    In 2014 China proposed an ultra-low emissions policy for coal-fired power plants to reduce emissions. Using comprehensive nationwide stack emissions monitoring data, Tang et al. show reductions in excess of 60% for SO2, NOx and particulate matter emissions since 2014, even as power generation overall increased.

    Low bandgap tin–lead perovskites are crucial to making efficient all-perovskite tandem solar cells but have so far shown poor stability. By removing the hole transport layer and improving film morphology, Prasanna et al. demonstrate a low-gap perovskite solar cell that is stable for 1,000 h under heat, light and atmospheric conditions.

    Batteries generally do not perform well at extreme temperatures, and electrolytes are mainly to blame. Here, the authors dissolve fluorinated electrolytes in highly fluorinated non-polar solvents, enabling batteries that can operate at a wide temperature range (−125 to +70 °C).

    Improvements in the efficiency and stability of low-bandgap perovskite solar cells are key to enabling all-perovskite solar cells. Here, Lin et al. use metallic tin to prevent oxidation in such low-gap perovskite and demonstrate 24.8%-efficient tandems that are stable for over 400 h under operating conditions.

  • Policy Brief |

    Financing costs for renewable energy technologies have decreased substantially over the past 18 years, helping make renewables more cost competitive. Leveraging the effect of financial learning and continuing the policies that facilitated favourable financing conditions are key for greater renewable energy adoption in the future.

    Hotel guests changed their resource-use behaviour when they received feedback on their consumption in real time, even though they did not know that they were part of a study and had no financial incentives. Behavioural interventions provided by digital technologies are a scalable and cost-effective policy instrument for fostering resource conservation.
