While it's a lot of power being used, it's pretty much all automated, versus any other currency that takes a lot of manual labor. Bitcoints biggest flaw in my mind is that there is no trust built in. After each transaction it should be possible to give a rating, so that each wallet/account has a reputation, it could work like "Pagerank". Trust is essential to Bitcoin and Bitcoin markets usually has either public trust, or rating and escrow added on.
