Earth Hour 2011

The criticisms of Earth Hour include:
• In March 2010, the Telegraph quoted electricity experts that "it could therefore result in an increase in carbon emissions" due to complications related to rapidly lowering then raising electricity generation.
• In February 2010, Rick Giles, president of ACT on Campus, the youth wing of New Zealand's ACT Party, appeared on the morning television show Sunrise to denounce Earth Hour and instead suggested the celebration of "Edison Hour". He argued that Earth Hour is an "anti-technology" cause, and that people will simply use candles instead, which is undesirable as they are petroleum-based. He argued that if we are heading for some kind of disaster, it makes sense to use technology to combat this. Rick quickly gained notoriety for saying "I think my argument is so powerful that it's not necessary to talk about it".
• The Christian Science Monitor said that most candles are made from paraffin, a heavy hydrocarbon derived from crude oil, a fossil fuel, and that depending on how many candles a person burns (if one uses candles during Earth Hour), whether or not they normally use compact fluorescent light bulbs, and what source of energy is used to produce their electricity, in some cases, replacing light bulbs with candles will cause an increase, instead of a decrease, in carbon dioxide emissions.
