In theory, it's three different [ranked] views of the same propaganda.

The counter to the Green New Deal is becoming reorienting American industry away from (our new common enemy) China. According to Scott Adams this morning.

If it includes Thorium molten salt reactors, liquid metal batteries, jet fuel from plastic confetti and protein from air and water, and of course biochar it just. might. work.

Here is some complete data from an intentional community owned solar array in Ithaca, NY 14850. This 50 kW array is privately owned and gets the best care and cleaning and shows us the actual opportunities and constraints of solar PV in snowy locations.
.
https://ecovillageithaca.org/live/living-greener/
.
The performance in Canada or Russia and Eastern European regions will be worse.
.

.
Here we see the all time electrical production of the 50kW community owned solar PV system at Ecovillage Ithaca, NY 14850. These panels are privately owned by an intentional co-op and receive the best care and cleaning. Taking the five good years value of 60,000 kWh, shows us that it is normal to expect a capacity factor of 13.7% at best for solar in upstate NY.
.

.
Electric heat and solar pv in Winter do not fit
.

.

.
There are many days near zero output in the Winter and the average for the month is only 5.5% of nameplate capacity.
.

.
15 days out of 18 with literally NO power. Again, there are many days near zero output in the Winter.
.

.

.

.

.

.
The best month ever produced 22.2% of the nameplate capacity.

See in new Mexico I should be able to hit 25% for the year on a fixed array.
During the summer on tracker arrays you can hit crazy numbers like 40% in the summer. But it's cheaper just to buy 2 or 3 times as many panels and stick them in the ground.

Manual tilt ground mounts at 66* would help with the snow but I have never seen anything other than fixed. And usually at 33* or less (43* N latitude). They are not even trying to get anything out of the panels in the winter.

No solar energy in the tough winters... Solutions???
Nuclear power just for the winter (when home heating it's more required)???

Solar concentrators to help solar panels get better output efficiency?
But with clouds the light of the sun became no longer parallel, but difused, So a concentrator to try work with difused light can be a challenge.

If they could develop a way to harvest enery the the difference of potential (thermal) from cold air in relation to the warmer temperature of ground 3 meters away from surface.

It's easy to move a turbine with heat, as you just need to create vapor. But with cold...

I mentioned migration on another forum the other day and look what Ugo Bardi writes today:
.
"But this trudge along the New Trail of Tears is lined with a gauntlet of perils: the area of the globe shrinks with increasing latitude, and the available area of mountains shrinks with increasing elevation. Competition for livable space will be fierce, and the refugia to which many species will be confined as their range shrinks will become extinction traps for some. Barriers to movement, both inadvertent and intentional, can be death sentences to those migrating. Roads and other human structures have dissected the landscape, either preventing motion or making it treacherous. Rivers and seas impede human migration, and border walls seek to prevent it altogether. But the migrations will continue and even increase against all odds; when life in one location is not viable, there is no other option."

??? The seas are how humanity spread around globe in prehistory, and the rivers are all supplemented with canals. Walls do work though.

If you put an underground skirt of insulation around the base of the structure it encourages the thermoclines to sorta bubble up under the floor.

"Of course there are alternative forms of energy that are becoming more efficient and affordable every year, and that’s a good thing. But ironically the alternative energy sector as it now exists relies entirely on fossil fuels. We need to recognize that fossil fuels are essential in the whole supply chain of a windmill or a solar panel, in mining the raw materials, shipping them, manufacturing them, transporting the manufactured products, even the advertising and government subsidies – will this process still be affordable when the Industrial Revolution reaches the bottom of the barrel? The last two hundred years are not representative of the life of our species. They were built on a foundation that is not sustainable, and when it crumbles, our capacity for innovation may need to be replaced by our capacity for renovation. Old technologies that were designed with the limits of economics and planetary sustainability in mind will once again become valuable, and our lives will have to change drastically as a result, All of the sane reforms I and others write about will become, maybe not inevitable, but certainly desirable options once we view the world and ourselves without the distortion of the fossil-fuel lottery pay-out. Some day soon we will have to go back to living on our yearly income. We will still be inventive when that day comes, but our inventions may look more like clever PTO shafts on horse-drawn farm equipment and less like space travel."

Thank you for your confidence in me, instead of FOX, who has mesmerized re-pubic-lick-uns. "put-it-in" has floated "don''T rump" since his bankruptcy. Once the House gets "don'T rump" tax papers, much of the "don'T rump"/"put-it-in" connection will be clarified. We already know the russian oligarchs(blessed by put-it-in) have had their ill-gotten gains, money-laundered by "don'T rump". One property transaction alone, cleaned up 100 to 200 hundred million dirty dollars, & '"don'T rump" got fatter.
