The situation we're in is a complete failure of energy policy. Anyone involved in energy planning for this country should hang their heads in shame. Total failure to be in this position.
Also, France isn't "shielded" from the price increase. EDF still has to buy energy on the market, it's being prevented from recouping those costs. It's making huge losses (5Bn euros in the first half of the year, projected 30Bn for the year, more next year). All this money just comes from taxpayers.
Most countries in northern Europe in particular are exposed like we are - Germany particularly so, just with a slightly greater lag time.
Now, we're slightly extra fucked for a couple of reasons. No gas storage, and betting the farm on gas for our electric base load (rather than say, nuclear).
The best options I can see would be to soften the impact for the next year or two, whilst preserving the price signal - i.e. we can't obscure these higher prices completely from consumers.
In the meantime, we go hell for leather for energy self sufficiency. Bring fracking online now, lower the planning bar for solar / wind and hurry the fuck up with our various nuclear projects.
