Re: AzValor: Para los que estaban esperando su vuelta desde hace un año....
Respecto al debate de la sustitución del petróleo, hace poco he leído en un libro que la adopción masiva de la iluminación LED ha llevado más de 50 años desde su descubrimiento, a pesar de su eficiencia y de ser aparentemente mucho más sencillo que la sustitución del petróleo:
“It was back in 1962 that scientist Nick Holonyak, Jr., created the first practical visible light–emitting diode. At General Electric they called it “the magic one.” It took another half century to develop an LED house bulb, and even then, many US consumers revolted, preferring to slow the phase-out of incandescent bulbs even as other nations moved forward with the LED revolution. Eventually, a combination of tax incentives and laws that outlawed the Edison lightbulb forced the adoption of LED lighting. Today’s LED lights use 75 percent less energy than incandescent lighting and last fifty times as long, which in a typical home is about two decades. Widespread use of LEDs in the United States is set to save the equivalent of the annual output of forty-four large electric power plants, saving about $30 billion a year.”
