From the Executive Summary of the report
http://www.eia.doe.gov/oiaf/servicerpt/subsidy2/pdf/execsum.pdf, pdf page 6 of 8. That page includes a table of subsidies paid per mwh of generation. A quick summary (subset) below:

Coal is paid $.44 per mwh
Nat. Gas: $.25 per mwh
Biomass: $.89 per mwh
Nuclear: $1.59 per mwh
Hydro: $.67 per mwh
Solar: $24.34 per mwh
Landfill gas: $1.37 per mwh
Wind: $23.37 per mwh

The EIA is quick to point out that these numbers reflect a moment in time and that subsidies varied for other generation sources over the years. Note, these numbers do not include the millions spent on DOE programs aimed at bolstering wind energy as the renewable of choice.

It's apparent the Federal Government, in fact, does NOT treat all renewables equally, as do most State RPS programs. Rather, the federal government has decided to enrich wind.

Why?
