How is competition compatible with environmental goals?
How is competition compatible with security of supply goals?

1) It is not.
2) It is NOT.

One thing has to be stated loud and clear, once and for all.

The goals of EC have nothing to do with the energy security. They have much less to do with that ridiculous idea of "saving the environment". All they have to do is with enriching certain set of entities who are watering just at the thought of acquiring the portions of utilities and the grid about to be "privatised". What can be better for these maruadeurs than replacing 1-2 well regulated monopolies with dozens of unregulated, unaccountable regional monopolies??? The user be damned, let him pay until and get polluted until he drops dead.

Capitalistic mother-f****s.

Agreed.

And don't forget the investment banks who get to make money on hedging price volatility which used to be absorbed by natural monopolies able to price electricity at average price + (fatter) margin instead of marginal cost + thin margin.

The irony, of course, is that the biggest winner of all these games is EDF and its owners, i.e. mostly the French government.
