Which is most attractive?

All systems of generating and distributing electricity will potentially be of equal interest to those of us involved with the global wire & cable industry, but in the words of George Orwell, “some are more equal than others”, based on either intensity of use, sheer volume of installations, barriers to entry, including governmental support, or of course, all three. This means it should be possible to rank segments of the renewables market in terms of attractiveness to wire & cable suppliers over the next few years.
