I dont know if the specifics are true or not and if, or by how much, the "truth is being shaded." I assume the Energy Star program was the primary source and was subject to internal review... and the Discovery Channel and others are simply repeating it or citing it.
I do know that using CFLs provides a significant energy savings.

Most electricity in the U.S. is produced by coal-fired power plants (the greatest source of greenhouse gas emissions). The problem is that for every kilowatt hour of electricity generated by a coal-fired plant, the EPA estimates that 1.43 lbs of greenhouse gases are released into the atmosphere. By switching to CFL light bulbs, you lessen greenhouse gas emissions.
