I am certain that the United States next year, under a new president - regardless whether it's Obama or McCain - will present an ambitious program promoting renewable energies and energy efficiency. Europe could quickly fall behind.

The shadow of an exit of Greece from the euro zone takes on ever clearer shape, repeated apparently final attempts to reach a deal are starting to make the whole process look ridiculous. There is an ever greater number of people who feel as if the Greek government is giving them the run-around.

Besides Germany, the only countries that don't have speed limits are places like Nepal, where road conditions are so bad that a limit would be beside the point. In other words, it's a little crazy that this is even a topic for debate in Germany.

A major danger for us Europeans: We must demonstrate that those who have this view of us are mistaken, that we can come to agreement, that we as a community of democratic and free nations are economically successful and are gaining political influence. To do so, we must learn to project our power.

I'm hearing different things, but there is concern that stable Germany is no longer quite so stable.

The claim that democracy and efficiency are contradictory is nonsense. That's evident in the history of democracy itself, because it is only democrats who were and continue to be capable of learning from mistakes. A more appropriate question is to ask whether a country like China, which has been so incredibly successful economically, is actually inefficient in light of its environmental destruction and its corruption. In China's perception, however, the democratic model is doubtlessly inferior.

We need a greening of globalisation.
