41 Finalmente… 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!
