The chart represents the amount of electricity generated in the United States between 2009 and 2019 using renewable and non-renewable sources of energy. The units are measured in billion kilowatt-hours.
Overall, in 2009, the major source of energy was generated through coal. Whereas, in 2019, natural gas produced most of the essential electricity in the United States. Meanwhile, when considering the renewable sources of energy, wind and hydroelectricity have contributed to the production of electricity in 2009 and 2019.
A large proportion of electricity was taken from coal, which produced 1,756 billion kilowatt-hours in 2009, and natural gas generated an output of 1,583 billion kilowatt-hours in 2019. However, petroleum made up a relatively small amount of 57 billion kilowatt-hours and 40 billion kilowatt-hours in 2009 and 2019, respectively. Renewable sources like solar and geothermal generated 1 billion kilowatt-hours and 16 billion kilowatt-hours of electricity in 2009 and 2019. On the other hand, hydroelectricity and wind produced 273 and 300 billion kilowatt-hours of energy in 2009 and 2019.
The natural gas and coal have produced a very large quantity of electricity in the United States, in comparison to the other sources of energy in the given time period.
