Rising energy prices should have an impact on global GDP growth in 2021, though the ratio has been declining. Over the past 20 years, expenditures on energy and global GDP have an R2 of 0.873, but the share of energy to GDP has been declining. Splitting the two attributes on separate axis in the graph below enables a display but distorts this relationship.
