced to 90% of the annual electricity demand with PV. On average, cities could produce 83% of their annual electricity demand. PV has already reached grid-parity in cities in Chile. 1. Introduction
Significant demand for space heating energy in central-south Chile due to the cold and humid climate . Wood biomass is the main energy fuel for residential space heating and cooking in south-central Chile . Wood biomass burning is the main source of PM 2.5 in cities of central-south Chile [54, 57].
In 2023, Chile counts 44 urban agglomerations of over 50,000 inhabitants, and 49% of the total population lives in the four largest urban agglomerations of Santiago, Valparaiso, Concepción, and La Serena , while urbanization is expected to reach 92% by 2050 .
For cities in the north of Chile, the solar radiation levels are high enough to yield a PV surplus on an annual basis, but also to reach a grid parity. In the center and south of Chile, with less solar radiation would still able to produce over 70% of their electricity consumption.
4.4. Solutions for soil pollution: implementing policies for soil management Soil is considered a non-renewable natural resource that, in Chile, is threatened mainly by physical and pollution degradation due to human activities.
Recently, Chile has launched several initiatives to increase resilience through a more comprehensive/holistic approach, in which territorial and urban planning are considered central elements to cope with natural hazards .
