Well Dom, maybe a meager energy world means that some of that flexibility will be lost.

Or maybe it means that "precautionary" societies obsessed to the point of morbid fear by their own shadows, societies that among other things foolishly seek to "decommission" their only short term options, including nuclear power, societies that choose to ignore questions of supply, will simply become miserable backwaters self-consigned to the dustbin of history. Or maybe, more optimistically, when the effects of that sort of nonsensical rubbish really start to bite hard, the people of these fear-ridden societies will finally face up to the hard reality that life is a balancing act, so that seeking the absolute zero of risk and change - including but not limited to climate change and risk attached thereto - might not be the sole and exclusive factor in that balance.
