there is no way to sequester the millions of tons of CO2 USA produces each year.... it's a pipe dream propaganda as is the myth that ethanol is the solution. Conservation is a real solution... but Exxon-Mobil won't hear of it. And they control the whitehouse

Conservation is the biggest part of the solution, but alternative energy sources are a critical component as well. Energy sources that utilize carbon from the atmosphere (via crops), do not add to the total atmospheric carbon content. The trouble with ethanol is it is energy intensive to produce, while containing less energy; it burns hotter than petroleum, and thus produces more NOX; and puts a strain on food crops, while many millions are starving. It is a necessary step in the direction of "oil independence".

More desperate efforts by the coal and oil industries to preserve their empires. They say they could get their first operational plants up by 2025? OK, but when would the technology be implemented on the massive scale required to avert drastic climate change?

If alternative energy sources had received the same level of funding as the fossil fuels, they would be in a much better state than they are now.

Agreed!

Carbon emmisions from coal fuled power plants have been reduced approximately 70% within the past 30 years. This is good because in the next 30 years this should be down to 5% in comparison to 30 years ago. The environmentalists can bawl, squall and whine all they want to but coal is in hot demand right now. Im glad it is and i hope the demand gets even hooter to the point the environmentalists get burned for good.
We have a republican president finishing out his second term and the senate was also under republican control for quite some period of time.
Im thankfull Bush is second term president and the senate was under republican control for that time period. This has allowed the coal companies to grow strong and help supply the demand for coal. Coal is plentifull and cheap to mine and the jobs that accompany coal mining pays better than some folks whow have a college degree earns.

Muckerman is right about coal being the answer to oil independence. The US has one of the largest coal reserves in the world has the capability to get us out from under the thumb of the Middle Eastern countries that are laughing out loud at our plight.

Environmentalists have for years kept the US from exploiting its natural resources and are responsible to a great degree for the economic meltdown.

China has no such worries about the environment. They burn coal, oil, natural gas, coke, charcoal and wood. They would burn dirt if they could.

I am located in West Kentucky and im glad to see the booming demand for coal that we are now experiencing. We have young men and women with college educations seeking employment in the coal industry because they can make more money mining coal than they can make with their college degrees. I know several twenty year old young men who are buying $150,000.00 houses and $300,000.00 farms because the mining jobs pay well enough to allow them to do so. Some of the "old timers" who upon retiring from the mines will have accumulated over $750,000.00 in their 401k plans.

The mine operators arent the wicked hell bent evil doers the the environmentalists have portrayed them to be. They have provided excellent paying jobs that have allowed the american dream to come true for so many of the small town people i know.

What is rarely discussed is that exctraction of the CO2 costs about 8% of the thermal efficiency for a 44% efficient plant, so you are incrasing the CO2 generated by ((44/(44-8))- 1) or about 22%. That also means 22% more coal and this is BEFORE the problem of where to put it.

A plan to extract it from air ( not needing CO2 extraction at the plant ) would be more effective. Some extraction can be done for industrial uses ( such as soft drinks, solvent extraction, etc ) or it can be used to provide enhanced CO2 levels in greenhouses and 'microalgae bio-oil' generation.

A plan based on 'ideology' and 'publicity' suchas the 'Capture and sequestration' coal bandwagon is the least effective use of public money.
