I think you are not far wrong here :) you got close imho, when you mentioned using solar to assist bamboo growth, but you were spot on to notice much of the renewables industry, if not all of it is just-for-profit bullshit, if I've interpreted correctly.
Keep thrashing, the whole truth will be flailed out soon enough, it seems to me :)
You might like some of the stories in my profile too, I write about this stuff a lot. It is good to exchange views, I think.
