The first registers of Christmas celebration go back to 336 AC, when Catholic Church, instead of prohibiting pagan festivities, converted them into Christian ones. The origin of what we now know as Christmas was placed upon the Sol Invictus -- a bunch of gods that were taken as the supreme divinity of Roman Empire.
The ritual's partakers, celebrated at Winter's solstice, lighted candles to keep the divine presence alive. Centuries later, with electricity, the paraffin candles were firstly substituted by electric candles and, after that, for little lamps which are now available at retail markets during the end of the year. Despite what many people can think, there's connection with Menorah, the Jewish candelabrum.
The tail lights became popular thanks to their low cost and great visual at façades, gardens and Christmas trees. Taken as kitsch stuff for being the home version of the grandiose Christmas decorations of buildings, parks and public monuments, the micro-lamps invade the surroundings' residences of several Occidental cities, where competitions for the most illuminated house are very common.
Such energy and money waste may sound like controversial at the latest times -- a period when we live with marks of a global economic crisis and, besides, a period when we hear more-and-more a saving-resources-speech in order to save the planet.
And those budgetary problems turned off some lights during the last Christmas. Chichester's city hall, in South-East England, for instance, couldn't afford a high cost of energy during the celebrations. Highly esteeming the taxpayer, they cut any kind of decoration with public resources.
On the other hand, Christmas decoration isn't destined to repression: new technologies are becoming an available alternative when we talk about energy waste. LED (Light Emitting Diode), for example, consumes 8 times less than an incandescent lamp with the same power and last for 100 thousand hours -- it means, more than 10 years of ceaseless use. If they are turned on only on December, they can last for 120 Christmas celebrations.
