Musket, as usually you are way off. Blatant liars for financial reasons are a fact of life, and they have become more unashamed in recent decades. Building up a good reputation is no longer considered a good business idea.

Cheap and large-scale renewable energy is an established reality, e.g. in Germany, where I live. (Electricity is still expensive for ordinary users who do not own a roof with a solar panel, but that is political.) Suppliers keep complaining and predicting the collapse of German and European economy, of course, as they did before.

Compressed air is the topic of the OP, not my personal best bet.
