The charts provided illustrate the production of electrical power from renewable and non-renewable resources in the United States for the years 2009 and 2019. The figures are measured in billion kilowatt hours.
Overall, it is evident that electricity generation significantly relied on coal in 2009, but this dependence decreased over the following decade. Conversely, the generation of electrical energy from renewable resources, which was less popular in 2009, saw an increase over the ten-year period.
As shown in the first graph, coal was the most popular source of electricity production in 2009, generating 1,756 billion kWh. However, this amount dropped to 966 billion kWh by 2019. During the same ten-year period, the use of natural gas and renewable resources for power generation expanded to 1,552 billion kWh and 720 billion kWh, respectively. There was only a slight change in the usage of nuclear and petroleum resources.
In 2009, wind energy generated 94 billion kWh, which increased to 300 billion kWh in 2019. Solar energy production rose from 1 billion kWh in 2009 to 73 billion kWh in 2019. There were minimal changes in the output from geothermal and plant and animal matter resources. Throughout the decade, the production of electrical energy from hydroelectric sources remained stable, consistently at 273 billion kWh.
