Earth Hour: Vote for Sustainability by Turning Off the Lights

After the American Century

This year Earth Hour is on Saturday, March 26. Around the world millions of people will join this event and cut back their electrical consumption. This is a fundamentally new use of the technology of electricity, as people declare  that excessive energy use threatens the environment.

Less than a century ago most of the world's houses, and most in the US as well, did not have electricity. A blackout was inconceivable, as most people controlled their own light, in the form of lamps, candles, hearth fires, and the like. Between 1911 and 2011 a tremendous change has taken place. Not only have billions of people wired their houses and apartments, but the electrical systems have been connected together into vast grids. These are in many ways admirable, ingenious engineering feats, designed to shunt power around to balance the load at each local utility.  

But the interconnections that make possible the grid also make possible cascading system failures, spreading blackouts from one city and state to another. The most spectacular examples in the United States occurred in 1965 and 2003, when blackouts spread at almost the speed of lightning and pushed millions of people from the power dependency of the electrical age back to an involuntary self-sufficiency. With each generation we are less able to fend for ourselves, as more and more parts of our lives are inextricably linked to the electrical system. When the power fails, there is no Internet, no television, no microwave, and no air conditioning. The ATM does not work, mobile phones are suddenly dead, and the kitchens dark and useless, unless one has a gas stove. Even so, all the food begins to thaw in the freezer.

Earth Hour reminds us how to live without the power, however briefly, but it is far more than that. It also is each person's chance to use the electrical system as a voting machine. Turn off the appliances, switch off the lights, and tell politicians and fellow citizens that you want to pollute less and be more efficient. Join Earth Hour as a declaration that the endless growth in electrical consumption has to stop somewhere.

Did you know that the average American family today uses as much energy every month as their grandparents did in an entire year? Did you know that electrical consumption for the US as a whole doubled roughly every decade for most of the twentieth century? That kind of growth is not sustainable, nor is it necessary to live a good life. Turn off the lights. Rediscover conversation. With luck, after an hour you might be telling stories. Shut off the TV, look up, and see the stars.

Danish Awareness of "Earth Hour" Dim

After the American Century

Across the world, in 88 countries, cities turned out their lights last night for one hour, starting at 20:30 local time. The Houses of Parliament and Big Ben, dark. The Eiffel Tower? Noir. The Chinese Olympic stadium, Sydney's harbor bridge and opera house, Atlanta's Coca Cola Building, dark. Toronto reduced its total electricity consumption by 15% during "Earth Hour," more than twice as much as last year. It may have been the biggest global demonstration in history.

In most of the participating 2800 cities and towns, the local newspapers and politicians were actively promoting Earth Hour. However, I looked in vain for anything about Earth Hour II in two Danish newspapers this morning. Last night, the City of Odense turned out its streetlights at 20:30, as we did at our house. Yet, as I walked around our neighborhood, few others seemed to have done so. Using the simple test of looking for lighted candles showing in windows, it appeared that most people had lots of light bulbs on, and that perhaps one in ten actively supported "Earth Hour." I hope I am estimating incorrectly, but in the last week I have not sensed any awareness of this event. Not a single student, colleague, or neighbor has mentioned Earth Hour to me, or showed any interest in it when I mentioned it. Not one journalist has called or written an email asking for my view of Earth Hour, from the viewpoint of an energy historian.

This morning, the local newspaper (Fyens Stiftstidende) has not written a single word about "Earth Hour" that I can find. The front page features a photograph of two girls eating ice cream. The three stories on page one are about increasing service charges on house loans, Conservative tactics for the next (hypothetical) election, and an extremely important piece on the development of a cardboard, biodegradable "Paradise coffin" for pets, available in five sizes. On the plus side, the same newspaper has five pages about energy-saving forms of electric lighting in its second section, without, however, mentioning Earth Hour anywhere that I can see.

Apparently, for all-too-many Danes, global warming is only an issue of concern for thousands of cities in other parts of the world. Judging by this event, you would never know that Denmark is hosting a major climate conference that will seek a replacement for the Kyoto Accords. Political parties paid lip service to the event, but except for a single concert in Copenhagen, the event was a non-event in Denmark. For 2009, the clear message from Denmark seems to be that hardly anyone cares very much about Earth Hour or about forging a world consensus to reduce global warming. To anyone familiar with the current government, this should come as no surprise. Maybe next year they will use their wall switches to vote for change, to proclaim the solidarity with others, and to send their politicians a message.

Why You Should Turn Off the Lights Tonight

After the American Century


Turn off the lights for one hour, tonight. Why?

(1) Because this is a way for people all over the world to demonstrate, quite painlessly, that we are concerned about global warming and the over-intensive use of fossil fuels.

(2) Because all of us can use less energy every day, without sacrificing anything, and we need to remember that we are not passive spectators, watching global warming. We are actors. We can make a difference, if we act together. In 1997, the average home in the OECD countries used 38 watts every day just to keep appliances on standby. These 386 million households were wasting 14,634 megawatts a day. Does anyone think this waste is necessary? Of course not. But we need to make an effort.

(3) Because the electrified world is historically new, and once in a while we need to remember what darkness looks like. Human beings evolved without artificial light, and during this hour we might reflect on where we stand in relation to the more than 100,000 years of human history. Human beings have used electricity for light and power for less than one tenth of one percent of human history. In that blink of an eye, historically speaking, we have polluted the atmosphere and the sea and unbalanced ecological systems in ways that we are struggling to understand.

(4) Because your house and your family seen by candlelight are beautiful in ways that you may not have seen lately. The human eye did not evolve to see the world blanketed in electric light, but rather evolved to see somewhat differently by day and by night.

(5) Because if the sky is clear, you will get a good look at the heavens. The urban landscape especially can be improved by reducing electric light. Most urbanites scarcely see the heavens at night, because excessive artificial light reflects into the atmosphere, making it impossible to see more than the brightest stars.

So why let this night be like all the others? Why not turn out the lights, and look for a local arrangement celebrating "Earth Hour" as it is called in many places, following the Australians who began this ritual in Sydney. The Danes are calling it something else, and starting not on the hour but at 20:30.

As the Toronto Star put it last year, “This event is an opportunity to show how individuals acting together as a community can have a huge impact. Ultimately, we hope it gets people thinking and talking here in Toronto and in cities around the world about real solutions to what is arguably the most important issue of our time.”
