There is an old joke that says Brazil is the country of the future – and always will be. But with rapid economic growth, the government claiming that some 40 million people have been lifted out of poverty in the past decade and the 2014 World Cup and 2016 Olympics in Rio de Janeiro on the horizon, it seems the joke is about to fall flat. Brazil's time has arrived and the country of sun, sea and samba is keen to showcase itself to the world as a positive example of how to exploit renewable energy sources as well as how to perform on the football pitch.
