Thank you for that question. This is a very complicated problem, because as we go as fast as we possibly can in the transition to renewable energy, one of the things we also need to do is to keep the lights on. At the moment, Wales is quite reliant on gas-fired power stations and gas-sourced energy in order to do just that. We obviously have to have a transition plan in place, and that transition plan has to work for everyone. It has to keep our industries running and our lights on. What we have to do is we have to ramp up the amount of renewables that we have coming on stream, at the same time as ramping down our reliance on fossil fuels of any sort. We've already removed coal-fired power stations from Wales early on. That was great that we did that and I'm very pleased that we did, but, obviously, it means that we've got some reliance on gas in order to have what's called baseload energy. That's energy that can be switched on at the drop of a—literally at the flick of a switch, when everybody goes to put their kettle on at 9 o'clock at night, for example. So, there are big energy surges in the country. We know when they are, but they can't be predicted to the point where we can turn renewables off and on. Sometimes, the sun does not shine and the wind does not blow.

One of the big programmes that we have running in Wales, alongside a number of Governments across the world, is the quest for baseload renewable energy, which is renewable energy that can be turned on at the flick of a switch. That is why we have a tidal lagoon challenge and a number of marine energy challenges going on in Wales, because it seems that, to everyone, marine energy possibly holds the key to baseload renewables. I very much hope that we will be able to capture for Wales the start of a global industry in renewable baseload. But, until that time, we absolutely have a duty to keep the lights on and our industry and businesses working with the energy supply that they have. I appreciate and have a lot of sympathy with the thrust of the Member's question to me, but, obviously, we are attempting to put one slider up while we slide the other one down, and we have to absolutely make sure that we do that in the right proportions.
