Austria gets over 60 percent of its electricity from hydropower, compared with a world average of 16 percent. But climate change is disrupting things. "In the future, the amount of water available will remain the same, but its distribution over the year will change," explains Klaus Hebenstreit, an executive at state-owned Verbund, the country's main electricity producer. "We'll have less water in summer and more in winter", he says. But the country is forging ahead with hydropower infrastructure, constructing a new pumped-storage hydroelectricity station in the mountains above Salzburg. IMAGES AND SOUNDBITES
