Such an important and timely topic. The big question I have: are we going to have enough of a 'memory' to use this as motivation to actually change? It hasn't happened sufficiently in the past, but perhaps now it's happening at the right time that technologies and markets can respond. 

I was immediately struck by how counterproductive "Energy Sanctions"  would be, and we've predictably seen blowback. My own country, the UK, has been particularly short-sighted in its energy policy: cancelling the first Tidal Lagoon, banning onshore wind, and downsizing natural gas storage, which seemed to me to be ill-thought-out. At the top level, most politicians seem incapable of rational decision making, which makes this crisis worse.
 

I've come round to thinking that some sort of small, modular nuclear power (possibly thorium/molten salt reactors) will be needed to cover the load management gap between renewables and baseload power. It would also add to energy security.
