$15 billion - what we got for it.

From the white house release of the SOTU:

Including The 2008 Budget, The Federal Government Will Have Spent $15 Billion Since 2001 To Develop Cleaner, Cheaper, More Efficient, And More Reliable Energy Sources.

Ok. $15b spent and what has been achieved ? Where are the "cleaner, cheaper, more reliable energy sources" ?
There aren't any. Not any significant quantity. Nothing. All we got for those 15 billion bucks is hot air, rhetoric. They have joined all those billions spent by presidents Clinton, Bush 1, Reagan, Carter for "new" energy- down the drain.
