[E. Pluribus Unum]

That's why they don't want viable energy source of any kind.

Cheap energy = prosperity for the masses

Expensive energy = poverty and death for the masses

"Green" energy takes more energy to produce than you get back out of it. Wind energy is hundreds of times more expensive than 'fossil' energy.

[Sir Napsalot]

>>> That’s why they don’t want viable energy source of any kind.

You could substitute a lot of things with ‘viable energey source’ in this quote. For example,

That is why they don’t want a well armed and well educated populace for self governance,

That is why they don’t want a true capitalism of any kind, that has shown the best model to promote well being and liberty,

etc. you get the idea.
