It will happen. It's going be impossible to get the building permission 
for new nuclear and coal plants. By the time the prices go up, it's 
already too late (I assume it would take another 10 years or so build 
the capacity with traditional technology again).

It's ok as far as I know. Yes, every technology has its drawbacks (short 
of saving energy).

Not much except for the converters that need replacing once in a while.

Yes, absolutely. See my other e-mail regarding the available roof space 
in Switzerland. Even if we use all the roofs that are suitable, we're 
not getting anywhere near enough to supply the country. So yes, 
alternative energy sources will compete with other demands (agriculture, 
tourism, etc.).
