If "we" had started in earnest in say 2000, "we" might have been able to make a consequential difference.

With nuclear off the table, all I see is promises with no substance.

China's greenhouse gas emissions exceed U.S., developed world: Report (cnbc.com)
China's greenhouse gas emissions exceed U.S., developed world: Report (cnbc.com)

China’s greenhouse gas emissions in 2019 exceeded those of the U.S. and the developed world combined, according to a report published Thursday by research and consulting firm Rhodium Group.
China’s emissions more than tripled during the past three decades, the report added.

China is now responsible for more than 27% of total global emissions. The U.S., which is the world’s second highest emitter, accounts for 11% of the global total. India is responsible for 6.6% of global emissions, edging out the 27 nations in the E.U., which account for 6.4%, the report said.

I just went by the Davis-Besse Nuclear Plant yesterday it's right off of rte 2.Very clean and didn't seem revolting or dirty

Owned by FirstEnergy Nuclear Operating Company, Davis-Besse is a pressurized-water nuclear reactor that produces 908 megawatts of electricity, enough to power 450,000 homes without producing greenhouse gasses.

That may be, but it's not an option in the US, nor in Germany and Japan.  We're closing our units faster than they are coming on line for the next decade.

A landmark United Nations report has declared that drastically cutting emissions of methane, a key component of natural gas, is necessary to avoid the worst impacts of global climate change.
The world could slash human-caused methane emissions by up to 45% this decade, according to the Global Methane Assessment.
The report represents a shift in the worldwide conversation on how to best address the climate crisis, which has focused on setting longer-term carbon dioxide reduction targets.

I think we could practicably do a better job with methane release.

The Saturn Moon Titan has liquid methane lakes, and it's pretty chilly.

Methane is interesting, it's CH4 of course, "swamp gas", generated naturally by anaerobic "fermentation" of organic biomass.  Old land fills usually have a methane recovery system of pipes in them, many do anyway.  Then they flare it off, it has low fuel value because there is a lot of CO2 in it as well.

I had a composter in Cincy in the back yard where I disposed of a lot of food and yard waste.  I had to turn it pretty often to keep it from matting and going anaerobic and smelly.  The funny thing is when the waste was digested, there was almost nothing left, you didn't get handfuls of nice compost, maybe A handful, maybe.

We have a bin downstairs here for compostable waste that someone collects.

Nuclear should have been the bridge to gap coal and solar/wind, but we ditched it for 30 years and are running away from it now that it didn't just pick right up where it left off.
Duh, an entire generation of workers aren't nuclear plant-ready because it wasn't a potential job as they grew up.

My son's in-laws have a seasonal camp site just about a mile from there. Nice campgrounds right on the lake. Very clean and orderly and with all of the trees, you don't even notice the nuclear plant.

Nuclear power is "not the same kind" as wind and solar, one is steady, the others are intermittent.

Nuclear is also space intensive, it takes up little space per kwhr.

We should reprocess our spent fuel, like France does.

"We" don't like solutions, only problems.

As I understand, nuclear is also quite expensive. I think many of the reasons for this are artificial [much regulatory], from what I've read. But some are related to the access to fuel, which isn't just falling from the sky [or else we'd all have died of radiation poisoning].

But I think that's a lot of the reason that we walked away from it for 30 years... It was economic.

'Course, a permissive regulatory environment and a carbon tax would make it a hell of a lot more economic... But nobody listened to me before... Why would they start now?

Nuclear is very expensive.  IF we could build standardized reactors instead of one offs, it would help enormously.
