Two aspects to consider in this matter. On the one hand, the inflation characteristic of fiat currencies. On the other hand, renewable energy technology.
The financial system that wants to continue enslaving people with invented taxes, because why do they collect taxes if they are the owners of the money and can just as easily print more or put more numbers on magnetic cards or checks.
Renewable energy technology does not suit the owners of fossil fuels, who are the same owners of the money.
Therefore, any project that is against those owners is destined to fail.
The slavery of people has not disappeared, it has only changed its form.
