How Much Energy Powers a Good Life? Less Than You're Using, Says a New Report (npr.org) 267

How much energy does it take to have a good and healthy life? A new Stanford University study has found that the answer is far less than the average American is using. From a report: Comparing energy use and quality of life across 140 countries, researchers found that the magic number is 75 gigajoules a year, or less. For context, one gigajoule of energy is equal to about 8 gallons of gasoline. Americans use 284 gigajoules a year per capita, nearly four times that much energy, according to the new research. "That suggests to me that we could nudge energy use downwards in a bunch of hyper-consuming countries and not just make a more equitable world, but perhaps make ourselves healthier and happier," said lead author and professor of earth system science Rob Jackson. The link between more energy and better quality of life is established. Globally, around 759 million people lived without electricity and 2.6 billion without clean cooking fuel in 2019, according to the World Bank.

    We can produce abundant low-cost energy without cutting back. Everyone on the planet should be able to use 284 gigajoules or more per year if they want. All it takes is the political willpower to build the power-generation infrastructure.

    We don't have to cut back, and the developing world should absolutely not be asked to.

    • American consumerist culture dictates that everything has to be bigger & more abundant. Houses are bigger & more expensive to heat & cool, teenagers get cars rather than walk, cycle or take the bus, Americans live in huge sprawling suburbs so that everything is miles away & the only way to get to anywhere is to drive, Americans drive trucks to work, the supermarket, & the mall, Americans throw away millions of tonnes of perfectly edible food & still manage to get morbidly obese, etc.
      • Most of what scientists & campaigners are proposing would make the world a nicer, cleaner, greener, safer & more equitable place for everyone to live, including Americans. Why are so many Americans against that?

        Because your proposals necessarily lead to a poorer and less advanced society where the elites get to do what they want, each consuming thousands of times the per capita energy of the poor, while the working class fights for the scraps. We Americans want what we have for everyone, and there's no reason everyone can't have it.

        Think abundance, and drop the malthusian bullshit because China and India are not about to cut back any time soon. We have virtually limitless resources and all we need is political wi

      More energy production = more fossil fuels burned, more pollution, more warming, etc. Why would you think everyone on the planet should be allowed (able?) to consume that much energy?

      Do you have a hidden source of unlimited clean energy? I doubt it.

      Even if you did, say if we had nuclear-fusion plants, then we'd be experiencing another boom in energy usage, which would only stop when the energy we produce starts heating the world to unbearable levels again (not through CO2 but because energ

      It's cheaper to just use less energy though, and you end up with a better quality of life too.

      Take insulation as an example. If you properly insulate your home you don't need so much heating and cooling. Your home is always a pleasant temperature, you aren't fighting it and don't have draughts or warm and cold areas. You even get some sound insulation for free. You have more disposable income because you spend less on energy.

We could also work towards a culture that throws less away and uses things less like single-use plastics. Maybe get away from "buy it, use it, it breaks, buy a new one" mentality that some appliances and tools are a part of (some things just seem to be designed to break or not last very long).

          My father and his sister were raised (by both parents) in a 900 sq. ft. house. I couldn't imagine trying to raise two children in a house that small today. Of course, we probably spend more time inside than they did.

        If you're going to consider the entire chain, make sure to do it on both sides.
        For ICEV, there's the mining of rare metals for calatysts, the production of hundreds more parts (ever been to an engine foundry?). And the fuel itself: to refine 1 kg of oil into its end products, another kg or so of oil is burned. Then there's transportation, etc.

        RW reports indicate Tesla batteries are good for pretty close to 1 million miles anyway.

  • ... and you will be happy.

  • 284GJ are 78888KWh, that's about 6574 KWh a month, I use for a family of four 636KWh a month (roughly, checked the last couple of months), so a per capita use of 159KWh of electricity (not counting cars). Isn't that a bit too much energy?

    Even 75GJ is about 20833KWh, which is a whooping 1736KWh a month for one person!

    Even if I add another about another 100KWh each month to account for a car it's still an awful lot.

      Is your heating source electric and if so, how has your climate temperature been? How hot will your climate get in summer and how is your energy usage then?

      Also, a family of four will look better for per-capita than someone living on their own in a house, as air conditioning and heating won't change that much for 4 versus 1 person, and those are generally the largest energy uses for a household.

      On cars, 100Kwh is about 3 gallons of gasoline. It's not unusual for a commute to burn 40 gallons in a month, so

      No you don't. That's what you pay your power company for a residence.

      All the things you buy, all the places you go, and all the food you eat have additional energy costs.

      Total country usage / total country population

    • You forgot plane flights, but more importantly indirect use - fuel for making concrete for roads and buildings, fuel for making fertilizer for crops, and fuel for transporting trinkets from Amazon. The numbers are total country energy divided by the population size, so overheads get included (though perhaps not those for producing those trinkets in China).

  • Without tanking quality of life or costing a fortune, I mean?

    Some quick calculations for myself:
    1 GJ == 278 kWh, I have a 2,000 sf house with electric heat, hot water, and range, so fairly average
    My power bills indicate a yearly usage of ~40-50 GJ/yr electric, with 80+% of that being for a/c, heat, hot water, cooking, and refrigeration
    Since covid, I only burn about 4 gal/wk or less of gas (100 mi/wk of inefficient short trips to the store, etc.), for another 25 GJ/yr or so

    Just those two things total 75GJ, n

    • Indeed; I thought my household is pretty efficient (and it is, by US standards). In direct use, my family of four used 100MCF natural gas in the past 12 months, about 6000 kW-hr electricity, and roughly 1000 gallons of gasoline across two vehicles. This doesn't count indirect use like all the energy used to make or deliver any of the other goods and services we used.

      The conversion factors I found puts this at about 64GJ/person per year of direct use for my family. I don't know how to reduce this much fur

    I'm curious how the energy use of the average American compares to the average energy use of all Americans. I suspect that these numbers are pretty skewed by the top 10% or even 1% of Americans. So if the average American reduced their energy consumption, it would have much less impact than the most energy using Americans reducing their use to be on par with most of the rest.

      A lot of it is because in America you have to drive much further than you do in most other developed countries.

      Japan is a great example of how to reduce the need to drive everywhere. They don't have strict zones where only homes or only offices or only industry can be built. Most people live within walking distance of shops and public transport, and the public transport is both cheap and frequent. Legendary reliability.

    Why not spend our energy doing that instead?
