"Casi 14000 kWh por habitante y día" es el equivalente a tener encendidas muchas bombillas de 100 watios durante 24 horas.<BR/><BR/>Una bombilla de 100 watios x 24 horas son 2.400 watios-hora, o 2'4 kWh.<BR/><BR/>14.000 kWh / 2'4 kWh = del orden de 6.000 veces más. No un 6% más, ni un 60% más, ni 6 veces más. 6 mil veces más.<BR/><BR/>Algo está mal en las cifras.<BR/><BR/>Tienes que contrastarlo por otro lado.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9676390.post-36082419248573624482008-07-25T11:11:00.000+01:002008-07-25T11:11:00.000+01:00http://www.newyorker.com/reporting/2008/07/07/0807...http://www.newyorker.com/reporting/2008/07/07/080707fa_fact_kolbert?currentPage=all<BR/><BR/>Del artículo al que hace referencia gmoke: "One way to think about the 2,000-Watt Society is in terms of light bulbs. Let’s say you turn on twenty lamps, each with a hundred-watt bulb. Together, the lamps will draw two thousand watts of power. Left on for a day, they will consume forty-eight kilowatt-hours of energy; left on for a year, they will consume seventeen thousand five hundred and twenty kilowatt-hours. A person living a two-thousand-watt life would consume in all his activities—working, eating, travelling—the same amount of energy as those twenty bulbs, or seventeen thousand five hundred and twenty kilowatt-hours annually.<BR/><BR/>Most of the people in the world today consume far less than this. The average Bangladeshi, for example, uses only about twenty-six hundred kilowatt-hours a year—this figure includes all forms of energy, from electricity to transportation fuel—which is the equivalent of using roughly three hundred watts continuously. The average Indian uses about eighty-seven hundred kilowatt-hours a year, making India a one-thousand-watt society, while the average Chinese uses about thirteen thousand kilowatt-hours a year, making China a fifteen-hundred-watt society.<BR/><BR/> * from the issue<BR/> * cartoon bank<BR/> * e-mail this<BR/><BR/>Those of us who live in the industrialized world, by contrast, consume far more than two thousand watts. Switzerland, for instance, is a five-thousand-watt society. Most other Western European countries are six-thousand-watt societies; the United States and Canada run at twelve thousand watts. One of the founding principles of the 2,000-Watt Society is that this disparity is in itself unsustainable. “It’s a basic matter of fairness” is how Stulz put it to me. But increasing energy use in developing countries to match that of industrialized nations would be unacceptable on ecological grounds. Were per-capita demand in the developing world to reach current European levels, global energy consumption would more than double, and were it to rise to the American level, global energy consumption would more than triple. The 2,000-Watt Society gives industrialized countries a target for cutting energy use at the same time that it sets a limit for growth in developing nations.<BR/><BR/>The last time Switzerland was a two-thousand-watt society was in the early nineteen-sixties. By the end of that decade, energy use had reached three thousand watts, and by the mid-seventies it was up to four thousand watts. This rapid rise could be said to follow from technological advances—the spread of automobiles, the advent of jet travel, the proliferation of appliances and electronic devices—or it could be seen as just the reverse: a failure to apply technology where it is needed. A few years ago, a group of Swiss scientists published a white paper—or, to use the Swiss term, a “white book”—on the feasibility of a 2,000-Watt Society. Relying on widely agreed-upon figures, the scientists estimated that two-thirds of all the primary energy consumed in the world today is wasted, mostly in the form of heat that nobody wants or uses. (“Primary energy” is the energy contained in, say, a lump of coal; “useful energy” is the light emitted by a bulb once that coal has been burned to produce steam, the steam has been used to run a turbine, and the resulting electricity has been transmitted over the grid to heat the bulb’s filament.) This same paper concluded that, with currently available technologies, buildings could be made eighty per cent more efficient, cars fifty per cent more efficient, and motors twenty-five per cent more efficient."<BR/><BR/>"Very broadly speaking, the average Swiss today uses energy as follows: fifteen hundred watts per day for living and office space (this includes heat and hot water), eleven hundred watts for food and consumer items (the energy that it takes to produce and transport goods is referred to as “embodied” or “gray” energy), six hundred watts for electricity, five hundred watts for automobile travel, two hundred and fifty watts for air travel, and a hundred and fifty watts for public transportation. Each person’s share of Switzerland’s public infrastructure, which includes facilities like water- and sewage-treatment plants, comes to nine hundred watts. Reducing these five thousand watts to two thousand would seem to require a significant reduction in every realm. Assuming that infrastructure-related consumption could be cut to five hundred watts, a person who continued to use fifteen hundred watts for living and office space would have nothing left for food, electricity, and transportation. Similarly, a person who continued to travel and use electricity at current rates would consume two thousand watts without having anywhere to live or work, or anything to eat."Anonymousnoreply@blogger.com
