The article in the link is almost complete BS apparently written by anti-fossil fuel nuts in hopes that no one actually reads it. Did you actually read it? Do you understand the difference between a subsidy (money given directly to a target group and not expected to be paid back) and tax breaks/treatments? There is a substantial difference and anyone who calls a tax break a subsidy is a pretty much either an ignoramus or, worse, a liar.
While there were some references to some direct subsidies for research listed, those did not seem to amount to much, although I admittedly did not take a calculator to the numbers so I could be mistaken.
