Berlin would benefit greatly from offshore oil and/or natural gas drilling platforms as it is beside the sea and transport between the platforms and the city is relatively short due to the coastal location it lies on. Eclipse would have to build any drilling platforms on land and quite a distance away from the city due to pollution and other factors which would drive up the costs of doing this reducing the profits and growth this would offer in comparison to Berlin. Eclipse however would then have to choose wind as this is the better option as it would give better growth than it would to Berlin as it would be very cheap for Eclipse to work with.
Edit: I focused on Berlin and never mentioned Eclipse.....
