Calling something a religion is a lazy and disingenuous way to dismiss it. The effects of airborne and waterborne pollution on human health has been the focus of scientific investigation for centuries at least. Ecosystem destruction is not "a religious belief" - it's something which has been measured, carefully recorded and studied using scientific methods.

> at 1/1000th the cost of re-wiring our entire energy system around renewables

This is alarmist hyperbole. Renewables now account for about 35% of the global electricity generation mix. There are countless examples of countries that run grids where renewables account for more than 80% of the electricity mix. Even if you just consider wind and solar, many countries are approaching 50% penetration in the space of 20 or 25 years without "re-wiring their entire their entire energy systems".

Yes NG generation is the only fossil tech still standing in terms of being able to compete at any level with modern generation tech but it is being squeezed. Batteries surpassed NG in terms of economics for peaking sometime around 2020/2021 - which is reflected by the share of new capacity investment since then.
