Pearson Correlation

Pearson Correlation 

The correlation between the income per person and electricity consumption per person reveal the Pearson Correlation Coefficient r=0.65164, therefore it means that it has a positve relationship and like this value is not close to 1, that is no strong relationship and p-value<0.001 indicates that is enough significatly.
The r2=0.4246 means that we can predict 42.46% of the variability in the rate electricity per person.
The same way the correlation between the income per person and oil consumption per person reveal the Pearson Correlation Coefficient r=0.54189, therefore it means that it has a positve relationship
