Carbon vs Coal vs Environmentalists
The “New Source Review” regulation administered by the U.S. EPA and supported by many environmental groups is a sham.
Some of the more extreme environmentalist, who are working to totally get the U.S. “off” from any use of carbon including coal. These groups are being intellectually dishonest when they insist that renewables can immediately replace coal which accounts for 50% of the electricity produced in the U.S. at prices that help to make our manufacturing sector cost competitive with foreign companies.
Currently renewables minus hydro equal at most, about 4% of our needs and they are not reliable as a base load due to their dependence upon external factors such as wind and sun! To ensure we have electricity when we turn on the light switch or maintain medical equipment, we need a base load that is reliable. At this time, renewables do not afford that reliability. Therefore, to advocate we can do away with coal is dishonest.
Coal fired power plants have the ability to develop more efficient operations but are precluded from doing so because of the “New Source Review” regulation. This requires any non maintenance improvement at a facility to make additional improvements which are prohibitive due to the high costs versus simply investing in the efficiency only upgrade. This needs to be changed because the environment is missing out on some easy low hanging chances to reduce carbon emissions due to the rule which is considered sacrosanct to the “environmental” community.
To gain a perspective of the scale of coal’s opportunity to contribute, consider this: if we were to improve the efficiency of the existing coal power-generation fleet by only one percentage point, that is to increase from 32% to 33% efficiency (which is well within the present technology’s capability to do), we would save more energy than we would gain by expanding existing wind generation capacity twelve fold! This increase in efficiency would also result in a 3% reduction in CO2 released from coal-powered generation for the same amount of power delivered.
Going further, if we aggressively improve efficiency by 4 or 5 percentage points, then emissions could fall by 25 MMmt 0, or about 13% of last year’s CO2 emissions from coal power (n.b. another example of why reducing carbon intensity is a worthwhile goal, but stymied by NSR problems).
Extrememist in the environmental movement don’t want incremental, practical change. Chaos, controversy and excessive pollution helps their cause...and hurts our society and environment. Their “politics” of extremism is bad for America and bad for the world we will leave behind to our children.
So when you hear them pitch their new “Cap & Trade” policies, the devil is in the details and for all practical purposed, Cap & Trade is designed to be one of the biggest tax hikes in America’s history. If they really wanted to see carbon emissions reduced, there are practical alternatives available now!

you are not making sense and not citing your damn sources.
stand up for your damn work.
10 to 15%
...of the total efficiency of the generator is in the design of the last stage blade.
More later. Tired now. Been doing six 10s at the power plant (condenser).
One of the ten most clean power plants in the US by the time it is finished.
The steam expands...
...as it passes through the generator, whiile maintaining the same pressure. Thus, the blades at each stage (18 of them) are longer than the one before it. By the time you get out to the end of the last stage blades, the thing is going faster than the speed of sound.
Only 20 years ago this was not possible. New materials have been developed that will sustain those conditions.
The new coal plants going up are not the traditional coal-fired power plants; they are super-critical steam generators, ie they have operating pressures of greater than 3000psi and temperatures greater than 1000F.
The emission systems going in them were developed in Germany and Japan in response to the acid rain problem in the late 80's to early 90's. Some of them have new systems to produce ammonia on site rather than having it trucked in.
The lifespan of a power plant is about 50 years, and we have some in operation that were built (with the latest technology!) in the 30's and 40's. Those need to go.
Alternative energy has a place, but right now, I'm not so sure what it is.
Wind energy provides an unstable power source. When used as greater than 40% of the power source, it reduces the lifespan of the equipment. As a general rule, the lower the operating voltage internally in an appliance, the greater the decrease in the lifepan of that appliance.
Also, the footprint of wind energy must be considered. It takes over 6 times the same amount of land to produce energy with wind than with coal or nuclear.
Its greatest benefit, as I see it, is to get the farmers off of government subsidies by having them rent out space to these windmills. Still, if the subsidy is going instead to the power producer, it's a zero-sum game-- no gain.
Solar looks good for peaking facilities, but really its efficacy is based on a societal transition toward a point-of-use power generation strategy. Could happen, but I'm not holding my breath.
1. you should speak to Senator Dorgan on the issue of
capacitance in our power grid. I KNOW we've got money in the stimulus to support building in more capacitance, which will allow more sporadic electricity generation (wind, solar).
2. Yeah, nothing beats fossil fuels for transporting energy around... at least not yet.
3. I'm not totally anti-coal, I feel like we need to transition away from coal, but that we've got a hundred years to do that... Nuclear? I want to see the stats on building and maintaining plants, and expected uranium deposits -- it really looks like we're at half of peak uranium, and like building a lot of plants might not be the bestest of solutions. Not anti nuclear either, though what I've heard about radiation poisoning out of TMI is rather distressing...
Saul, you work for Newt's "American Solutions"
Saul, you work for Newt's "American Solutions".
A major source of funding for Newt's "American Solutions" is the coal industry.
So, my point A: I see right through you.
While you were still chairman of the Michigan Republican Party you presented a platform written by American Solutions - including, surprise, tax breaks for the coal industry. You were defeated.
So, my point B: will you never learn?
Here's America's Solution
From the adults that have taken over. Thank God.
And you thought Bush was stupid.

geoengineering is a very risky solution.
I hope to dog conservatives don't sully their movement by forcing us to take it.
Its not the conservatives
but I see where you're going.
BTW-Did I see where you have three months notice on your job. If so, good luck finding something quickly. You are obviously a very bright person with a lot to offer.
thanks!
If the conservatives keep on stonewalling on the basically common sense, "proportional to the problem" provisions, we will have to try the riskier options later. And those risky options don't feel very conservative to me.
Whom does sanuzis work for?
This blog entry reads like a coal industry press release. Is that what it is? Is the author a coal lobbyist? Let's have some transparency.
Saul works for Newt
Saul is a paid employee of Newt's "American Solutions". "American Solutions" heavily funded by the coal industry. Coincidence??
Thank you for this
Thank you for this informative read, I really appreciate sharing this great post. Keep up your work. burs
