"In the business of politics, emotions and productive dissatisfaction with the world in which we live..." — Sigmar Gabriel

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.

Climate protection creates sustainability and jobs in the real economy - in construction, in the production of heavy machinery and in systems engineering.

However, I have a low opinion of people with narrow political horizons. Someone who talks about the environment and knows nothing about economics can make as many mistakes as someone who does the opposite.

What we have at present is a system of loss socialism. Whatever goes wrong is shouldered by the general public and anything that works is privatised. Worshippers of market freedom have suspended the most important economic principle: Risk and liability go hand in hand.
