Young-earth creationists should be making efforts to end the use of fossil fuels.
If the Flood is responsible for what geologists call the Cretaceous-Paleogene extinction, then it is the probable source of the large coal and oil deposits humans have been mining aggressively since the Industrial Revolution began.
At the end of the Flood narrative, God promises to never destroy all life again by a flood, or by any other means.
Given that, there will never again be such a massive injection of biomass into the processes that generate coal and oil.
As such, the metaphor of Earth as a carbon-based battery still applies, even if not for the reasons put forth in that paper.
If young-earth creationists want modern technology once the oil and coal supplies run out, they should be aggressively pushing for renewable energy sources. Once we're out of gas, we will no longer have the cheap energy to do the grunt work of changing over to renewable energy sources. That process could be done without power tools, but it would take several orders of magnitude more time and human effort.
A brief summary from the worldview's frame of reference:
God filled the gas tank then said that was it.
When it's gone, it's gone.
We should use what's left to stop using it.
