The problem with photovoltaics is that they are black so they absorb a lot of light from the sun instead of reflecting it back to space as would happen if your roof was painted white instead of photovoltaic black. So we have global warming looming from the increasing black surfaces. I'm chuckling here Bud, at the Global Alarmists inadvertently heating the air when they thought they were being Green.

I'm the one chuckling bud..

The vast majority of PV's manufactured have a blue tint to them, not black. You need to get out there and really work with this stuff!

Your ignorance is showing.

If 7 billion people and their industries get all their electricity from photovoltaics, the heating will be huge. And worse, the heating will continue whether the electricity is wanted or not though presumably storage methods will be developed to absorb all the spare electricity at peak times.

More ignorance on your part.

The vast majority of PV's are grid connected and all of their electricity is absorbed by that grid in real time!

Have you calculated the net global warming if everyone gets their energy from photovoltaics?

We have many times in the past and it's not a net global warmer like fossil fuel burning is.

A fraction.

Go back to school and learn how this stuff really works.

Or better yet, get out in the field and build some systems and measure their performance.

You will learn a lot more that way instead of reading some right wing blogs by morons with no experience in photovoltaics.
