Agrivoltaics, saving farms

You won't admit that switching from fossil fuels to solar will result in a net cooling?

Burning less, or no, fossil fuels will cool the planet.

What about replacing fossil fuels with solar power?

I find it hard to believe that they get much yield from plants constantly in shadow. Last I knew plants needed sunlight for photosynthesis. But then again I still believe men are men and women are women

The photo in the OP's article shows cattle being sheltered by a solar array. Basically a barn with solar panels on the roof. There is not enough cattle on a ranch to sell solar energy. It might be fine for the ranch's personal use but it ain't gonna provide enough sell.

Not viable, power is only produced half the day and 'fossil' fuels provide more KWs.

I understand. I'm not suggesting that we should. I'm arguing that we shouldn't. The planet (i.e. life) needs more atmospheric CO2, not less.

OK, I misunderstood.

Burning fossil fuels allows 100% of the released energy to warm the planet.
Adding solar panels allows about 90% of the solar radiation hitting the panel to warm the planet, instead of 70%.

Replacing fossil fuels with solar does not affect waste heat from electricity usage.

Converting to solar reduces almost all waste heat from generating electricity.

And then there's the 15 to 20% of photons being converted into electricity which directly impacts the earth's energy budget and creates localized cooling at the solar farms.

Then there's the reduction in CO2 emissions.

All of which means that converting from fossil fuels to solar power will result in a net cooling compared to fossil fuels.

Do enough (0.7 w/m^2) solar and the planet will switch from net warming to net cooling.

And localized heating where the electricity is used. So, that's a wash, you know, conservation of energy.

Your original claim, "any solar radiation that is converted into electricity is solar radiation that does not warm the surface of the planet", is wrong.

Because it does warm the planet. And so does the extra 20% of the solar radiation that's absorbed by the panels.

My claim is that the widespread use of solar is a horrible idea in the middle of an ice age.

If that were the case there wouldn't be a localized cooling affect at the 116 solar farms that were studied

Right.

Because, magically, solar radiation that is converted into electricity, doesn't heat the planet.

It isn't the case that 0.10 albedo panels reflect less solar radiation into space than 0.30 albedo surfaces?

 

[ding]

Right.

Because photons that are converted into electricity are photons which don't heat the surface of the planet.

And because...

They heat the location where the electricity is used.

How do you explain the localized cooling at 6 solar farms?

How do you explain the violation of conservation of energy your claim requires?
