Are you trying to argue that despite the two words share a root, that lithium isn't common in the lithosphere?There's ...
wonder what the grid will look likeElon Musk & the engineers at Tesla estimate that all new cars/trucks sold in 2030 could be full electric. By 2050 the entire population of cars/trucks would be full electric.
Using technology existing today, if started now by 2040, it is theoretically & economically feasible to power the entire U.S. using only renewables (hydro, geo, wind, solar).
Hopefully the rate of roof-top solar adoption increases, as well as wind and grid scale solar, it should be fine...wonder what the grid will look like
It is certainly going to be interesting to watch the evolution but don't expect things to happen to fast. Here's the situation with home rooftop solar:Hopefully the rate of roof-top solar adoption increases, as well as wind and grid scale solar, it should be fine...
That's the trend in new neighborhoods but there are limitations on high voltage distribution above the 15 kV class.But I really wish we would start a program on putting all utilities in the ground, were power would not be knocked out by wind or a drunk driver (last time I lost power was because a car crashed into a pole and severed it).
yepAs Elon says, and I think he knows better than thee; Lithium is very abundant, look at its position on the periodic table. So, stop your fear mongering. All will be good as soon as Elon finishes building his own chip factory. He is already building batteries. He manufactures his type of stainless steel he uses. I'm guessing he's looking into mining whatever resources he needs. Elon doesn't baulk at difficulty - he assesses and decides on the most efficient way to conquer. Get used to this from Elon. peace
I am still not sure why power lines have to go in the air. We manage to put other utilities in the ground (water, gas, sewage) and other countries have found a way to do it... (and I am aware of how grounding works)It is certainly going to be interesting to watch the evolution but don't expect things to happen to fast. Here's the situation with home rooftop solar:
It is doable. It is just 10 - 15 times more expensive, much more difficult to maintain and repair, has half the service life of an overhead system, requires active cooling... Looking to the future elimination of these lines by going to the more localized mini-grids seems more appealing.I am still not sure why power lines have to go in the air.

It's just not practical to build an aluminum smelting plant that only works a few hours a day or that must be shut down if the wind calms.Yes, storage will be important, but so will be adjusting power hungry industries and processes to when there is the most abundant energy.
I fantasize about huge solar farms with hydrogen production plants co-located. There would also be fuel cells or turbine generators there. Hydrogen would be produced when the sun shines at terrible efficiency but no one would care about that because the electricity is so cheap.Some others have talked about making hydrogen for use as a fuel (for industrial furnaces, rockets, fuel cells).
We are just agreeing that the missing piece right now is storage. I've got to mention one of my favorites here that works when the main load is A/C and that's ice (in the conventional sense - not the abbreviation we use here so much). Use PV energy to freeze lots and lots of water in a reservoir and melt the ice to air condition a building. There was a company in Ca that did a library and school or two that way IIRC but I think they went TU.There is also the traditional pumped hydro (as you mentioned) or the new stacked/uphill weights. And of course, ....
This works as long as the rooftop solar production is very limited. In VA the utility had the state regulatory board limit total solar production to 1% of the load. That's been increased somewhat but without more storage management of this source of energy is going to be difficult.And, even with most residential roof top solar is over production because traditionally people were at work during peak production, it still takes some load off the grid, freeing up capacity for business/industrial/residences without solar (or lowering the baseload generation needs, as you point out).
Literally that's how aluminum plants work. They operate different shifts depending upon power availability. Solar is very predictable, but traditionally they use seasonal hydro.It's just not practical to build an aluminum smelting plant that only works a few hours a day or that must be shut down if the wind calms.
