The line graph illustrates an information from an account in 2008 regarding to the usage of two types of energy which are fossil fuels (petrol and oil, coal, natural gas, nuclear) and non-fossil energy sources (solar/wind and hydropower) in North America since 1980 and the predictions up to 2030. Units are measured in quadrillion units (QU).
Overall, there will be expected to a gradual increase in both kinds of fuels. It is evident that the use of the non-renewable energy source have been climbing significantly as opposed to the renewable resources.
By 1980, petrol and oil stood as the most consumed energy sources, starting at roughly 35 QU. The consumption increased steadily, surpassing 40 QU by 2005 and is projected to exceed 50 QU by 2030. Similarly, coal and natural gas followed an upward trajectory, with coal usage overtaking natural gas around 2015 and expected to surpass 30 QU by 2030, while natural gas remaining below 10 quadrillion units.
At the beginning of the timeline, nuclear, solar/wind, and hydropower were utilized significantly less than fossil fuels, each remaining under 5 QU. Nuclear energy experienced a gradual increase, reaching approximately 8 QU by 2010, with a steady upward trend projected. In contrast, solar/wind and hydropower witnessed minimal fluctuations, remaining below 5 QU throughout the period.
