Musings: Energized

The pre-dawn light was slow in arriving this cloudy morning, so I was expecting a minimalist sunrise. But once again I was reminded not to underestimate nature, for as Koko and I dodged puddles on a very wet road, the somber sky shifted into a kaleidoscope of gold, blue, white, red, orange, gray and pink.

While most of the action was in the northeast, clouds halfway across the sky turned an almost translucent red, snuggled up against patches of baby blue flecked with dots of white that were devoured by swirling masses of gray. And the shapes and colors shifted constantly, because way up there in their world, the wind was blowing and everything was on the move.

I’ve been thinking about the power of wind after reading an excellent New Yorker article by Elizabeth Kolbert on a Danish island that has managed, in a decade, to reach a point where it is producing more energy from renewable sources than it uses. Much of that power comes from wind turbines, which aren’t pretty. But then, neither are the oil spills, refineries, shale oil mining pits and Middle Eastern battlefields that are the backstory of our fossil fuel addiction.

What I liked best about the story was the revelation that the island’s 4,300 inhabitants aren’t greenies, or folks out to save the world. They just made a conscious choice to change the source of their energy — without government assistance and special tax breaks. As Kolbert writes:

The residents of Samsø that I spoke to were clearly proud of their accomplishment. All the same, they insisted on their ordinariness. They were, they noted, not wealthy, nor were they especially well educated or idealistic. They weren’t even terribly adventuresome. “We are a conservative farming community” is how one Samsinger put it. “We are only normal people,” [Jørgen] Tranberg told me. “We are not some special people.”

That got me thinking. Even though we on Kauai like to think of our island — and ourselves, by extension — as special, we are also ordinary people. And we have tremendous opportunities for solar, wind, wave and biomass available to us. Could it be possible for us to achieve energy independence, too?

Of course, it would require some major adjustments, not just in how we generate energy, but how we power our economy, too. I’m not quite sure how the fuel-sucking tourism industry, with its helicopters, boats, rental cars and abundant AC — and the jets that ferry folks from all parts of the world — would factor into the equation, or the military, with its missile launches and war games and plans for giant lasers that gorge on electricity.

But maybe these wasteful pursuits are the kinds of things we need to be examining closely, anyway, in the overall scheme of things.

As Kolbert notes in her article, a group of Swiss scientists has determined that 2,000 watts per person is the level of sustainable energy use for the world. And that includes everything, from food to electricity to transportation. To put that in perspective, the U.S. and Canada are 12,000-watt societies, and much of that energy is wasted. As Kolbert writes:

Relying on widely agreed-upon figures, the [Swiss] scientists estimated that two-thirds of all the primary energy consumed in the world today is wasted, mostly in the form of heat that nobody wants or uses.

Upon reading that, I recalled visiting my sister in New Zealand many years ago. When she wanted hot water, she built a small fire of wood, scrap paper and cardboard in a burner beneath the tank, and we bathed, did dishes and washed clothes while the water was hot. We weren’t deprived of the luxury of hot water, but since we lacked the convenience of getting it on demand, we had to become more conscious of and efficient in our actions. And always, at least in my opinion, becoming more conscious of our actions is a desirable thing.

Interestingly, the people of Samsø didn’t cut their energy use. It seems that when their homes were better insulated, they simply heated more rooms. All of us in the Western world have learned to take energy, and the comforts it brings, for granted, but that doesn’t mean we can’t learn new tricks. The question, of course, is whether we can bothered to change our ways.

Perhaps, as energy prices rise and we’re confronted with more and more evidence of global warming and its unpleasant consequences, we’ll be motivated. I don’t think we’re there yet, but perhaps isolated islands fully dependent on imported oil are good places to start.

In her article, Kolbert asked Søren Hermansen, one of the movers and shakers behind the Samsø conversion, what other communities might take from their experience:

“We always hear that we should think globally and act locally,” he said. “I understand what that means—I think we as a nation should be part of the global consciousness. But each individual cannot be part of that. So ‘Think locally, act locally’ is the key message for us.”

And with that, I'm going to shut off the breaker to my hot water heater and use what's already heated for the rest of the day.

Better still, put a timer on the hot water heater, which is very common. It provides electricity to the hot water heater, for example, 2 hrs in the day and 2 hrs at night. That doesn't mean the electricity is used, but that it becomes available.

Even better, go to an electric tankless on-demand hot water system like we have (gas not an option). You don't waste electricity heating a tank of water in "standby" for when needed. You don't heat to 120 degrees either.

You use juice only when a hot water tap is turned on. A 10-position switch allows different heat temps to be chosen.

Ours saved us at least $60/mo.

Building a wood fire every time you want hot water??

That's a little too much "little house on the prarie" for me. I don't mind the "little house" thing, as long as it has all the conveniences, incl sat tv and dsl.

El Hierro in the Canary islands is another island that hopes to go 100% renewable, at least for electricity. They have about 10,000 inhabitants, and will use a wind farm to generate electricity and reservoirs to store energy (excess electricity is used to pump water uphill).

Great idea, but you've got to have or build reservoirs. I know some mainland company wants to build a reservoir above Wailua Falls to generate power, but why don't they use Alexander reservoir, which is already fairly high in altitude.

Then there's the whole issue of where to put the wind farm. I've seen maps that show the Kalihi ridge, above the Kahili mountain park and adventist school is a good place--I wonder if the community would go for that. Personally, I think the coast between Kealia and Anahola, facing the trade winds would be perfect.

For Hawaii, waves are probably a better deal, or the ocean thermal thingy. I spoke to a number of people on an island in Scotland that has had a wave generator running for years. No one pays attention to it anymore, it's no longer even a tourist attraction. There are several types.

But we are sheep without fleece, we are led around by the noses by power companies and their bought politicians who tell us how we may keep warm. Hawaii should have been using alternative energy all along. Now a crisis is looming, and guess what, we'll still let the power companies lead us by the noses.

Neither the Danish islanders nor the Scotland folks are sheep.

By the way, the flash heaters recommended in the comments are used the world over. It's just Americans who persist with wasteful tank-type water heaters as far as I know.

Yeah, it's kinda scary how resistant we are to large-scale changes. Yet we're at a precipace and we better do something quick.

Unfortunately, individualism makes it difficult to engage in collective solutions, which is exactly what's needed.

But I think the more we hear about sucesses around the world the more folks will begin to accept that these changes are possible.

Oil dropped to "only" $119.55 a barrel!

If you travel up river on just about every stream on Kaua`i you will get to a dam- sometimes many of them- all from the old sugar cane days. They were built to feed irrigation ditches and the ditches themselves can be tapped easily... and cheaply... and without any further disruption of stream flow. They are already built- just waiting for modification to pull power,.
