Italy's Prime Minister Matteo Renzi and the chief of Enel SpA took time out of a visit to Malta in April to discuss a matter of national importance: how to use the state-controlled utility's pipes and pylons to help get high-speed Internet to all Italian homes. Renzi had long wanted Telecom Italia to cable the country for super-fast Internet to get Italy's digital reach up to speed with the rest of Europe and help kick-start a suffering economy.
