Energy Transitions

Increasing recognition of the irrefutable urgency to address the global climate challenge is driving mitigation efforts to decarbonise. Countries are setting targets, technological innovation is making renewable energy sources competitive and fossil fuel actors are leveraging their incumbent privilege and political reach to modulate energy transitions. As techno-economic competitiveness is rapidly reconfigured in favour of sources such as solar energy, governance puzzles dominate the research frontier. Who makes key decisions about decarbonisation based on what metrics, and how are consequent benefits and burdens allocated? This article takes its point of departure in ambitious sustainability metrics for solar rollout that Portugal embraced in the late 2010s. This southwestern European country leads on hydro and wind power, and recently emerged from austerity politics after the 2008–2015 recession. Despite Europe’s best solar irradiation, its big solar push only kicked off in late 2018. In explaining how this arose and unfolded until mid-2020 and why, the article investigates what key issues ambitious rapid decarbonisation plans must address to enhance social equity. It combines attention to accountability and legitimacy to offer an analytical framework geared at generating actionable knowledge to advance an accountable energy transition. Drawing on empirical study of the contingencies that determine the implementation of sustainability metrics, the article traces how discrete acts legitimate specific trajectories of territorialisation by solar photovoltaics through discursive, bureaucratic, technocratic and financial practices. Combining empirics and perspectives from political ecology and energy geographies, it probes the politics of just energy transitions to more low-carbon and equitable societal futures.

Abstract This paper develops an integrated framework to study the socio-spatial and temporal dimensions of urban energy transitions to investigate the development and spread of solar energy technologies in urban China. A comparative analysis of three case studies of solar energy transitions in the cities of Foshan (in Guangdong), Rizhao (in Shandong), and Wuxi (in Jiangsu) demonstrates the framework’s applicability. The results map each city’s trajectory towards low carbon energy. Transitions result from dynamic interactions among central and local governments, solar manufacturers, solar installers, and residents. Alongside industrial strategies, locally-specific factors have a determining influence on the eventual outcomes.

AbstractThe role of chemical energy storage and solar fuels as key elements for the sustainable chemical and energy production is discussed in this concept paper. It is shown how chemical energy storage, with the development of drop-in carbon-based solar fuels, will play a central role in the future low-carbon economy, but it is necessary to consider its out-of-the-grid use, rather than being limited to be a tool for smart grids. Related aspects discussed are the possibility to: (i) enable a system of trading renewable energy on a world scale (out-of-the-grid), including the possibility to exploit actually unused remote resources, (ii) develop a solar-driven and low-carbon chemical production, which reduces the use of fossil fuels and (iii) create a distributed energy production, going beyond the actual limitations and dependence on the grid.

Urbanization In China

In order to back Low-Carbon Cities Plan, China’s urban renewal and the protection of traditional neighborhoods, and after literature searching and site survey, spatial evolution and site inspection in Huilongwo area, the authors point out that we should combine modern eco-technological methods such as solar energy application, reclaimed water system, ground source heat pump, solar energy application and so on with the protective measures of historical neighborhoods, and improving the living facilities of the Historic District. Only implant the modern ecological system into the historic context conservation, the city could be reaching the “sustainable development”. It’s a sound sample of urbanization in China.

The University

This study investigates 200 kWp roof-mounted solar photovoltaic system in a country where there is no legal, policy, and institutional framework to de-risk the solar energy market but present naturally conducive environment in the sun-drenched semi-arid country. The analysis of quantitative and qualitative data subject to interpretivist and positivist approaches paves the way to find out that the university, though created financial and environments values, has not addressed the risk associated with illiquid capital intensive investment and conventional financial metrics such as net present value, internal rate of return. Hence, it is recommended to manage the risk with four strategies including maintaining economic value added at 5% or more, leveraging the investment, and withdrawing a part of equity for reinvesting in diversified investment. The findings are significant for low carbon investors to identify opportunities and manage the risk in solar energy market. Energy engineers enable designing a system that meets the fundamentals of the business and environmental value.

Chemical production is set to become the single largest driver of global oil consumption by 2030. To reduce oil consumption and resulting greenhouse gas (GHG) emissions, carbon dioxide can be captured from stacks or air and utilized as alternative carbon source for chemicals. Here, we show that carbon capture and utilization (CCU) has the technical potential to decouple chemical production from fossil resources, reducing annual GHG emissions by up to 3.5 Gt CO2-eq in 2030. Exploiting this potential, however, requires more than 18.1 PWh of low-carbon electricity, corresponding to 55% of the projected global electricity production in 2030. Most large-scale CCU technologies are found to be less efficient in reducing GHG emissions per unit low-carbon electricity when benchmarked to power-to-X efficiencies reported for other large-scale applications including electro-mobility (e-mobility) and heat pumps. Once and where these other demands are satisfied, CCU in the chemical industry could efficiently contribute to climate change mitigation.

Solar powered intellective vehicles (SPIVs) not only focus on energy saving and environmental protection, but also have finer feasibility. The design of extended range in SPIVs is a kind of the important directions that low carbon green vehicles will be design in future. We will reflect demanding design of extended range shoot to convert the target design level. The optimal design is actualized for photovoltaic array collocation of solar energy in SPIVs. The “zero oils consume, zero exhaust, increment drives distance” demand of SPIVs are carry out by the vehicle with design carries to net electrical source system of extended range.
