Lights are just minor issues. The bigger issues is where is renewable coming from. I agree that it is a complete waste of farmland to put solar panels on it, when we can put wind turbines instead and produce both electricity and food. I also agree that nuclear is needed and it is actually an important tool to bridge the gap between the renewables we can generate and the electricity we need.
However, the concern is all about cost and reliability. Renewable and nuclear stations cannot increase capacity in a short time like coal or gas do. So if there is a spike in the need of electricity, we are going to suffer power curs. On the other hand, building so many nuclear stations for spare electricity is expensive and uneconomical. In addition, many of our infrastructure is lacking behind in terms of the electric efficiency and the potential to power in a green way (e.g. trains). That's when cheap imports come in, no matter labour or materials, if we cannot afford to hire our own men and produce our own materials, then we can buy from someone else. On health and safety, those labour are imported, so doesn't really matter right? At least they don't deserve as much protection (see if there is a way to exclude them from echr and other provisions, such as right of union and minimum wage through parliamentary legislations. Only leave basic basic labour protection intact). On other practices we can evaluate item by item, and keep our costs down. Only with this method, we can stop this urban decay and be ready with our next generation infrastructure.
