The image displays two bar graphs representing US electricity generation. The first graph shows an increase in electricity generation by Natural Gas from 837 in 2009 to 1,582 in 2019 and by Renewables from 437 in 2009 to 720 in 2019, a decrease in Coal from 1,755 in 2009 to 966 in 2019, and relatively stable figures for Nuclear energy at 899 in 2009 and 921 in 2019, with a slight decrease in Petroleum from 57 in 2009 to 40 in 2019. The second graph focuses on renewables only, depicting increments in Wind generation from 73 in 2009 to 300 in 2019 and Solar from 2 in 2009 to 94 in 2019, constant Hydropower at 273 for both years, and a decrease in Geothermal from 16 in 2009 to 15 in 2019, with Plant/Animal Matter staying consistent at 54 for both years.

The bar charts show statistics about the generation of electricity over a period of ten years in the United States, from 2009 to 2019. One of the most noticeable features is the decrease in the use of coal and increase in the use of natural gas and renewable energy sources.
The amount of coal used to generate electricity dramatically declined from 1756 billion kilowattt-hours in 2009 to 966 billion kilowatt-hours in 2019. In contrast, the numbers for natural gas rose from 921 to 1582 billion kilowatt-hours, while renewable electricity generation increased by over one and a half times in the same period.
The second chart shows the changes in different sources of renewable energy used, and the most significant increases were for solar and wind energy. The use of wind energy more than tripled to stand at 300 billion kilowatt-hours in 2019, whereas solar use jumped from 1 billion in 2009 to 73 billion kilowatt- hours in 2019. Other sources, such as hydroelectric and geothermal energy, remained relatively stable over the period.
