- Não é fácil dar resposta a uma questão muito
complexa como é o futuro dos combustíveis no
setor do transporte. - Muitos avanços técnicos são ainda necessários e
muitas mudanças sociais, políticas e ambientais - No futuro os combustíveis podem ser muitos, mas o
petróleo vai dominar ainda por várias décadas - MUITO OBRIGADO PELA SUA ATENÇÃO!
