Note that the figures on the graph show the percentages of each fuel used to generate electricity.
The slide title is true, but misleading; coal’s share declines, but actual coal usage is forecast to increase by over 15% from 2008 to 2035. Natural gas increases by almost 25%. Nukes only increase by 11%, and that assumes a 20-year extension (to 60 years) on the certification of existing plants.
Slide 21 shows the detail of the “Renewable” slice.
