How to modernise Europe’s power grids to deal with renewables and increased demand?

How to modernise Europe’s power grids to deal with renewables and increased demand? The technical issues are shockingly complicated and the politics are polarised. This paper from John Springford, of the Centre for European Reform, explains that more European trade in electricity could amp up production and dial down prices. But trading electricity across borders encounters resistance from some national governments: while it lowers prices overall for Europeans, it may raise prices locally. Mr Springford calls for conducting the gains from trade back to consumers so they can see how they benefit.
