The supplied table reveals the electricity generated from coal, natural gas, oil, nuclear, and renewables in 2000 and 2020.
Overall, the amount of electricity generated varied considerably across the energy sources in 2000 and 2020. Electricity generated from coal accounted for the largest proportion, yet decreased significantly to let natural gas take the lead. In contrast, renewable sources represented the smallest share in 2000, and in 2020, nuclear sources. The remaining sources stood at intermediate positions.
After meticulous consideration, coal stood at 42% as the leading source in 2000, yet experienced a fundamental downward move. Meanwhile, oil slightly decreased to 15%. By contrast, natural gas increased its share in electricity generation from 22% to 30%, becoming the leading source in 2020. Also, nuclear sources stood at 10% and experienced a similar pattern, reaching 12%. In 2000, renewable sources occupied the last position but, by 2020, underwent a considerable shift of 10% to account for 18%. At the end of the period, nuclear made up the smallest proportion at only 12%.
