Very relevant.
The green facists keep going on about inaccuracies, notably the life span and efficiency of solar panels.
Whether a solar panel is 8% or 20% efficient, degrades .5% or 1% per year or lasts 25 years as compared to 10 years, IT MAKES NO DIFFERENCE AS TO THEIR VIABILITY. Without government subsidies, no one in their right mind would buy these things.
In fact, the documentary could have spent a lot of time discussing how wind turbines and solar mirrors kill thousands of birds.
It was not even mentioned.
