Things like transmission system losses (for electricity) and ICE efficiency (for vehicles, only about 20% of the energy in fuels is converted to useful things like motion).
More or less rejected means "lost as heat before we can do something useful with it".
- revelation 10y agoSure, but where do we stop? At the customers electricity socket? Behind all power supplies, but before the specific device? Computers will turn essentially all power entering them into heat. But then by that measure we can never make an efficient computer but would have to look at something like flops/W to give us actionable information. What is a measure we can apply consistently to computers and cars and get actionable information?
