It's cleaner and more efficient than alternatives
Electric lights are cleaner and more efficient than alternatives like candles, gas lights, oil lamps, and fires. They produce light from electricity, making them the most common form of artificial lighting. The energy efficiency of electric lighting has significantly improved since the first demonstrations of arc lamps and incandescent light bulbs in the 19th century.
Incandescent lamps, one of the three main categories of electric lights, produce light by passing an electric current through a filament, heating it to a white heat and causing it to glow. While traditional incandescent bulbs are highly inefficient, with only 2-5% of the energy consumed emitted as visible, usable light, modern halogen bulbs offer improved energy efficiency. In 1904, European inventors developed the tungsten filament, which produced a brighter light and lasted longer than carbon filament bulbs.
Fluorescent lighting is another option that offers improved energy efficiency over incandescent bulbs. These lamps use mercury vapour or argon gas under low pressure, with electricity flowing through the tube causing the gases to give off ultraviolet energy. While fluorescent lamps are more costly upfront due to the need for a ballast, their lower energy costs can offset this initial expense. However, the presence of mercury in these bulbs has led to concerns about their safe disposal, with many being classified as hazardous waste.
Light-emitting diodes (LEDs), a type of solid-state lighting, are among the fastest-developing lighting technologies today. LEDs are highly efficient, converting electricity into light through a semiconductor. They emit light in a specific direction, reducing the need for reflectors and diffusers. LEDs have higher luminous efficacy than incandescent bulbs, requiring less power to produce the same amount of light. This makes them a popular choice for energy-saving alternatives in homes.
