There are a few German language peak oil websites, including this forum:
http://www.oelgipfel.de/ - most posts are (not surprisingly) in German. My impression, based on a quick scan, is that there is more emphasis on the pros and cons of different technological responses than here on PowerSwitch.
and this site:
http://www.peakofoil.de/ - this site covers all the familar peak oil themes and would be useful as a web primer to send German-speaking friends or relatives.
If you can speak some German but are stuck on some of the words, there's a great, online dictionary here which helps.
