  Hello, for gas, it’s piped directly to the power station. That’s probably the most economic way to do it, because once you build your pipelines and have all that set up, it doesn’t cost too much to maintain it. For oil, it’s either pipeline systems or by tanker. I think tankers are quite inefficient, but in the UK only a very small amount of power is generated from oil power stations, so there’s not much point in building a whole network of pipelines to transfer oil.
