Small lasers have dimensions or modes sizes close to or smaller than the wavelength of emitted light. In recent years there has been significant progress towards reducing the size and improving the characteristics of these devices. This work has been led primarily by the innovative use of new materials and cavity designs. This Review summarizes some of the latest developments, particularly in metallic and plasmonic lasers, improvements in small dielectric lasers, and the emerging area of small bio-compatible or bio-derived lasers. We examine the different approaches employed to reduce size and how they result in significant differences in the final device, particularly between metal- and dielectric-cavity lasers. We also present potential applications for the various forms of small lasers, and indicate where further developments are required.

Lighting is a big consumer of electricity in industry, and it can account for 15-45% of total electricity consumption. LED lighting has become an increasingly popular choice, as it can reduce electricity used for lighting by up to 85%, while providing brighter illumination than most traditional lighting solutions. Electronic components account for the majority of the remaining electricity consumption in industry, as machines, computers, robots and other electronic devices often require a large amount of energy to operate, both directly and indirectly.

By monitoring the data provided by the electricity meter, energy efficiency managers and energy and environment managers can map the equipment that is consuming and the usage and then adapt their behavior accordingly to reduce consumption and cut energy costs.

Electricity metering is therefore an indispensable tool for responsible consumption and the adoption of clean technologies. It allows companies to save money by consuming less and to contribute to a more sustainable consumption by using renewable energies. This technology allows manufacturers to monitor their consumption, giving them better control over their bills and helping them to adopt more responsible consumption.

One effective way to do this is to implement staff awareness and training programs to accompany energy audits. Through this awareness and training, employees have the knowledge to identify key areas in their workplace where energy can be saved. Once these areas are identified, practices can be put in place to promote greater efficiency and conservation. These include using equipment properly, and implementing industrial automation processes that reduce facility operational costs while increasing overall productivity levels. With awareness and training initiatives in place, companies are able to take meaningful steps toward a greener future.

Eating is one of the most important electrical consumption items in the industrial sector. Many industries rely on heating processes to create a product, or maintain materials and tools at specific temperatures. These heating systems can consume significant amounts of electricity, especially if they are not properly insulated or maintained. Electric heating equipment used in factories and workshops generates significant electricity costs through heating and cooling equipment, heating bars or coils, water heating systems, and high-pressure boilers. Electrical heating also plays an important role in manufacturing and drying processes such as steel, for example in furnaces or ovens.
