You talk about intelligence but then act like a zealot. Don't get me wrong, I have solar panels myself in Spain, but is not Utopia.

Solar panels use a lot of space that could be used for other things like growing food. They make the earth extremely hot as they absorb so much heat from the sun. The political zealots talk about climate change but avoid to talk about that.

It is not excuses, there is very intelligent people working on those problems. Natural gas makes a lot of sense combined with solar and wind because solar only works when the sun is above and wind when the wind blows. You need something for winter and nights. Energy storage is very expensive, and also require lots of energy and raw materials for manufacturing.

For wind mills to make sense you need wind. Lots of countries do not have wind, and also produce heat an noise and kill birds.

In Spain, when the price of the panels and inverters go down, if you have users nearby, it makes sense. In Germany, with half the insolation, it does not.

There is no "free" anything. Everything has its ups and downs.

We need less politicians, lawyers without knowledge of science and engineering.



Of course there's an impact, but the question is "what is impacting us more?"

> They make the earth extremely hot as they absorb so much heat from the sun

What are you smoking? The sun is not sending more light to the places with solar panels. It just absorbs light that is already hitting earth. If anything it makes earth cooler as it absorbs light that would otherwise just hit the ground and make ground hotter.


If the solar panel reflects less sunlight than what would otherwise be there (which seems likely to me) then grandparent is (technically) correct. The energy the panel absorbs eventually turns into heat (although before it becomes heat, it might in the form of electricity be transmitted far away) just like the sunlight energy that a rock absorbs also turns into heat.

The correct response to grandparent is that the magnitude of the increase in heat is small enough to be safely ignored.


It is more like

A. light absorbed by solar panels that eventually turn into heat

B. light absorbed by the ground which pretty much all becomes heat

I'm pretty sure B is much greater than A.


Essentially all of it turns into heat except the part that is (immediately) reflected back into space -- and solar panels are darker than most of the (non-grassy or only sparsely grassy, and the grass is golden, not dark green or on the roof of a building) sites where solar panels are typically sited, which means they reflect less back into space. Ergo, erecting a solar panel adds heat (but again it is negligible compared to the reduction in co2 emissions).


At least in the US, the arguments against solar and wind are usually not out of concern for land area needed for food growth. The opponents tend to use unsubstantiated FUD.
