▶ Your Answer : The line chart compares the quantities in quadrillion units from energy consumption for six different fuels, namely petrol and oil, coal, natural gas, nuclear, solar/wind, and hydropower, of the America from 1980 to 2030. It is clear that consumptions of fuels for five out of the six types rise, leading to a obvious rise in total spending energy. Units number of petrol and oil is the most popular thing every year. In 1980, United State consumptions of nuclear, solar/wind, and hydropower started at around 3.5 quadrillion, but petrol and oil was spent about 35 quadrillion. The figures for consumptions for coal and natural gas were at least three times as much as those for the lowest things in that year. In every years, the amount of energy for using petrol and oil and coal increase gradually, while consumptinos of the others do not nearly change. In the year 2030, consumptions of petrol and oil and coal is expected to reach peaks of 50 and 30 quadrillion units respectively. By contrast, the gap of three types(nuclear, solar/wind, and hydropower) is predicted to remain unchanged from 2010 to 2030. |
