This point of view is interresting. However, the statement
“The demand for electricity is definitely going to increase by the year 2050 as the use of fossil fuel must be substituted and as of now the only available substitute is electric power.”
is misleading because fossil fuel is a primary source of energy, while electricity is not.
This point is clear in the Figure “Energy by source” in which electricity does not appear.
It is a pity using improper vocabulary in such communication, as well as mixing “power” and “energy”, or “power production” and “electricity production”…
