When I say petroleum products are a requirement for modern life, what I mean is that more than 80% of the energy driving modern society comes from fossil fuels. It probably doesn’t have to be that way, but it is. You definitely can’t say that for cigarettes.

I think that you raise a valid point, but also that you’re far too optimistic about renewables.

The people of HN are indeed very tech focused, and I believe that such optimism about energy transformation with renewables may be more difficult to foster if this forum were called “Engineering and physics news” simply because technologists tend to suffer from the “Law of the hammer” problem.

There are very real engineering challenges with renewables that may very well preclude the kind of dramatic progress you’re referring to. Solar and Wind for example require huge amounts of land, and have a fairly high materials throughput as their lifespan is typically only 15-20 years. All of that effort is spent gathering a diffuse source of energy. There are very real physical limits to how much energy you can gather per square foot, per kg of silica, concrete, or steel.

I think your sentiment is correct about nuclear though, which makes me wonder how much big oil has been funding groups like the Sierra Club et al. who have spent nearly half a decade campaigning against nuclear energy.
