The bar chart provides information of renewable and non renewable sources of energy used for power generation in the United States for the year 2009 and 2019.
Overall coal was the highest and petroleum was the lowest non renewable power generator for the year 2009. Whereas, both saw a decline in the year 2019. In the case of renewable source of energy hydroelectricity was the highest and solar was the lowest power generator for the year 2009. Where hydroelectricity stayed unchanged, solar demand showed an upward movement in the year 2019.
Coal was the highest source of electricity generator at the rate of 1756 billion kw hours in the year 2009 however it declined to 966 billion kw hours in the year 2019. Again petroleum which was the lowest source of power generator at the rate of 57 billion kw hours in 2009 again showed a fall to 40 billion kw hours in the year 2019. However renewables , nuclear and natural who generated electricity at the rate of 437, 799, 921 billion kw hours subsequently in 2009 showed an increase to 720,809,1582 billion kw hours subsequently in the year 2019.
Hydroelectricity was the highest source of renewable source of power generator at the rate of 273 billion kw hours in the year 2009 remained unhinged even in 2019. Meanwhile solar energy and wind energy which were at the rate of 1billion kw hours and 94 kw hours showed an big rise to 73 and 300 billion kw hours. Geothermal energy and plant or animal matter energy which was at the rate of 15 billion kw hours and 54 billion kw hours showed only a little increase in 2019 to just 16 billion and 58 billion kw hours in 2019.
