My question was and I'll repeat, how many billions will it cost to make their use worthwhile?
Let me give you an example.
The energy projects under CPEC will cost Pakistan more than $30 billion.
Now, where will Pakistan get that sort of money (on top of CPEC) to launch more large scale energy projects that could make Pakistan an energy independent nation?
Its okay to envision all these things but they will easily cost tens of billions of dollars. The money needed for these visions, Pakistan simply does not have nor it can easily get from anywhere. CPEC being the only one exception since the 1960s.
And don't forget, as soon as Pakistan got CPEC in 2013, FATF was launched in 2018 just to make sure Pakistan does not develop too fast or becomes too independent.
