As renewable energy technology deployment continues apace, it is increasingly important to consider the optimal spatial allocation of power plants. Towards this end, Drechsler et al. employ a variety of methods to understand the most efficient and equitable distribution of solar and wind plants across Germany.
Electrical energy storage is expected to be important for decarbonizing personal transport and enabling highly renewable electricity systems. This study analyses data on 11 storage technologies, constructing experience curves to project future prices, and explores feasible timelines for their economic competitiveness.
Concentrating solar power with thermal storage offers dispatchable renewable power but has enjoyed less support than photovoltaics. This study of global concentrating solar power projects finds a learning rate of 20%, which should be sustained if policy support and industrial development continue.
This paper presents interrelated indicators for tracking progress towards the Paris Agreement. Findings show broad consistency with keeping warming below 2 °C, but technological advances are needed to achieve net-zero emissions.
Reforms of energy markets are necessary to face the low carbon transition but are problematic to measure. New data evaluate implicit taxes and subsidies for gasoline in almost all countries at monthly intervals showing mixed results that highlight the difficulty in implementing effective policy tools.
Biofuel prices depend on related commodities—such as corn, sugar cane and palm oil—but their connection to other non-feedstock commodities is less well explored. Filip et al. analyse a data set of 33 commodities and assets and examine their relationships to biofuels in Brazil, the US and Europe.
Typically, the allocation of renewable power sources is determined by a desire to maximize output and reduce generation costs in order to satisfy the preferences of a small number of stakeholders. A new model broadens this perspective by considering societal equity and acceptability, with the aim of improving the siting process.
