Question

the graph below shows the global use of fossil fuels and other energy resources every year from 1965 to 2015. global energy use per year fossil fuels other resources data sources: our world in data and bp statistical review of world energy use the data to complete the statement. between 1965 and 2015, people obtained of their energy from fossil fuels. at least four - fifths about one - fifth

Explanation:

Step1: Analyze the graph

Observe the proportion of fossil fuels (orange part) in the total energy use (sum of orange and blue parts) over the years from 1965 - 2015.

Step2: Estimate the proportion

Looking at the graph, the orange part (fossil fuels) is much larger than the blue part (other resources). Four - fifths is \( \frac{4}{5}=0.8\) and one - fifth is \( \frac{1}{5} = 0.2\). The fossil fuel part is more than \(0.8\) of the total energy use.

Answer:

at least four - fifths
