The graphs compare the production of electricity through various conventional and non-conventional sources of energy in the United States over a decade.
Overall, the use of wind as a renewable source almost tripled its energy generation as time passed. In 2009, coal generated the most energy as a non-renewable source, accounting for 1,756 billion kilowatt-hours, the highest in any category even in 10 years. However, by 2019, its production had decreased.
In the year 2019, the most energy-creating substance was natural gas, measuring 1,582 billion kilowatt-hours. This was seen as a significant increase from 921 in 2009. Electricity generated from petroleum and nuclear sources more or less remained the same, with a decrease in the former and an increase in production due to nuclear power.
The renewables bar graph shows a massive increase in electricity production from solar energy, once accounting for only a billion and now a ground-breaking 73 billion kilowatt-hours of energy in the recent year. This, along with wind power, might have made a difference in the total amount of renewables, increasing from 437 to 720. Another notable renewable has been hydropower, which has remained the same over the period.
