The Bangkok Post gave different figures of 165 megawatt hours and 102 tons of carbon dioxide. This is a year ago, when 530 megawatt-hours were saved and 143 tons of carbon dioxide emission were cut. Philippine Electricity Market Corp. noted 78.63 megawatts in Metro Manila, and up to 102.2 megawatts on Luzon. The maximum demand drop of around 39 MW was at 8:14 pm in Metro Manila and around 116 MW at 8:34 pm in the Luzon grid. Ontario used approximately 900 megawatt-hours less electrical energy during Earth Hour. At one point, Toronto saw an average Saturday night. Ireland, as a whole, about 1.5% for the evening.

Bjørn Lomborg, author of The Skeptical Environmentalist, wrote, “It is vital to make solar and other technologies cheaper than fossil fuels quickly so we can turn off carbon energy. Fossil fuels literally gave us an enlightenment, by lighting our world and giving us protection from the fury of the elements. Lomborg also pointed out the feel-good factor Earth Hour creates, noting that it is an “ineffective feel good event” that makes people feel they are doing something for the environment, while in reality the amount of carbon emissions is reduced by the earth hour is negligible. Other criticisms of the Earth Hour have included the following:
