The population of world has exploded in the last few decades. In the early twentieth century, only manufacturing and construction units required energy on large scale. The energy needs of private users were low by comparison. Over time, however, the standard of living improved and household energy demand began to rise.
This demand was met by new energy sources and new mediums of generating electricity entered the picture. Hydroelectricity, using the power of falling water, came first and was joined by nuclear power. More recently, solar, wind, and tidal energy have begun to contribute.
The question now becomes exactly how much longer the energy demand-supply equation can remain in a balanced state. This has implications for public health and well-being and for national economies.
One smart approach toward conserving resources is to minimize consumption.
Today we have numerous lighting options. Incandescent lighting is giving way to the more efficient compact flourescents, and LED lighting is now entering the market. Quantum dot lighting is around the corner and may eventually supplant the LEDs, but for now it’s still in research and not yet available.
LED lighting for instrumentation, electronic equipment, and even handheld flashlights is popular around the world, but it has not yet made major market entry for screw-in replacement of home incandescent bulbs.
