On March 28, if the lights go off in your Cape Town hotel or, close to home, a Seattle hotel restaurant switches to candles, do not be alarmed. It's not an electrical-grid meltdown but a global show of support.Our power grids are fairly delicately balanced. Having a significant load suddenly drop off at 8:30 and then just as suddenly come back on at 9:30 can create a bit of havoc for the equipment and people who have to manage the electrons.
During Earth Hour, citizens of the world are asked to turn off their power for one hour, starting at 8:30 p.m. local time, in a symbolic stance against global warming.
Consequently, to balance this problem out in my neighborhood, I plan to turn on every light in my house from 8:30 to 9:30 that night. Just doing my part to save the electric grid.
