There was a significant drop in the quantity oil produced in the USA from 42 per cent to 33 per cent in the between the 1980s and the 1990s. Whereas, the opposite trend was experienced by the proportion of coal, which was 22 per cent at the beginning of the period then grew moderately by 5 percent, overtaking natural gas 20 years later.
