Energy models provide powerful insights for decision-makers, but more care is needed around the choice of reference scenarios and the transparency of assumptions.
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.
Recent large-scale carbon-capture schemes in the energy sector point to progress, but further development and support are still required to improve viability and widespread deployment.
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 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.
The development of rechargeable batteries looks hugely successful on paper, but moving in leaps takes fundamental breakthroughs, truly meaningful performance advances, and technological integration.
