A friend sent me an email with the following World Challenge. I checked my calendar, I'm available, and have penned this event in.Can't hurt - right? and it's only 10 minutes - so what the heck, let's give it a try!
(I've altered the English translation just a bit for clarity)
APAGÓN MUNDIAL EL 17 DE SEPTIEMBRE DE 2008 ESTE APAGÓN SERÁ DE 21:50 A 22:00, A LA MISMA HORA LOCAL DE CADA PAÍS EN TODO EL MUNDO.
On Wendesday, September 17, 2008, I invite people around the world to turn off their lights for ten minutes – from 9:50pm to 10:00pm in their local time zone.
Oscuridad Mundial: En Septiembre 17, 2008 desde las 21:50 a las 22:00 horas. Se propone apagar todas las luces y si es posible todos los aparatos eléctricos, para que nuestro planeta pueda “respirar”. Si la respuesta es masiva, la energía que se ahorra puede ser brutal. Solo 10 minutos y vea que pasa. Si estamos 10 minutos en la oscuridad, prendamos una vela y simplemente la miramos y nosotros estaremos respirando y nuestro planeta. Recuerde que la unión hace la fuerza y el Internet puede tener mucho poder y puede ser aun algo más grande.
World Darkness: On September 17, 2008 from 21:50 to 22:00 hours. Proposal is to delete all lights and if possible all electrical appliances, 
so our planet can 'breathe'. If the response is massive, energy saving can be incredible. Only 10 minutes, and see what happens. Yes, we are 10 minutes in the dark, we light a candle and simply be looking at it, we breathe and so does our planet. Remember that in union is strength and the Internet can be very powerful tool.
