- Henri Lefebvre, The Right to the City — In brief, the right to the city is the right to the production of a city. The labor of a worker is the source of most of the value of a commodity that is expropriated by the owner. The worker, therefore, has a right to benefit from that value denied to them. In the same way, the urban citizen produces and reproduces the city through their own daily actions. However, the the city is expropriated from the urbanite by the rich and the state. The right to the city is therefore the right to appropriate the city by and for those who make and remake it.

why they talking about wasting light like its a finite resource?
Wasted light in this context is light that is not serving a purpose. For instance in my neighborhood there is a house that has security lights that shine well beyond their property lines and are triggered on sensor from across the street movement. These lights also illuminate upwards which provides no benefit. Simply controlling where light shines if you must have it is a good step to being a good neighbor and is better for nature as well.
unwanted light might be a better description
Oh I agree. Just was trying to provide how I interpreted the article.
But it IS a finite resource. To produce light, you need energy. Even if you use renewables, you can only cover so much area of the planet with solar panels and wind generators. In a world run on electricity that is produced by limited means, we should consider where we want to use each kWh ('bag of electricity'). Do you really want to render that image? Have that status light on all day? It's small things, but they do add up.
Youre underestimating either how much electricity we can generate, or how efficient lights are nowadays. Way more energy is going into heating applications.
So just because more harm is done with heating we shouldn't care about this waste? Small differences also make a difference, especially if the wasted light does more harm than good. If your roof leaks in two places you don't just go a fix the bigger leak.
