The bar graph illustrates the records of electricity generated, in terawatt-hours, from four distinct sources in a nation in 2000, 2010, and 2020.

Overall, coal was used to generate the most amount of electricity, which plummeted over the periods, and natural gas and renewables came to the forefront as leading producers in the final year, whilst nuclear power usage remained relatively lower.

In 2000, the country generated 180 TWh of electricity using coal, which was the highest recorded amount in all the years; it declined to 150 TWh in 2010 and fell significantly to 60 TWh by 2020. Nuclear power usage fell gradually, with a 20 TWh difference noticed over 20 years, starting at 70 TWh and going down to 50 TWh.

On the other hand, natural gas, which was producing 90 TWh of electricity, grew drastically to 160 TWh in 2020. In the initial period, renewables produced a tiny fraction of electrical power (20 TWh) that surged dramatically to 170 TWh by the final period.
