Small country, big challenge: Switzerland’s upcoming transition to sustainable energy

Switzerland has long met a good portion of its energy needs by using nuclear power. But in the wake of the accident at Fukushima, the country will have to turn elsewhere—while still remaining true to its history of self-sufficiency and energy independence. This effort is made more complicated by fears that one of its traditional energy sources, hydropower, may no longer be as reliable as in the past. But with a combination of energy conservation, greater efficiencies, alternative energy sources, the "smart grid," and the introduction of new technologies currently on the drawing board, the country may readily be able to replace the energy lost by the closing of its existing nuclear power plants. And the loss of the snowpack and glaciers (due to climate change) may not be as dire for Switzerland’s hydropower as first anticipated.
