No, no. Greta shreiked “how dare you” at us. That’s it, end of discussion. Greta has weighed in, and some Democrat presidential candidates praised her message and courage.
Nuclear Power was/is/will always be the Energy for the 21st Century.
Solar nets 10 watts per square meter (give or take a fraction).
That’s it.
Ergo 1 square mile for 25 megawatts.
Math accordingly.
Yes, it defies all those variables of logic...so...STOP looking at climate change in those terms.
Atheists and the Godless, are those true believers in climate change...it is their religion and cause, sans any presence of God, much less, Jesus.
So if someone questioned you religion, what would you say?
That’s why.
RE: 1 square mile for 25 megawatts.
I almost always used the handy formula 1 MW = 1,000 homes. So, one square mile of Solar can power 25,000 homes, or for an average of 4 people per home, a small city of 100,000 people.

The Rush To Renewable Energy Defies Science, Economics,by folks with no Common Sense....(More accurate)
Just start collecting unicorn farts as a renewable energey source.
As I’ve said before. Our energy supply needs are like a cake. All wind and solar can ever be of be is the frosting.
You mean batteries?
I think the OP pointed out that battery technology is already pretty far along, and saving more energy in a smaller-sized battery likely won't be achievable. How large of a battery would you need to save energy for several days or weeks?
There is no significant wasteThis is NOT true. Various fusion reactions occur at different temperatures, The easiest to achieve is tritium/deuterium. This releases a neutron which then goes onto activate something. The first likely thing to be activated is whatever the shell material is surrounding the plasma. Lithium would be good insomuch as it produced tritium whe hit with a neutron, but its far to soft and has way too low a melting point to be the material that provides the first wall of the reactor, so while the reaction itself doesn't product radioactive isotopes as residual waste, it produces copious quantities of neutrons that go on to transmute everything in the vicinity into radioactive isotopes. Neutron bombardment also mechanically degrades materials so the life of the fusion reactor itself it not going to be particularly long.
For only 6 hours per day. Multiply by 5 for evernight delivery and storage conversion. And that is with NO margin for clouds. Snow. Rain.
1 square mile of solar => 100,000 people.
Good summary.
Just need to make people aware of how big a square mile of black panels is, and how much that costs to install/maintain.
Next calculation: backup.
You’ll need 240 Watt-hours of storage to evenly buffer the 1m^2 panel’s output (~5 usable hours of power in, 24 hours of power out, average 10 watts per hour).
That’s for just 1 day.
To account for excess cloud cover, you’ll need another 240Wh per day of backup planned. A miserably rainy/snowy week with negligible sunlight means you’ll need 1680 Wh of storage. Sure there may be enough light getting thru to lower that to 1400 Wh.
That’s full cost of a day times 7 days to cover those infrequent times clouds intervene for an extended period, there whether or not it’s used ... and a “brick wall effect” when you run out.
To bracket the upper end of cost, one 1m^2 panel plus 1400Wh storage, courtesy of GoalZero.com, is ~$2000.
Discounts are likely, but then so are other costs (land, maintenance, etc).
For 1 square meter, reliable to 1 week of bad weather.
Now multiply by 2,500,000.
That’s $5,000,000,000.
5 billion dollars to supply solar to 100,000 people ... and if that storm goes more than a week, it’s lights out.
That’s $14/day for 10 years per person.
Hence my earlier “10 watts per day”.
Sun provides 1300 watts per square meter.
When you subtract out night, weather, efficiency, angles, and other factors, your net solar harvest is about 10 watts per square meter.
re: “The Rush To Renewable Energy Defies Science, Economics, And Common Sense”
AND ignores the continued progress of Dr. Randell L. Mills ...
BTW: I’m running my office computer on 100% GoalZero solar (100 watt panel, 250 Wh storage) right now, getting quite familiar with the nuances of positioning, weather, shadows, efficiency, maintenance, cost, etc. It’s not the magic “panel, done” wannabe-environmentalists seem to think it is.
re: “Various fusion reactions occur at different temperatures, The easiest to achieve is tritium/deuterium. This releases a neutron which then goes onto activate something.”
Just have to say it: “old tech.” Look at the progress in harnessing the Hydrino for the future ...
When the next, cost efficient method is discovered/developed the world population will adopt it with no gummint force, because it is cost efficient.
People are smart and make decisions that benefit themselves.
PERIOD.
