Payments awarded for renewables are sometimes labelled as subsidies, suggesting support for uneconomic activity. This Perspective argues that the primary role of contracts for difference is risk management by creating a market for electricity supply at stable long-term prices.
The mechanical reliability of perovskite solar cells is a key hurdle that needs to be addressed to commercialize the technology. Dai and Padture discuss the driving stress, mechanical properties and mechanical failures relevant to these devices and how they should be characterized.
As the deployment of variable renewable energy sources may lead to greater cross-border electricity exchange, energy scholars have generally presumed the emergence of cooperative multi-state grid communities. This Perspective uses International Relations theory to explore this assumption.
Justice is increasingly recognized as a core proposition for energy transitions, but questions remain about how it manifests in energy transition innovations. This Perspective introduces a framework for centring justice consideration in these innovations across levels, illustrating its use through two case studies.
