    Environmental heat sinks beyond local air are available for use with normal air conditioners to increase their efficiency. A study has exploited outer space and the atmosphere as remote sinks to demonstrate daytime sub-ambient fluid cooling and its application in reducing the energy needed to cool an interior.

    The Trump administration's domestic plans would have curtailed the nation's climate action even if it had stayed in the Paris Agreement. Yet, the decision to leave the agreement undermines US international energy and climate leadership and the prospects of ramping up global climate policy ambition.

    The structure of active sites of enzymes involved in bioenergetic processes can inspire design of active, stable and cost-effective catalysts for renewable-energy technologies. For these materials to reach maturity, the benefits of bioinspired systems must be combined with practical technological requirements.

    The utilization of porous carbon cathodes in lithium–air batteries is hindered by their severe decomposition during battery cycling. Now, dual redox mediators are shown to decouple the complex electrochemical reactions at the cathode, avoiding cathode passivation and decomposition.

    Transition-metal dichalcogenides are appealing catalysts for H2 generation from water. They tend to rely on scarce edge sites, rather than the more abundant basal-plane sites, to drive catalysis. Now, guided by computation, H-TaS2 and H-NbS2 are proposed as highly basal-plane-active catalysts that improve with electrochemical cycling.

    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.

    Wind turbines have been a go-to technology for addressing climate change, but they are increasingly a source of frustration for all stakeholders. While community ownership is often lauded as a panacea for maximizing turbine acceptance, a new study suggests that decision-making involvement — procedural fairness — matters most.

    The UN Sustainable Development Goal 7 aims to deliver affordable, reliable, sustainable and modern energy for all. Tracking progress towards the targets under this goal can spur better energy statistics and data gathering capacity, and will require new indicators that also consider the interplay with other goals.
