Industries need electricity to convert
The conversion of all machinery to electric devices will require more electricity from power plants.
Corporations may have to invest in joint-venture power plants running on renewable energy, in case of underfunded power plants. Such investing would require electrical monopolies to be broken, and competition to be able to connect to the existing grid.
The same electrical grid may have to be beefed-up in order to face such an increase of electricity to be transmitted.
