Chrome, or any modern browser, is not so much directly or itself a problem here.
Flash on the other hand is a problem in itself. If uninstalling system-wide Flash and the one that is embedded within Chrome are not an option, you should at least prohibit it from autoplay.
Misbehaving plugins or extensions might play a role too. Those mentioned by the OP are unfamiliar to me. Starting without them might lead to satisfactory results. They are certainly not needed on every site you visit. It may help to use different browsers or different profiles for one browser. One browser(-profile/account) for work, another one to ordinary surfing.
The main fault that drives this resource hog is on the web itself.
First line of defence against this is to block the grossly overused advertising and user profiling or user tracking that dominates almost every page out there. Any adblocker is of tremendous value here.
To soften the resource usage of a browser it is necessary to
- reduce the number of extensions in the browser
- block ads,
- never to let anything autoplay
Since all these tips not only save your electricity bill and bandwidth everywhere they should also enhance your security and privacy.
So look for these search terms in Google's webstore: adblock, security, privacy and block. (follow the links and use the terms for a personal search in the extensions repository of your browser of choice.)
