Quote from the article "The problem may intensify with the approaching winter." and "The coming winter can be critical,". The article dates vom october 2012 and the winter is over, no large-scale blackout in europe so far.

Renewable energies require updates to the network infrastructure - granted - but should that be a reason not to push technology and try to improve?

Why would Poland need to update their infrastructure so that Germany can force their excess production upon them.

Do you even understand what you are saying here?

You're reading something I'm not saying. Germany is investing billions in its own networks to handle those issues, for example into 6 new large scale distribution lines from north to south. So yes, we want to change what energy we're using but we're paying the cost. And then, it's not like germany isn't the largest net-payer in the European Union. Certainly a small part of those subsidies could be invested in energy networks in need of technological updates - currently we're already paying to bring old east-block nuclear plants to more modern safety levels, so a couple of cables shouldn't be too much of a big deal.

You are significantly underestimating the cost of high voltage transmission infrastructure.
