A great case study is to look at the Energiewende program in Germany. The switch to a fully renewable energy economy resulted in such a surplus of energy, the resulting market price of energy collapsed. The response, is now to build massive coal and gas plants, which a significant chunk will be supplied by Russia. Their carbon footprint, will soon exceed their 1990 footprint, when they decided to switch to renewables. On top of that, they need to build an additional 60,000 windmills, resulting in an even greater overcapacity. Their heart was in the right place, but it is a complete and total failure. Now they are trying to export as much emissions as possible to save face.

Imagine if Airbus developed an aircraft that didn't run on gas, but some alternative energy. The only catch is the aircraft has 60% dispatch reliability. It's not hard to see that this aircraft would immediately bankrupt every airline that purchased it.
