That's a very good question. The culprit is Gas, whose supply contracts are tied to oil in most places. And Coal too, in Portugal and Spain it was the tripling of prices in 2007/2008 that opened the so called "tariff deficit". Also from the experience in Portugal and Spain, the introduction of Wind and Solar forced some serious upgrades to the grid, especially to link these producers to the Hydro resources. The costs of these grid overhauls are still being paid by consumers in the grid management component of electricity bills.
