education: “It must be explained to people that the
overall result is very, very positive. Hydropower is
the most sustainable form of electricity generation.”
This is because the stations have a very long
lifespan. Moreover, hydropower is the cheapest means
of generating electricity. It is also slowly being recognized
internationally that wind power and hydropower
complement each other and should be developed in
parallel. “This is precisely what EDP realized seven
years ago,” says Riesterer.
Obviously, the descendants of the sailors still have a
water-related spirit of discovery today.
