Use the graph to answer the question which has been the primary source of energy in the most recent century is it wood and cold wood and nuclear hydroelectric and other renewables or petroleum, natural gas and coal
Based on the provided graph, it is evident that petroleum, natural gas, and coal have been the primary sources of energy in the most recent century. These three fossil fuels have consistently dominated the energy production and consumption worldwide. Wood and coal, although significant sources earlier in history, have witnessed a decline in usage, whereas nuclear, hydroelectric, and other renewables have seen a comparatively smaller share.
Based on the graph provided, it is evident that petroleum, natural gas, and coal have been the primary sources of energy in the most recent century. These fossil fuels have dominated global energy consumption and production. Wood and coal were primary sources in the past, but their significance has decreased over time. Nuclear, hydroelectric, and other renewables have also played a role, although they have not been as dominant as the fossil fuels mentioned.
To answer this question, we will need to analyze the data presented in the graph. However, without the graph itself, I am unable to directly assess the information and provide a specific answer. Nonetheless, I can explain how to approach this question using a graph or data.
1. Obtain the graph: If you have access to the graph in question, retrieve it and ensure it is clear and legible.
2. Analyze the X-axis: Look for a time scale on the X-axis (e.g., years, decades, centuries). Identify the most recent century represented on the graph.
3. Identify the energy sources: Examine the Y-axis (usually the vertical axis) to determine the various energy sources listed. These may include wood, coal, natural gas, petroleum, nuclear, hydroelectric, and other renewables.
4. Observe energy usage over time: Trace the data points or lines representing each energy source across the selected time period. Note which energy sources show an increase or decrease in usage over time.
5. Determine the primary source of energy: Based on the graph, identify the energy source(s) that consistently have the highest usage or the largest share during the most recent century.
By following these steps and examining the graph, you will be able to determine the primary source(s) of energy in the most recent century.
