The global demands for transport are changing, and there is an increasing shift toward reducing greenhouse gas emissions by adopting alternative clean-energy sources.
The graph shows the change in total road transport energy consumption and the consumption from fossil fuels between 2010 and 2030, alongside projections up to 2060.
Total road transport energy consumption is the sum of fossil-fuel road transport energy and clean road transport energy (such as electric vehicles powered by renewables).
Describe the change in the consumption of fossil-fuel energy and the consumption of clean energy between 2010 and 2030.
