    Solid-state caloric cooling is a promising alternative to vapour-compression refrigeration yet practical devices are not sufficiently efficient for applications. Meng et al. combine cascade device design with charge recovery and improve the cooling efficiency and temperature lift of an electrocaloric device.

    Metal–organic frameworks (MOFs) are increasingly being explored for electrocatalytic oxygen evolution, which is half of the water splitting reaction. Here the authors show that, under reaction conditions, mixed metal oxyhydroxides form at the nodes of bimetallic MOFs, which are highly catalytically active.

    The appropriate descriptors for a catalyst’s hydrogen evolution activity in alkaline electrolyte are debated. Combining simulations and single-crystal studies of metal-decorated Pt surfaces, McCrum and Koper show that activity exhibits a volcano-type relationship with the hydroxide binding strength of the catalyst, providing a target for catalyst design.

    Estimating the costs of green home improvements is not possible without accurate estimates of their impact on house prices. Now, Shen et al. use the sales data of more than 400,000 properties in the United States to determine how heat pump installations increase house prices.

    Low-bandgap tin–lead perovskites are key to all-perovskite tandem solar cells but simultaneous improvement in efficiency and stability has proven challenging. Now, Li et al. fabricate tin–lead perovskite cells with reduced methylammonium content that are 20.4% efficient and stable under illumination for 450 h.

    The design of research solar cells is typically optimized for laboratory conditions but in the real world they are exposed to changing temperatures influencing their performance. Now, research from outdoor tests reveals how temperature alters the current of perovskite/silicon tandem solar cells and how this changes the optimal bandgaps.

    Current collectors are essential components in lithium-ion batteries, but are typically made of metal foils that do not contribute to the battery capacity. Now, a fire-extinguishing lightweight polymer-based current collector is developed that enhances both the energy density and safety of the battery.

    Government programmes such as the Advanced Research Projects Agency-Energy (ARPA-E) are designed to help cleantech companies overcome startup challenges and bring innovations to market. New analysis shows that support from ARPA-E has led to higher patenting rates but success in winning follow-up funding remains unclear.

Social Dynamics of Energy Behaviour

Energy use occurs in homes, workplaces and communities in which complex webs of social relations already exist, and social interactions routinely occur.
