A common criticism of EVs (electric vehicles) points to the demand widespread EV adoption will have on the electrical grid – that is, say, by 2036, as many expect, battery electric and hybrid powertrains power 71.1% of all light vehicles built, then the grid will blow up. Or something like that. The grid won’t be able to cope with soaring EV demand, in other words.
This analysis suggests otherwise using some very detailed and thorough inputs.
Bottom line: If every vehicle in the US became an electric vehicle overnight, the grid would see a 32% increase in energy demand. Of course, the entire light vehicle fleet will NOT become electric overnight, so 32% represents a worse (or best) case scenario.
But the EV transition will not happen overnight. More likely, by 2036 battery electric vehicles will have a market share of, say, about 35%. The latter suggests a much more modest increased load on the grid of about 11%.
Yes, many electrical grids in developed countries, from Canada to France, suffer from aging grids that need upgrades. But it seems reasonable to assume that in 15 years, electricity suppliers should be able to handle an upgrade to meet an 11% increases in demand from EVs.
And that’s not taking into account the fact that many owners will charge their EVs overnight, when energy demand is low and pricing is more affordable.
Naturally, there are those who disagree. To them I ask: show me your numbers, please.
The electrification of the automotive industry represents one of the most dramatic shifts in energy consumption behavior in human history....Read More...
