The chemical process that breaks complex organic molecules into simple molecules. The term is used to identify a type of electricity-generating station or any energy output in which the main mover is driven by FLOWing water. The latter are the easiest to access and, therefore, the only forms being used commercially. Rocks whose origin is the cooling and solidification of magma, molten rock material. An incandescent bulb is the most common and least energy-efficient lamp.
Electricity runs through a tungsten filament that glows and produces a soft, warm light.
Because so much of the energy used is lost as heat, these are highly inefficient sources of light. Halogen lamps are a special, more energy efficient type of incandescent lamp containing halogen gas to produce a brighter, whiter light than incandescents. Having originated in and being produced, growing, living, or occurring naturally in a particular region or environment. The unchecked movement of outdoor air into a building through cracks around windows and doors or in walls, roofs, and floors.
