"Renewable" is in the eye of the beholder. And that’s a big problem.

Check out "Waste of Energy" by Greta Jochem to learn more about the weird world of (technically) renewables: https://grist.org/article/renewable-energy-portfolio-standards-maryland-garbage-incineration/

What about Liquid Fluoride Thorium Reactors leading the New Nuclear Age?

What crap. We don't need any new definitions; we need to not ask stupid, uninformed people and stop allowing the right wing to distort the definition to sabotage efforts or favor their pet source. Renewables are sources that renew or are inexhaustible on any human time scale: solar PV and CSP, wind, hydro, geothermal, tidal, wave, OTEC, biomass. Low carbon does not equal renewable. Clean does not equal renewable.

According to the best scientists and most up-to-date science, we have less than 10 years to eliminate at least 90% of fossil fuel burning or we face unimaginable catastrophe. The survival of civilization in our lifetimes depends on NOT putting more greenhouse gases into the air and taking out all we can, by growing plants and deepening soil. 

We have to avoid burning anything that's not absolutely necessary. Burning trash we shouldn't be producing or that can be composted and used for food crops is insane, even though it's renewable.  

Half of US nukes are already losing money and the rest soon will be; while it makes sense to operate some until they can be replaced by clean safe renewable energy, it makes no sense to build new ones, especially the over-promoted next gen ones that DON'T EXIST. Nukes are too expensive, take too long to build and pay off carbon costs of construction, too dangerous to people and the rest of nature, and to equality and democracy, use too much and heat too much water, have intractable waste problems. They are not renewable. And the market religion that so many pro-nuke people swear by otherwise, has decreed they're not viable.

We have to implement an immediate massive climate mobilization dwarfing the US' in WWII. Read more: www.theclimatemobilization.org

Nicely done. The last bit had 'fossil fuels and nuclear' (83%) and 'renewables' (17%). Given that the critical issue is emissions, that's a dangerous way to think about things: It needs to be 'fossil fuels' vs. 'renewables and nuclear'.

Nuclear is very low-carbon, and has very low ecological impact in comparison to most sources. We have got to get beyond the 'ohh but its scary' thing, at least for the time being. Nuclear is definitely on the 'good' side of any sensible equation. I like to use the terms 'clean energy' or 'low-carbon energy', then obviously laugh at anyone who tries to put 'clean coal' in the 'clean energy' bucket - that's just stupid (unless by clean they mean 100% CCS in which case I guess that's acceptable).

Music feels a bit too loud. It's pretty distracting.

Low-carbon = renewables + nuclear is optimal.

Renewable : climate change :: horsepower : speed
