Re:i am chinese and i am pretty impressed (Score:5, Informative)
Because no one can predict with any certainty what China's energy needs will be ten to twenty years out, any predictions of this sort are guesswork at best -- pure marketing at worst. The fact is, over the last decade power availability throughout the area to be served by the Three Gorges dam has consistently outstripped demand, meaning there is currently a power glut. This may well change in the future, but no one can say for sure.
I had a final chance to visit the Three Gorges last August, with a tour guide who was an unabashed mouthpiece for government propaganda. Coincidentally, there was a Canadian hydro-electric engineer in our group who had worked on dam projects around the world. He asked some very pointed questions, making the tour guide very uncomfortable.
One of the biggest potential problems with the dam project is silting. All dams eventually silt up -- all the detritus normally washed down river kept afloat by the currents settles out as the currents slow, eventually building up behind dams and other obstructions, rendering all dams eventually unusable.
The Three Gorges dam is different only in the unprecendented scale of the problem. The fact that the Yangtze is both one of the largest and one of the most silt-heavy rivers in the world makes conventional de- and anti-silting methodologies utterly inadequate and makes the the success of the project heavily dependent on experimental and largely untested (Gezhouba Dam notwithstanding) methods. Should these methods fail to perform as projected, the dam -- more than twenty years in the making -- could silt in in as little as ten years, making it one of the most costly debacles in human history.
Amazingly, the project has not even attempted to address the other silting problem. As the mighty Yangtze rushes into the upper end of the reservoir near Baidicheng -- 360 miles southwest of the Dam -- the sudden slowing will deposit by some estimates thousands of tons of silt per day, eventually resulting in massive flooding problems along the entire riverway from Chongqing to Yunyang.
There are no plausible alternatives currently, you see.
This is simply not true. In the years since the Three Gorges project was begun any number of alternative technologies have appeared. Gas-fueled combined cycle plants and co-generators, for example, produce virtually no pollution or greenhouse gases, are smaller, safer, cheaper, more reliable, less sociologically or environmentally disruptive, and more adaptable -- meaning they can be constructed relatively quickly to meet demand and can be located near the need. This last point is not insignificant, as transmission leakage will consume a large percentage of the power generated by the dam. By some estimates, transmission losses from the dam to Beijing could run as high as 70%. As natural gas becomes more prevelant, combined cycle plants will become even more economically attractive.
Which leads to the next problem: the project is already facing severe financial difficulties. Nearly every original investor has fled, and the few that haven't already pulled out are in the process of doing so, leaving the government to foot nearly the entire bill. While Beijing has attempted to put a bright face on this, the fact remains that few investors expect the dam will ever turn a profit, both because of the immense (and growing) construction costs -- not helped by the massive corruption which has dogged the project -- and because newer, cheaper alternatives threaten to undercut the dam's market before construction is even completed. The fact is, hydro-electric dams are outdated both technologically and economically.
Most of the sociological impact of the dam will takes years to manifest. To date, the government has relocated less than half the two million people who are being displaced. Our tour guide gushed with pride as he showed us the shin

The dam is going to devastate the local ecology to a degree not seen since the Aral Sea debacle. Most of the rivers feeding the Three Gorges are heavily polluted and hundreds of factories are being flooded by the dam. Despite cleanup efforts it is inevitable that hazardous industrial chemicals are going to end up floating about in the reservoir. Add the industrial waste to that created by the ocean frieghters navigating the new reservoir and you've got a gigantic cesspool in the middle of the country.
Besides the pollution the local wildlife is going to end up wiped out. Without the silt in the river being distributed down its bed the fish will have nothing to eat if the pollution doesn't kill them first. The Baiji dolphin is also on the list of animals to be impacted as they hunt through the river's silt for food as well. Water fowl that feed on the fish that won't be there will also begin to die off unless they manage some heavy migration. Even if they manage to find new food sources their numbers are going to dwindle drastically. Worst is the people in the area that depend heavily on the river's fish stock. They're going to have a signifigant food source closed off to them which means more food imports to the area which will only exacerbate the poullution problems.
Of course there's the potential for a massive flood. The dam is already showing signs of wear. Saying the dam is earthquake resistant in a misnomer. Natural earthquakes pose less of a problem than the masses of water in the reservoir putting pressure on the local tectonic system. Also the massive build-up of silt in the reservoir is a distaster waiting to happen. A small earthquake that normally wouldn't damage the dam stands a decent chance of causing a mudslide in the silt bed. Megatons of silt crashing to the basin floor will cause pressure waves that can seriously damage the dam.
A number of proposals and arguments are on the books and the project was started despite them. Most proposals suggested a smaller number of power stations could be built on the Yuangtze's tributaries. They could have provided as much power as the single dam without the ecological damage and vast potential for a catastrophic flood. The lakes and wetlands downstream from the Three Gorges area also are able to hold more water than the reservoir but allow but better distribution of the water.
The dam is most definitely a political show of pride than it is a practical solution to a problem. Save for ocean freight in Chongquin the alternative solutions to the TGD provided everything the TGD did for a lower cost and less economic and ecological impact. It is arguable that Chongquin NEEDS the ocean freight, it is polluted and choked as it is, adding to those facts is not a very good idea. The corruption brought to light in the project of late and the total silencing of opposition to the project should tell you this whole plan is nothing more than the world's biggest political stunt.

no matter how you justify any project today there is one thing that is not being even thought about or designed into any major building endevor currently - lasting beauty.
You may look at a skyscraper that going up - or recently built, or see a large structure that was designed - and it may SEEM to be beautiful, but generally they are not. We are currently confusing awe with beauty. We may be in awe over the size of a project or structure - and awe is a beautiful thing - but it is not beauty.
This is a seriously important aspect of design. If you look at all the buildings in your city as you drive around - find any that are beautiful works that will alst and be appreciated for their beauty alone for any length of time. It will be exceeedingly difficult to find any large number of structures that can actually be classified as beautiful and meaningful.

You would be surprised at just how much an affect of a beautiful environment can actually have on your life.
The point with the Chinese and the dam is that this project is taking the trash designed life to the extreme expression. The largest piece of man made trash in the world - so big that real beauty and human creative effort is obliterated in its shadow, the real and true principles of the human creative spirit are ignored and killed in the name of progress.

Plus, that assumption is based on a PROPER construction with NONE of the inferior materials that have been used.
For example, instead of using concrete that has been designed to withstand tremendous power, inferior concrete was used. Instead of using the concrete that can STRETCH and FLEX so that it won't break, much cheaper rigid and fragile concrete was used.

I'm currious if anyone knows of studies which look at power generation costs from a global, as opposed to local, perspective. For example, even with damns, I could forsee global impacts that would effect others not benefitted by the power, e.g., fewer salmon mean less seal food and thus, fewer seals. Cultures reliant on seals for whatever reason, may be unfairly burdened with the costs of power generation.
This obviously doesn't address the archeological destruction caused by the Three Gorges Damn - significant archeological evidence should be considered a world heritage asset, and be taken into consideration when constructing a damn.

Aswan Dam was unwise. The project was far more expensive than expected. Further, the annual floods carried silt, which created the topsoil needed for plants. Since the creation of the Aswan Dam, the farms on the formerly flooded banks have had to use expensive fertilizers in place of the silt. Formerly, fish have fed on the silt, and the people downstream depended on fishing from the riverhere

Now, I'm not suggesting that the Proletariat sieze the means of production. Just that enough food be given away, in addition to paid exports, to make sure that people at least get a basic diet.
In addition to this, the most crucial thing is EDUCATION. Give a man a fish, and he'll eat for a day; Teach him to fish, and he'll eat for a lifetime. Teach people modern farming methods, give them the necessary equipment, and you'll suddenly see that no one is starving anymore.

if I had to move because I'd be saving people's lives? well fuck, wouldn't you? Btw, did you know that when shit like this happens (government forces you to move), they pay you a whole lot of money, at least in chinese standards? I am not personally familiar with that particular province, but in nanjin and shanghai, when farmers were kicked from their lands (when building new airport / new highway / mag-lev train / etc), the farmers got a LOT of cash for their land - in fact many of them are off to quite a good living, even better than some of the city-folks.
btw; most man-made channels silt. there are specific ships that dig those out. read about them. the technology is there. and don't forget that yangtze is a lot bigger than mississipi; so percentage-wise the silting should not be as bad.
btw; i mentioned it in another post but i say it again here - partly I think the government believes that this will become like the great-wall, etc, where they are creating a new legacy; at least thats what i think they thinks about when confronted with destroying the archeological stuff that lies the river's side.

Anyone want to wipe out the lower half of China has now been given a perfect missle target. Although much ignored by Western media, note that China also faces Uygurs terrorist (otherwised called "freedom fighters" by Western media) threats connected with al Quaeda in the XinJiang Province.
Fact: Some Uyghurs have been implicated in bomb attacks (I don't believe any attacks took place outside of Xinjiang).
Fact: The Communist Chinese government has forcibly moved millions of Han Chinese into Xinjiang over the past 50 years in an attempt to pacify the Uyghur population.
Fact: The Uyghurs are neither Han nor Chinese--they are ethnically Turkish, look different from the Chinese, and speak a language that is mutually intelligible (with difficulty) with the language of Turkey. Before they were conquered by China over 50 years ago they were an independent nation. It is true that this area had been under MARGINAL Chinese control off and on for centuries (there were 42 results under Manchu rule for instance). As a side note, this area has oil. Coincidence that China cares about it?
Fact: The Chinese have not had the best track record dealing with minorities or hunman rights in general (Inner Mongolia, Tibet, East Turkestan, etc etc).
Fact: AFAIK (and AFAAK) the rumored links to al-Qaeda are just that--rumors. Until proven otherwise, they are as insubstantial as links of Saddam to al-Qaeda.
So in conclusion, this is simply another minority group (again, see Inner Mongolia and Tibet for the other two most publicized examples) that is being horribly treated in China--and no one cares because of business opportunities...

Yes, this dam will damage the environment.

Yes, it is dangerous in terms of earthquakes and flooding if it collapses.
BUT, it is going to generate *18.2 MILLION kilowatts* of power, indefinitely, with no ongoing pollution. The alternatives are presumably:
- coal or oil power, causing a massive amount of greenhouse gas, contributing to global warming (yes it does exist, America) and drawing fire from the same people who are criticising the environmental impact of the dam
- nuclear power, leading to large amounts of nuclear waste and with an increased risk of a meltdown occurring in a 2nd/3rd world country with dubious safety records and high levels of corruption
- China goes without power, and the western world continues to get fat and happy using our own dams, nuclear plants and coal fired power stations and sweet sweet Iraqi oil
Obviously the ideal solution would be for China to be able to build a project that produced this much power from solar/wind/tidal energy sources, but the cost at present would be insanely prohibitive. Quite frankly I have more respect for the energy policy of a nation that is trying to generate power without relying on fossil fuels and nuclear reactors than one that is actively trying to expand its power generation in those areas. Of course no other countries I can think of have built massive, environmentally questionable (*cough* Hoover *cough*) dams, have they?

In some ways, the Chinese have the advantage of industrializing at a later date. For example, when people get phones there, they are much more likely to get wireless. They're skipping over the cumbersome copper phase of telecom to a large degree.
OTOH, they've failed to learn our lessons in other areas. I recall reading an article about how the once ubiquitous bicycle is being pushed out by cars. People who try to stay with their bikes are riding around in smog, finding it hard to breath, and of course they are dead meat in a collision now. Smog was a major point of contention in granting the Olympics to Beijing. Solution? Nearby industry will be shut down during the games.
It's too bad the government there is sold on this particular vision of "progress". If I were dictator, I'd tax cars and gasoline like crazy and use the revenue to build public transit. As for electricity, many Chinese did fine without it for most of history. If China wants to play a global game of "keeping up with the Joneses" they are free to do that, but it's just a larger scale version of the yuppie who knocks himself out 70 hours a week to keep the Mercedes and the crackerbox mansion, only to discover that his wife is sleeping around and his children don't respect him.

I honestly don't know about the nuclear power. That was outside the scope of my search so I can only estimate that yeah, there would be a buttload of nuclear waste.
I will say this though, with a body of water that is this large (long, not wide) that the salinity of the water will increase (as is found in other large bodies of water and other dam projects), as such, with this stretching long periods, the watershed is also expected to become saltier and the plant-matter close to the water is also expected to suffer.
These are only the negatives, downstream where there are large amounts of citrus fruit and the "bread basket" of China is located (presumed to be the second largest until the Taiping Rebellion) will now have stabilized flow of the Yangtze River instead of the traditional seasonal changes of approximately 30 meters in depth.
China isn't *controlled* by the communist party, its controlled by the rivers. Rivers in China change course often, and when they do, approximately 1.2 million people die each year due to either flooding or starvation with a poor crop (figure obtained from in class lecture, will find an online source if asked). China lives "on the edge" of starvation constantly with only 12% of their land being arable, so when a river moves, its BIG NEWS. This will be the first time that many farmers downstream are able to install permanent irigation.

Also consider that all of us typing these posts are doing so via computer. As we continue to push clock speeds higher and higher, power consumption in processors increases - power consumption in CMOS is something like cfv^2 (f: frequency, v: voltage, c: capacitance) so the faster we run'em the more power they take. Now consider that a 2GHz Athlon or Pentium packs all the power that your average Joe user will ever need - perhaps now that these processors are consuming in the 75 to 100 watt range, we should be putting more effort into reducing power consumption, instead of increasing clock speeds?
