Adobe's CTO tells Fast Company that Flash draining batteries is a "False argument to make"...
Yesterday, Fast Company interviewed Adobe CTO, Kevin Lynch, about earlier reports which revealed that a Macbook Air without Flash installed could save hours of battery life.
It seems as though after Steve Jobs denounced Flash, Adobe has been working hard to salvage and defend their name. With the introduction of Flash on Android phones and Flash-to-HTML5 conversion tools, Adobe has been doing pretty well for itself. Despite their successes, Adobe has come under heavy criticism over the past week which has finally prompted a response.
Lynch claims, "It's a false argument to make, of the power usage. When you're displaying content, any technology will use more power to display, versus not displaying content. If you used HTML5, for example, to display advertisements, that would use as much or more processing power than what Flash uses."
Although Lynch has a point here, it looks like his solution to the battery problem would be turning your display off. He continued to state that several studies have confirmed Flash's higher battery life and argued that HTML5 was much less reliable. Unfortunately for all of the battery concerned flash users, Lynch didn't discuss any sort of solution to the problem shown with the Macbook Air.
Regardless of all the criticism and the success of HTML5, Lynch was optimistic about Adobe's future. In response to a question about HTML5's success being good or bad news, Lynch stated, "No, that's good news for Adobe, We support HTML. We're making tools for HTML5. It's a great opportunity for us. Flash and HTML have co-existed, and they're going to continue to to co-exist."

Solution: Don't buy a Macbook Air.
Use Flashblock plugin for Firefox. Just because advertisers abuse flash doesn't meean flash is bad. I only allow flash on websites that I give OK to run flash. Once HTML5 is established advertisers will abuse HTML5 and it may not be as easy to block as Flash is.
Apple's real beef with Flash is that it directly competes with their App store business and they don't want the competition oh and flash practically killing QuickTime is probably another sore point.
(probably more useful for me too, me and OSX just don't work...)
be it flash, ht5, mp4. Mov etc.
videos will always consume power. No brainer
