Amidst the urgent climate change and energy shortage concerns, this study tackles the complex challenge of achieving sustainable development goals in the face of uncertain low-carbon building transformation paths and unclear energy/carbon trading strategies. Employing a comprehensive approach, the research reviews integrated techniques for low-carbon building transition, including energy conservation, clean energy adoption, demand response, and smart EV integration. The study also examines energy/carbon flows and trading within building systems and analyzes global decarbonization roadmaps.

Introducing the innovative concept of Carbon Storage (CS)-Factor, the research explores how urban planning can improve carbon neutrality through maintaining or restoring carbon storage in these new areas, with a specific focus on wooden construction. The study examines the carbon storage potential of future residential developments in the Uusimaa region, Finland, between 2022 and 2050.

Understanding public perceptions is crucial for the successful adoption of hydrogen as a clean energy alternative. Public poll data reveals that a significant percentage of the population holds neutral attitudes towards hydrogen technologies, highlighting the need for improved information and awareness campaigns. Socio-political acceptance, including trust in key stakeholders, plays a vital role in shaping public attitudes. Financial considerations and energy justice are also key factors in gaining market acceptance. By addressing these challenges and engaging communities, we can pave the way for a sustainable hydrogen-powered future.

As cities worldwide pursue greener and more sustainable public transportation solutions, the choice of the most economically viable bus technology becomes a pivotal decision for urban planners and policymakers. A recent study conducted in Perth has shed light on the true Total Cost of Ownership (TCO) for various bus technologies, including Hybrid, Hydrogen Fuel Cell (HFCB), Compressed Natural Gas (CNG), and conventional Diesel buses.

Financing has been a significant hurdle in realizing the renewable energy (RE) transition, but targeted incentives and strategies have proven constructive in encouraging the implementation of RE projects. The lack of public awareness about the benefits of RE and misconceptions about its associated costs have contributed to the reluctance of investors and energy consumers to make this shift. With COVID-19 pandemic-related lockdowns leading to a drop in fossil fuel consumption and prices, it is crucial that necessary actions are taken to ensure the shift to RE is not reversed

Interest in microgrid (MG) has grown in Australia in recent years due to concerns about energy security and resilience in the face of bushfires and climatic disruptions, and federal government funding has been provided for 37 pilot projects across the country. The Australian study investigates the current state of microgrid development in the country, explore the constraints to their development, and identify the likely future developments in this field.

A zero-carbon, reliable, and affordable electrical energy system can be achieved in Australia. A study found that the country’s greenhouse gas emissions could be reduced by 80% through the use of solar photovoltaics, wind turbines, existing hydropower, and biomass for power generation, while energy storage could be achieved through pumped hydro (off-river) and electric car batteries.

Hidden energy vulnerability refers to situations where households are at risk of harm from energy deprivation but are not captured by common indicators of energy poverty or do not request help. Through interviews with 32 intermediaries from health, housing and social service organisations, the paper develops six forms of hidden energy vulnerability: underconsumption entailing privation, incidental masking, disguised vulnerability, intentional concealment, failure to recognise the health risks of cold homes and ignored energy vulnerability.

The introduction of battery storage facilities in large, populous states in the National Electricity Market (NEM), specifically SA and VIC, has had a positive impact on the FCAS (frequency control ancillary services) market prices.

The rapid urbanization of the world’s population has led to an increasing need for effective city management. In light of this, the concept of the urbanome (developed by Morawska et al.) has been proposed as a theoretical framework for guiding the development and implementation of all-inclusive, interconnected and city-centric data systems.
