An alliance of 17 states and a number of environmental groups and American Indian tribes had challenged the Bush administration, when the Environmental Protection Agency (EPA) in 2005 proposed to exempt power plants from the new rules of the Clean Air Act. The regulations were set to take effect in 2010 and would have allowed power plants that failed to meet targets for mercury to buy credits from plants that did better than their targets. Environmentalists argued that this cap-and-trade system was inappropriate. The court invalidated the EPA's plan to adopt such a so-called cap-and-trade program that would have let power plants buy and sell mercury pollution credits.
U.S. coal-burning power plants -- which supply about half the nation's electricity -- are the single largest domestic source of mercury emissions. The EPA estimates they emit 48 tons of mercury into the air each year, with 11 tons deposited onto soil and surface waters. The
National Academy of Sciences estimates that 60,000 newborns a year could be at risk of learning disabilities because of mercury their mothers absorbed during pregnancy.

Mercury is showing up way too much in fish, especially tuna (the apex predators).
The FDA is not regulating the levels in food in a manner protective of the consumer...
"Healthy" levels vs. the levels the FDA are regulating to are two different things...
It's not a matter of "shutting down the plants and sitting in the dark" (that's just plain silly and an immature statement)...
There are such things as cleaner burning plants and currently there are methods of upgrading old plants to be cleaner...
The choice the EPA Wanted to give the old plants was an 'Out' from having to upgrade by "buying" "pollution credits" ...
The EPA could have said, "you Have to upgrade all the dirty plants"...
It's a matter of cost not a matter of current Technology...
It is Greed plain and simple...
Either way ... Somebody Pays...
But here is a worthwhile suggestion regardless of where anybody stands or what they think...
Don't eat so much Tuna, Swordfish, etc. (watch the sushi especially)...
Do some research. Look into it...
This was a great ruling, and it is a shame that it had to wait so long. Bush has been able to run out the clock on too many things.
The greater issue on coal burning power plants has to do with carbon emissions. You can't "scrub" the carbon out of the emissions, because coal is mostly carbon. We do not yet have a practical way to sequester the carbon from burning coal, though we talk as if it will happen. We are in a bad place on this.
This was an excellent Article, Sam.
David, you had some very good comments, yourself here. The mercury is not only in the Tuna in heavy levels, it is in most of the fish in heavy levels. Mercury is just one of the many things that has infiltrated the fish.
Just thinking about all of the sewage spills (during Katrina for instance) -- (here in Florida recently) -- makes me SICK. I'm very sensitive to mercury levels in sea food. I'll never forget a BIG-lip bout I had with some fish years ago. I dare not try eating fish out of the sea now. In fact, I won't eat fish of any kind, unless it is farm-raised.
Thanks Sam for this informative Article.

As to existing plants, we should look at decommissioning, which means that we need to make even faster progress with renewable alternatives. The cost of decommissioning and cleaning up sites is huge. Therefore, it may be more economic to convert existing plants to geothermal - drilling pipes down into the ground could circulate water and steam, driving the turbines that are now driven by coal-fired steam. I remember someone - many years ago - suggesting that new coal-fired power plants should be built on sites where the soil could be more easily drilled, for purposes of possible conversion into geothermal later. Pity that nobody listened then!
Both the price of coal and the costs of sea and rail transport are expected to keep rising, while the cost of mining is also likely to go up with increasing calls for stricter standards there, as discussed in this article in Orion Magazine, kindly pointed at by Steve.
Note also that it's hard for coal-fired power plants to adjust their output to supply and demand. Currently, oil generators supply extra power at peak time, sharply increasing the cost of electricity.
In conclusion, it makes sense to look at better alternatives. Wind and solar power can provide electricity in abundance, which can be stored in hydrogen and batteries for later usage. This scenario can provide a clean, safe and price-competitive alternative to coal-fired power plants.
Hopefully the big wind generartor manufacturers will soon start producing windmills that can provide 1-12kw for the homeowner at a more reasonable cost, right now everything is geared toward large scale or too small for practicle, & cost are too high for a decent payback.

As the article in Popular Science that you mentioned reports, Nanosolar can produce solar material at a cost of $0.30/watt or $300 per kilowatt. Solar panels are commonly scheduled to remain active for 30 years, but let's conservatively estimate that it will last for 25 years (the warranty is 15 years) and will deliver the equivalent of 4 peak hours of sunlight per day. That would deliver 1kw*4h/d*365d/y*25y=36,500kWh over its lifetime, so the cost per kWh is 300$/36,500kWh=.008218$/kWh or ~ 0.8 cent per Kilowatt hour. That is less than 1 cent/kwh and cheaper than electricity currently produced by newly-built coal-fired power plants or nuclear plants. Further advances in nanotechnology, such as nanowires, promise to deliver flexible panels with substantially higher output.
When you install panels at home, there will be some extra cost, as you have to pay retail prices and you'll have to add cost for installation, inverters, wiring, batteries, etc, but homes in sunny areas will have more than 4 peak hours of sunshine, while electric cars could provide the necessary batteries. Furthermore, consumers will rarely pay less than $0.10/kwh due to the cost of the grid. As more wind power becomes available, cost of off-peak power should fall, making it attractive for consumers to buy such energy at low rates, store it in batteries and feed it back into the grid at peak times. Attractive feed-in tariffs - such as in Germany - could help establish a more distributed grid, as described in my article The Distributed Grid.
It's not ignored at all, Charles. Some areas do get plenty of sun and they'll go for solar energy in a big way. Other areas get plenty of wind, or have a lot of potential for geothermal energy, and that what will become prominent there. Yet other areas will prefer to import most of their electricity. Electricity can be easily transferred over thousands of miles using High Voltage Direct Currency lines (HVDC) lines. Government should not prescribe what technology is to be used, it only needs to implement a framework of fees on polluting activities with the proceeds used to fund local rebates on clean and safe alternatives. Market mechanisms can best sort out what works best where.
As I mention in my article Reinventing the Wheel, using concentrated solar thermal energy, facilities to power the entire US grid – day and night - could fit in a 92 mile-sided square piece of desert land, at a price of about $0.10/kwh. This corresponds to less than 10% of the Federal land in the state of Nevada, land that could be made available without taking away land used for farming.
Obama's EPA this month announced plans to develop MACT (maximum achievable control technology) standards for electric utilities, which would force each individual plant to curb their emissions as much as possible, as opposed to the Bush administration's cap-and-trade approach that the federal appeals court struck down.
