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 amout of electricity which plumped over the periods and natural gas and renewables came up-front as leading producers in final year, whilst nuclear power usage remained relatively lower.
In 2000, the country generated 180 TWh 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, 20 TWh difference as noticed in 20 years, starting at 70 TWh and going doen to 50 TWh.
On the other hand, natural gas which were producing 90 TWh of electrcity grew drasticaly, to 160 TWh in 2020. In the initial period renewables products a tin fraction of electrical power (20 TWh) that surged dramatically to 170 TWh by the final period.
