In most materials, motion eventually fades. Electric current weakens as electrons scatter inside a wire. Heat spreads through a solid until temperature differences vanish. Fluids moving through pipes ...

As more and more solar and wind energy enters Australia’s grid, we will need ways to store it for later. We can store electricity in several different ways, from pumped hydroelectric systems to large ...

Energy transfer is systematically reviewed as a guiding principle for current materials and optimization strategies in perovskite solar cells. Characteristic mechanisms are identified to classify ...

A scientist in safety glasses, a blue lab coat, and gloves holds a measuring device and stands in front of a large cube fitted with polyvinyl chloride pipes and flexible tubes. At a facility in ...

An oil supertanker navigates crowded waters with tugboat assistance—an image of global energy in 2025: oversized, slow to turn and increasingly dependent on outside forces to stay afloat. NurPhoto via ...
