We're almost there, folks! Another several decades and we'll be at 75%, maybe.

Ultimately all energy is renewable.. The cycle might be half a billion years for all of our carbon dioxide, plastics, and other waste to turn back into a fuel source, but it'll happen.

Now go fire up that Coalburner 10,000,000 lifted truck and scream YEEEEEHAWWWW as you barrel down the highway, belching thick black smoke everywhere while the bed spills plastic bottles and grocery bags onto the landscape.

Subsidies make it cheaper, not less productive.  Oil and Coal also get subsides and oil is the most profitable substance ever pulled from the earth.

Can't do 100% bacause renewables can't provide a reliable base load. The wind doesn't always blow and the sun doesn't shine 24 hours a day. Battery storage is a pipe dream.

That's where nuclear should come in. Plus there are already alternative energy storage systems. Pumped water for one, the UK has a large one in a mountain in Wales. Flywheel storage has potential (pun intended). Sand heat storage looks promising for many uses.

Looks like they're excluding nuclear (which makes sense, it's not renewable) but it's also not a fossil fuel.

I have a lot of qualms with nuclear but it's much better than fossil fuels.  We should focus and celebrate any success of something that isn't a fossil fuel.

Sounds to me like it's 24+19 = 43%.  That sounds much better, doesn't it?

/I also wonder what they consider things like wood pellets and methane capture.  Both are probably very small in the grand scheme of things and both essentially rely on waste from other processes (the former is waste wood from lumber companies and the latter is typically capturing it from garbage).  Scaling them up would defeat the purpose.
//Also saw some videos on wave energy capture.  Would be cool if we could scale that up and be economical.  Would only likely work for the coast and the west coast at that (no hurricanes to worry about), but hey, a good number of people live there.  It would be worth it.

There is no technical impediment to sourcing all our power from renewables.  You can do it with the proper deployment of generation, transmission, and storage.  It just comes down to cost, land use, and planning.

That said, US energy policy currently calls for 100% carbon-free power by 2035, not 100% renewable power.  Nuclear is going to play a role.

Pumped hydro storage is much cheaper than battery storage and is seen as the preferred intra-day load-balancing method.  There are a couple of projects in design stage in California that will offset the state's need for gas peaker plants.

That's what nuclear and hydro are for. (Fusion too once they figure it out). Battery storage isn't a pipe dream it's highly practical because we are putting a shiat ton of batteries into service on EVs and vehicle to grid standards are right around the corner which will allow the cars to act as batteries for the grid.

OK. I get that the purpose of the article is to cheer for the team and deliver the good news, so I won't talk to the people who just want to feel good. Go do that.

What bothers me with renewable energy reporting is what gets glossed over. Look closely at the vocabulary. Article says... 25% of generation... well. What is that? How is that calculated? Is it relevant?

Is it the nameplate capacity, which is simply the MAXIMUM that a generator can produce? Because, if so, solar hits that maximum like twice a year for 15 minutes. Wind gets there for a few days a year. Nuclear and coal might never get there, but they get close, and they are steadily useful.

Or is it what is ACTUALLY generated? That is first of all difficult to calculate because people who have rooftop solar generate and use a lot of juice. It never makes it to the grid. And, very sadly, but truly truly, a lot of generated renewable is simply tossed away and never used. It is unexpected and therefore not as useful. It just gets wasted... much much more than baseload coal or nuclear.

And for that matter, what is the denominator? It happened in Japan that the percentage of renewables spiked several years ago, but mainly because everyone cut their consumption by 10 to 20%. And the percentage of nuclear obviously dropped to zero.

I mean, yay and all that, but going by the math and counting that SEEMS to be implied, we are going to need more than 100% renewable to satisfy 100% of our needs or wants. If you don't pay attention to the counting and how people actually use electricity, then that great 25% number will deceive you into thinking that 100% is the goal.

I am an "overbuild and curtail" renewables fan, and my recommendation is that we need to shoot for about 200% generation capability of renewables and/or serious changes to lifestyles.

Wasn't oil/coal only possible because microbes hadn't developed yet to break down the cell walls of plants and phytoplankton?

Seems unlikely those would go away again to let plant matter build up again.

So the goal for the US and California is 100% carbon-free energy and you decide to post a video about California going 100% solar using in-state generation, which omits how nuclear, hydro, wind (on-shore and off-shore), geothermal, tidal, and out-of-state sources could complement solar.

Also, the video doesn't disprove that 100% solar is unachievable, only that it would be very difficult.

Utility scale flow batteries can last up to 30 years.  Pumped storage only needs to deal with evaporation losses once filled, assuming an open-air system.  Lifted and rail gravity batteries need no water at all.

Lets see your proof lithium ion batteries can last 30 years in grid scale applications. In grid scale applications its going to be operated in deep discharge repeatedly. This will severely limit lifespan.  Note: I have designed battery backed solar for remote systems as well as worked for a utility with wind, hydro, solar, and nuclear. Battery backed grid power is a joke.

Agreed. Grid applications are easier- you get predictable cycles and don't have the size limitations a car would, so it's easy to avoid repeated deep discharges. You can design with enough capacity to stay in the "happy place" without ending up with a car too heavy to move, because it's not a car.

That said... one of the lithium-ion batteries I've had that went past ten *is* in a car, and has been deep discharged at high current about twice per day for its entire life. It had more than 80% of original capacity left when I sold it.

Pumped hydro is the only other viable option for storage and there is limited places geologically you can do it no to mention you need an abundance of water.  All others are too inefficient to be considered or can't scale to meet demand.

Oh, okay... so not actually going to have a fact-based discussion, then.


Are you planning to use lead acid?  That won't work well and the environmentalists won't let you do it.

Molten sand? yes you can store heat in it but it doesn't conduct heat well and you can't extract it efficiently.

Compressed gas? Irreversibilties kill efficiency.

Dried leaves?  I don't even know how you'd store energy in those, but they're bad at it.

Poetry?  It's not even really an energy source.  It is reversible, but it's rarely still a poem then.

Lasagna?  It's workable, but it's entirely too expensive for the limited amount of energy you get back.

Feral cats?  High energy density, but serious issues with storage and handling.

Frozen lava?  Turns out this is just rocks, and it takes a lot of energy input to re-melt them, so it's not net-positive.

There are more considerations than just the one you mention. If all you want is the best battery available, then it's likely going to be a silver-zinc battery but that's ignoring the high cost.

Nickel-hydrogen batteries were used in satellites for a long time even though they had a high self-discharge rate because their other attributes made up for that deficiency.

In short, there is almost never a perfect solution.

So now you're just throwing random crap to save face?  Sure, I'll bite.

Vanadium flow batteries have an efficiency rate of 70% to 85%.  Li-ion batteries have an efficiency rate of 85% to 95%.  However, Li-ion batteries require more cooling than vanadium flow batteries, so their effective efficiency rates are similar.  Pumped hydro also had an efficiency rate of 70% to 85%, FYI.  For large utility scale projects, the TCO for VFBs and Li-ion batteries is similar.  And being a more immature product, the cost of flow batteries has much more room to fall over the next decade.

Still waiting for you answer why it is technically impossible to have a grid powered by either 100% renewables or 100% carbon-free sources.
