I don't agree at all. Natural gas is just another fossil fuel, maybe slightly less damaging but still damaging nonetheless, it is more damage on top of an unsustainable level of damage. The only direct energy is sunlight. That is the source which sustains all of nature with no polllution, and it comes to us for free so if you use it you are receiving wealth for nothing. The amount of money needed to kickstart it is a tiny fraction of the wealth spent on weapons, and that would also ensure complete energy independence of your country from any other, so is money spent on actual defence.
Also frackng, why the hell frack when you can have solar.
Further, you can generate perfectly fine money which really does add to the economy using solar, as well as clean hydrogen fuel, and even food with the technology now available. So what are you really waiting for?
