My electricity is rather cheap here in the US(Dallas). It's averages around 7-8 cents a KwH. The problem I face is delivery and b.s surcharges. It can easily double my rate to around 15-16 cents a KwH.
The marginal cost of generating electricity is different than the fixed price of maintaining the local grid infrastructure serving your home
What I don't like about this setup is that there's little incentive to conserve energy, invest in solar, etc. On the plus side, whenever I get an electric car, my "gas" will be practically free.
