Why is Siemens advertising now?

Bloomberg reported on May 27, 2010 that "Vestas, Siemens Wind Bets at Risk on Cheap Gas, Subsidy Loss". So now Siemens is advertising. Perhaps Siemens needs some more windy subsidies to support their investments. Siemens probably agrees with Senator Lamar Alexander's recent (2011) advocacy for "Wind Energy Subsidies".
