Danish Goal: 50% of Electricity from Wind
tres3 writes "The Danes have an ambitious
plan of producing 50% of their national electrical needs from wind by 2030. The website has tutorials on everything related to wind energy you can imagine. The index gives you an idea of the detail of the site. It includes land and sea wind turbines as well as details about the machinery needed and where to locate it. There are over 100 pages so I didn't link to them all. [ed. note: thanks] A picture says it all."
They are also pretty loud as well. Wildlife also is pretty picky about living anywhere in the vacinity of items that produce noise.
Sure. Tell me more. You have some information or statistics that involve modern windmill technology?
You're familiar with modern wind technology, correct? Large blades, turning slowly. Certainly some birds might smack into them (the same way they do to buildings and cars), but we're not talking about the little, fast-moving windmills of the 1970s and 80s.
I'm tired of hearing this one trotted out every time somebody talks about wind. Show me the numbers, dammit!
They're certainly going to pollute the visual enviroment
Maybe we can disguise them as trees. Or put Budwiser advertising on them. Then they'll fit right in with the rest of the country :)
This is nice. They are in fact implementing known technology for the benefit of all, AND DOING SO IN an aggressive visionary project. It is unfortunate that most of the industrialized world is not as nimble in implementing technology, when the benifits don't neccessarily fit neatly in an accountant's bookkeeping. We admire ourselves as humans with descriptions such as adaptive, modular etc. But our culture is not, when it comes in conflict with immediate rewards like profit. This Danish wind power project is an example of human culture rising to the challenge and becoming, indeed, an adaptive and modular culture. Now if we just had an aggressive program for developing cheap, clean and abundant energy.
A Good Troll is better than a Bad Human.
By having a focus, Danish industry can seek to acquire the IP such as patents to build up a top industry. As in other industries the idea is to go so far down the learning curve that it becomes more economical for other countries to buy the technology from you rather than develop it themselves.
That is why conservatives who bash alternative energy are stupid. Any reading of US history shows massive government involvement to nurture any industry whether through protective tariffs, cash for infrastructure, land grants, whatever. To make money you have to spend money. A so-called conservative who espouses capitalism should understand that.
I think the subject says it all. While impacting native wildlife is a differnet issue, if it was simply staring at white towers vs. not being able to breathe, I know what *i'd* choose...
- TV setup. My television, amplifier, and Tivo alone took up
1.6 Amps = 185 watts, while they were completely idle. The Tivo was not
recording anything, and I verified that it was not doing anything by
telnetting in and observing that the load average was 0.00. Does it
really require 1.6 amps just to spin a hard drive and wait for a
10mW infrared signal??
- Computer monitors. I run XFree86 4 in dual-head mode. My two
monitors take up 2.6 Amps = 300 watts while they are on, and a whopping 70
watts when they are turned off at the switch. It's worth noting that they
produce about a third of the light, and twice the heat, of two 150W light
bulbs.
- Computer hardware. The power strip supporting my 1.6Ghz Athlon
and 1Ghz Duron draws a whopping 4.4 Amps, or 500 watts, while
both systems sit at zero load! Apparently, AMD expended significantly
more effort making sure their processors were well-equipped to start house
fires when the heatsink falls off, rather than making those Linux kernel
"CPU idle" calls actually do anything.
- Uninterruptable power supplies. These were the sleeper hit of
my power measurement experiment: with full batteries and no devices on the
load side, my UPSes drew 50-80 watts of power each. I understand that
filtering power comes at a cost, but these things really should be designed
to be at least a little bit more efficient than the average space heater.
So, this brings me to my main point: why is it that my cell phone can run for two weeks without a recharge, my digital scale can run for 10 years (guaranteed) on a single battery, my thermostat, analog clocks, and smoke detectors can run for 2-3 years between battery changes, but my computers and consumer electronics have to suck up as much power as my toaster while they are completely idle?As long as our toys are designed to waste as much energy as legally possible, even the most well-intentioned power conservation efforts are doomed to utter failure.

I suppose you prefer the visual beauty of a strip mine?
I applaud the Danes for their bold, foward thinking Energy 21 energy policy. Bush's policy on the other hand, involves meddling in the middle east or drilling in our national parks and preserves.
Being the man of vision that he is, Bush, should reconsider our depenence on oil from the middle east and its impact of our foriegn policy. Like a drug addicted individual the US governments choices sometimes are far from rational.
For example, we call the Saudi's "our fiends". Bullshit! They would slice our thoat in a heart beat if we were not their biggest customer. They are a twisted theocracy that rejects womens rights, democracy, personal liberty, religious freedom, etc. We have nothing in common.
If the man would come out with a Kennedy like vision and plan of developing renewable technologies such as wind, solar, geothermal, wave, conservation, etc. and even clean and safe nuclear we would be much further down road to world stability, peace and prosperity. Instead he wants to start another war and one which has the potential of being a messy urban war where civilian casualities are unavoidable if you want to win.
Why can't the US, the world's largest economy, do the same?
Your citation of Dr. Moore shows what, exactly? That some in the left wing disagree with some others in the left wing? Oooh! Just because Greenpeace gets more involved in politics in the process of protecting the environment, and this old-schooler thinks they should proceed a different way, that doesn't mean Greenpeace is doing anything wrong. The thing about the lacking science education is true up to a point, but exactly how many science Ph.D.'s are memebers of Greenpeace? One that I know personally, and I bet you there are tons more. Yes the average environmentalist hippy doesn't know much about science, that's unfortunately a fair observation, but why should we hold them to a special standard regarding this? After all, only a right-wing nutcase could possibly think the average Greenpeace hippy knows less about science than the President of the United States.
Unfortunately the demand for wood is already so high that forests worldwide are being stripped faster then they can regenate.
War is necrophilia.
Well let's say you happen to own some land and you have a little cottage there that you visit every summer. Then someone wants to build a few dozen windmills and they put it infront of your cottage?
The problem is that few people live near the coast and people who vote for the windmills live in the city. Also, surprise surprise, more people live in the cities, so our democracy gets its way, so let the people at the coast suffer and make all the hypocrites in the city think they made a favor to their environment.
My cousin who is a so called "green" and lives in the Finnish capital Helsinki, opposes nuclear energy, opposes fur-farming, wants people to do catch and release when they fish etc. etc. Now when I asked her about the placement of these windmills, she simply told me it's not her problem. Well I'm quite sure she wouldn't want one of these in her backyard.
Besides these windmills have a very annoying low frequence sound. If I'm disturbed about it, then how about animals that usually hear a lot better than humans?
Yup.
They know they've got mountains, with rivers descending gradients thus making suitable sites for hydro schemes. Denmark has no mountains.
They know they're sitting on a tectonic fault line, where geothermal energy can be tapped. Denmark has no tectonic faults.
I can't help getting irritated with the ignorant American assumption that what works for them in their particular location will work for everyone everwhere. It won't. In Iceland, where they have plenty of geothermal energy, they power domestic heating, aluminium smelters and spa baths directly from geothermal sources. Works for them. Here in Scotland (and also in Norway) we have a lot of rain and a lot of mountains, so we have a lot of hydro-electric power. Works for us. There are places in the world that have lots of sunlight, and can realistically expect to generate some proportion of their energy needs from solar power.
The Danes don't have any of these advantages, so they have to do the best they can with what they've got. Which happens to be wind. The Danes aren't stupid. They aren't perverse, or ignorant, or backward. They live on a flat sandbar with few mineral resources in a cool sea, and they're doing it well.
I'm old enough to remember when discussions on Slashdot were well informed.
You shouldn't be so defensive -- nothing in my post implied that Americans are smarter or more advanced than people in other countries. Simply that I knew of an organization that had an interest in pursuing wind power but chose not to use it.
The great irony here is that as you were sitting in Scotland writing about my American arrogance, I was lying awake in bed late at night in America avidly reading a novel by an author who resides in Edinburgh. I have plenty of respect for the intelligence, abilities and achievements of people outside the U.S.
