Use the graph to answer the question.

The vertical axis ranges from 0 to 100 in increments of 10. The horizontal axis lists dates from 1776 to 2018. The data is as follows. 1776: Wood, 100%. 1801: Wood, 100%. 1826: Wood, 100%. 1851: Wood, 90%. Coal, 10%. 1876: Wood, 65%. Coal, 34%. Petroleum, 1%. 1901: Wood, 20%. Coal, 61%. Petroleum, 3%. Natural gas, 3%. Hydroelectric, 3%. 1926: Wood, 5%. Coal, 65%. Petroleum, 20%. Natural gas, 7%. Hydroelectric, 3%. 1951: Wood, 2%. Coal, 38%. Petroleum, 40%. Natural gas, 16%. Hydroelectric, 4%. 1976: Wood, 20%. Petroleum, 45%. Natural gas, 29%. Nuclear, 2%. Hydroelectric, 4%. 2001: Coal, 25%. Petroleum, 35%. Natural gas, 20%. Nuclear, 18%. Hydroelectric, 1%. Other renewable, 1%. 2018: Coal, 15%. Petroleum, 35%. Natural gas, 30%. Nuclear, 12%. Hydroelectric, 1%. Other renewable, 7%. The values used in the description are approximate.

Thank you for confirming!

To answer the question, we need to look at the most recent data on the graph, which is the year 2018. According to the data, in 2018, the primary sources of energy were Coal (15%), Petroleum (35%), Natural Gas (30%), Nuclear (12%), and Other renewables (7%). Therefore, the primary sources of energy in the most recent century are Petroleum, Natural Gas, and Coal.
