So, as happened with Mobiles, before you know it Solar PV will proliferate

Solar power will be cheaper than Grid power within next decade. You and me will be power producers at our homes.

When solar PV prices crashes to 25% of what it is today (as predicted by 2020), you'd be able to get 100% of your electricity with about US$5000 and the ROI will come down to 2.5years after which you'll have years of free electricity. Almost every one will adopt it.

Future will be far different than what we see today.
