If you want to get at the truth here you need to read T Stephens comments. They are much more intelligent than the main article (despite being written while he was on a phone call). Philip Davis engages in an awful lot of hysteria and shell games in his discussion. Manipulation of the natural gas and electricity markets are irrelevant to this discussion. His explanation of how prices are set is wrong, as T Stephens points out. And I haven't seen any of the Chicken Littles explain how speculators can affect the spot prices without taking physical delivery. Blaming this on speculation is a witch hunt.
