A: Yes, and wind. Wind has a reasonably good energy ROI, but it's not possible to collect enough energy from it without covering the country in turbines, and people don't want that. Offshore is interesting, but the costs (financial and energy invested in building them) are much higher.
B: Market at work, sure, but the end result is the same: They are claiming low CO2 by simply sending the CO2 to China.
C: It is true - look it up if you like. It takes about 20 years to return the energy (forget about the money). And when you have: "the skies are often gray and his roofs aren't all optimally oriented" then those solar cells will never return their energy investment (they will degrade before they are able to do that). Germany is spending money to increase CO2 emissions - brilliant plan: waste money, increase CO2.
> Particularly considering technological progress, this will soon be even more laughable.
You make me laugh. People have been researching solar for decades, and it's always: "soon". I've seen those graphs on how the cost of hydrocarbon fuel is going up, and eventually will go higher than the cost of solar. I'm sure you've seen them too.
Looks great right? You know what they forget? The biggest expense in making solar cells is energy - that exact same hydrocarbon energy who's price increase is being celebrated. When that price goes up the cost of making a solar cell also goes up.
D: Maybe, but that's how it's being sold. And it doesn't help that most renewables are net negative on energy.
E: The research on solar is basically finished. You can't gain any more energy from it that is already being done. The only thing left is reducing the cost. Those super special solar cells that you read about? They use hard to find elements, and we simply don't have enough of those elements on earth to create enough solar cells! Crushing ignorance indeed - you know nothing about me, or how much I know about the field of solar. I know nothing about you either, but you certainly don't sound like you know much about it except for the breathless prognostications from science rags.
Photovoltaic: It's dead. It's pointless, it takes more energy to make them than they produce for a huge time. Solar thermal? Now we are talking, but no one hardly builds them since you need HUGE areas (instead of small incremental installations). You also need an excellent power grid, (but that could be done).
F: No it's not working, it's just costing them money, and increasing CO2 emissions for the rest of the world. Nuclear is it - everything else is just little "feel good" incremental bits. Maybe solar thermal.
