PennWell publishers Marla Barnes and Michael Grossman recently sat down with José da Costa Carvalho Neto, president of Eletrobras, in his office in Rio de Janeiro, Brazil, to learn more about this company and its ambitions for the future.

Hydropower is the world's largest source of renewable energy. In Latin America, it is the main source of power generation, accounting for roughly 65 percent of all electricity generated.

Wind power is poised to play a greater role in meeting Latin America's growing demand for electricity. Brazil, Chile and Mexico are expected to have added more than 3.7 GW of wind power from 2010 through the end of 2012, according to a study from IHS Emerging Energy Research (EER).

Latin America, where electricity demand is projected to grow more than 4 percent a year over the next decade, will require huge investments in new power generation to meet the demand of surging populations.
