Quote: “Everything a Tesla product runs on comes from a SECONDARY ENERGY SOURCE…ELECTRICITY… […] which means that effectively there is an efficiency loss when the electricity is produced, transferred and stored, etc. […] And those losses are truly significant spite what the clean energy folks would have you believe”

It’s also been claimed (source: https://insideevs.com/efficiency-compared-battery-electric-73-hydrogen-22-ice-13/) that fuel production efficiency from well to tank for petrol cars is 44%, which would work out to a staggering 56% loss.

In contrast, your cited 7% loss in electricity transmission, implies 93% efficiency in transmission. There’s room for a LOT more than 7% losses without coming near the inefficiency of producing and distributing petrol. I mean, think about it — you even have to burn petrol just to truck the petrol to petrol stations.

It is disingenuous to cite an inefficiency number for fueling electric vehicles as if it is some new and worrying obstacle unique only to electric vehicles, one that isn’t shared by petrol and diesel vehicles. Is there someone out there who only drives disposable vehicles that get thrown away when the tank is empty? I mean, beside literal (non-SpaceX) rockets?

This is purely on the charging/petrol station side, of course. It’s also widely accepted and common knowledge that internal combustion engines are staggeringly inefficient users of fuel. They lose massive amounts of their energy to unavoidable heat loss.

No one is contesting this. In fact, ICE makers compete with each other to come out with efficiency gains. For example, a 2014 article about a new Toyota internal combustion engine lauded it for reaching an impressive 38% energy efficiency (as in, only 62% of energy is wasted by the engine). It referenced this against most petrol engines, which reach a mere 20% efficiency. Diesels are a little better, typically approaching 40% efficiency.

That’s 60–80% of a tank of petrol going into thin air as efficiency loss (at least on a day when you don’t need to heat your cabin with a fraction of the excess heat).

TL;DR: The clean energy folks aren’t losing sleep over a 7%+ efficiency loss in transmission to fuel electric cars.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
