One way to evaluate if the Earth Hour in the Philippines is successful or not is to compare the megawatt (MW) demand on March 21, 2009 and March 28, 2009. The Earth Hour was on March 28 at the time of 8:30 pm to 9:30 pm. We choose March 21 since this day is another Saturday which is the same as March 28.
Inquirer reports that RP shone in dim during that hour. Philippine Star wrote that RP had record power savings during the event.
The facts say otherwise. The graph below describes the demand in Luzon and Visayas regions for March 21 and 28, 2009. The data were taken from
Wholesale Electricity Spot Market (WESM) website. Comparing the demand curve of March 21 and 28 during the Earth Hour, we observed that there was more power utilization on March 28 than March 21. I am not sure where Inquirer and Philippine Star got their data.
