Streetlights are often kept on at full brightness throughout the night, even when roads and paths are empty. Some local governments are installing motion sensors on lights to change this pattern. The lamps remain dim when no movement is detected and become brighter when a pedestrian, bicycle, or vehicle approaches. After the person or vehicle passes, the lights return to a lower level.

Electricity is carried over long distances by transmission lines supported by tall towers. These lines must be checked regularly for broken parts, loose connections, or damage caused by storms. Traditionally, workers inspect them from the ground, climb towers, or use helicopters. Some power companies now send drones with cameras and other sensors along the lines to collect detailed images for later examination by engineers.

Most houses are built by workers who assemble wood, bricks, concrete, and other materials at a construction site. A newer method uses a large 3D printer.

Gene editing is a technology that changes selected parts of an organism's genetic information. Unlike genetic modification, it can alter particular characteristics without introducing genes from another species. Researchers are applying this method to crops and other foods in order to change features such as growth, shape, or nutritional content. Some gene-edited foods are already being developed for farming and commercial use.
