The crucial USA sources of enegry in 1980 and 1990 are shown by the 2 pie charts. Overall, it is clear that 3 largest sources in both years are oil, natural gas and coal. Oil and natural gas proportions had a downward trend, while 3 other datas rised or stayed stable. In 1980 oil and […]
The pie charts below compare the changes in the consumption of five main energy sources (oil, natural gas, coal, hydroelectric power and nuclear power) in the USA in years 1980 and 1990. Overall, oil remained the dominant source of energy in both years, although its share declined, while the contribution of coal and nuclear power […]
The two pie charts illustrate the main sources of energy in the USA in poth periods: 1980s and 1990s. In general, it can be seen that depending on oil as a source of energy declined gradually; on the other hand, the dependance on natural gas did not change observably. According to the data, it is […]
The pie charts illustrate the comparison of proportions on five main sources of energy in the USA in 1980 and 1990. Overall, oil was the most significant source of energy by far in both years. However, oil decreased its dominance in the market, whilst all other sources increased. The three biggest sources of energy in […]
Two pie chart compare some major sources including oil, natural gas, coal, hydroelectric power and nuclear power to provide for mechanical engineering in USA in the 1980s and 1990s. As can be seen, oil accounted for a highest proportion in 1980 and 1990. In contrast, hydroelectric power and nuclear power represented for a small part […]
The pie charts illustrate five main sources of energy in USA over a decade from 1980 to 1990. As transparent from the statistics, the proportion of nuclear power and coal energy witnessed an upward trend, while the opposite was true for oil energy, In addition, the figure for natural gas and hydroelectric power mostly remained […]
The pie chart illustrates where the US got the energy in the 80s and 90s. Oil was the most important source of energy in both decades, but it was used less as did coal Instead they started to use more nuclear energy. According to the data oil was the main source of energy in the […]
The provided charts depict the main energy sources utilized in the USA during the 1980s and 1990s. Overall, in both 1980 and 1990, oil was the primary energy source, with slight fluctuations in its percentage. Coal experienced a notable increase, surpassing natural gas to become the second most prevalent energy source in 1990. Hydroelectric power […]
The two pie charts illustrate, several main sources of energy in America in the 1980s and the 1990s. Overall, oil was the most dominant among all other categories in both years. Only one category remained constant called “hydroelectric power” while, some changes occurred in the others. In 1980 oil was the most popular source of […]
