Most new wind and solar projects will be cheaper than coal, report finds:
Almost two-thirds of wind and solar projects built globally last year will be able to generate cheaper electricity than even the world's cheapest new coal plants, according to a report from the International Renewable Energy Agency (Irena).
The agency found that the falling cost of new windfarms and solar panels meant 62% of new renewable energy projects could undercut the cost of up to 800 gigawatts (GW) worth of coal plants, or almost enough to supply the UK's electricity needs 10 times over.
Solar power costs fell by 16% last year, according to the report, while the cost of onshore wind dropped 13% and offshore wind by 9%.
In less than a decade the cost of large-scale solar power has fallen by more than 85% while onshore wind has fallen almost 56% and offshore wind has declined by almost 48%. Francesco La Camera, Irena's director general, said the agency's latest research proved the world was "far beyond the tipping point of coal".
He said: "Today renewables are the cheapest source of power. Renewables present countries tied to coal with an economically attractive phase-out agenda that ensures they meet growing energy demand, while saving costs, adding jobs, boosting growth and meeting climate ambition."

which is awesome, but it's also like saying "a kia optima is cheaper per mile than a truck." coal is for base power, solar and wind is for random power. while solar may be cheaper than coal, it does not replace coal. gas or hydro or nuclear can replace coal - not solar or wind, so the entire comparison is a strawman. the real question is, why aren't they comparing other base load alternatives to coal? oh, because that completely reverses their damn point.
strawmen be strawin'
yeah, coal is bad. yeah, we should pay more money per watt and replace it with nuclear or something else like using solar to pump a lake uphill. getting rid of coal makes energy More expensive, not less. and I'm fully willing to pay that. but when someone simply lies to make their point, their point and everything else they say is now garbage.

Whether you think I lie is an opinion that's up to your autistic brain. You being an autistic social reject incel is the opinion of the world, and the biology of the incurable disease within your defective physical body. I don't lie in any post, but again, you are free to believe what you want. The defective brain disease you have is what provides you with the conspiracy theory that someone who wants attention would go to an unknown forum with under a hundred users. I'm here to laugh at people like you, as that entertains me. Nothing more, nothing less. Enjoy your porn.

Very well said. The real battle is to find cheap grid batteries made from abundant materials. The "gravity battery" seems an ideal solution but it is hard to find enough sites to place a reservoir.

Another option for storing off peak excess energy without using batteries is to just push train cars filled with rocks uphill, same principle as pumping the water uphill but is more flexible in terms of where it can be set up. Sadly I don't have the link to the article I read handy.
Some other non-battery alternatives are flywheels and compressing air into underground salt domes. They all work with varying degrees of efficiency and each could be used in the environment best suited for it. We need to be looking at all of them.

My country (Australia) is the flattest and driest continent, and yet with hydro alone we could have enough hyrdo storage to handle 100% baseload should we want to. We're converting the Snowwy River Scheme into a hydro reservoir for the most populous parts of the country, and we're experimenting with mine pits (that usually need to have groundwater pumped out of them anyway) and our huge southern ocean cliffs for additional saltwater hydro storage.

The grid based batteries approach implies that you're talking about large plants. When you get to large plants, there are already answers. One of them is to use solar-thermal and store the energy in molten salt until you use it to generate electricity.
The house based solar cells, however, don't work well with many of the large-scale storage mechanisms. They could probably be made to work with a pressurized air storage, but I don't know with what efficiency. Most of the other non-"electric battery" approaches, however, don't scale down well. If you've got a water tower, you could use that, but most places find that impractical.

Yeah, discard the externalities and it's cheaper. Include them and it becomes way more expensive.
The price for energy storage goes down fast, the same way the price for solar panels did over the last 20 years.
In 20 years time, they'll be cheap enough for the Average Joe to buffer a week worth of consumption for his household.
Even more, there'll be a technical solution available to Average Joe to be a player in grid balancing - when the demand is high, he can sell some of his buffer to a profit. When Joe Farmer gets the idea, he can mount solar panels above his fences and get a sideline income without sacrificing a lot of his land.

One can hope that the price for energy storage will continue to drop, and it may, but there's no particular reason to believe that it will, at least as far as electric batteries are concerned.
If the graphene-based batteries work out, then it will probably continue to drop. If we remain dependent on Lithium, then that's likely not the case. The cheap sources of Lithium are already being worked out, and new sources will need to be found, or new techniques for extracting it. Of course, new approaches may be developed, but the schedule for "new discoveries" isn't knowable in advance.

I find it silly that we are working so hard on Lithium for non-mobile energy storage.
Weight doesn't mean nearly as much for energy storage that can just sit on the floor all day every day.
I would gladly pay half as much for something that weighs 4 times as much in the realm of whole house storage.

I don't see an "externalities" line item on my electric bill. and this is what we're talking about in the article and discussion. how much the electricity costs, in dollars. just like when we compare car, we compare the car cost, in dollars, and do not include the cost of gas when comparing car prices. if you are not able to comprehend this basic social construct, you may want to get checked out for autism.

Certainly an important point. However, the solutions are already there. One solution currently under build-out is power-to-gas. The round-trip efficiency is around 50% (according to wikipedia). A safe upper bound for the true cost of renewable electricity is therefore 2x nominal cost. As not all electricity needs to be converted, the factor is lower in practice and will come down further in the future. Adding to this further efficiency gains (production and operation) of renewables, it is now time to go full steam renewable, IMO.

Yes. Hydro. Hydro can be augmented with wind and solar. Actually, wind and solar *MULTIPLIES* the power you can from hydro. Hydro is designed currently to provide steady power. But extra turbines can be added and suddenly hydro can do a multiple, depending on outflow limits that do not cause flooding.
Since solar and wind can provide enough power to allow the flow to be reduced allowing the reservoir to recharge, you have a perfect multiplier for intermittent energy source.
So now you see how solar and wind and hydro can provide a lot more baseload than otherwise would be possible with just hydro? If the area can hit 20-40% hydro baseload, you can go past 100% when augmenting with wind and solar.
