Using Chrome on Windows I often find notice my computer fans spinning up when I visit javascript heavy sites - Soundcloud and Google Maps are particularly guilty of this, as are those new media-heavy news stories which embed giant videos right through them. I've sat on some websites (with nothing else open) and watched my battery life fall from ~6 hours to ~2 hours.

Most of these websites gain little from requiring so much processing power. I suspect it's mostly developer laziness.

Chrome has made much of their desire for high performance in recent years, but perhaps they should think about resource utilisation as well! They need to throttle greedy websites.
