Which type of energy source would you prefer to see installed the most?

Of the available options, wind is the one I like least.  There is a notable problem with the killing of birds and bats. The best places for generating wind power are generally far from where power is needed.  And last but not least, wind power is so unreliable that even when built, you still have to build the other generating capacity you would have built if you'd never built the windmill. Can be useful if used for applications where intermittent power is acceptable and in some remote high latitude locations where solar power is less reliable than wind for year-round power, but those are not common.

I have always had a soft spot for nuclear energy. Too bad most of my fellow citizens and my government disagree because of the severe incident in Japan.

Which is a shame.  Granted, nothing is ever foolproof, but known and preventable foolishness at both Fukushima and Chernobyl led to the resulting deaths and damage.  Not only that, but both plants were outmoded and would never have been approved for construction in any competent jurisdiction as of the day before the accidents took place.  So the Kernkraftwerk Niederamt wouldn't have been affected by them.  Besides, if a tsumani ever hits Switzerland, your country will have more serious problems than what happens at its nuclear reactors.
