@paulk The claim is untrue at face value, at least for the consumer, since the markets are linked. But there is a point here that the less we depend on fossil energy, the less the oil prices matter to the consumer.
@max For the record, my political opinion is that it should be as you say. Electricity should be sold reasonably close to cost, and regulated as such, not traded on exchanges where the goal is to maximise profit. Energy is a common good and an essential resource.
