Earth Hour: Is It Worth It?

Earth Hour, one hour a year when people are encouraged to turn off all lights and appliances in an effort to reduce carbon dioxide, is not worth says one conservationist:

The organizers say that they are providing a way to demonstrate one’s desire to “do something” about global warming. But the reality is that Earth Hour teaches all the wrong lessens, and it actually increases CO₂ emissions. Its vain symbolism reveals exactly what is wrong with today’s feel-good environmentalism.

Earth Hour teaches us that tackling global warming is easy. Yet, by switching off the lights, all we are doing is making it harder to see.

Notice that you have not been asked to switch off anything really inconvenient, like your heating or air-conditioning, television, computer, mobile phone, or any of the myriad technologies that depend on affordable, plentiful energy electricity and make modern life possible. If switching off the lights for one hour per year really were beneficial, why would we not do it for the other 8,759?

Hypothetically, switching off the lights for an hour would cut CO₂ emissions from power plants around the world. But, even if everyone in the entire world cut all residential lighting, and this translated entirely into CO₂ reduction, it would be the equivalent of China pausing its CO₂ emissions for less than four minutes. In fact, Earth Hour will cause emissions to increase.

As the United Kingdom’s National Grid operators have found, a small decline in electricity consumption does not translate into less energy being pumped into the grid, and therefore will not reduce emissions. Moreover, during Earth Hour, any significant drop in electricity demand will entail a reduction in CO₂ emissions during the hour, but it will be offset by the surge from firing up coal or gas stations to restore electricity supplies afterward.

And the cozy candles that many participants will light, which seem so natural and environmentally friendly, are still fossil fuels—and almost 100 times less efficient than incandescent light bulbs. Using one candle for each switched-off bulb cancels out even the theoretical CO₂ reduction; using two candles means that you emit more CO₂.

Electricity has given humanity huge benefits. Almost 3 billion people still burn dung, twigs, and other traditional fuels indoors to cook and keep warm, generating noxious fumes that kill an estimated 2 million people each year, mostly women and children. Likewise, just 100 years ago, the average American family spent six hours each week during cold months shoveling six tons of coal into the furnace (not to mention cleaning the coal dust from carpets, furniture, curtains, and bedclothes). In the developed world today, electric stoves and heaters have banished indoor air pollution.

Similarly, electricity has allowed us to mechanize much of our world, ending most backbreaking work. The washing machine liberated women from spending endless hours carrying water and beating clothing on scrub boards. The refrigerator made it possible for almost everyone to eat more fruits and vegetables, and to stop eating rotten food, which is the main reason why the most prevalent cancer for men in the United States in 1930, stomach cancer, is the least prevalent now.

Electricity has allowed us to irrigate fields and synthesize fertilizer from air. The light that it powers has enabled us to have active, productive lives past sunset. The electricity that people in rich countries consume is, on average, equivalent to the energy of 56 servants helping them. Even people in Sub-Saharan Africa have electricity equivalent to about three servants. They need more of it, not less.

If environmentalists were truly concerned, they would forgo meaningless gestures and address the real problems facing the natural environment and they would certainly not restrict life-saving and changing inventions that better the lives of others, not restrict or end them. As it stands, Earth Hour is a display and nothing more.
