We need to change public opinion about nuclear then. Thorium reactors are the future (or Fusion if we get a breakthrough that makes it possible then a lot more viable).
Wind power generation pulls energy from the motion of the air. Air/Wind is what moves Heat around the atmosphere, thus managing it's distribution. Converting that to energy to fight AGW is asinine. Plus it's not sustainable/consistent (i.e. wind isn't in a location 100% of the time).
Solar isn't efficient or cost effect enough yet (as your Germany example shows) to be worth it, and although that could change in the future, I'm not holding my breath for it. Plus although it's mostly consistent (aside from clouds), it isn't sustainable 24/7.
Geothermal is good but only in certain locations and we don't know what potential pitfalls it has (think what fracking has caused, but with heat and lava although Geo isn't nearly as extreme as Fracking is).
I honestly only see Nuclear Fission/Fusion as a viable, sustainable, and cheap/abundant energy source for the near (20-100 years) future.
