My MacBook (with Chrome) does not like this site -- within 5 minutes of opening it and clicking through slides, it got very loud and hot and the battery went down by ~8%.
For a long time I just used Chrome - because why not? It's an awesome browser, especially when you are a web developer. But I was always annoyed about the fan on my MacBook Air mid 2011 spinning all the time - but I didn't connect the dots. At some point though it must have dawned on me and I tried an experiment where I switched 100% to Safari. Now my fan NEVER spins and I get up to two hours more battery life out of my MacBook Air. (yes I know it's a really bad browser on almost all counts - but they do know how to code in an energy efficient way)
