Prominent environmentalists, including Dan Becker, director of the Sierra Club's Global Warming and Energy Program, believe that the term clean coal is misleading: "There is no such thing as 'clean coal' and there never will be. It's an oxymoron". Complaints focus on the environmental impacts of coal extraction, high costs to sequester carbon, and uncertainty of how to manage end result pollutants and radionuclides. There are other forms of clean and renewable energy such as solar, wind and hydroelectric which are supported by many of the environmentalist groups and campaigns.
Critics of the planned power plants assert that there is no such thing as "clean coal" and that the plant will still release large amounts of pollutants compared to renewable energy sources such as wind power and solar power. They also point out that the continuing construction of coal-powered plants (whether or not they use carbon sequestration techniques) encourages unsustainable mining practices for coal, which can strip away mountains, hillsides, and natural areas. They also point out that there can be a large amount of energy required and pollution emitted in transporting the coal to the power plants. Some people contend that sequestrian technology has yet to be used or proven on such a large scale and that it may not be successful, lead to unexpected geological instability, contaminate groundwater supplies, and that sequestered CO2 may eventually "leak" up through the ground. There are also concerns that plans to possibly pump some of the sequestered CO2 into certain oil and gas reserves to help make the fuels easier to pump out of the ground will lead to increased concentrations of CO2 in potential fuel supplies which would have to be burned off during the refining process, thus adding to global warming.
It appears to me that Senator John McCain hasn't done his "homework", when it comes to clean energy and America desperately needs a President that will do the "homework" necessary to begin solving the economic, energy and environmental problems facing America and the world today. Sounds like Senator Barack Obama to me.
