It is. They tend to do it on a scenario basis, so they have different scenarios to allow for an understanding. That's why I referenced, in this most optimistic scenario, that hydrocarbons will remain at 47% of the energy mix.
Other scenarios, which suggest that renewables and reduced consumption of hydrocarbons would lead to lower emission profiles and higher use of renewables and other forms of non-emitting energy, also continue to grow, but even in the most optimistic scenario, 47% would still be the share of fossil fuels by 2035.
Where they tend to see a huge difference is with coal. Coal tends to be the one area in which you see a lot of variation. To the extent that non-emitting forms of energy enter the mix, they tend to offset the coal, but overall demand for energy continues to grow, so the rate of growth is smaller than it has been.
