CBCs The Fifth Estate has produced an excellent documentary on Germany's transition to renewable energy and the challenges and roadblocks facing renewable energy entrepreneurs in Canada.
The documentary also features an interview with Hermann Scheer, a German parliamentarian who is:
...leading the way to increase Germany's reliance on renewable energy sources such as wind power and solar power. To date, 15% of Germany's energy comes from renewable sources. Scheer estimates that if Germany continues on this course, by 2030 that will be 100%.
