The government must take the lead. Government own project, there many land in Pakistan that can be used. Government invites foreign investors to invest in the solar panel industry and make a deal with certain project from government that will make them see the investment as profitable. Any way, the labor cost in Pakistan is also cheaper than in many countries.
EV industry infrastructure also must be set up, step by step. So hopefully electricity will use renewable and the cars and motor cyles will not use imported oil any more
