Didn’t congress pass a gargantuan bill a few years back for this?

Yes but that money went to the working groups who need it more than silly bridges.

The BIL alone has already funded ~30,000 Road/Bridge projects totaling $95 billion so far, plus hundreds of billions more on other infrastructure. Would you mind pointing to the specific working group funding that you have an issue with and which specific bridges need repairs but had their funding rejected?

These are bandaids. Fine in themselves, but not addressing the real problem. The US really need to legalize transmission line construction!

Lines? Why? Why aren’t we taking better advantage of wireless power transmission? Seriously, Tesla planned to construct Wardenclyffe Tower back in 1901!

It looks like during last year's heat wave, California FINALLY broke its previous all-time peak load of 50,270mW in 24 July 2006, with a whopping 52,061mW on 6 September 2023. Still, peak usage year over year looks flat to my eyes. I'm sure we can't keep time-shifting and efficiency engineering ourselves out of a fundamental need for more total energy for a huge % of EVs and the push to phase out natural gas, but it…

It's pretty clear from the context what units you intended to use and I kind of hate to be 'that guy', but just FYI: mW -> milliwatt, MW -> megawatt.

Yeah; it's a good start. As per the third paragraph of the article: "In New York, Algonquin Power won a $42.9 million grant to install devices that automatically redeploy power when lines are overloaded. Virginia’s Dominion Energy won $33.7 million for a project that includes devices that will let it adjust power distribution in response to changing conditions on the grid. The funds are part of a $3.5 billion program…

When you adjust for inflation, the price tag of the 2021 infrastructure bill is twice the construction cost of the entire Interstate Highway System. Are we getting two entire Interstate Highway Systems worth of infrastructure for our money? If not, I think that's the first problem that needs to be solved.

Not just power grid … US infrastructure overall is in need of a “jolt” (updating). Bridges, highways, power grid and more are all aging and in need of massive updating / refresh.

I have 0 faith in our governments to carry out any long-term projects that aren't military-related. Like wasn't a trillion dollar infrastructure bill passed a couple years ago? Where has all that money gone?

My town is busy replacing lead service lines, fixing up water mains and building a new treatment system at the water plant. Users are paying a significant share of it, but there's federal infrastructure funding also.

The aging power grid is not capable of charging millions of EVs on instant high current demand.

Until that happens, EVs will never be useful enough to make ICE cars obsolete.

"It's the infrastructure, stupid".

The US and other countries should have spent those trillions on infrastructure instead of wasting lives and treasure on stupid military adventures. Too late now, the countries are going down the gurgler big time.

It's not that much power compared to the terawatt or so of peak capacity, and the "instant" nature of a single car doesn't affect the overall grid in the slightest.

For some rough math, people drive 10 billion miles per day in the US, and at 3-4 miles per kWh that's an average of 105-140 gigawatts. Average production is half a terawatt, so replacing half the cars on the road might only need 10% more average power production, and almost all of that charging can be done off-peak without an impact on transmission.

In the optimistic case, electric cars can even reduce peak loads on big distribution lines.

California has lots of problems, but availability of money is not one of them. I have no worries whatsoever about our ability to properly handle changes in demand going forward. Will a bunch of money get wasted and mis-managed? Of course. It wouldn't be CA if we didn't do that! But we'll still grow just fine.

52 W is not a particularly high peak load.
