Seems to be sloppy research. Doesn't seem to understand the difference between world/US and US grid doesn't have to supply the worlds' EVs.
>> There were 16.5 million electric vehicles on the world’s roads in 2020
That's the world, not the US. The US has less than a million EVs, maybe 2 at most.[1][2]
>> this is expected to rise to 300 million by 2030. But with these rising numbers, the US grid could struggle without investment and changes in charging habits, a Stanford study finds.
Projections are 26 million[3] by 2030 in US, 300 million is worldwide, but what has US grid got to do with it?
But, even if it were true, it won't be as big as a challenge as its made out to be.
a) There is plenty of free renewable power. Renewables oversupply, which is currently being curtailed. Renewables are growing, this will mean plenty of oversupply coming online. If only there was a way to create demand.
b) Wholesale prices went negative about 200 million times across the seven US grids in 2021
c) EVs can absorb all of this free energy or get paid to absorb
d) Right now, energy bill is split between gas, electricity and nat gas. Households switching to EVs will have solar, bringing their bills to zero as well as no new demand on the grid.
e) Quite possibly, there is no net new demand. A comment on HN: It takes about as much electricity (or energy) to refine a tank of gas as to charge an EV. [5]
