Why Do Computers Use So Much Energy?
> <i>Precise estimates vary, but currently about 5 percent of all energy consumption in the U.S. goes just to running computers</i><p>30% goes on transport.<p>> <i>the human brain is a computer. This particular computer uses some 10–20 percent of all the calories that a human consumes</i><p>So society's computer uses 5 percent and our own, evolved over millions of years, uses up to 20.<p>I'm not saying computers can't or shouldn't be made more efficient, but relatively speaking, the title of this article is pretty bizarre. Computers <i>don't</i> use very much energy compared to almost everything else in the world.
