Signals electronics (displays, sensors, etc) use so little energy compared to power electronics (the drivetrain system) that it doesn't really matter.
- huuu 11y agoIt does matter. 1 W * 1,000,000 cars is still 1 MW. It's like saying a javascript file of 1MB is ok because there are images of 10MB on the same page.
- ricardobeat 11y agoNo, it's like saying everyone should cut down their JavaScript files by 1kb to reduce emissions.
- mikeash 11y agoIt's more like saying that if you somehow turned off all the fancy electronics, you'd add maybe half a mile to the car's 200+ mile range.
- chillacy 11y agoAn entry level model S has a ~360hp engine, so 0.2 MW A million of those cars is 200,000 MW Amdahl's law: when optimizing performance, target the largest consumer first. And in this case the engine is the largest, by at least 5 orders of magnitude It would save much more electricity educating people to drive less aggressively and use less braking than to remove the sensors
