It is noticeable that the amount of oil-consuming decreased and that of hydroelectric power still maintained. By contrast, there was a significant growth in the amount of coal and nuclear power using as one of the main sources.</p><br style="color: rgba(0, 0, 0, 0.8); font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", "Helvetica Neue", sans-serif; font-size: 16px; white-space: normal; background-color: rgb(249, 249, 249);"><p style="margin-bottom: 1rem; color: rgba(0, 0, 0, 0.8); font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", "Helvetica Neue", sans-serif; font-size: 16px; white-space: normal; background-color: rgb(249, 249, 249);">Oil consumption accounted for 42% in 1980. Despite its dramatic decreasing to 33%, oil was still has a good proportion in 1990. The percentage of natural gas-consuming also saw a slight decline but only decreased from 26% to 25%. That of hydroelectric power remained at 5% after ten years.</p><br style="color: rgba(0, 0, 0, 0.8); font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", "Helvetica Neue", sans-serif; font-size: 16px; white-space: normal; background-color: rgb(249, 249, 249);"><p style="margin-bottom: 1rem; color: rgba(0, 0, 0, 0.8); font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", "Helvetica Neue", sans-serif; font-size: 16px; white-space: normal; background-color: rgb(249, 249, 249);">On the other hand, the proportion of using nuclear power was similar to the percentage of hydroelectric power in 1980, at exactly 5 percent. This then made up about 10% in 1990 while the rate of coal-using grew from almost a fifth to just under a third.</p>
