I'm all for V2G and V2H schemes as these actually help to levelize grid demand. Solar by itself does the opposite. Only solar by itself is cost-competitive, and only so long as it doesn't exceed a certain low percentage of electrical generation. How do I know? Because that's exactly what utilities are doing. If solar was cheaper, they would invite me to pay a lower bill for opting in for solar generation. They do the opposite.

There is a likely a place in the future for solar to be competitive with other generation sources, but in certain locations only. Saying solar is the solution is like saying geothermal is the solution. True, that's the solution if you happen to live in Iceland or can get a permit to tap into Old Faithful. Every geographically unique area lends itself to differing electricity generation portfolios.

You keep saying that, but you'll be relieved to know everything is functioning normally downstairs. ;)
That's why utilities are getting bids for Solar+Storage nowadays. Solar-only is old news.

Solar plus batteries is now cheaper than fossil power | Science


BTW, it's a Matrix reference. LOL

Here's a test you can do to tell if a location can be used for geothermal energy. Grab a fistful of dirt from the ground and taste it. If it tastes like dirt, you can use the location for geothermal energy. But some areas do have higher temperature increases per depth, making it cheaper/easier. Most of Nevada is about as good as Iceland.
I've read that concentrated solar power has about the lowest levelized cost of renewable power (excluding hydro and geothermal). It's able to store heat to operate through the night. With a huge thermal mass, it's able to average out the ups and downs of solar production.

Subscription paper - no access.

Solar + batteries isn't cheaper than hardly anything. Batteries are supply constrained, which I mentioned above. That means even if you could get a few hundred houses retrofitted with batteries, there isn't supply for millions. Prices would skyrocket for that kind of demand.

BTW, it's a Viagra reference. :LOL:

Like the Ivanpah one? The one that uses natural gas for an hour to start up every day and is widely considered an environmental failure? And Tonopah, which completely failed and taxpayers footed the bill? I'll pass.

Supply/demand will ensure we roll out solar+battery at a rate that the market can sustain. Flow battery was talked about and makes lots of sense for industrial and home battery uses but it needs to get cheaper before utilities will start adopting it.

Yeah, not a fan of that either. It uses the heat to boil water and turn the turbine... don't like water reliant processes in the desert.

The next generation of EVs will include much bigger vehicles some of which will routinely tow trailers - boats, horses, campers, utility trailers, etc.
The percentage of people who are going to be towing boats, horses, campers and utility trailers is a small fraction of the total driving population, and even those that do are unlikely to be towing them every day.

If there's one thing I've learned by forgoing the cost to upgrade the underground service to my garage and be content with charging my Bolt on the OEM EVSE, it's this: for home charging you don't need to size for the worst-case daily requirement, you only need to size for the average daily requirement.

On the rare occasions you need more you can use the public fast charging infrastructure to add a bit of charge before plugging into your own outlet overnight. So far in 3 years I've only needed to do that once.

This.

Yes, I installed a 30a EVSE at home (which I bought used). I even had to trench it out to the driveway. I did the work myself and the 120’ of 8/2 wire was free. I’m in about $450-$500 for the whole setup. BUT… I can charge at work with my stock 12a cord plugged into a 240v outlet and leave with a full battery almost every day. The only time I charge at home is on Monday and Tuesday (which is my “weekend”).

My daily commute is about average — 30-40 miles. I could handle that with 120v charging if I wanted to. Like I said, I did put in a 30a setup at home, but mostly just because I could… and because I would like to avoid public charging.

I can imagine a lot more controlled charging. Just like you can tell your Bolt that you leave for work at 8am, and it will hold off charging until it is finished just before you need to leave, you could have a system that starts charging earlier but at an appropriately throttled amperage. So, instead of having to charge for 3 hours at 40a, it could spread it out to 10 hours at 12a. That would be easier on the grid, your household wiring, and your EV’s battery.
