Faced with accelerating climate change and species extinction caused by our own activity, we now race to prevent a catastrophe. And how do we propose to run the race? By changing our running shoes, instead of our pacing. Replace coal with natural gas and then replace that with solar energy. Sounds ok - but it really isn’t.
Anyone with even a passing knowledge of the most basic law of the Universe - it being the Second Law of Thermodynamics - understands that creating and maintaining order requires the constant input of energy. The higher the order, the complexity of the system being created and maintained, the higher the amount of energy required.
The easiest way to express this is that a hot object will always cool unless it is heated by an external source of energy. There is no such thing as a free lunch.
