I never said they did. I did say that overall during the summer months they use more power than my EV's (40 to 48 kWh vs 10 to 20 kWh) and they run during peak hours when more strain is on the grid. My EV charging barely registers on my power usage graph. If I didn't have solar, you would see my daytime energy usage (4PM to 7PM) spiking way up...and we don't even charge our EV's until after 9PM

Hard to choose really which is better.

Hmmmm. I like the top picture . Nothing like the smell of crude in the morning! Those solar panels probably burn insects and birds to death. And look at all the shade they are creating.....

My personal opinion and I am being clear that I do not speak for my industry or employer is that multiple sources of electricity production are going to be necessary. Solar is going to work for some people who do home charging. I plead absolute ignorance on how effective solar is during Winter months and in some areas.

My perspective is solar works in some cases, wind maybe works in some cases, hydro maybe works in some cases, and the gasp of burning fossil fuels is necessary now. Hopefully, people realize I am not against EV adoption and am very much in favor of it. California cannot support the existing demand and that’s been the case with rolling blackouts during Summer months for more than a decade. I don’t see power generation as from just one source. We need multiple sources.

The way solar works, if your panels were spec'd out right, you generate most of your electricity May through September, and the surplus electricity becomes either a credit or the provider buys it from you and cuts you a check. In my instance, I generate about 150 Percent of my energy, so my electricity bill is in the negative at the end of what they call "True Up". I pay a flat $137 a month for the panels

Grid in the U.S. is already diversified. Coal, natural gas, hydro, nuclear, wind and solar. Problem is most is gas and coal.

In Canada we don't need to do much of anything. Replace natural gas with some solar and done.

Fine, but the electric grids aren't just depending on what you or I (typically) use. If they did, there would be no problem. I, for instance, don't use a lot of heat in the winter or a lot of A/C in the summer. I have figured out ways to keep my small town house tolerable without much assistance or electrical use. My monthly electric bill (without solar use....just regular hook-up) typically varies from around $20 to $60.....a little more if it is very cold outside. (I do not have an EV).

I'm wondering why you are precisely homing in on EV's. The reason I posted the graph from my bill is because I'm showing you that my 4 EV's have the least impact on my overall usage. Sure, they did raise the amount of electricity from pre EV ownership, but overall their impact has been very low. On the flip side, I've used way less gasoline...probably hundreds of gallons less over the last three years

I'd like to know as well.

Norway is currently 25% EV somehow they are not having grid failures left and right.

maybe its 30 in canada where there's a lot of gas heating and much less a/c use. here in florida, it's almost all electricity (no gas heat anywhere).

i checked my home energy and it's from 36 to 83 kwh per day (based on dividing these monthly numbers by 30 from the last year)



and i have a VERY energy efficient home with brand new very efficient a/c systems, under roof foam insulation, etc. i do have a pool but i switched to a variable speed pump a few years ago which made a huge difference.

i have about 3100sq. ft and have THREE a/c units - one big for main part of the house (runs more during day), one small for master area (runs more during night) and one other small one for upstairs bonus room which is left at high temp most of the time as little time is spent in it. the 3 units make things more efficient.

like canada, norway has vast hydro electric power capacity. i'm also not a person who believe the u.s. grid is in jeopardy because of ev's.

It's not a critical issue yet, but, a number of years down the road, when there are many millions more EVs on the road than now, that's when we could see problems if the system is not upgraded.

I had no idea there was that much energy harvested from hydro as posted above.

Totally blown away, didn't see that coming.

Hi Bit!

I drove by it once but didn't get to see much.

That hydro electric dam has been there forever and I have no idea how much it contributes to the electric needs.

One thing I do know is millions of people near there and it gets so friggin' cold!

So, I'm guessing that dam is tapped out but I really don't know, just a wild guess and probably way off. Lol
