Via the WSJ energy blog, follow the money:

Since 1999, federal energy subsidies have more than doubled-from $8.2 billion to $16.6 billion in 2007. Who gets the most?

‘Renewables’ landed $4.8 billion last year, but that includes $3.25 billion for ethanol and other biofuels.

Coal and cleaner-burning “refined” coal took home $3.3 billion, while the nuclear power industry got $1.3 billion.

In all, about 40% of the energy subsidy pie went toward electricity production; the rest for things like alternative fuels and energy conservation.
