Solar Farms and Battery Storage

I understand that my hon. Friend is not the Minister responsible, but did I understand him correctly to say that he intends to maintain the split between green fields and roofs at 50:50? The whole thrust of the debate this afternoon has been that we do not want that maintained. We want significantly more solar power to be generated on brownfield sites and on buildings, and significantly less on fields. I would like to see it going to 70:30 or 80:20, or, come to that, 100% of solar farms being on reused land.
