The Impact

Electricity generation requires water. With the global demand for electricity expected to increase significantly in the coming decades, the water demand in the power sector is also expected to rise. However, due to the ongoing global energy transition, the future structure of the power supply—and hence future water demand for power generation—is subject to high levels of uncertainty, because the volume of water required for electricity generation varies significantly depending on both the generation technology and the cooling system. This study shows the implications of ambitious decarbonization strategies for the direct water demand for electricity generation. To this end, water demand scenarios for the electricity sector are developed based on selected global energy scenario studies to systematically analyze the impact up to 2040. The results show that different decarbonization strategies for the electricity sector can lead to a huge variation in water needs. Reducing greenhouse gas emissions (GHG) does not necessarily lead to a reduction in water demand. These findings emphasize the need to take into account not only GHG emission reductions, but also such aspects as water requirements of future energy systems, both at the regional and global levels, in order to achieve a sustainable energy transition.

Pv Power Generation

The deployment of solar photovoltaics (PV) and electric vehicles (EVs) is continuously increasing during urban energy transition. With the increasing deployment of energy storage, the development of the energy sharing concept and the associated advanced controls, the conventional solar mobility model (i.e., solar-to-vehicles (S2V), using solar energy in a different location) and context are becoming less compatible and limited for future scenarios. For instance, energy sharing within a building cluster enables buildings to share surplus PV power generation with other buildings of insufficient PV power generation, thereby improving the overall PV power utilization and reducing the grid power dependence. However, such energy sharing techniques are not considered in the conventional solar mobility models, which limits the potential for performance improvements. Therefore, this study conducts a systematic review of solar mobility-related studies as well as the newly developed energy concepts and techniques. Based on the review, this study extends the conventional solar mobility scope from S2V to solar-to-buildings, vehicles and storage (S2BVS). A detailed modeling of each sub-system in the S2BVS model and related advanced controls are presented, and the research gaps that need future investigation for promoting solar mobility are identified. The aim is to provide an up-to-date review of the existing studies related to solar mobility to decision makers, so as to help enhance solar power utilization, reduce buildings’ and EVs’ dependence and impacts on the power grid, as well as carbon emissions.

Damage Costs

Abstract The German Energiewende (energy transition) started with price guarantees for avoidance activities and later turned to premiums and tenders. Dynamic efficiency was a core concept of this environmental policy. Out of multiple technologies wind and solar power—which were considered too expensive at the time—turned out to be cheaper than the use of oil, coal, gas or nuclear energy for power generation, even without considering externalities. The German minimum price policy opened doors in a competitive way, creating millions of new generators and increasing the number of market participants in the power sector. The fact that these new generators are distributed, non-synchronous and weather-dependent has caused contentious discussions and specific challenges. This paper discusses these aspects in detail and outlines its impacts. It also describes Swiss regulations that successfully launched avoidance technologies or services and asks why exactly Pigou's neoclassical economic approach to the internalization of damage costs (externalities) has rarely worked in policy reality, while sector-specific innovations based on small surcharges have been more successful. Based on the model of feed-in tariffs, a concept for the introduction of low-carbon air traffic is briefly outlined. Graphic Abstract

The Uk

Community energy (CE) and grassroots innovations have been widely studied in recent years, especially in the UK, Germany, and the Netherlands, but very little focus has been placed on Sweden. This paper describes and analyses the development and present state of several types of community energy initiatives in Sweden. The methodology uses interviews, document studies, analysis of previous studies, and website analysis. The results show that fewer initiatives have been taken in Sweden than in other countries, but that even with a rather ‘hostile’ institutional setting CE has emerged as a phenomenon. Wind cooperatives are the most common form of initiative, with solar photovoltaics cooperatives and eco-villages also prominent. The various types of initiatives differ considerably, from well-organized wind cooperatives that have grown into professional organizations to small-scale hydroelectric power plants owned by a rural community. The initiatives may have modest impact on the energy transition in quantitative terms, but they are crucial in knowledge sharing and as inspirations for future initiatives.
