The two graphs show the main sources of energy in the USA in the 1980s and the 1990s. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The bar chart illustrates data about the main sources of energy in the USA between 1980 and 1990. Overall, oil remained the dominant source of energy in both decades, although its share declined over time. In contrast, the use of coal and nuclear energy increased, while hydroelectric power became less significant. In the 1980s, oil […]
