I thoroughly agree about the source of future energy, my point was simply that we shouldn't be worrying about what is made where.In reality this is short term thinking. And that's not including the geopolitical high wire that we have to tread with trading 'partners' that include the middle east and Russia.
The black stuff will run out. So lets move on to the truly infinite resources of the sun,wind,tides,hydro. Looking into my back garden, two of them are pumping away right now and they're not running out anytime soon. Why have all the infrastructure when you're own house is its own little power station.
Technology will take us there and i hope none of that development is on a slow go just because oil is still the daddy in the room.
Better battery tech, solar roof tiles, heat pumps etc etc combined with devices power consumption becoming increasingly efficient ......it shouldn't be hard to get everyones house, at best, to neutral status.
And in that sense it has nothing to do with security, economics etc......its just the logical way to proceed.
Everything should be made where it can be most efficiently made and the trade that comes from that will become the security people are after.
