The line graphs illustrate the number of energy units produced and consumed in America from 1950 to 2000, with the projection for 2025.
In general, significant increases were witnessed in both the amount of energy used and produced in the US from 1950 to 2000. Meanwhile, as the two mentioned figures went up at different rates, the gap between the consumption and prodcution has became more significant over the preiod. In addition, this trend is projected to countinue until 2025.
To specify, in 1950, the rate of energy production in America was around 25 units per year. Meanwhile, the energy consumption in the same year was around 35 units. Furthermore, significant increases were recorded in both the use and the production of energy in 1975. However, the difference between these two figures, which resulted in the amount of enegry imported, remained unchanged at about 5 units per year. However, from 1975 to 2000, energy use in the US nearly doubled, rising from 60 to almost 100 units per year. On the contrary, the number of energy units produced during the same perioed flutuated heavily. Consequently, since 1975, the rate of increase of engery consumption has exceeded that of energy production. Regarding, projections for 2025, it is estimated that the current trend, in which energy production can not keep up with the pace of increase of energy comsumption, will be continued. Moreover, until 2015, a sustainable rise will be recorded in US’s energy consumption, while the amount of enegry produced will only experiecne a slight increase.
