 ** For the warm rooms example ** we have already shown that in a practical way on the page about [[basics:energy_efficiency_-_the_key_to_future_energy_supply|basic examples for energy efficiency]]: it is only necessary to use established components for any modernisation of building elements in existing houses which are required anyway.  Specifically:  if a window has to be renewed, triple low-e glazing  should be used for the new window – it pays back very fast, improves comfort and reduces heat losses through the window by a factor of 4.  That is optimal climate protection which is also microeconomically beneficial and creates jobs.\\

The advantage for the national economy lies in the cost savings for the consumers.  The money thus saved can be used for other purposes, e.g. for a bicycle tour in one of our beautiful valleys...\\

-{{:picopen:1-l-auto.jpg?100 }} **And with automobiles ** it can be just as simple, but first manufacturers will have to speed up their model policy.  Germany is about to lose its international leading position in the automobile sector.  Who wants to drive cumbersome petrol-consuming, cost-intensive and environment-polluting vehicles for which one cannot even find any parking spaces? It won't be possible to sell this to people as the ultimate means of self-projection for much longer. The Japanese and other new companies appearing on the market have shown that it is possible to build car models today which are lighter, more efficient, streamlined, quieter and more environmentally friendly.  Within a decade the automobile fleet can be replaced completely with much more efficient vehicles.  Consumers will be sure to pay attention to that with every new purchase, even if it's only to avoid the meaningless depletion of their disposable income.\\

Germany is about to lose its international leading position in the automobile sector((This was written in 2010 and I am not proud to have been correct in this assessment. The big German car companies acted too late and even engaged in dubious activities to avoid paradigm change. Now we can only hope that the change for more sustainable cars will be fast enough to save the future of these companies.)).  Who wants to drive cumbersome petrol-consuming, cost-intensive and environment-polluting vehicles for which one cannot even find any parking spaces?

 ** All this sounds so simple – and it is simple too! **  What is necessary is the serious desire to solve the problem and separate oneself from old, long since refuted and superstitious views:
