When are people ever going to START doing something?

And yet there is still reluctance for people to jump in and install PV. While that chart is very eye opening, unfortunately it supports my claim that price is not the main motivation to go with solar.
I am hopeful that the connected pv load will increase but it will not become a large percentage of all energy generated.
All you have to do is look at Germany. Solar is maybe 22% while fossil fuel generation is still over 50%.

Yep. They still have a few nuclear plants working. Actually the % of energy from those plants is decreasing and energy from wind is increasing. But their total RE is not enough to run 24/7 so they have been increasing the output of their coal fired plants. Sounds green to me.Comment

You missed the second chart which shows exponential growth in installed solar capacity.Comment

Definitely lots of rose colored glasses in operation... or, as it's called elsewhere, irrational exuberance.
But if indeed manmade climate change is a clear and present danger, per the consensus among climate scientists and economists who publish about climate change, it's only irrational from a short term viewpoint. Germany and California invested early in solar in a big way, and by doing so, helped drive down prices. Expensive, yes, but it moved mountains.Comment

Data is kind of funny. You can't always use one piece (like cost) to justify as being the main reason people purchase things. Although fear can make people shy away from some things or drive them toward something else.
I won't go into what I believe is causing global climate change here because as I have told DanKegal, I choose to be polite even if we disagree.
But for whatever my reasons I would still like to see more solar installed. I just don't want to be bullied into doing so.Last edited by SunEagle; 01-06-2016, 09:45 PM.Comment

And yet there is still only a couple of % of the total power generated in the US coming from solar. So while cost may have some affect on the installs it is still not the main motivator. A lot of solar installs is State mandated for POCO's to have a % of their total energy come from solar or RE. The POCO's were not driven to install because of low cost, they were forced by law.

Demand is obviously very price sensitive since people and businesses like money. The government's SunShot initiative says that utility scale solar will be competitive without subsidy at $1 a watt. First Solar's utility scale costs will be below $1 a watt by 2017, 3 years ahead of the governments goal. Solar is a technology which gets better over time. Very cheap, clean energy will make humanity richer.Comment

Apropos Germany:
they added 1.4 GW of PV in 2015 ( http://strom-report.de/photovoltaik/...stromerzeugung )
and 4GW of wind in 2014 ( http://strom-report.de/windenergie/#...windkraft-2015 )
so they're not standing still.
http://www.solarserver.de/solar-maga...romexport.html says renewable energy handled 27,3 % of their total electrical energy consumption in 2014, and 32,5% in 2015. That's quite a jump for a single year.
(They say kwh from wind jumped 50%; solar only went up 5%.)

10% of the time, but a nuke runs at capacity 90% of the time. No apples to apples there. Wind here runs 22%.

I think I was careful - the latter half of my post quoted actual energy generated, so it compensated already for the capacity factor. That part was indeed apples to apples.Comment

What is sad is they increased the output of their coal fired plants to off set what they lost from their nuclear generation that they closed down. Even with a large increase in Wind they just don't have enough 24/7 based generation to cover when RE is not available. So hopefully while they increase their solar generation they come up with something better then running more fossil fuel.
