The total energy use in 2013 was 157 000 TWh (and it's probably <<much, much>> higher in 2021, due to China and India continuing to develop).
The additional solar power being added in 2061, by your own math, is 154 TWh.
So, adding up the whole line, that would mean that solar would still only offer about 154 x 40 = ~6 000 TWh (best case scenario) of electricity in 2061. Faaar from the 157 000 TWh used in 2013 and probably super far from what's going to be required in 2061.
