The grid may not directly care about efficiency of individual components but to the system as a whole makes a huge difference. A 5kW dryer that's only 80% efficient will actually consume 6.25kW of power (imagine if that was the case for 1000 house holds that would be equivalent to 6.25MW of power, thats something that cant be ignored) the fact that things are more efficient helps a fuckton.

Also I never argued that the grid cannot handle EVs charging at night I'm not even sure how you came to that conclusion, once again the grid cannot withstand the worst case scenario of most consumers charging EVs during peak hours. Once Again if you read my original comment I was referring to the infrastructure upgrades to the substations that feed power to neighborhoods/homes to meet the increased demand. Also as far as need to be able to supply all that power I never said it was actually necessary to do that but the system but rather the grid needs to be either powerful enough to meet the peak demand or have safeguards in place to prevent critical faults/failures that would cause interruption of service to customers.

As far as the "Typo" goes its not just that you put kWh where it should of been kW. You incorrectly stated that your car charged 30kW in 5 hours that sentence does not make sense. I even explained the difference between kWh and kW (you can charge at a rate of 30kW for a period of 5hrs, giving you a total charge of 5 x 30 x 3600 doing this will give you the energy stored in your batteries in kWh (kWh is how batteries are measured or AmpHrs if know the voltage and divide by it).

As far as my hypothetical FUD goes: its not really a hypothesis if its happened. Electric grids have failed before, we have had natural disasters which have caused people to panic, and there's been too many examples of failures of infrastructures that have caused plenty of harm and property damage (I'm only here fighting to prevent it yet its FUD...). Once again if the information that I present to you gives you FUD that's a you problem, where I come from its simply reality.

I also like to point out you have tried multiple times to deflect from arguments by using words like FUD, whataboutism, and twisted my words to the point of calling people stupid. If you truly believe that these scenarios are as improbable as you believe them to be please articulate as to why you believe that to be the case. Saying we have this one fits all solution of just charge vehicles at night is complete BS. you yourself admitted there maybe a situation where youd charge during peak hours I wonder how many people will have the same thought during the same emergency? My point always was that you must have a plan to account for the worst case because thats when shit hits the fan not during "ideal scenarios".
