The line chart illustrates information regarding the used amount of renewable energy in the USA over the 60-year period. Overall, it can be seen the consumption of eco friendly energy witnessed a gradual upward with a moderate fluctuation during the period. Additionally, the appearance of new energy from 1980.
In 1949, the quantity of wood consumption was nearly 1. 8 quadrillion Btu and maintained the same level until 1975, before rising significantly and reached its peak in 1985. For the next 10 years, the figure of wood slightly decreased and was around 2 quadrillion Btu at the end. Meanwhile, starting with the same level as the consumption of wood, that of hydroelectric power increased gradually until 1975 and then through many years of oscillation, this figure was approximately 2 quadrillion Btu.
Interestingly, biofuels and wind were first released in 1989 and reached up to around 1 and 0. 5 quadrillion Btu respectively at the end of period.
