If 24 Mtoe had been converted into electric power with 30 per cent efficiency, 8 Mtoe could have been exported to the grid which sold 34 Mtoe to end users.

Brazilian ethanol production soared to 12.3 billion litres in 1985-1986 from just 600 million litres in 1975-1976, and about 10 million vehicles were manufactured or adapted for ethanol use.
