Of course there is the option to use less energy. That's just silly. If you are an American, go to any other country to learn how to get by with less energy (ie smaller houses that require less heating, smaller cars that use less fuel, less commuting to begin with, smaller fridges,...).
- TeMPOraL 11y agoIn theory, there is such an option. In practice, no one will take it, because why should they? It's both a coordination problem and a short/long-term values problem. How do you convince an average Joe to reduce his quality of life now in order to secure some abstract better future later; a future, that will come to pass if and only if every other average Joe and Jane does the same? You can't, unless you're a god. And that point itself is irrelevant anyway. I too recommend watching that TED video[0] 'pdkl95 linked. The first world can try and reduce their energy consumption all they want, while there's the remaining 2/3 of the population that is industrializing itself right now, who will need more energy for things like transportation and healthcare and washing machines and food production and entertainment, and that need will offset whatever we can save. And while we the first worlders have privilege of worrying about climate change - after a hot meal and a hot shower, dressed up in clean clothes that were washed and dried by machines - most of the world won't care. They want their hot food and hot showers and washing machines now, to have time to go to school and to read books to their children. They will seek power sources they can get. All this makes current anti-nuclear advocacy outright dangerous to survival of technological civilization[1]. We should be pushing nuclear for baseline and renewables on top for peak loads, and slowly phasing-out coal altogether (and maybe pouring some more money into fusion research as well). We should be doing it right now, gaining more experience with building and maintaining safe nuclear plants, so that maybe developing countries could even skip coal altogether and go straight for nuclear+solar. But instead, we got a lot of people irrationally afraid of nuclear power, thus endangering their own survival. RE going to another country - I live in Poland, so I do have a perspective on how to live on less energy than an average American, though we still use a lot of power here.

[1] I initially wanted to write 'mankind', but humans are a resilient species and will no doubt survive even total civilizational collapse. Yes, there will be a world of humans. But it won't be a world any of us would like to live in. I like my pizza, showers, Emacs and an air-conditioned office, thank you very much.

I took that "how many earths does your life style require" - the evil half of my brain thought "if my lifestyle requires 1,5 earths, then it would be sustainable with one third less people than we have not"... Afaik China for example is trying to actively manage the population growth/consumption problem, and sometimes they managed to introduce some environment friendly things that took other countries decades (like making filters in car exhausts mandatory, making plastic bags illegal, and so on). Not that China is a model of environmentalism, just saying that it's not a given that third world countries have to take the same route to modern living as US+Europe. As for why would anybody save energy: it doesn't always have to equate less convenience. For example, even if you gave me the biggest possible car, with some magic CO2-neutral power source and what not, I would still not like commuting. So a solution that involves less commuting could both save energy and be more convenient (for example cool new houses could be build that make it more attractive to live in the city - in fact less cars would make living in the city a lot more attractive). In general it seems to me that if "convenience X" involves a lot of energy, it will also involve a lot of nuisance (machines that make noises or need a lot of attention - lots of energy passing through it means likely it will break down sooner). Or better insulating your house could simply be cheaper than paying for the energy to heat it - why wouldn't you then choose to insulate the house? And so on.
- pdkl95 11y ago> Presumably then controlling population growth I take it you still haven't seen that TED talk. A key point Hans Rosling makes (which he expands upon in greater detail in several of his other talks). In this talk, he explains ... there are two things that can increase the energy use. First, population growth. Second, economic growth. Population growth will mainly occur among the poorest people here because they have high child mortality and they have many children per woman. ... You may not have noticed, but China hasn't been very successful at legislating population growth. Meanwhile, some areas have slowed their population growth. Japan is actually concerned that they are losing population. The way you control population is \to bring people up to a standard of living that no longer requires having large families (i.e. for farm work, etc). China knows this. They aren't stupid - they certainly understand the costs of allowing terrible ("equivalent to a pack/day cigarette habit") smog. China also understands that if they can stabilize their population by raising their lifestyle. Hence they are using incredible amount of coal as a short-term workaround while they work on the largest public-works infrastructure projects in the world (e.g. Three Gorges, their current breeder reactor project). > some magic CO2-neutral power source A nuclear power generator is not magic. > save energy You say this as if engineers aren't constantly creating new ways to make energy usage more efficient. Of course they have - engineers hate energy waste. We have been slowly improving efficiency. Obviously we should continue this process, but it will never be enough to significantly impact the the total energy used in the world. > it seems to me that if "convenience X" involves a lot of energy, it will also involve a lot of nuisance This is absolutely not true in general. Many things oonly become possible when you reach a minimum of energy.
