Energy Bill

Perhaps I may suggest that if the cap fits, wear it. More seriously, as regards whether the specified period is 30 years, 20 years or whatever, I worked briefly on North Sea oil projects 30 years ago, some of which did not last that long. My noble friend declared her interest and I am sure that windmills will need regular servicing in that time. The key question after they are built is whether they will continue to operate, produce good electricity when we want it and make a good return for their investors. We have had a useful debate and I shall mull over what noble Lords have said. I beg leave to withdraw the amendment.
